EASY TO OPERATE
The EA640 has been designed for the professional hydrography community. For maximum flexibility and ease of operation, the EA640 echo sounder uses a Microsoft Windows® operating system. The EA640 software can be run on any Windows compatible commercial computer.
Wideband frequency sweep (FM) in combination with advanced signal processing gives an exceptionally good signal to noise ratio and range resolution. With FM sweep the echo sounder range does not have to be sacrificed for resolution.
REPLAY AND STORAGE
The EA640 offers an 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
