Garmin Airmar DST820 Depth/Speed/Temp Thru Hull Smart TransducerThis 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. - Transducer frequency: 35 kHz
- Transducer power: 100W
- Transducer beamwidth: 100 x 44 degrees
- Transducer maximum depth: 330ft
- Transducer Measures: Depth, Temperature and Speed
- Transducer number of pins: NMEA 2000
- Transducer supported deadrise/transom angles: 0 to 22 degree
- Transducer frequency: 235 kHz
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. |
