DST-810MSF Bronze Thru-Hull, Digital Depth, Speed, Temp Sensor, NMEA2000 Airmar B617V Housing Style TransducerThe DST-801MSF offers depth, speed, and temperature in a single, 51 mm (2”) fitting. Only one hole through the hull simplifies the installation — an attractive feature for boat builders and boat owners alike. Patented, speed-signal-processing and upgraded 5 Hz (5X per second) speed-through-water 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 DST-810MSF's reliable temperature sensor.The DST-810MSF features a new Wireless connectivity to Airmar's CAST App, allowing you to calibrate the sensor, add depth offsets, and more.Features:Depth, speed, and temperature in one compact bronze housingFast-response temperature sensor provides ±0.2°C (±0.1°F) accuracyWeight: 1.6 kg (3.5 lb)Acoustic Window: Urethane HullDeadrise: Up to 22°Data Update Rate: 1 per secondMinimum Sounding Depth: 0.5 m (1.6’)Maximum Sounding Depth: 70 m (230’)Pressure Rating: 3 m (10’)Pulse Rate: 20,000 p/nm* (5.6 Hz per knot)—*p/nm = pulses per nautical mileSmart Sensor Supply Voltage at 100% Sound Power Output: 11.5 VDC to 25 VDCSupply Current: 40 mAStandard Cable Length: 6mNMEA 2000® Load Equivalency Number (LEN): 4
