Only one hole through the hull simplifies the installation - an attractive feature for boat builders and boat owners alike. 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 DST-800MSF's reliable temperature sensor.Standard Features:Depth, speed, and temperature in one compact bronze housingFast-response temperature sensor provides ±0.2°C (±0.1°F) accuracyWeight: 1.6kg (3.5lb)Acoustic Window: UrethaneHull Deadrise: Up to 22°Data Update Rate: 1 per secondMinimum Sounding Depth: 0.5M (1.6')Maximum Sounding Depth: 70M (230')Pressure Rating: 3M (10')Pulse Rate: 20,000 p/nm* (5.6 Hz per knot)Smart 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*p/nm = pulses per nautical mileWARNING: This product can expose you to chemicals which are known to the State of California to cause cancer, birth defects or other reproductive harm.
