The Windicator Wind Drift Target Hold Over Indicator is the most comprehensive wind flag on the market. The wind pressure meter shows the wind speed in MPH while showing the direction of the wind as well as ground turbulence caused by swirling or inconsistent wind bursts. With some practice and notes on the included "Plot Your Shot" charts, you will be able to quickly read the flag, and adjust accordingly for changing conditions. Color indicators help to reduce stress while shooting benchrest, and when conditions are in the green you can shoot with confidence! The Windicator comes in a hard sided case for convenient transport, and assembles in minutes. The base is adjustable for elevation so you can place inside your line of sight. Each component is made to be long-lasting, and the bearings are super-smooth for more accurate wind readings. All-in-all, the Windicator is the finest wind reading station available!
