STN Atlas Marine Electronics has expanded its DESO range of survey echosounders with its Atlas DESO 300 — a new portable unit — designed for operation aboard small survey vessels and inflatable watercraft.
The lightweight system holds operating frequencies of 210, 200, 40 and 33 kHz and sealed keypad controls, and features integral recorder, digitizer and transceiver functions inclusive of LCD display facilities, as well as 8.5-in. thermal printer. Depending on
transducer arrangements, depth range is 0.2 to 250 m (0.7 to 820 ft.), while resolution stands at 0.01 m (0.1 ft.)
The system can also be optionally supplied with an integral DGPS receiver with surroundings that can be automatically annotated with GPS position — providing complete surveys.
