Jeffery Wind Flag DIRECTIONAL BALL*
This directional ball is crafted from Styrofoam and vacuum formed vinyl. It is lightweight and offers good visibility to 125m or more if viewed through your scope. Since this ball is lightweight, flag sensitivity remains high. Best used on days when the winds are in excess of 10-15mph. Ball is 6cm in diameter and is designed to slip on the front of a wind vane. *This ball is constructed to work with Jeffery WindFlags. If you require something to work with your particular set up, please contact us.
