AIRMAR WeatherStation® Multisensor 120WX, 220WX

Available Models: 120WX, 220WX

From racing and cruising sailboats to yachting and commercial fishing, Airmar has WeatherStation® products specifically designed for your marine application.

The WX Series WeatherStation instruments meet a growing need for real-time, site-specific, weather information. For applications where theoretical and apparent wind are

important, the 220WX is recommended. It includes a 10Hz GPS, three-axis solid-state compass, rate gyro and tilt sensors. This model features configurable

NMEA 0183 and NMEA2000® digital data outputs, providing unparalleled versatility for all your weather monitoring needs.

Both models offer a truly best-in-class solution at a better price than any other weather monitoring system on the market today.
