UDST800 Ultrasonic Smart™ Sensor

Ultrasonic Depth, Speed & Temperature Sensor

Airmar’s new UDST800 just turned your maintenance time into more cruising time…and made your boat smarter too. Ultrasonic depth, speed and temperature in one single housing with no moving parts makes this sensor capable of accurate readings at all vessel speeds. What sets this multisensor apart from the traditional speed paddlewheel sensor is its accuracy at both very low-speeds between 0.5 and 5 knots (0.6 and 6 MPH), and at high-speeds up to 50 knots (57 MPH).
