Weather Data at Your Fingertips 300WX WeatherStation Instrument and CAST App Airmar’s ultrasonic 300WX WeatherStation® instruments redefine what’s possible in marine weather sensing. Delivering ultra-accurate, real-time weather data, these rugged, compact, and maintenance-free instruments have zero moving parts for unmatched reliability. These all-in-one multisensor captures up to seven critical environmental parameters and seamlessly delivers that data to the NMEA 2000® network and to mobile devices through Airmar’s intuitive CAST™ app. Airmar’s best-in-class WeatherStation instruments go beyond traditional weather sensing. Advanced measurements— including SOG/COG, pitch and roll, rate of turn, and position— combine with an integrated 3-axis compass and GNSS to enable dynamic True wind speed and direction from mobile platforms. The result: smarter data, greater precision, and total confidence in any conditions. New Features of the 300WX WeatherStation Instruments: • Enhanced wind speed accuracy: 1.5 knots RMS at 20 knots • Bluetooth® wireless connectivity for use with Airmar’s CAST™ app to view data, configure sensors, and perform firmware updates. • Added communication protocols: J1939 and ISOBUS • Automatic baud rate detection for J1939 and ISOBUS (250 kbps / 500 kbps) Ultrasonic Wind Measurement Dynamic True and Apparent wind speed and direction with no moving parts Barometric Pressure Accurate atmospheric pressure measurement Air Temperature With calculated heat index and wind chill on 300WX Relative Humidity Field serviceable RH sensor with calculated dew point (300WX only) GNSS-Enabled Position, COG, SOG, time stamping 3-Axis Compass With dynamic stabilization 3-Axis Rate Gyro For rate-of-turn data 3-Axis Accelerometer For pitch and roll Wireless Communication to CAST App For viewing instrument data, configuring sensors and

300WX Multisensor The WeatherStation 300WX is a good choice for mobile, or stationary, weather-monitoring applications.

The Airmar CAST™ app connects directly from iOS and Android™ Smart devices to Airmar's 300WX WeatherStation Instruments. CAST connects using Bluetooth allowing users to configure sensors and outputs directly from a mobile device at distances up to 33 meters (100')*. This convenient feature enables users to connect to the WeatherStation wirelessly to perform firmware updates, rather than removing the instrument from a mast to do so. The CAST app also provides customizable data display layouts in digital, graphical, or hybrid formats to view current weather data. *BLE quoted distance for outside...
