Dual frequency
sonar from Tritech
Tritech International Limited recently announced the release of the Gemini 1200ik Dual Frequency sonar, the latest addition to the ever popular Gemini range. The multibeam imaging sonar offers two operational frequencies with the ability to switch between low and high frequency dependant on the user’s requirement. The 720kHz low frequency setting is designed for target identification and obstacle avoidance at long range, whilst the 1200kHz high frequency setting offers extremely detailed multibeam images, ideal for inspection at close range. Switching frequencies can be set to automatically switch over at a specific range or done manually. Unique to the Gemini 1200ik is the ability to maintain a 120 degree field of view across both frequencies ensuring the target remains in view when operating at high frequency and at short range. Tritech’s Gemini range is used globally in a wide mix of applications from oil and gas operations to search and recovery and shark detection. With a depth rating of 350m, the 1200ik marks the next generation of sonars from Tritech which are ready to take on tougher environments and more challenging operations. Significant engineering development has resulted in this latest Gemini imaging sonar offering a 2.4mm range resolution, as well as an effective angular resolution. www.tritech.co.uk
