The Bathy-500MF is a state of the art electronic survey instrument used to generate precision chart recordings and digital data output.

Low power consumption, portability, ease of use, rugged splash-proof construction, and built-in communication interfaces for  navigation/data logging devices make the Bathy-500MF ideal for shipboard use.  Digital processing enables the instrument to offer fully automatic bottom digitizing capabilities.  When interfaced to a NMEA 0183 compatible position sensor, the Bathy-500MF provides the user with a complete integrated hydrographic survey system.  Multi frequency operations is available via menu selectable frequencies of 33, 40, 50, and 200kHz.
