Garmin AIRMAR® DST820 Smart Transducer

This plastic thru-hull NMEA 2000® smart transducer combines precise depth, speed and temperature signals with attitude sensing for heel/trim and pitch/roll data. It can read depths to 100 m (330 ft) and offers fast 5 Hz water speed signal output for smoother visualisation on compatible chartplotters or other displays.

Wireless Bluetooth® connectivity makes it easy to manage calibration of sensor data through the AIRMAR Cast™ app interface. And the 235 kHz sensor operating frequency helps prevent mutual interference with other echosounder devices on the vessel. The transducer’s wide, fan-shaped beamwidth of 10 x 44 degrees enables it to find bottom even when installed on steep deadrise hulls or heeling sailboats.
