Airmar ST850 NMEA 2000 Smart Speed & Temperature Sensor Item # 1084603
Description
The ST850 is a low-profile, retractable, thru-hull sensor that computes accurate speed and temperature data and sends it to any NMEA 2000® network. These low-profile units are nearly flush, minimizing drag with only 3/16" (5 mm) extending outside of the hull. The housing features a water valve which minimizes water ingress into the boat when the retractable insert is being replaced with the blanking plug.
