See you around?

Everything as always and yet completely different: that's my personal motto for the upcoming trade fair in Friedrichshafen. I have been attending InterDive for 13 years now.

Many years now as an exhibitor on site. This year, going to the trade fair is particularly difficult for us, as our son has to go to school while mum and dad are away. As in previous years, grandma and grandad will be stepping in - that will work, no question. But it's different let's see how it works. No less exciting is the question of how the fair will "work" this year.

The lamentations of recent months about low sales, a lack of new training and a lack of interest in travelling - will this be reflected?

Also very exciting for us: the visitor numbers.

According to the organisers, last year's concept - one ticket for the Interboot and InterDive trade fairs, which take place at the same time - was a success. I will simply test whether there is interest in the trade fair here at this point.

Would you like to attend the trade fair on Lake Constance? Then write to me. I'm giving away ten one-day tickets. Write to me by 15 September 2025 if you want to be in the draw.

And if you don't get the free ticket, you're still welcome to come to InterDive. And it's best to visit us directly at our stand, where we'll be offering our trade fair subscription again. That alone is worth the visit. And feel free to exchange a few comforting words with my wife

(because of the school child). There will also be exciting stage discussions and presentations again this year. I would also like to take this opportunity to thank you once again for the extensive feedback on the last editorial topic "Where have all the divers gone?". Even if we didn't find an ultimate solution together, many of us would know where to start. But that's another topic for a future issue.

And now please set off on a journey of discovery through this magazine, hot off the press. In addition to new destinations, we have also tested some really new equipment concepts for you. I also wish you a great start to the late summer, which will send me into the water in my lakes around the corner.

HOW DOES THE "BUBBLE BOKEH" WORK? Tobias Friedrich: In photography, bokeh is the term for a blurred background in an image. But what does it also mean? That the background has a blurred effect. It can simply be monochrome, have a colour gradient or contain what is known as "bubble bokeh". The circles or "bubbles" in the background usually come from reflections that turn into bubbles or circles in the blur.

In photography over water, these are often reflections of the sun in a water surface. However, the reflections need a certain distance so that the bubbles, circles or "bubbles" really come into their own. In addition, specially designed lenses such as the Meyer-Görlitz Trioplan 100 mm produce a particularly beautiful "bubble bokeh". However, as the distance to the subject must be relatively small, the Trioplan, for example, does not produce the desired soap bubbles.

In addition, the close-up limit of the Trioplan is quite wide at one metre, which is not sufficient for most small subjects under water. A close-up lens must therefore be used in front of the camera's macro port in order to reduce the distance to the subject. The lens is also purely manual.

However, to achieve the best "bubbles", you can set the aperture to f/2.8 and leave it there. It is more difficult with the focus, for which

Seacam fortunately offers a focus ring. Nevertheless, the subject should of course remain as still as possible in order to have enough time for manual focus. Otherwise, you can also focus by moving the camera forwards and backwards over the distance to the subject. Due to the open aperture and despite the fact that most cameras can be set to ISO 50, a lot of light falls on the sensor, sometimes too much, especially when photographing against the light. A light grey filter can be screwed onto the lens before the dive to reduce the amount of light falling on the sensor.

Another option is the new underwater flashes from Seacam, which offer flash synchronisation of up to 1/8000s and can therefore also reduce the incidence of light. As always, the same applies here: practice makes perfect. Finding the right background and using the Trioplan underwater is not easy.

DIVING THAT STAYS. TRAINING THAT FITS ... ... is the motto of the i.a.c., the German diving organisation that introduces itself here.

W

henyoustart diving, you don't just want a licence. It's about experiences, confidence - and, of course, having fun with the training. We show people a new hobby that often accompanies them for a lifetime. The International Aquanautic Club, i.a.c. for short, was founded in 1987 and is now a second-generation family business. We are active in over 30 countries worldwide, ISO-certified, internationally recognised - and yet we have remained "personal". With us, diving training works with clear objectives, but also with room for manoeuvre for the needs of each individual diver. Our dive centres and instructors know this: Anyone who needs us gets feedback - quickly and directly. By phone, email, at events, trade fairs and via our WhatsApp channels.

T Anja Kuschel

dive centre works differently. And that's exactly what we take into account. What counts is the result. And that is based on quality, not on rigid procedures. With stable, fair conditions that focus on long-term partnerships rather than price pressure.

Digital - but well thought out Our i.a.c. e-Academy enables learning that is independent of time and place, clear,

practical and multilingual. And because we don't want divers to be forced to install yet another new app, we are taking a different approach: certificates directly for the Apple Wallet. Without detours or technical frustration, available on any device. The certificate is simply there - in the cloud, on every device, automatically backed up. This is what our digitalisation looks like, userfriendly and focused on the essentials.

At eye level and with reliability Our training system ranges from children's diving to the complete recreational diving programme, freediving, sidemount, nitrox, trimix, rebreather and instructor trainer levels. New to the programme is our Sport TEC area, which simplifies the entry into technical diving - for all those who want more, but without pressure. We focus on trust and personal responsibility: our instructors are given the training goal - but not the way to get there.

Every person learns differently, every DIVING.COM

i.a.c.Managing Director Henrik Balzer is responsible for the direction of the diving training organisation.

Diving & travelling a connection with potential What sets us apart from many other training organisations: We can not only train we can also "travel". With our own travel division "Tu.R." - Tauchen & Reisen (tauchen-weltweit.de), we combine training and holidays in a way that comes directly from practice: Instructors can accompany groups and earn additional money. Dive centres benefit from prepared trips, booking campaigns and targeted demand.

Customers receive an all-round service (group trips, individual diving packages or classic package holidays). Tu.R is not just a tour operator - it is a tool with which our partners can actively work and expand their reach.

B2B programme Building bridges worldwide Our community thrives on genuine connection. That's why we have launched a B2B programme for dive centres worldwide. This gives instructors and dive centres the opportunity to get to know new partner destinations personally, see the quality and procedures for themselves on site and establish long-term partnerships. This creates trust, saves time and ensures that contacts become real partnerships. i.a.c. is not a platform or a franchise, but a network. We think diving training further because we know how diving really works. Not from the top down - but always on a shared level.

DO SHARKS HAVE A PERSONALITY ?

Are predatory fish comparable to our pets such as cats and dogs? Most studies and most shark experts are convinced of this and have many of their own experiences to confirm it. However, we do not know how many of these behaviours are influenced by food-specific, species-specific or intraspecific behaviour or by environmental factors. The same applies to the question of whether a shark's personality can be captured at all with the character descriptions of the human species (courage, fear, shyness, etc.). All that remains is the fact that "not all sharks are the same". Their behaviour remains unpredictable, and this always makes a close encounter a risk. Some come closer, some don't, some are pushy and none of them care what character traits we want to attribute to them. They remain extraterrestrial aliens for us - in the truest sense of the word. But at least one thing is certain: unlike the aliens in the film, they don't want to hurt us. Accidents involving humans are just that - accidents, oversights or mistakes. We humans are not part of the sharks' prey. One of the many pieces of information about sharks from the exciting shark books by Sharkproject founder Gerhard Wegner: Upps! The Big Shark Book and BLIND DATES - Encounters with Sharks . If you want to do something good for marine conservation, buy from the charity bookshop: ocean-heroes.shop - otherwise from Amazon.

An almost completely preserved shipwreck from the late Hellenistic to early Roman period was discovered off the coast of Antalya in Turkey at a depth of 33 to 46 metres. Hundreds of Eastern Sigillata ceramics, protected by an ancient packaging technique, have survived almost intact for over 2000 years at­.

Culture and Tourism Minister Mehmet Nuri Ersoy emphasised the value of the find for the common cultural heritage of mankind. The artefacts will be restored and presented in the planned Mediterranean Underwater Archaeology Museum in Kemer-Idyros. The discovery is part of the "Legacy for the Future" programme, with which Turkey is further expanding its leading role in archaeology.

IN MEMORY OF ALENA STEINBACH

It is with infinite sadness that we bid farewell to Alena Steinbach, who passed away on 16 July 2025 after a long, serious illness at the age of 65. She is well known to many divers through her numerous publications about the underwater world, which she created together with her husband Dietmar Steinbach. After their marriage in 1983, they began to turn their passion into a profession.

They reported in almost all German and Czech diving magazines, and for a time also in Polish diving magazines, with their hearts beating especially for the local waters. Alena was not only a talented photographer herself, but also modelled in front of Dietmar's camera countless times.

Particularly noteworthy is her significant contribution to the successful diving travel guides for the Kosmos publishing house, which for many became standard works for diving in Germany. But beyond all her successes, Alena will always be remembered for her extraordinarily friendly and engaging manner. It hurts deeply to no longer be able to hear her heart-warming laughter. She will remain unforgotten.

In loving memory, Dietmar Steinbach and friends & the TAUCHEN team

TRAVEL ° EGYPT LIVEABOARD

M/Y INDEPENDENCE II

CHARM BEATS LUXURY

T & F Barbara & Wolfgang Pölzer

What counts on this liveaboard is "soul and feel-good character". Our authors found out what regular guests mean by this in the deep south of the Red Sea.

TRAVEL ° EGYPT DIVING SAFARI

H

ow many times have you been on the Indy II - as she is affectionately known by insiders? Most of the guests travelling with us have been on board at least five times, one even a whopping 16 times. over 70 per cent regular customers speak a clear language. This success is certainly due in no small part to experienced and likeable tour guides such as Annika Rabe, who has been part of the team for ten years.

Tradition meets innovation: the rabbits are a long-standing trademark of the company and will remain so (picture above). In contrast, the company remains flexible and open to new routes and spots, such as the recently discovered wrecks in the very south of Egypt.

The journey is the destination With permission from the harbour authorities in our pockets, we set off from Port Ghalib on time the next morning. The usual familiarisation dive follows and then a comparatively beautiful coral garden a little further on in the Abu Dabbab region. But then it's time to "make nautical miles". After all, we want to go deep into the south of Egypt to the Elba Reefs, which are still very little dived, right on the border between Egypt and Sudan. An impressive 400 kilometres through the Red Sea lie ahead of us.

Fortunately, the long distances are usually travelled at night so that no dives are lost.

The following morning, we wake up off Rocky Island, a small rocky island around 60 kilometres south-east of Ras Banas. It is known for its spectacular steep walls with sharks and big fish in places exposed to the current. However, due to the glassy sea and the almost eerie lack of any water movement, we have to make do with lush soft corals, colourful reef crevices and small caDIVING.COM

verns. Large Napoleons, small schools of jacks and fusiliers seem to miss the current just as much as we do. So let's cast off and head south!

Mackerel casserole off Elba Once again, the powerful engines of the M/Y Independence II run all night long.

On the third morning on board, we hear in the briefing that we have reached our southernmost tour destination: the Elba Reefs.

They are a huge complex of three larger reefs and a number of smaller ones in the border area between Egypt and Sudan. Although it has been known for years, this region is still relatively rarely dived, mainly due to the long travelling distance. The only ship far and wide, we then jump directly from the dive deck onto a coral plateau in the 25 metre range. We are greeted by stony and fire corals in surprisingly good condition, with some soft corals in between in a moderate current. We try to gain some depth through a labyrinth of boulders and small towers. A large group of bright yellow barbels is heading straight for us. As hectic as ever, they scurry through the reef with their fins curved just above the bottom.

They use their long barbels to track down hidden worms, crabs and small fish, which they devour in a flash. Close on the yellow hunters' heels or fins, however, is a lemon trevally that lives up to its colourful name and wants to snack on the startled prey. As soon as the chase has been captured on film, a much larger shoal attracts our attention. With the current behind us, we drift away from the reef into the 30-metre depth range, only to suddenly find ourselves in the middle of a school of adult bluefin mackerel. The impressive predatory fish briefly shoot curiously around us and are then almost seamlessly replaced by an even larger number of shiny silvery bigeye jacks. The fish bodies, bursting with strength, dance around us at not even arm's length and at a horrendous speed. After just a few seconds, the spectacle is over and we are alone again.

What a spectacle! And if it wasn't true, it would be a good invention: As if out of nowhere, a horde of yellow-speckled >

Type of vessel: Wooden motor yacht Facilities: ten cabins for a maximum of 21 guests: six lower deck cabins, three main deck cabins and a large suite on the upper deck. All are functionally equipped with self-regulating air conditioning and a strikingly large bathroom/ WC. The layout between the dining room on the main deck and the saloon with sofas and flatscreen on the upper deck is unusual but cosy.

TRAVEL ° EGYPT DIVING SAFARI lemon trevally suddenly swims towards us from the depths. They are only half the size of their relatives that swarmed away from us before. But they stay with us longer. As the crowning glory of this incredible mackerel run, three specimens of a fourth species of mackerel scurry past us in the shallows not far from the boat - the rarely encountered snub-nosed pompano.

Wine and salt Half a dozen dives later, we have a good overview of the Elba reefs and have seen more shoals of mackerel, barracuda, surgeonfish, red and black snapper and, of course, bannerfish pass us by. Steep walls, plateaus, towers with different coral growth, huge gorgonian fans, unusually large fields of whip corals and even interesting caves in the reef top and a few white tip reef sharks also presented themselves photogenically. The highlight of the region for many, however, is the wreck of the SS Levanzo: the Italian steel steamer has developed into an impressive artificial reef in the hundred-plus years since its disastrous contact with the eastern Elba reef. Lying upside down with its bow at an angle on the reef, the gigantic four-bladed propeller alone is the highest point in the 20-metre range. Like the rest of the wreck, it has disappeared under a thick layer of colourful sponges, shells and soft corals. We continue along the hull of the wreck to the break-off edge at a depth of almost 40 metres. Whole bushes of black coral sprout from the larger bow section, which lies on its starboard side, but is unfortunately mostly below the recreational diving limit and reaches down to a depth of just under 70 metres. Even with excellent visibility, the dimensions of the 113 metre long freighter can only be guessed at and only a fraction of it can be explored in one dive. As it is much shallower, we venture into one of the aft holds. Barrels of salt and crates of Chianti wine bottles were part of the cargo on the SS Levanzo's journey from Genoa to Durban in South Africa. Individual empty, colourful wine bottles are still easy to track down. To recognise crates and barrels, you need more

imagination or have to dive deeper into the ship's upside-down belly. We climb up the rope from the propeller to the stern of the Indy II just within the no-decompression time, curiously eyed by an eagle ray as it flies past.

Aircraft discovered On the following two days, we gradually head back northwards through the Red Sea. The route includes secluded coral gardens and many fish encounters. But we are particularly impressed by a special wreck.

If a ship has no business on the seabed, an aeroplane has even less business down there. Nevertheless, not far from the coast in the middle of nowhere, an excellently preserved seaplane rests on a flat sandy bottom just below the water's surface and makes a fantastic diving spot that is even suitable for snorkellers. The almost 20 metre long aircraft wreck is an American Grumman HU-16 Albatross, which is said to have been privately owned at the time of its crash and sank in 1981. Known to fishermen for many years, but far from the usual routes of liveaboard vessels, the submarine Wreck fever: What could be more fun than exploring a shipwreck that has barely been dived? And at beginner-friendly depths.

gem was only discovered just over a year ago and has only been dived very little so far. With only one wing broken off and both propellers missing, the former amphibious aeroplane could not be more beautiful for us lying on the seabed. Tentatively overgrown with stony corals and sponges, the aircraft's aluminium still shimmers silvery in the sunlight at a depth of ten metres. The rear wing even rises to a height of four metres, while the sandy bottom under the wings indicates a depth of almost 14 metres. Through the broken aircraft windows, you can catch a glimpse of the colourful cockpit, where glassfish, jewel groupers and a scorpionfish have taken over the helm. Further back, hatchet-bellied fish spend the day in the remains of the former seating. We circle the aircraft several times and are even impressed by the underside of the wings, which provide shade for many a fish as a colourful overgrown shelter.

Ship car park Just an hour and a half by boat, following the coast to the north, another wreck awaits us late in the afternoon that has probably been dived even less than the Albatross aircraft. A 20-metre-long ship relic rests here on the sloping sandy bottom at a depth of just five to 20 metres, perfectly parked between two reef towers. Nobody knows for sure. But the Turkish steel ship "Sabri Baba 1" is rumoured to have sunk in a heavy storm three to four years ago.

That's fine by us. Because the fishing vessel, which at first glance appears to be completely intact, also proves to be extremely interesting and photogenic for divers' eyes.

Even its nets are still hanging in place, moving slightly in the swell and giving the wreck a mystical atmosphere in the twilight. The short time under water was enough for Mother Nature to decorate the shaded sides, railings and pipes with bright red sponges. The well-streamed outer areas, such as masts and superstructures, are already overgrown with impressive stony corals. And as if in mockery, the former fish hunter has now developed into a centre of attraction and habitat for a whole host of

Winged "creatures": a real treat not only for wreck fans! The Grumman HU-16 Albatross, which sank in 1981, is partially covered in colourful vegetation and offers many fish a new home as an oasis in the sandy desert at a depth of just ten metres.

TRAVEL ° EGYPT DIVING SAFARI fish. Not only small coral fish scurry around the wreck, but also whole schools of fusiliers and a shoal of bluefin mackerel.

The daylight of the late afternoon wanes as we explore, but we enjoy the colourful life on the artificial reef until nightfall. After all, the Indy II is waiting just a few fin strokes away.

Alone on the reef For a week now, we've been the only boat for miles around at all the diving spots.

That's a great thing, especially in Egyptian waters. "Of course, that's not always possible," tour guide Annika explains, "but it's often the case with longer and more unusual tours than the majority of liveaboard providers offer." The Indy II is not alone in her company "Bluewater Safaris", which is celebrating its 20th anniversary next year. The newer and more modern sister ship M/Y "Independence III" completes the small fleet of company owner Bernard Wächter since 2022.

But the good soul of the company lives on in the Indy fleet - be it in the form of the popular Hasi mascots on the decorative rope, the ubiquitous gong instead of a ship's bell on board or many other creative ideas for embellishing a ship. The Indy also makes a very good impression in all other areas - a typical ship made by divers for divers. Practical, safe and equipped with two independent, very powerful engines. Even on the following two tour days in the well-known regions of the St Johns reefs and Fury Shoals, we are alone again. Well, not completely, because in places we are accompanied by a group of spinner dolphins during the trip.

Dance of the dolphins On the penultimate morning of the safari, we wake up lying in front of Elphinstone, the legendary outer reef around ten kilometres off the coast of Marsa Alam. Like a gigantic compass needle, the 600 metre long coral structure rises to just below the surface of the water. Both long sides drop off in the form of vertical cliffs into the unattainable depths of the Red Sea, while stepped plateaus to the north and south have already made many divers' eyes shine.

Hardly anywhere else is there such a great chance of encountering sharks and large fish as here. After two dives on the north and south plateau with napoleons, tuna, mackerel, feeding filefish and turtles, but

Tioman Island is an almost unknown diving destination off the beaten track, which is surprising, because the small, rainforestcovered island off the east coast of Malaysia offers impressive coral reefs, tropical fish galore and a relaxed diving holiday feeling. Come with us ...

T

o be honest, we didn't realise that Tioman Island even existed. Until a friend revealed this secret to us and urged us to visit. So we set off on our journey. And ended up in the village of Air Batang, nicknamed ABC and the main hub on Tioman Island for dive centres, accommodation and restaurants. The charm of this place lies in the fact that everything is right by the sea.

There are no real roads or cars in ABC. Everyone walks, cycles or rides a motorbike to and fro. Most of Tioman's dive sites are located on the west and north coast of the island and on the offshore islets. Tioman is very popular with diving beginners, but also offers experienced underwater sports enthusiasts excellent sites off the offshore islands such as Labas, Chebeh and Coral Island. We also completed the majority of our 20 dives there, usually at depths of between 15 and 25 metres. Tioman Dive Resort is the leading provider in the region. It is a PADI CDC and offers a complete portfolio of training courses from recreational diving to technical diving. The centre operates numerous boats, employs great staff and offers full dive equipment rental and sales. The staff customised our diving programme and organised various morning and afternoon excursions for us to make the most of our underwater photography opportunities.

Just over 50 kilometres east of the Malaysian mainland lies the small island of Tioman in the South China Sea. It is still little known here.

The diving spots around the island are among the highlights on this side of Malaysia.

Thanks to the exposed location of the island and the surrounding reefs, water pollution is very low, which leads to great biodiversity and health.

Lots going on under water!

Tioman Island is located in the far west of the famous Coral Triangle and is a paradise for tropical marine life. Scientists have counted hundreds of species of fish and thousands of species of invertebrates. Some of the coral reefs there are over 6000 years old and the marine habitat has plenty of healthy reefs dominated mainly by hard corals. In Batu Malang we found whole mounds of potato corals, polyp after polyp, and intricately branched lettuce corals. The field of staghorn corals in the shallows around Renggis Island made for a wonderfully relaxing afternoon close to home base.

Lots of soft corals - fan corals, bushy gorgonians and whip corals reminiscent of shepherd's crooks - could be admired at Fan Canyon, Golden Reef and Tiger Rock. At the latter dive site, there is also a huge, multi-tipped barrel sponge that is well worth seeing.

The 39 kilometre long and twelve kilometre wide island is located around 50 kilometres off the east coast of Malaysia in the South China Sea. The total area is 136 square kilometres. Tioman Island is inhabited by a good 400 inhabitants.

The island is a nature reserve lined with picturesque beaches and is largely covered by tropical rainforest. The idyllic island lies somewhat off the main tourist routes and is therefore less visited than comparable destinations.

DIVING.COM

Clownfish in purple carpet The hawksbill turtles that we often saw were very trusting, so it was easy to take pictures of them. The fish watching was also fun: angelfish and spadefish, jackfish, wrasse, fusiliers, damselfish, pufferfish and barracudas were frequently seen. The loyal school of snappers and the many clownfish among the purple-coloured carpet anemones at Pacman were a feast for the eyes! You should have macro and wide-angle lenses ready to capture all the perspectives of Tioman's underwater world. We also saw blue spotted rays and blacktip reef sharks, but would not describe Tioman as a shark destination.

The coastal waters around Tioman Island have been protected as a marine park since 1985 and may not be fished. Diving boats must use moorings or drift, as anchoring is prohibited. Tourism is the island's main economic activity and is growing steadily, so conservation of the marine ecosystem and careful management of development on land are vital to ensure a sustainable future for the environment, wildlife and the way of life of the locals. > 10°2025 DIVE

Marcus Hauck's favourite project on the local island of Guraidhoo, just 35 minutes by speedboat south of Male, proves that it can be much more comfortable and almost hotel-like.

"Diving, eating, sleeping, repeating - as comfortable as in a resort and a little island life with the country and its people," is Marcus' idea. He knows what he's talking about. He himself has been working in the Maldives for almost 40 years and, together with his Maldivian partner Jerry, runs a further four diving centres on resort islands and is a permanent fixture in the isDIVING.COM

On four levels with a proud total area of almost 1000 square metres, everything is united under one roof: diving centre, guest rooms and panorama restaurant. It will open in November with a pre-opening. Full operation is planned from March 2026. We were allowed to take a look inside in advance.

And this much can be revealed: We really like it!

Short distances Just cross the sandy road and you're on the spacious wooden dhoni. A quick nitrox check and then it's into the thin neoprene, because the good dive sites here on the east side of the South Male Atoll are right on the doorstep. Less than 15 minutes later: step forward and into the pleasantly warm Indian Ocean. Cocoa Corner - channel diving at its best. Enormous amounts of wa-

ter flow in and out of the atoll at the corner of the reef that gives it its name. Current is fish! And so we are soon greeted by a huge school of wonderfully reddish humphead snappers, followed by photogenic sweetlips. We paddle into the channel behind guide Reehan with the water just running out. Stepped sloping reef, small overhangs, colourful vegetation and full of bright red soldier fish and the odd large grouper. A little deeper towards the bottom of the channel at just under 30 metres, a huge stingray darts past and grey reef sharks patrol the horizon. Then suddenly there is movement. A swarm of fusiliers seems to panic and seek shelter between us, closely followed by a group of rainbow runners and a reef shark in a hunting mood. similar to a fox and hare, everything happens at lightning speed.

Everything in view: Directly from the striking guest house with dive centre, restaurant and view, the spacious diving dhoni takes you to the best spots in the area, which are just a few minutes away. Sharks, rays and other big fish are guaranteed.

you'd think nothing had happened. Wow, what a spectacle! And we're right in the middle of it. Feeding turtles, a sizeable school of bannerfish and a relaxed mobula ray swimming past as we surface - not bad for a first dive.

Thanks to the short distances, it's a quick trip back to the base for the surface interval. Quickly get something from the room or go straight up to the second floor and review the dive in comfort with an espresso in hand. This is what a holiday should be like!

Kandooma Thila For the following dive, don't forget your drift hook! Because now it's off to the best

diving spot in the South Male Atoll and one of the top ten spots in the entire Maldives.

The shoal in the middle of the channel between the islands of Kandooma and Cocoa is always worth a dive, regardless of the current, and is definitely worth visiting several times. Logically, visibility is better when the water is coming in. However, in outgoing water, life is concentrated on the narrow side of the reef, which resembles an elongated triangle. It is extremely difficult to describe a typical Kandooma Thila dive without going into raptures - but here is an attempt: dive into the blue and gain depth as quickly as possible. After just a few metres, we are greeted by countless masked nose doctor fish. Just ignore them and never try to scare

them away with your hand! This is because the razor-sharp blades on their tails can cause painful injuries. By the time the first outlines of the reef appear below us, they will have disappeared again anyway. Precision landing! With reef hook in hand, Reehan leads us purposefully to two rocks at a depth of 27 metres with just a few strokes of his fins. Now hook in and take a breather.

As if on the balcony of an opera house box, we sit around three metres above the stage and wait for the show. Quicker than expected, the overture begins with a round dance of grey reef sharks. Sometimes from the left, sometimes from the right, sometimes above and sometimes below us, they circle round and round, coming almost within arm's length. Curious whitetip reef sharks also mingle with the crowd, adding to the value of this spectacular show. But it gets even better! There is movement on the horizon.

At first completely indefinable, then reminiscent of a flock of birds in slow motion, until eyes and brain finally agree on a school of eagle rays. Not five, not ten, not 15 - but an incredible 23 specimens hover, glide - practically fly through the water - towards us and pass just above our heads. Beaming with joy, we turn our attention back to the sharks until the no-decompression time draws to a close, despite the nitrox. But it's not over yet. The show continues one level higher. Drifting diagonally with the current towards the shallows, which rise in steps, we cross a wild horde of jacks, which mingle with countless snappers and surgeonfish under a spacious overhang. Further up to

the next edge and hook in again. The no-decompression time is back in the green zone, bottle pressure is also right, and it's still possible to hold out for a while here in the 15-metre range amidst the teeming fish.

And believe it or not: before the final applause of our truthful fish performance, two more eagle rays float past close to our masks.

Endless choice Once we've been hooked, we naturally want to go to Kandooma Thila again and again. But the other dive sites also deserve a chance. More than three dozen dive sites throughout the South Male Atoll cover pretty much everything the Maldives has to offer, from current channels to cosy reefs,

from wrecks to several manta spots. On request, the somewhat controversial shark diving site "Shark tank" not far from the airport can even be approached, where you can often see not only lemon and spinner sharks, but with a bit of luck also bull, tiger and great hammerhead sharks in the admittedly often murky water. Guraidhoo's own manta spot within sight of our guesthouse is much quicker and easier to reach.

We try our luck in the incoming water, i.e. the best conditions, and actually encounter two of the giant rays. They circle the reef block in a relaxed manner, almost as if in slow motion, and repeatedly pause with their mouths wide open to offer the fingerlength cleaner fish every opportunity for a free parasite meal. We could watch the fa-

se that the supposed game is a mating scene. The love-struck guys vie for the lady shark's favour, trying to bite into her pectoral fin more timidly than skilfully, but unfortunately not to the extreme. The small group of sharks soon moves off in search of more privacy, leaving us behind with clicking cameras.

They have been through the Blackwater baptism a long time ago and know what the endless darkness has in store for us in the next hour: "You will love it or you will hate it. That's it!" Encouraging words before our very first Blackwater dive. With a courageous roll backwards, the dark arm of darkness finally pulls us down from the Bangka into the omnipresent gloom off Romblon.

All around us is deep black. The seabed?

Invisible. The surface of the water? Just a glimmer of light away. In this very darkness, a huge vertical animal migration is taking place. Millions of microscopic creatures rise from the depths of the Romblon Pass to the surface to feed under the cover of night. A freak parade of bizarre, luminous and often as yet undiscovered creatures. And we are right in the middle of it!

And the café offers the opportunity to experience Romblon's birdlife up close. And all without mass tourism. If you have the Philippines island on your bucket list as a diver, you should definitely have a certain affinity for macro photography and bizarre tiny creatures, often in the millimetre range. Dives around Romblon are not for the quick thrill-seeker. Those in search of majestic sharks and huge schools of fish are likely to be disappointed here. But for those who want to get involved with the small, almost invisible surprises of the underwater world there, Romblon is a true paradise. It is a world of tiny details, of quiet sensations.

One last Blackwater dive, one last plunge into the dark black. Between darkness, light and floating, a world reveals itself to us in which we forget for a moment that we are on earth.

It hitches a ride on a leaf through the maritime galaxy. The fact that this obscure scene has so much life in store for us not only surprises us, but also puts a big smile on the face of our diving guide Rosebe. And she smiles too, because the dive sites around the "Three P Dive Resort" still hide so many secrets, so many little sensations waiting to be discovered. <<

s with every journey, the first thing on the agenda was the journey itself. Unfortunately, these days Deutsche Bahn forces every traveller to plan carefully, including Plan B. In principle, however, you should go straight for plan B, as it is now less likely that trains will run on time and arrive on time. And so the journey to Frankfurt Airport involved a stopover with an overnight stay in a station hotel. Actually totally relaxed. No worries, no hopes, just play it safe, get up relaxed the next morning and take a train or

taxi to the nearby airport. And after an unspectacular six-hour nonstop flight with Qatar Airways, you land in Doha, from where it takes another 1.5 hours to land in Oman's capital Muscat. But as so often in my life of travel research, the pick-up service and I get lost at the airport exit. In the end, the odyssey of finding our way takes an hour. The reason? Small sign meets overtired, blind guest. But then it's all the faster through the Omani night towards the south on first-class roads. 40 minutes later, you are greeted by the aroma of incense and the concierge with your room key in the impressive entrance hall of the Shangri-La Al Banda.

What Oman has to offer If you browse the internet with a focus on diving in Oman, you will be promised the following: "Diving in Oman offers encounters with whale sharks from June to October, manta rays from May to September, several species of turtles such as hawksbill and green turtles as well as macro species such as nudibranchs and seahorses. Coral reefs, drop-offs and wrecks can be found along the coast of Muscat and the Daymaniyat Islands. Visibility ranges between ten and 30 metres, depending on the tides and the amount of plankton, which increases in spring and autumn. Currents vary: moderate currents can occur on the outer reefs and channels at the Daymaniyat Islands and in the south at the Hallaniyat Islands. Dive sites close to the coast near Muscat are mostly calm. Water temperatures range from 23 degrees Celsius in winter to 30 degrees Celsius in summer. From January to March, plankton blooms are common, which can limit visibility but also attract big fish." Why am I putting this here? Because my trip consisted of two parts, and the second part (to follow in issue 12/25) reflects the real reason why Oman can also be worth a pure diving holiday. This much can already be revealed: In part two, we travelled by safari boat to the Daymaniyat Islands, where a big surprise awaited me and everyone else. But now on to what you can experience when diving around the Shangri-La Resort near Qantab, around 40 kilometres east of Muscat. > DIVING.COM

SHANGRI-LA BARR AL JISSAH RESORT & SPA IN MUSCAT (OMAN) Nestled in a picturesque bay between the rugged cliffs of the Al Hajar Mountains and the turquoise blue Gulf of Oman lies one of the most impressive luxury resorts in the Sultanate: the Shangri-La Barr Al Jissah Resort & Spa. The extensive complex consists of three stylistically different hotels that are seamlessly connected and offer a suitable ambience for all types of guests.

Al Waha (the oasis) is aimed at families and impresses with spacious rooms, shallow pools, a children's club and direct access to one of the most beautiful beaches in Oman. A highlight for young and old alike is the Lazy River, which flows gently through the resort and connects the Al Waha and Al Bandar hotels - ideal for relaxing in the afternoon sun.

Al Bandar (the city) is centrally located in the heart of the resort and impresses with its elegant architecture, high-quality furnishings and direct access to the resort's numerous restaurants, bars and boutiques. Pleasure, comfort and oriental style come together here.

The crowning glory of the trio is the exclusive Al Husn (the fortress), a luxurious adults-only hideaway with a private infinity pool, private beach access, spacious suites and unique inclusive services such as afternoon tea, sundowner cocktails and attentive butler service. The cliff-top location guarantees spectacular views of the sea and maximum tranquillity for couples seeking relaxation.

The resort experience is complemented by the award-winning CHI - The Spa, a well-equipped water sports centre, diving facilities, a modern fitness centre and a sustainable turtle conservation programme, where guests can get up close to the local sea turtles with the Turtle Ranger.

Just a 45-minute drive from Muscat International Airport, the Shangri-La Barr Al Jissah offers a unique combination of oriental luxury, family friendliness, idyllic retreat and nature experience at the highest level.

Tip: Compare the prices for offers with breakfast only, half board and full board. Sometimes it is cheaper to switch to half board or full board.

The diving centre The first day. After several hours inspecting the huge, beautiful hotel complex (see TAUCHEN YouTube channel: https://tinyurl.com/ omanshangrila), we take a short buggy ride to the marina. A new building complex is being constructed here, forcing the Extra Divers dive centre to move into a temporary container facility. But the most important thing is that there is air conditioning here. The rest is as mentioned: provisional and functional. In the future, either a move to the new harbour complex or to the hotel complex is up for discussion. We receive a warm welcome - I have to smile as I write these lines because the team is really lovely - and the next two days are planned. Almost 20 dive sites, including a wreck dive, are on offer. The trips with the modern fibreglass boat take between five and 45 minutes. The spots are approached according to preference, diving ability and weather conditions. You arrive at the base at 8 a.m. for the two-tank dive trip. You will be picked up by the hotel bus or buggy by 1 pm at the latest. If there are enough guests on the list, there is also a second trip in the afternoon. Towed, washed, dried and prepared on the boat: You hardly have to worry about the equipment - the team takes care of that. This service is not only appreciated by hotel guests. Guests from other resorts and foreigners living here also use the base to dive along this stretch of coast. An overview of the base and spots is available in sound and vision on YouTube (https://tinyurl.com/omantauchen) as an on-site tour of the base.

Two things are certain: On the one hand, you can be sure that the local service at Extra Divers Qantab is first class.

The other safe harbour is an encounter with at least one turtle per dive.

There is another way: colourful and speciesrich is one side of this re­gion. On the other hand, the opposite can also be waiting. Dead sea creatures in fishing nets and visibility conditions that are more reminiscent of diving in a lake.

Diving 7 o'clock. The next morning comes quicker than expected. And so it was good to have assembled the photo equipment the day before.

This gives us time for a mini snack and coffee. And off we go in the hotel buggy from the lobby to the harbour. A little later: Suit pulled to half-eight, towel thrown protectively over the shoulder, it's off with the boat and six other guests for the first two dives. "The wind has picked up, the visibility could be so-so," Michele "Miki" apologises as soon as the boat leaves the harbour. In the end, this was completely unnecessary, and even Michele is surprised to have such visibility in these conditions. "Unusual, but great for us," he says later. In this case, good visibility means over 20 metres into the distance. How deep can you see? Rarely deeper than 20 metres at many spots here. This is due to the maximum depth alone, which only goes deeper in a few places. I am surprised: the variety of healthy corals in the three-metre range at water temperatures of 31 degrees Celsius - I would have expected otherwise. We jumped into the water at Qantab Reef. A slope dotted with boulders overgrown with coral, which then separate out on a Endemic species, families of sandy plain, no deeper than 15 metres. The highlight here is "some of the largest table corals in Oman, which orcas passing by the boat are still healthy", promises and shows Miki a little later. and whales in the distance: The landlords of this spot seem to be moray eels, which the Gulf of Oman is one of accompany and eye me every metre of the dive - always those great surprise pafrom a different hole or swimming freely. Unfortunately, the spot and the dive come to a sad end. A set net has ckages where you are offecost the life of a green turtle. "We are not allowed to red everything or nothing in touch the nets, but we pass these finds on to the authoterms of diving. The sultanarities. Fishing has a high priority in Oman, far above te also has so much to offer environmental protection," explains Michele regretfully. On the other hand, there is a field with dozens of above water that you should concrete blocks that have been sunk into the vast exuse your stay there for more panse of sand as an artificial reef. The second dive at Jisthan just a diving holiday. sah Island is even more astonishing: huge fields of healthy leather corals interspersed with dozens of hard corals as far as the eye can see. it "swims and swarms" everywhere.

And, as promised before the dive, well over a dozen turtles of all sizes. Sleeping, eating, swimming. Great! They are joined by cuttlefish in a mating frenzy. A female surrounded by five or six males.

Sometimes racing quickly through the reef, sometimes slowly "tentacling" each other. I was pleasantly surprised by what was on offer underwater. Great scenarios, lots of fish. The hard corals in particular, but also the Dendronephthya soft corals that grow back in many places, present an unexpected diversity - even if it is only a snapshot. What the dives could not fulfil was the expectation of having to dive in a murky green soup. But don't worry, you'll get a glimpse of it the next day.

One night later, we head out again early in the morning: this time a little further south-west to the wreck of the naval vessel Al Munassir, which sank in 2003. However, as I will be diving the wreck the following week of my visit to Oman anyway, we save >

The summer and winter monsoon drift fills the waters of the Gulf of Oman with nutrients. This is reflected in an enormous diversity of species.

This is especially true for cephalopods, which were in the midst of mating fever during our stay. There is also plenty to discover for fans of "little things", including the countless harlequin shrimps (centre image).

ourselves the exploration and dive the "Plug Point" reef right next to it: turtles in the coral garden with eagle rays flying past - what a wonderful morning walk in perfect visibility conditions and completely current-free at a maximum depth of twelve metres. This spot is a must! We are then served a taste of what "different diving" can look like in Oman at the last dive spot: "Purple Haze" is the na-

me of the dive site, which begins along a steep wall that ends at a depth of just under 25 metres and is overgrown with purple whip coral from top to bottom. When you jump into the water, you come to a sobering realisation. You should stay close to your buddy here!

As if you were walking through a snow flurry with monster snowflakes in the depths of winter, we dive into the murky, deep green water along the steep wall. As far as you can see - just 1.5 metres - it is teeming and growing in every corner. After about 15 minutes and a small bend, someone suddenly switches on the light, sweeps the snow flurries aside and presents a coral garden whose diversity is similar to the spots on the first day of diving. A work of witchcraft!

"You never know what you're going to get. That's what makes diving here in Oman so exciting. Sometimes positive and sometimes negative," Miki comments on my surprise when we end up visiting the nursery of some whitetip reef sharks just before the harbour.

Personal conclusion The Sultanate of Oman surprised me positively on the first few days of diving. I was definitely there at the right time and, according to Miki, had very good diving conditions. But I was also told and shown that you can also meet orcas and Bryde's whales here. A

week before my arrival. The diving is suitable for beginners, but also offers enough variety for experienced divers. With the ShangriLa Resort, it's also a perfect place for a family holiday. I would have liked to go on excursions into the hinterland and to the capital Muscat if I had had more than just three days. The region with all the highlights around it is too good for a pure diving holiday. In the end, it was time for me to pack my bags on the third day and head south, where the safari ship Oman Explorer was waiting. But that's another story (then in TAUCHEN 12/25). <<

CAMERA HOUSING DRIFTS THROUGH THE NORTH SEA AND RETURNS TO ITS OWNER What a stroke of luck! A diver lost his expensive camera housing set (Sony & EasyDive housing) during a dive on the Jutland wrecks in the middle of the North Sea. A week later it was found 279 kilometres away on the beach at Skagen - undamaged and with a full battery. The finder recognised the valuable housing and contacted the manufacturer, who traced the owner from the United Arab Emirates. The camera was returned in an unusual way. A rare stroke of luck that shows how unlikely such positive coincidences are - and that honest finders make all the difference.

New edition of the classic fin with a clear focus on efficiency, comfort and versatility.

heAvanti Quattro+ from Mares was a real perennial favourite on the fin shelf. Generations of scuba divers and diving instructors worldwide have relied on its powerful propulsion, solid construction and robust handling. But at some point, the time has come even for classics. With the Avanti Quattro 4X, Mares is now introducing the next evolutionary stage and promises: more thrust, more control, more comfort. We tested the new product in various configurations - indoors and outdoors, with a wet suit and in a dry suit.

The first impression You notice it as soon as you unpack it: The fin comes in a reusable mesh bag, as you would expect from more sustainable product lines. The first haptic impression is consistently high quality: the material has a good grip, the finish is clean, the shape is familiar - and yet new. The large "X" made of reinforced rubber above the instep is particularly striking and not just visually different from its predecessor. It gives the newly designed foot section of the fin additional strength and ensures a stable hold in the foot compartment without creating pressure points.

When donning a drysuit, the new foot piece not only looks good, but is also functionally impressive: the upper instep area is significantly softer, moulds comfortably to the back of the foot and makes it ea>

WHO IS IT SUITABLE FOR? All-round fin for beginners to advanced divers. Whether holiday diver, club member or dive pro: the Avanti Quattro 4X is suitable for almost all target groups. Thanks to its comfortable foot section and versatile performance characteristics, it is ideal for all types of recreational dives.

Snorkellers with booties also benefit from the easy handling. Restrictions: The fin is too short and not optimised for apnoea divers. It only works for dry diving, however, if the diver tends to have downforce in their legs or works with a foot lead.

The revised cult fin combines proven channel thrust technology with a modernised design and improved materials. Thanks to the optimised side ribs and the more flexible blade, it offers powerful propulsion with reduced effort. The Avanti Quattro 4X is aimed at recreational divers and professionals alike - colourful, functional and versatile. The fin is currently available in several sizes and colour variants for a price of 229 euros.

Performance under water The new Quattro 4X is at its best underwater. From the very first stroke of the fin, you can feel powerful propulsion, smooth water flow without breaking to the left or right and a very controlled blade movement. The fin utilises four distinct channels that form during the leg stroke and efficiently direct the water backwards. We were not able to realistically simulate currents in our test in a German freshwater lake. However, intensive swimming and changes of direction allowed us to understand the reaction behaviour and fatigue very well.

We were particularly impressed by its versatility: classic fin kick, frog kick, helicopter turn, even the reverse kick - everything worked. The latter does require some practice, especially compared to shorter, harder fins from the tech sector. But if you master the technique, you can swim backwards cleanly. The fin blade hardness is at the same level as the Avanti Quattro+, but with finer feedback and slightly improved water tear-off at the side ribs. These have been reinforced and noticeably stabilise the blade.

The 4X also scores points when it comes to handling over water: large bungee straps with grip loops make it easy to put

PRICE/PERFORMANCE With a recommended retail price of €229 , the Avanti Quattro 4X is no bargain, but it is well priced in terms of workmanship, comfort and performance. The durable choice of materials, the flexible bungee system and the well thoughtout design offer clear advantages over cheaper fins. If you are looking for a fin that will last for many years, you are investing in a high-quality, modern all-round solution that will not look out of place in any equipment bag.

With a weight of 2.2 kilograms per pair in size R(egular) and a pressure area of 780 square centimetres, the 4X is in the medium weight range and in the upper area range for fins and is therefore very well balanced.

It is clearly aimed at recreational divers who are looking for a robust, high-performance all-round fin that can cope with changing conditions and types of equipment.

Conclusion The Avanti Quattro 4X fin from Mares is not a revolution, but a consistent further

development. And that's a good thing. If you liked the Quattro+, you will find all the advantages here again, supplemented by more comfort and modern design elements. The optimised foot section of the fin is particularly impressive and makes this piece of equipment a real recommendation for all scuba divers.

3 QUESTIONS FOR MATHIS KAUFMANN, PRODUCT AND PROMOTION MANAGER AT MARES GERMANY TAUCHEN: Why did the "endurance fin burner" Avanti Quattro need a new edition?

Mathis Kaufmann: True to the statement "We don't want to win the race, we want to break the record ...", we wanted to make everything that divers love about the Quattro fin even more powerful, comfortable and contemporary.

What has Mares focussed on in particular during further development?

We have tried to improve the existing features once again to give the product a fresh and modern look and give the fin new features. These include, for example, new, more stable side ribs for better power transmission, a rubber-coated sole on the foot section and a new anatomically shaped bungee with a large

loop.

Who is Mares targeting with this fin?

We do not directly limit the target group. The development of this fin was aimed at divers of all levels of experience - from recreational divers to the demanding everyday life of a diving instructor.

EQUIPMENT ° TEST: AVELO SYSTEM

EASIER DIVING,

SMARTER BUOYANCY CONTROL From the idea of a passionate diver to underwater innovation: the Avelo system promises nothing less than a small revolution in scuba diving. Tessen von Glasow had the opportunity to test the system extensively - and was impressed.

T & F Tessen von Glasow

Diving with Avelo: When the water is blown out of the hydrotank, the mist is created by the high pressure with which the salt water is swirled.

I

've been diving for 35 years. I've tried everything: Diving with "normal" equipment, with double packs and stages, with rebreathers. Somehow I've realised that the trend towards more complex equipment is no longer catching on with me as I get older. I enjoy travelling with lightweight equipment. That's where Avelo comes in.

The engineer and diving instructor Aviad Cahana was also repeatedly asked by his diving students why the equipment was so heavy. For him, this was the impetus to develop a new type of buoyancy control lighter, more stable and easier to use. So Aviad founded "Avelo Labs" (pronounced Awelo) and developed a system based on a physical principle that is also used in submarines: the use of water to control buoyancy. Instead of working with compressible air as in classic jackets, the system uses the surrounding water to regulate buoyancy.

The Avelo system As both the tank and the water inside are virtually incompressible under terrestrial conditions, the buoyancy remains constant throughout the dive - regardless of the ambient pressure. This makes buoyancy control easy during the entire dive. In contrast to conventional buoyancy compensators (BCD), where the gas volume changes due to compression or expansion. With the Avelo system, divers have positive buoyancy at the surface and float comfortably. To descend, the pump is activated for 30 to 60 seconds, filling the hydrotank with water. This reduces the buoyancy. You start to sink. For neutral floating, the diver stops moving. To ascend, it is sufficient to actively swim upwards. As buoyancy increases with breathing gas consumption, more water can be added to the system if necessary to equalise buoyancy. Positive buoyancy is generated at the surface by draining the water from the hydrotank. A separate buoyancy compensator is therefore no longer necessary. Avelo consists of two central components: the hydrotank and a jetpack containing the pump and battery. Compared to conventional equipment, it is between nine and 14 kilo-

grams lighter. A noticeable relief when travelling to and from the dive site and under water. The hydrotank is made of very lightweight material (aluminium-lined pressure tank with full composite coating), has been tested to 1000 bar and is around 5.5 kilograms lighter than a standard steel diving cylinder. The tank is available in eight or ten litre sizes and has a 300 bar DIN valve.

Double valves are also possible. The actual breathing gas bladder is located in the tank.

The bladder is made of an elastomer specially developed for breathing air and higher oxygen mixtures. The jetpack contains a hydraulic pump that can pump around one litre of water per minute - i.e. around one kilogram of downforce - into the tank. The integrated battery lasts for around eight pumping cycles, or around eight minutes of pumping time. The backplate is made of lightweight aluminium, which makes the overall system even lighter.

fies that the hydrotank is visually inspected annually. The breathing gas bladder is also always replaced. As with conventional diving cylinders, a pressure test is scheduled every five years. The Avelo system is certified for nitrox mixtures containing up to 40 per cent oxygen.

Two dive computer manufacturers now offer special "Avelo modes" (Scubapro and Shearwater) for dive monitoring. A special feature is the new type of level indicator.

Instead of relying solely on the display of the absolute value of the pressure - which can lead to misinterpretations with compressible gas bubbles - the Avelo mode takes into account the product of absolute pressure and bubble volume. Consumption is indicated as a percentage, providing a realistic estimate of the remaining breathing gas supply at all times. Regardless of how much the bladder is currently compressed. But of course there is also a backup in the form of a table so that you can dive with Avelo even without a computer.

Above: the Avelo mode, integrated into the Scubapro Galileo dive computer. Below: Avelo table for manual calculation.

Some people ask themselves the question of reliability. The first thing that comes to mind is your own experience of using inflatable buoyancy compensators (BCDs).

Malfunctions of such systems can lead to abrupt and dangerous changes in buoyancy. A blocked inflator hose can cause a diver to shoot uncontrollably to the surface within a few seconds - with potentially serious consequences. This is not the case with the Avelo system. The diver remains in control and has sufficient time to recognise a potentially critical situation and end the dive safely. If, for example, the pump, switch or battery fails and no water fills the hydrotank, the buoyancy only changes gradually - namely when the diver becomes a little lighter due to gas consumption. Even then, the change in buoyancy is very small and amounts to no more than about one kilogramme. Even if the purge valve does not work and no water is drained from the hydrotank, the buoyancy remains stable until the diver becomes lighter due to further gas consumption. In this case, water can be added in a controlled manner. If the pump unintentionally continues to supply water, it can be drained again manually.

The change in buoyancy is so slow that no critical negative buoyancy occurs. The Ave-

The Avelo course In spring 2025, I was able to test the system for myself on holiday on the Caribbean island of Bonaire with "Dive Friends Bonaire". I completed the Recreational Avelo Diver (RAD) course, which is divided into an eLearning part and a practical day with theory lessons and two dives.

The eLearning section is well organised and structured. It describes the individual components in detail and explains the basic functionality of the Avelo system. The calculation of the amount of ballast lead still required is also included. I had completed and passed this part from home before my holiday. At the end of the two-hour course, you have to take a final test.

"Dive Friends Bonaire" Dive Friends Bonaire was founded in 2002 and today operates seven dive centres and

four retail outlets on the island. With a team of over 60 employees, it is one of the largest diving centres on Bonaire. The Managing Director is Dutchman David Rietveld.

Dive Friends Bonaire was the first official Avelo dive centre in the world to start using the innovative system in 2023. There are currently five Avelo instructors and a specialised technician on duty. The dive centre is also actively involved in testing and further developing the Avelo system.

The classroom course was great. My instructor Duncan Versteegh (49), a Dutch diving instructor with over 20 years of experience who has lived on Bonaire for five years, gave me a thorough and practical introduction to the technology. He began with a detailed explanation of the system, the components and how they work together. This was something completely different from the theory - holding the components in your hand and "experiencing" them demonstrates the simplicity.

After about two hours, it was time for the diving practice. Before the first dive, you have to pass a fitness test: You have to walk about 500 metres with all your equipment on and swim the same distance with all your equipment on the surface. Before you start swimming, your buoyancy is checked. In contrast to a normal diving device, you are immersed a little deeper in an upright swimming position, so depending on the conditions, the use of a snorkel is recommended, as specified by Avelo.

Then we go underwater. Various depth changes are carried out here to familiarise yourself with the reactions of the system.

Back in the shallow area, the buoy mounted on the jetpack is used. This is also used on the surface. After a diving break, the second dive began. In addition to refining buoyancy control, two safety exercises are integrated here: You have to take the diving equipment off your back while floating un-

is increased by draining water from the tank. This is done by simply opening the valve. Conversely, water can be pumped in if the breathing gas has changed the buoyancy due to consumption. The combination of non-compressible water and a constant bubble size in the tank results in great buoyancy stability, which makes diving safer and more comfortable.

derwater and put it back on without losing your buoyancy.

The last exercise on the programme before surfacing is a partner rescue. Under water, the buddy reports shortness of breath and you have to bring them safely to the surface using your own second regulator or octopus - using the Avelo system.

The exercises were explained in detail

by Duncan on land and demonstrated underwater before I had to show them. Duncan is a great diving instructor. In addition to the problem-free teaching, the fun was never neglected and the day flew by.

After the course, I was able to test the Avelo system further in the following days, both with Duncan and independently on several dives. After calculating the required downforce weight (for me, at 1.87 metres tall with a body weight of 80 kilos and a five-millimetre wetsuit, it was around two kilos of lead, later only one kilo), the system was adjusted at the surface. The descent works by pumping: after about a minute you are neutrally buoyant, and the descent begins when you exhale. "Changing depth" can be controlled almost exclusively by breathing and minimising the use of fins - a new, calm diving experience. The buoyancy

Buoy riding is used to stabilise after a dive when you are still waiting at the surface.

Conclusion The Avelo system has convinced me. It is light, stable, well thought-out and gives you a completely new diving experience. What certainly helps is that you don't have to change practically anything in your dive planning. The length of the dives remains the same. You just need a little less breathing gas. For me, this has meant that instead of my "normal" 80 cft tank (about 11.3 litres), I can manage with the ten-litre hydrotank under otherwise identical conditions. I got on very well with Avelo on my very first dive. It really is child's play to switch over. If you learn to dive with Avelo, it should be even easier. All in all, I can say that it's hard to believe that you don't have to constantly re-tare as with the conventional system, but can change the depth >

EQUIPMENT ° TEST: AVELO SYSTEM at any time after the descent with the lung tare and a few fin strokes. And when you have used up half of the breathing gas supply, you can make a small correction to the buoyancy with the pump and continue undisturbed. It is also fascinating that there are no sudden reactions from the buoyancy system, but that all adjustments are always very "smooth". Regarding my training with the Avelo system, I would like to say once again that the entire course was a real pleasure. I would very much like to continue diving with Avelo in Germany. Unfortuna-

tely, however, there is still no centre here that offers the Avelo system. Of course, as with every device, there are ideas for improvement, for example in the carrying unit (more D-rings, a little more volume for thicker suits or drysuits). But the basic idea is excellently realised, the technology is sophisticated and operation is intuitive.

And as the Avelo creator Aviad explained, a number of optimisations and further developments are about to be released, so there are still exciting things to come. Avelo is ideal for warm water regions. But accor-

ding to Aviad, it can also be used in colder waters with dry suits - although I have yet to test it in cold water. I'm looking forward to seeing how the system develops. Anyone who has the opportunity to test the Avelo system should definitely take it. It's an experience that will change diving forever.

"AVELO IS LIKE FLYING UNDER WATER" INTERVIEW WITH AVIAD CAHANA, THE INVENTOR OF AVELO

Aviad, tell us something about yourself first.

I am 48 years old and an engineer with two degrees (in chemistry and environmental technology). I was born in Israel. I learnt to dive in 1998 as a CMAS and BSAC instructor in the Red Sea. I am currently a PADI, SSI and NAUI instructor.

Today, diving is a passion for me that I can combine with technology. For me, training in the Avelo system means giving people the feeling of flying underwater. That is exactly what I want to convey.

When did you have the first idea for the Avelo system?

After several questions from diving students, the final trigger was a dive off Maui. I had to walk a long and tiring way before entering the water, heavily laden with the usual equipment. During the entire dive, I asked myself: Couldn't this be

easier? And how can it be done?

Initially, I experimented with a pneumatic system that utilised cylinder pressure. After a year, however, I discarded this idea and instead developed a hydraulic system with an electrically operated pump. The first functional prototype was ready in 2019.

During the coronavirus pandemic, I pushed ahead with development intensively for another three years.

In 2023, we were then able to officially launch Avelo in the Caribbean at Dive Friends Bonaire and certify the first divers.

How is the Avelo system currently spreading worldwide?

Avelo is currently available at selected diving centres, primarily in the USA and on Bonaire, but also in Canada, Spain and Australia. A brand new addition is Asia, specifically Malaysia. Cozumel in Mexico is also planned for 2025. In Europe, the focus is currently only on Spain. No other locations are currently being planned. However, we also see strong potential in the Middle East on the Red Sea - in Jordan and Saudi Arabia, among other places.

Where is Avelo's technical development heading?

We are working on several exciting concepts: larger tanks, possible double tank systems and the operation of lamps or heating systems via the Avelo battery are all conceivable. An underwater communication solution is also a topic. One particularly ambitious project is an open system with an automatically adjusted breathing gas mixture that utilises sidemount cylinders.

The Avelo pump acts as a compressor. This is currently being produced in France. A brand new development is the intensification of the cooperation with Shearwater. The new Shearwater jetpack has integrated gas pressure monitoring and can be connected to Shearwater dive computers in Avelo mode. This enables precise tracking of gas consumption, predictive buoyancy control and comprehensive performance analysis - all in real time. A new, significantly lighter tank is already available.

And what about the price?

Of course the price has to fall in the long term, we realise that. But the Avelo system will always maintain a certain price level - quality and innovation have their value.

Are there any plans for training with Avelo for beginners?

Yes, we are currently in a pilot phase for beginner training with Avelo. Our experience so far has been very positive: beginners in particular often find it easier to learn to buoyancy control with Avelo. Many of them master lung buoyancy control after just a few dives - faster and better than with conventional BCD systems.

What is particularly important to you personally about Avelo?

For us, the human spirit, i.e. the human spirit of discovery, is at the centre. Avelo is not just technology.

We see ourselves first and foremost as a training organisation. We work together with many companies that have great ideas on how Avelo can be used outside of scuba diving. One thing is clear: we are not changing physics - we are simply using it better. And most importantly, you have to have dived Avelo yourself to understand what it really means.

CITIZEN SCIENCE UNDER WATER DIVERS HELP TO MEASURE CLIMATE CHANGE

The Mediterranean is getting warmer with dramatic consequences. According to the EU's Copernicus climate service, 2024 was the warmest year since weather records began.

T

To ensure accuracy, BlueDOT has installed high-precision temperature sensors at reference dive sites in Spain, Heligoland and Malta. These make it possible to calibrate the measured values of the various dive computers. "With an estimated six million active divers worldwide, this method has enormous potential," says project manager Dr Christophe Galerne. The data complements existing measurement systems such as satellite observations and autonomous Argo measuring buoys - and, above all, closes an important gap: to date, most of the data comes from the summer months, when most people are in the water.

BlueDOT is therefore calling for dives in spring, autumn and winter to be documented in order to gain a more complete picture of seasonal changes. The project, launched in December 2024 and initially scheduled to run for 18 months, is funded by the German Federal Ministry of Research, Technology and Space and is part of the UN Decade of the Ocean. Those who take part not only contribute to research, but also make a personal contribution to measuring the "pulse" of our oceans - dive by dive.

Elk antler coral

MORE DIVERSITY FOR STRONG CORALS

An international team of researchers including the Alfred Wegener Institute is calling for a reform of international laws to facilitate the exchange of corals between countries. The aim is to increase the genetic diversity of corals and strengthen their resilience to climate change. Current regulations such as CITES and the Nagoya Protocol make it difficult to protect reefs across borders. The scientists are in favour of new rules, regional coral biobanks and faster cooperation in order to build up resilient coral populations with the help of targeted cross-breeding. Initial successes have already been achieved with elkhorn corals that originate from parents in different countries and have been replanted in the reef. In view of the rapid threat posed by rising sea temperatures, the researchers warn that without rapid reforms, irreversible damage - and the loss of many reefs worldwide - is imminent.

heMediterranean is getting warmer - and that has consequences. According to the EU's Copernicus climate service, 2024 was the warmest year since weather records began. Rising water temperatures not only have an impact on extreme weather events such as storms and flooding, but also on biodiversity and marine ecosystems. This is where the BlueDOT citizen science project, coordinated by MARUM - Centre for Marine Environmental Sciences at the University of Bremen, comes in. The idea: scuba divers from all over the world make their dive profiles available, which contain temperature data from the upper 40 metres of water. These are uploaded via the Divelogs portal. This creates large-scale and temporally diverse data sets that help to document marine heatwaves and better understand the effects of climate change on the oceans.

ARCTIC VIRUSES IN AN ANNUAL RHYTHM

A new multi-year study by the GEOMAR Helmholtz Centre shows that the viruses in the cold waters of the Arctic vary greatly over the course of the year - both in terms of their number and their composition. surprisingly, the researchers found that many virus species in the Arctic are very similar to those in the Antarctic Southern Ocean, even though the two regions are far apart. Particularly striking is the sharp increase in virus numbers in late summer, when there can be up to 30 viruses per single bacterium, while in winter the number of viruses is roughly the same as that of bacteria. Viruses specifically control the growth of their bacterial hosts and thus influence important ecological processes and the flow of nutrients and energy in the oceans. As viruses react very sensitively to environmental changes such as temperature, salinity or ice cover, climate change could significantly disrupt the fragile microbial balance in the polar regions. The scientists therefore see viruses as important early indicators for recognising changes and risks in these sensitive ecosystems at an early stage.

Research divers have found 16 English cannons off Helgoland in the summer and documented them.

16 ENGLISH CANNONS OFF HELIGOLAND

Research divers from the company Submaris discovered a total of 16 British cannons off Heligoland this summer. Seven cannons were already recovered here in the 1990s. The cannons are scattered on the stony ground between the main island and the dune. They are probably 12-pounder cannons from around 1800, clearly of British origin, recognisable by details such as the "Blomefield ring". The Blomefield design, developed from 1787, is characterised by a stabilising ring on the pommel, which secures the recoil rope ("brooktau") and thus makes the cannon more flexible and safer to use on board. The cannons were systematically measured, photographed and documented with 3D models.

They are not from the HMS Explosion, which sank off Heligoland in 1807, as had long been assumed. Historical sources and the wide distribution of the guns rule out a wreck as the cause of the discovery. It is more likely that the British scuttled the cannons off the island when they withdrew in 1890 - obsolete material that was not taken with them. Heligoland was a British crown colony until 1890 and an important naval base. Today, the cannons are silent witnesses to this eventful history.

Our expert For their study, the researchers analysed millions of DNA sequences from Arctic water samples and were able to identify viral communities and assign them to their preferred hosts - mostly bacteria. The finely balanced microbial equilibrium could be shaken by climate change, they warn.

Dr Florian Huber reports here every month on the latest news from the scientific underwater world. He himself is an underwater archaeologist and research diver (florian-huber.info).

GIANT WAVES IN THE NORTH SEA

Research results from the North Sea provide surprising insights into the formation of so-called "rogue waves" - extremely high, suddenly occurring waves. A long-term analysis of wave data from the Ekofisk oil platform disproves a previously widespread theory: according to this theory, small differences in wave height and distance should become increasingly stronger due to non-linear effects and thus form large rogue waves - a process known as "modulation instability". However, the new data show that this effect hardly plays a role in the open sea. Instead, giant waves are mainly created when waves from different directions meet and their energy adds up, as well as by asymmetrically steep wave crests with shallow troughs that can make individual waves significantly higher. These findings enable improved early warning thanks to an AI-supported forecasting model that is already being used by NOAA and Chevron.

Giant waves seem to come out of nowhere and can become extremely large.

he route covers more than 460 kilometres through the open sea, passing spectacular dive sites in every atoll. A project that not only pushes sporting boundaries, but is also intended to draw attention to the protection of the oceans. The project was originally planned in two phases: The first was to start in February 2025 with a world record attempt for the longest DPV (Diver Propulsion Vehicle/Scooter) dive in the Greater Malé region. However, due to technical challenges, the team decided to combine both phases into a single, ground-breaking expedition in spring 2026.

"Pushing boundaries has always been something that drives me. It is in these moments that we realise what our spirit is truly capable of. Across Maldives will be the biggest challenge of my life - and also a very personal one. One of my father's last sentences before he died was: "I wouldn't be surprised if you dived across the Maldives". I dedicate this expedition to him," says Shafraz (Shaff) Naeem.

Two world record attempts Shaff will complete two dives per day, each lasting up to three hours. Using a DPV (scooter), he will cover eight to ten kilometres per dive and attempt to set two world records: the longest distance covered with a DPV in a single dive in open water and the longest distance covered with a DPV within a month in open water.

DIVING.COM

In spring 2026, a unique diving expedition will take place with "Across Maldives". The experienced Maldivian diver Shafraz (Shaff) Naeem will dive across the entire island archipelago with the support of his team - from the northernmost point of the Maldives to the southernmost tip.

Science and Community engagement In addition to the record attempts, Shaff will be accompanied by a team of local and international divers, scientists and marine conservationists. Important data will be collected along the route, for example on the health of the coral reefs, underwater topography, water temperature and environmental DNA (eDNA). All data will be made publicly accessible. Educational workshops and information events on the islands are

also intended to raise awareness of marine conservation and climate change.

Nationwide support and international attention The Maldives National Defence Force (MNDF) is actively involved in route planning. The Maldives Marketing and Public Relations Corporation (MMPRC) supports the global communication. The entire expedition will be documented on film.

What are currently the biggest threats to the Maldives' marine ecosystems?

Climate change, overfishing and careless tourism - they cause coral bleaching, destroy reefs and jeopardise habitats.

What data should be collected during the expedition? And why is it important?

Water temperatures, coral bleaching, sightings of marine life - this information helps to recognise changes and develop protective measures.

How can Across Maldives contribute to the protection of coral reefs?

I want to show what goes on under the surface of the water and raise awareness.

Because we only protect what we know and love.

What impact will the project have on local communities?

I hope to inspire young Maldivians and get them excited about the sea, diving and ocean conservation.

Shaff's team tested the equipment (scooter, rebreather) during several dives on site at the beginning of this year.

HEY DOC, DOES THIS MAKE ME FIT TO DIVE? In this column, we answer readers' questions about fitness to dive.

This part is about bronchial asthma.

Hey Doc, my 16-year-old son has allergic bronchial asthma and would like to take his diving licence on his next family holiday.

Allergy-related symptoms occur in spring.

At this time he also uses an antihistamine and an asthma spray. Is there anything standing in the way of his fitness to dive and a planned diving course?

DIVING 10°2025

Respiratory diseases such as bronchial asthma are among the most common chronic diseases in the western world, alongside cardiovascular and metabolic diseases.

Bronchial asthma is a chronic inflammatory disease of the airways. It is characterised by a reversible narrowing of the bronchial tubes (obstruction) and hypersensitivity of

the airways (bronchial hyperresponsiveness). The symptoms can vary greatly: Some sufferers only experience occasional coughing or difficulty clearing their throat.

Others experience acute attacks with wheezing, chest tightness and shortness of breath - in extreme cases with life-threatening consequences. Many cases are caused by alDIVING.COM

OUR EXPERT

lergic asthma - environmental factors and allergens such as pollen or house dust play a major role here.

According to the WHO, around 235 million people worldwide are affected. In childhood, boys are more likely to develop the disease, in adulthood it is mainly women.

Bronchial asthma and diving Bronchial asthma is a respiratory disease characterised by a permanent inflammation of the airways - with a permanent readiness to react hypersensitively to certain stimuli in the inhaled air and thus the environment (bronchial hyperresponsiveness). As a result, the airways swell and thick mucus obstructs the airways, which can ultimately lead to the airway obstruction described above and thus to breathlessness.

When diving, we breathe in very dry, cold air from the diving equipment. This air can provoke an asthma attack in asthmatics, especially during physical exertion under water.

Furthermore, a high flow velocity, as occurs during increased exertion under water or during deep dives, can cause an obstruction in the small airways. A central problem here is so-called "air trapping": The constricted airways do not allow all of the air to be exhaled again when surfacing (decompression phase). The trapped air expands during the ascent - there is a risk of barotrauma, i.e. overstretching and, in the worst case, a rupture in the lung tissue (pneumothorax).

Specialist and control The good news for asthmatics is that they are not fundamentally excluded from diving. There is no absolute contraindication to the granting of a diving licence.

The decision for or against fitness to dive depends on the type and control of the asthma. If asthma is well controlled, i.e. if there are no symptoms, lung function is stable and regular medical care is provided, diving is possible. However, an individual risk assessment must be carried out, ideally by a lung specialist with experience in diving medicine. People who suffered from asthma as a child but are now symptom-free and have normal lung function values may also be fit to dive.

Here too, a medical examination is required to rule out permanent bronchial hypersensitivity.

ness for diving must be assessed in a differentiated manner, taking into account the individual type and severity of the asthma.

Individual asthma control and regular medical care are crucial. With good preparation and a clear awareness of the risks, safe diving is also possible with asthma.

WHEN IS DIVING POSSIBLE AND WHEN IS IT NOT? The German Society for Diving and Hyperbaric Medicine (GTÜM) recommends the following categorisation: Diving is possible if: ■ the asthma is fully controlled, i.e. there are no acute symptoms.

■ regular medication (e.g. with metered dose inhalers or powder inhalers).

■ the peak flow value, measured with a peak flow meter, is above 80 %of the personal best value.

■ lung function is normal (detectable by spirometry).

■ there are no signs of exercise- or cold-induced asthma.

Diving is not advisable if: ■ the asthma is only partially controlled.

■ there have been asthma attacks caused by exercise or cold in the past.

■ medication is regularly required for emergency treatment.

Diving is absolutely contraindicated if: ■ the asthma is not controlled.

■ I recently had an asthma attack.

■ if the lungs are already over-inflated (emphysema).

Dr Dr Philipp Stahl, deputy medical director at aqua med, will be leading this column and is looking forward to answering readers' questions and providing well-founded insights­. Send us your questions to: redaktion@tauchen.de, keyword "Hey Doc".

What should asthmatics consider before diving?

■ Carry out a peak flow measurement: Immediately before the dive, you should check whether the airways are clear. Values below 80 % of the best value are an alarm signal.

■ Keep inhalation medication ready: only with prior medical authorisation! Never take medication spontaneously before the dive without prior consultation.

■ Do not dive if you have a respiratory infection: even a simple cough or bronchitis can greatly increase the risk.

■ Watchout for chesty coughs: these can be an early warning sign. If you are unsure, the dive should be cancelled or not started at all.

Conclusion Nowadays, asthmatics are not generally excluded from diving, i.e. there is no absolute contraindication. FitDIVING.COM

Algae are fascinatingly diverse. They can be categorised into three large groups according to their pigment composition and cell structure: GREEN ALGAE (CHLOROPHYTA)

▶ Mostly bright green due to chlorophyll ▶ Often in shallow, light-rich zones ▶ Example species: Caulerpa, Halimeda, Ulva ▶ Often stringy, leafy or calcareous BROWN ALGAE (PHAEOPHYTA)

▶ olive to brownish due to fucoxanthin ▶ typical in cooler, nutrient-rich waters ▶ Example: Kelp (Laminaria), Padina, Dictyota ▶ Often leaf-like or ribbon-like, with adhesive organ (rhizoid) RED ALGAE (RHODOPHYTA)

▶ Red to purple due to phycobilins ▶ Often in deeper zones or as crustose algae ▶ Example: Jania, Corallina, Gelidium ▶ Some species can store lime and contribute to reef growth Tip: Often several groups of algae grow in one spot - the colour spectrum and structure help with the rough classification.

Marine flowering plants Marine flowering plants belong to the higher plants. They are clearly structured and have real roots with which they anchor themselves in the soil. They also have shoot axes that stabilise the plant as well as vascular vessels to transport water and nutrients efficiently. Even if you can hardly see it under water: They bloom, inconspicuously and adapted to the current or pollination conditions of the sea. Wellknown representatives such as seagrasses (Posidonia, Thalassia, Zostera) form extensive underwater meadows that serve as nurseries for many creatures and fulfil important functions in their ecosystems as oxygen producers andCO2 reservoirs.

2) Posidonia oceanica - Seagrass meadows of this species are ecologically very important. They produce oxygen, bindCO2, stabilise the seabed and provide a habitat.

3) The limb-like green algae Halimeda deposits calcium carbonate and thus contributes to reef formation. When it dies, its parts disintegrate into fine white sand.

4) The inconspicuous calcareous red algae Corallina also stores lime and acts as a natural reef

EXPERTS ° APNOEA

ROCK STAR SKANDALOPETRA Being pulled into the depths clinging to a rock?

Not a thriller scene, but rudimentary apnoea diving.

T Nik Linder

D

o you remember the reality series "The Simple Life"? Back then, Paris Hilton and Nicole Richie, who were used to luxury and glamour, had to shovel manure on the farm. It was amusing and at the same time conveyed a sense of longing: back to a time when things were simpler - without social media, smartphones and permanent online mode. And it is precisely this "simple can be great" feeling that can also be found in the story of Skandalopetra. It's often the simple ideas that turn out to be brilliant.

Pure minimalism: Apnoea diving with stone Freediving is the epitome of reduction.

Even if the equipment used today is hightech, it is the person, not the material, that is decisive. Hardly any other discipline epitomises this idea as much as scuba diving.

What counts here is: as little as possible, as deep as possible. Skandalopetra is considered the cradle of apnoea. in 1913, Greek fisherman Haggi Stathi Chantzis dived to a depth of 83 metres to retrieve the lost anchor of the Italian navy ship "Regina Margherita" - without any special fitness equipment, just a stone to pull him down into the depths. This stone was connected to the surface by a rope so that it could be retrieved after the dive. "Skandalo" means trigger, and "Petra" means stone. That's all you need. No wetsuit, no mask, no fins - just a person, a stone and the deep. >

At depth, the speed continues to increase as the buoyancy of the suit and lungs disappear.

EXPERTS ° APNOEA

A special kind of team sport: While the weight of the stone takes over the descent/descent, it is the muscle power of the buddy on the surface that is used to bring the diver and stone back up to the surface.

DIVING 10°2025

DIVING.COM

Teamwork with clear roles Apnoea diving is never a solo sport safety comes first. But Skandalopetra is the only discipline with a fixed buddy system: one dives, one pulls. Then it's time to switch. This simplicity makes the discipline particularly archaic and yet highly technical. The current world record is held by German mine diver Andreas Güldner with an incredible 112 metres - using only one stone.

The special challenge The biggest obstacle is not the weight of the stone, but equalising the pressure. If you dive head first, you have to react particularly quickly because the speed of descent increases with depth. You can stand upright on the stone to make it easier to equalise the pressure. But the accelerated descent remains a challenge.

The weight of the stone (eight to 12 kilograms) remains constant. But as the water depth increases, the lungs compress - and you fall faster. Braking is only possible to a limited extent, for example by spreading your legs to increase the water resistance. If pressure equalisation is not successful, the stone must be released immediately to avoid injury.

But the biggest test is mental: without fins, you are completely dependent on your buddy on the surface to pull you back up quickly. In an emergency, you can work your way up the rope, similar to the free immersion discipline. But the feeling of dependency remains. For the partner on the surface, on the other hand, pulling is a challenging workout, especially for the first few metres.

The German championship: from scepticism to enthusiasm At the first German championship in Hemmoor, the initial reluctance quiDIVING.COM

ckly disappeared. Cheered on loudly, the buddies pulled their partners back to the surface, while the divers enjoyed the feeling of descending to the depths and back up again almost effortlessly. Compared to classic apnoea diving, there is no need for the strenuous struggle against buoyancy - an experience that many found surprisingly liberating.

These Skandalopetra stones weigh twelve kilograms each and come from Greece. Importing them was cheaper than having them made in Germany.

Before the competition, the rope is officially measured. Lawyer and competition judge Dr Klaus Wagner monitors the correct execution.

Premiere with neoprene and mask The first Skandalopetra weekend in Germany took place at the beginning of June. Unlike classic Skandalopetra dives, wetsuits and masks were permitted at this competition in Hemmoor - the water was simply too cold.

Eight male and two female athletes took part and the depth was limited to 40 metres. The weekend offered breathing and relaxation sessions, a scandalopetra workshop for beginners and numerous photo sessions. Through repeated training descents, the participants felt their way towards their "announced performance" - the depth they wanted to reach on the day of the competition. Under the guidance of Dr Klaus Wagner, former AIDA President, and secured by record-breaking diver Andreas Pap with his scooter, the competition dives took place. The youngest participant was an elevenyear-old boy who reached 15 metres together with his father. The overall winners Ünal and Horry dived 80 metres together. Monika and Katharina reached 40 metres.

FLASH TRIGGER FOR UPGRADING

The "Fotocore flash trigger" (with CR2032 battery) is mounted on the hot shoe and "installed" on the outside via an M16 feed-through. There, the light signal generates the flash triggering of fibre optic flashes (two connections). It is compatible with all cameras that have a flash connection and with all housings that have an M16 connection. The retail price is 199 euros.

FREI'S PHOTO CORNER

The new Nauticam NA CV1 underwater housing for the Canon PowerShot V1 is now available from PanOceanPhoto for 1700 euros.

The milled aluminium, hard anodised housing is waterproof to 100 metres and offers ergonomic operation with two­step release levers.

It has a vacuum and leak warning system, an N50 port with 3.5" dome port and is compatible with WWL C and CMC macro converters.

The scope of delivery includes O-ring, dome port, tools and transport case.

FLASH/CONTINUOUS LIGHT COMBINATION

The AOI UCS Q1i underwater flash is now available from PanOceanPhoto for €459 . It combines the advantages of the Q1 series with the new AOI InTeLi mode, which offers precise TTL exposure (including HSS) with Sony and OM system cameras. A special i-Macro mode provides optimised light for close-ups. With a guide number of 22, 85° beam angle, 700 lumens continuous light and a flash charging time of 0.85 s, it is powerful and versatile. The compact, robust housing is waterproof up to 60 metres, supports around 1500 full flashes with two batteries and is supplied with a diffuser, O-ring set and accessories.

THE OMINOUS EQUIVALENCE the word "equivalence" can be translated as "equivalence". This term is usually used for focal lengths that are intended for smaller image sensors than the full-frame format. Let's assume that you own a 60 mm macro lens for the MFT system from OM Solution or Panasonic, then the 60 mm macro corresponds to a focal length of 120 mm equivalent to small format. This is because image sensors in the MFT system have a crop factor of 2.0 - because their sensor diagonal is only half as long as that of the 35 mm format. Whereby 35 mm format and full format mean the same thing, i.e. an image sensor with a format of 24 mm by 36 mm. Only with the equivalence comparison or the crop factor is it possible to compare the focal length of a lens on a small image sensor with lenses from the 35 mm sector. Example: The Sony RX 100 MK VII compact camera has a zoom with a focal length of 9 to 72 mm. If you now want to know what angle of view the varifocal lens has, you first have to determine the sensor format. It is a 1-inch image sensor with 13.2 mm by 8.8 mm.

This results in a crop factor of 2.7, as the sensor diagonal is 2.7 times that of the 35 mm format. The zoom focal length of the compact camera is therefore multiplied by 2.7 - which corresponds to a rounded 35 mm zoom equivalent of 24 to 200 mm. This results in an angle of view of 84° to 12°. You can then use this in practice and plan your motifs accordingly. Because the camera manufacturers know that users are not always very familiar with such calculations and comparisons, the equivalent focal lengths and equivalent picture angles are normally included in the operating instructions.

FOCUS ° SEA & SEA LX LAMPS

AND THERE WAS LIGHT!

The new LX lamp series from the Japanese UW photo specialist Sea & Sea praises itself as the leader in the video lamp market. Is there any truth in this? And if so, what characterises these stylish little lights?

T & F Timo Dersch

T

he fact is that the construction of underwater video lamps is no easy task for manufacturers. On the one hand, the development of LEDs is progressing at breakneck speed. Once a lamp has been completed and launched on the market, there are already new light diodes from the Far East that are brighter or more energy-efficient or whatever. In addition, you have to deal with no-name suppliers from China as direct competitors. This is because their lamps can also provide a lot of light and cost a fraction of the price.

However, high-quality video lamps differ in many details that the layman may not immediately recognise. Firstly, there are the control electronics. This ensures that the light output does not decrease when the battery level drops, but that the lamp constantly emits the desired amount of light. At the same time, it protects the batteries from deep discharge. Otherwise they can quickly become scrap. With Sea & Sea, these control electronics even allow the lamps to be set to the exact percentage - from one to 100 per cent - in addition to four different light output levels. This is a novelty >

FOCUS ° SEA & SEA LX LAMPS The lamps in the LX series are available in stylish black and white. The grooves on the lamp head ensure improved heat dissipation. The batteries and lamp heads can be easily replaced.

Practical: The battery does not need to be removed for the charging process. Simply unscrew the cover of the charging socket and attach the charger - done.

The screenshots from the video test clearly show the softly lit image and the natural shadows. Filmed with an Insta360 AcePro 2, you can watch the whole clip on TAUCHEN Instagram.

TECHNICAL DATA: Luminous intensity: LX4000: 3860lm (flood) / 1500lm (spot) LX2400: 1200lm (flood) / 1500lm (spot) LX1200: 2400lm (flood) / 1500lm (spot) Beam angle: under water 100° (flood) / 30° (spot ) Colour temperature: 5500 K (flood) / 6500 K (spot) Colour rendering index: RA90 (flood) / RA70 (spot) Burning time highest level: 30 minutes (flood) / 90 minutes (spot ) Setting options: 4 levels (25% increments) / 100 levels (1% increments) Flash sensor: yes Remote control: optionally available Display: Colour LCD panel Battery: 3400 mAh / 7.4V Li-ion battery Charging time: 2.5 hours Housing material: Aluminium Depth certification: 100 m Scope of delivery: battery, charger, pistol grip, ball head adapter, YS adapter, GoPRO adapter, Loc-Line adapter, cover for charging socket, charging connection, wrist lanyard, fastening screw, Allen key, O-ring grease, O-ring tool

and unique selling point. The setting is shown on a bright and easy-to-read segment display. Particularly practical: in addition to the currently selected brightness setting, the remaining battery life at the selected level is always displayed. We liked this in the test, as it allows you to divide up your battery power within one or more dives and not literally poke around in the dark.

Uniform light, natural shadows There are also the LEDs used. There are extreme differences in the quality of the light they emit. And this is also the crucial point that makes the new Far East torches truly unique. So-called COB LEDs have been installed in a "donut shape". COB stands for "Chip on Board". This type of diode is particularly known for its even light distribution. This creates a uniform wide-angle flood without visible steps in brightness within the light cone. The donut also prevents the so-called multiple shadows caused by many LEDs being switched on at the same time. It's clear: if the light is emit-

ted from different directions, there are also different shadows, which quickly creates an unnatural effect in the image. However, as the light shines through a large area in the COB, a clear, unambiguous shadow is created, just like the one that would be cast by sunlight, which emphasises the illuminated object clearly and naturally. It works.

The result is visible.

Spot on!

In addition to the flood function, the lamp also offers a spotlight function. The single LED in the centre of the donut hole is responsible for this. Why do you need this?

For example, if you want to use your lights as diving lights to search for objects or illuminate surroundings, but don't want to waste your battery power on video lighting.

This saves juice. The spotlight is also suitable as a focus light for photographers. Speaking of which: As photographers, we were particularly pleased with the light sensor on board during the test. It recognises when a flash is triggered and then switches

off the lights (whether in spot or flood mode) for a second to avoid any annoying extra brightness in the image. That is practical.

If in doubt, two batteries Anyone who dives a lot at the highest level should consider ordering a second battery.

This is because the battery can run low during a repetitive dive if it has not been charged in between. There's no other way, because the lamps have a very compact pack size, which also affects the size of the battery. It is particularly great that the battery can be charged in two ways. Directly on the charger, but also in the lamp. In the test, this proved to be practical, as the batteries did not have to be removed after the dive, but the torch could simply remain on the camera arm and be plugged in. A cool thing.

It should also be mentioned that there are three variants: the 1200, 2400 and 4000 lumen versions. So the higher the price, the brighter the light. Also on offer: a wide range of adapter accessories. A ball head adap-

ter, a GoPro adapter, a YS adapter and a LocLine adapter are included as standard.

The right adapter is therefore included for every type of housing and arm.

Conclusion: With the LX lamp series, the customer receives outstanding light quality at an acceptable price. Whether you can really take the self-proclaimed top spot among video lamps depends, as is so often the case, largely on the requirements of the user. Many video professionals will probably continue to rely on Keldan, if only because of the larger batteries. Compared to the other manufacturers, however, the Japanese have won the race for the time being. We give the products a clear purchase recommendation for all hobby film-makers, but also for ambitious underwater videographers. In any case, we recommend the 4000 lumen version.

Fun fact: If you want to film shark dives with food, the (albeit very stylish) white version of the lights is not recommended the black ones are less likely to be mistaken for a piece of fish.

The front view clearly shows the COB LED for the wide-angle flood and the single LED in the centre, which is responsible for the spot beam. The graphic below clearly illustrates the advantage of the natural shadows created by the COB LED.
