The Kestrel 2500NV Pocket Weather Meter measures wind speed and temperature accurately, and has the added benefits of an air pressure sensor that provides altitude and barometric information. The Kestrel 2500 technology features a three-hour pressure trend indicator helps you predict fish and wildlife activity and know when the weather's going to turn nasty. Factor in the 2500's digital altimeter, and you have most of the weather information you need for long range hunting and shooting.
The Kestrel 2500's sensitive, user-replaceable impeller technology provides accurate wind speed information. The external temperature sensor and waterproof casing allow you to gauge the temperature of water and snow, as well as the open air. These are essential measures for long range shooters and military professionals to, and prove invaluable to outdoor enthusiasts, like skiers and mountain climbers, who need accurate and up to the minute weather information.
The Kestrel 2500NV has a night-vision preserving backlight which helps users to sustain natural night vision. This is a must for military, LE, and hunters. The NV's backlight incorporates an optical filter to reduce overall brightness and minimize blue and green spectrum light to preserve night vision. Additionally, NV backlights are also much dimmer than a standard backlight, making it more difficult to detect with the naked eye in night operations. This backlight appears soft greyish pink, not red, and is still in the visible spectrum, so is not compatible with night-vision equipment.
