Airmar ST850 NMEA 2000 Plastic TH Speed/Temp

Brand: Airmar
Part Number: ST850PV-N2
$228.13
The ST850 is our 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 either analog or NMEA 2000® formats. The plastic P17, bronze B17, and stainless steel SS577 housing options are available to meet most hull requirements. These low-profile units are nearly flush and minimize drag with only 5 mm (3/16") extending outside of the hull.
