The Airmar UDST800P-N2 combines ultrasonic depth, speed, and water temperature measurement into a single thru-hull housing with zero moving parts. Designed for power and sailboats of all sizes, it eliminates paddlewheel maintenance while delivering high-precision data at speeds from a crawl to 50 knots. Advanced filtering and adaptive sampling keep accuracy consistent across varying boat speeds, water depths, and water clarity conditions — all over NMEA 2000.
