SEA BEAM 3012 - MULTIBEAM SONAR

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.
