Compatible with the following instruments:
Compatible hull material:
- ST70 (direct connect to ST70 backbone, no pod required)
aluminum and fiberglass
Hole diameter for installation:
Operates at 235kHz so there is no interference with your 50/200 kHz fishfinder transducer.
Airmar's Smart™ Sensors have embedded microelectronics, meaning the signal is processed from within the transducer itself, eliminating the need for an ST70 transducer pod.
Patented, speed-signal-processing enhancements provide excellent paddlewheel accuracy below 5 knots (6 MPH) and smooth linear output at all vessel speeds. The transducer’s wide, fan-shaped, fore-aft beam is able to find bottom even when installed on steep deadrise hulls or heeling sailboats. You also get true water-temperature readings with the DST800’s reliable temperature sensor.
