Here`s the one that started it all! Measuring wind is a breeze with the Kestrel 1000. We developed the Kestrel 1000 Pocket Wind Meter in 1995 when NK’s 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. Kestrel Weather & Environmental Meters are designed & manufactured in the U.S.A and are backed by our 5-year warranty. Innovatively designed for stability and accuracy in abrupt condition changes. Rugged and durable, Kestrels are drop tested, waterproof and designed to float if dropped in water.

The Kestrel 2500 Handheld Weather Meter measures wind and temperature with total accuracy, and has the added benefits of an air pressure sensor that provides altitude and barometric information. Kestrel 2500 technology enables you to follow changes in air pressure that help predict impending changes in the weather. Factor in the 2500`s digital altimeter, and you have most of the weather information you need for outdoor activities ranging from model airplane flight to rifle practice. 

The Kestrel 2500NV takes the great features of the Kestrel 2000 and adds in a pressure sensor.  Predict fish and wildlife activity as well as when bad weather is headed your way with the three-hour pressure trend indicator. With its easy-to-use digital pressure altimeter, you have the perfect instrument for any outdoor activity - get conditions in seconds right in the palm of your hand. In addition to predicting weather activity, barometric pressure also influences a bullet’s trajectory, which is why the Kestrel 2500NV is used by shooters and hunters when accuracy is important.
