The NK Kestrel Pocket Wind Meter is very accurate, very tough and very affordable. You can carry it in a pocket, hold it in one hand, and use it whenever and wherever you need to know wind speed. To measure wind speed, the Kestrel relies on a precision ultralight anodized aluminum impeller mounted in jewel bearings. The Kestrel is waterproof and floats. The hard case slips on and off easily and protects the display and all moving parts from damage.
Performance is guaranteed for one full year.
