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.
