Airmar ST850 P17 235kHz NMEA2000 Transducer

The ST850 is Airmars standard, thru-hull speed sensor. Digital signal processing inside the housing provides speed and temperature 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.
