The plastic Garmin Airmar DST800 thru-hull transducer provides depth, speed, and temperature data via a NMEA 2000 network to your compatible Garmin chartplotter.
The Garmin Airmar DST800 features smart sensors that have embedded micro electronics - the transducer element and signal processor are only millimeters apart. The signal from the depth transducer is processed right inside the sensor itself. All that is needed to receive depth, speed and temperature data is a single cable into a compatible NMEA 2000 network or display.
The wide port-starboard, fan shaped beam is able to find bottom even when installed on high-deadrise hulls or on sailboats when heeled.
