  • Airmar ST850 BRONZE Thru-Hull NMEA 2000 Smart Speed and Temperature Sensor Transducer 
  • The ST850 is a low-profile, retractable, thru-hull sensor that computes accurate speed and temperature data and sends it to any NMEA 0183 display or NMEA 2000 network. These low-profile units are nearly flush, minimizing drag with only 5 mm (3/16") 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.
