Kongsberg has released a new 30 kHz multibeam echo sounder system, the EM 304, used for high resolution seabed mapping from depths of 10 meters to 8000 meters.

As part of a new EM technology platform designed for future challenges, the EM 304 is compatible with a new Kongsberg developed datagram format.

“The EM 304 provides state-of-the-art survey vessel operators with the highest performance, most accurate mapping capability. The system replaces the EM 302 which has been the de facto industry standard since it was launched in 2006,” said Helge Uhlen, director sales Subsea.

The EM 304 takes advantage of features and benefits achieved in the development of the EM 2040 family and the EM 712.

For operations in Arctic waters, the system can be delivered with ice windows for protection of the transducers.
