Every Kestrel hand held weather station features a patented user-replaceable sapphire jewel bearing impeller. They are highly accurate and will take readings as low as 0.3 meters per second.
After excessive wear (approximately 400 hours of use), or use at high speeds, the impeller accuracy may start to drift. This replacement impeller is necessary only when the original impeller is damaged or worn.

This compass has 2° graduation lines as well as large numerals at every 20° mark, and its clear base plate makes it easy to read a map and set bearings. To get a precise wind direction, simply point the large base plate arrow into the wind, turn the bezel to match the red North indicator to the red needle, and read the wind direction at the base plate arrow. This full-featured compass has a declination correction scale to allow you to make quick adjustments of map bearings to field headings, a sure-grip dial and ergonomically-contoured base plate, and includes inch and millimeter rules for mapping and plotting.

Additional Accessories That Can Be Used
With Kestrel Wind Meters |
|
Maximize your wind meter accuracy by using the Speedtech Instruments SM-WT Wind Tunnel. Can be used with all Spectrum and Kestrel handheld wind meters. Meets NCAA Track and Field requirements. The Speedtech SM-WT Wind Tunnel provides precise wind velocity in a specific direction for precision shooting and other uses. The wind tunnel slides easily over the top of the wind meter (no tools required), pressing until the center of the tunnel is snug with the top of the wind meter. Looking through the tube, the impeller should be visible. If used with a Kestrel wind meter it will not fit as snugly.
