Kestrel 1000

Kestrel Camp & Hike 1000 Wind Meter / Anemometer Blue 0 810. Measuring wind is a breeze with the Kestrel 1000. We developed the Kestrel 1000 Pocket Wind Meter in 1995 when NKs co-founder Richard Kellerman needed a reliable wind meter for flying his glider. Over 15 years later it looks a little slicker and it gives you the wind information you can count on with a simple reliable and accurate pocket wind meter. The Kestrel 1000 can easily be switched between mph km/h ft/min m/s knots and Beaufort.
