Airmar ST800 NMEA 2000 Smart Speed & Temperature Sensor

The ST800 speed and temperature sensor processes digital signals inside the thru-hull housing. Then this Smart™ Sensor sends data to a chart plotter, radar screen, or digital display in NMEA 2000® format. These low-profile units are nearly flush, minimizing drag with only 3/16" (5 mm) extending outside of the hull.
