SEA BEAM 3012 - MULTIBEAM SONAR 12 kHz 205 individual beams 140째 swath width up to 31 km seafloor coverage 11000 m depth performance realtime Water Column Imaging option realtime motion compensation Windows 2000/XP or UNIX/LINUX shallow water focussing

SEA BEAM 3012 Multibeam Echosounder collects bathymetric and sidescan data in deep sea over a wide swath of up to 140 degrees. The system is fully realtime-compensated for roll, pitch and yaw to guarantee full coverage even under severe environmental conditions. The implemented swept beam technology is superior to any other realtime motion compensation technology available on the market. The Windows based SEA BEAM 3012 offers a depth performance of 11000 meters with still 110 degrees fanwidth resulting in a seafloor coverage of 31 km. The SEA BEAM Water Column Imaging (WCI) option logs water column imaging data and displays real time images from the water column, both below and at the sides of the vessel.
