Airmar UDST820 TriSonic Plastic Thru-Hull Transducer - N2K

Overview

UDST820 TriSonic Plastic Thru-Hull Transducer - N2K

TriSonic Smart Sensor combines a depth sensor, ultrasonic speed sensor, water temperature, and heel and trim data into one sensor. It delivers unmatched reliability and accuracy without the need for paddlewheel maintenance. Its ultrasonic speed solution features no moving parts, eliminating cleaning or wear concerns, making it a high-precision, low-maintenance option for power and sailboats of all sizes. The TriSonic Smart Sensor, along with the CAST™ app, simplifies the calibration of speed-through-water. The Airmar CAST™ App connects directly from iOS and Android™ Smart devices to Airmar’s Bluetooth® enabled TriSonic Smart™ sensors and makes configuration simple with intuitive menus and guided calibration. View data from the sensor in digital or graphical format, quickly turn on or off NMEA 2000® PGNs, configure offsets and more.

CAST App for Speed and Depth Calibration:

Highlights

• Ultrasonic speed (no paddlewheel)
