Airmar ST800 P120 235kHz NMEA2000 Transducer

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