The Kestrel 2500 Pocket 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 2500's sensitive and user-replaceable impeller technology provides accurate wind speed info. Additionally, an external temperature sensor and waterproof casing allow you to gauge the temperature of water (it even floats) and snow, as well as the open air. A hard slide-on case, lanyard, and battery are included.
The Kestrel 2500 was originated as a basic model for long range shooters at an affordable price and someone who didn't need the ballistic features build in like the 5700 Elite. A simple video shows how to achieve station pressure with a Kestrel 2500.
For those using it at night, the Olive Drab NV version of the Kestrel 2500 features a night-vision preserving backlight. Backlight incorporates optical filter to reduce overall brightness and minimize blue and green spectrum light to preserve night vision. (Note: This backlight appears soft greyish pink, not "red", and is still in the visible spectrum, so is not compatible with night-vision equipment.)
