WeatherHawk WM-200 WindMate Hand-Held Wind Meter, Blue
This is the very first wind meter to incorporate wind direction measurement in addition to wind speed. Essential for sailors and shooters, the WM-200 is the fastest way to accurately read and then react to the wind conditions surrounding you. It also calculates the cross wind and head/tail wind with the touch of a button. This unequaled instrument comes with a two year warranty.
