The new generation wide band hydrographic Echo Sounder
The EA440 is a new hydrographic multi frequency echo sounder with wide band technology. The EA440 has been developed for use in shallow to medium depth waters. A variety of highly efficient transducers are available to suit all of your operational needs, from extreme shallow (0.2m) down to 3000 m water depths.
The system supports both portable and hull-mounted side scan, and sub-bottom light for shallow waters. The operating software is in accordance with the new KONGSBERG standard MMI and it has an easy and intuitive user interface with extensive display capabilities.
