The Echotrac MKIII is the only survey echo sounder that has interchangeable, plug and play modules, for a high-resolution thermal paper recorder and a full size color LCD chart with data storage and playback. Both High and Low channels feature auto frequency tuning to precisely match the transceiver to the transducer. This eliminates surface noise caused by transducer ringing and increases echo strength.

Operator selectable TVG curves optimize the MKIII for bottom detection or side scan operation. The Echotrac MKIII features 4 serial ports and Ethernet interface for maximum data input/output flexibility. Typical inputs are from heave compensators and DGPS receivers. Output formats are Odom, Atlas Deso 25, NMEA 0183 and Heave. Power input is 110-220 V AC / 24 V DC.
