Following on from the successful MKII, the MKIII is an entirely new design incorporating cutting-edge technology and features in a more compact package. 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. Frequency tuning in 100 Hz (low freq.) and 1 kHz (high freq.) steps can be manual or automatic from 750 kHz to 10 kHz, thus matching a wide variety of different transducers, including side scan. 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.
