The Smart Alternative!

Airmar’s New ST800 and ST850 Smart™ Sensors feature

embedded micro-electronics. Speed and temperature signals are

processed inside the sensor and can be displayed on any radar,

chart plotter, or device that accepts NMEA 2000

data.

Minimize Your Drag

The ST850 is Airmar’s standard, thru-hull, speed and temperature

sensor. The plastic, bronze, and stainless steel outer housing

options are available to meet all hull requirements. These

low-proﬁle housings are nearly ﬂush and minimize drag with

only 5 mm (3/16”) extending outside the hull.

Eliminate Turbulence

The plastic P217 and bronze B119 countersunk ﬂush outer

housings are easy-to-install. The plastic P314 and bronze B21

outer housing options have a traditional beveled-edge for ﬂush

mounting. Flush-mount housings eliminate turbulence for

accurate readings at high-speeds. They are the optimal choice

for installation in racing sailboats and high-speed powerboats.
