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 5 mm (3/16") extending outside of the hull.

ST800PV-N2 NMEA 2000 Speed & Temp Transducer

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