It uses the very latest in ultrasound technology to reliably and accurately measure the wind's speed and direction, including wind gusts. Its high standard of mechanics and high quality plastic design make this device weatherproof, resistant to UV, hail and strong winds. The wireless connection between module and station extends  to a 100 metre  range.   The Wind Gauge is equipped with four ultrasonic transducers that emit continuous signals, measuring wind speed and direction. Using variations in these signals it's able to measure the  speed and direction of the wind.  The measurements taken by the Wind Gauge  are configured by custom  preference, allowing for customised alerts and notifications.   Thanks to the Wind Gauge, you can now choose the best time to go sailing, biking, golfing and more.
