Kongsberg Maritime EM 304 MKII

MULTIBEAM ECHO SOUNDER

The modular, state-of-the-art EM 304 MKII performs accurate, high resolution seabed mapping in shallow to deep waters at depths of more than 10000 m. The evolution of the EM 304, the EM 304 MKII broad range of functionality supports simultaneous collection of multiple data types, saving time in the planning, execution and analysis phase. A low noise echo sounder, EM 304 MKII with ocean depth capability delivers superior data requiring minimal post-processing.
