Maretron’s new WSO200 is a marine ultrasonic weather station that accurately measures wind speed and direction, air temperature, barometric pressure, relative humidity, windchill factor, heat index and dew points. Wind measurements are calculated using six ultrasonic sensors in a delta configuration, with no moving parts to wear out. The WSO200 is NMEA-2000 certified, which allows for display on an MFD using N2KView software. The compact WSO200 sensor mounts on a standard marine pole mount, and it has an IP67 waterproof rating. The WSO200 was named Best New Product by a panel of judges at the National Marine Electronics Association conference in late 2022. $595; maretron.com
