Plastic Thru-Hull, Smart Sensor(8-Pin)
Airmar: ST850

The ST850 is Garmin’s 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. These low-profile units are nearly flush and minimize drag with only 5 mm (3/16″) extending outside of the hull.

Easily collect your vessel speed and the water temperature with our speed/temperature sensor. This plastic thru-hull mount sensor uses a paddle wheel to determine vessel speed while the temperature sensor indicates the current water temperature. Speed and temperature information is collected and displayed on your device.

Garmin’s 8-pin sensor works on compatible Garmin sounders. It fits any deadrise/transom angles.
