No need for a fancy, expensive electronic wind meter. This cool looking and functional windsock has a 14" (36 cm) front diameter and is about 64" (163 cm) long. The front hoop is flexible plastic and is weighted at the bottom to keep the sock right-side up. It has a 4-line bridle with snap-swivel clip. The pole is not included, but you can use a telescoping painter's pole or even a cheap piece of PVC tubing would be fine. A simple glance at the wind sock will give you a good estimate on wind speed and more important which direction the wind is blowing from.
