EA440 Single Beam Echo Sounder

The EA440 is a high performance hydrographic wide band single beam echo sounder. The echo sounder is developed for hydrographic use in shallow to medium depth waters. It supports portable and hull mounted side-scan and sub-bottom light for shallow waters.

Ease of Operation

The EA440 has been designed for the professional hydrography community. For maximum flexibility and ease of operation, the EA440 echo sounders uses the Microsoft Windows® 7 operating system. The EA440 software can be run on any Windows compatible commercial computer.

System functionality

Wide band frequency sweep (FM) in combination with advanced signal processing gives an exceptionally good signal to noise ratio and range resolution. With previous CW echo sounders range had to be sacrificed for resolution.

Replay and storage

The EA440 offers internal storage of all raw sample data. This includes all external input sensor data for replay purposes. A highly flexible processing regime makes it possible to log high density complex raw data for advanced post-processing.

Individual screen presentation

You can set up the display picture to suit your special needs. You can choose different windows on the screen for echogram, A-scope and digital depth. You can even control all the functions in the EA440 with just a click on the screen. These functions include comprehensive context sensitive on-line help. Save your favourite settings and call them back when you need them.

Highly flexible channel set up

Up to eight high-power transceivers can operate simultaneously from the EA440. For improved performance, they are installed close to the transducers and linked to the combined display and processor with a single data cable. Available frequencies span from 30 to 500 kHz. Low frequency transducer (typically 10 and 15 kHz) may be supplied for sub-bottom light but with a maximum range of 300 m. A variety of highly efficient transducers is available to suit all your operational needs from extreme shallow to 3000 m water depths.

Hydrographic depths, side-scan and/or light sub-bottom

With the EA440, you can cover several applications with a single system. Instead of running separate systems with synchronization issues the highly flexible EA440 can cover different applications simultaneously. Individual transducer channels may also be reprogrammed to use different frequency band.
