Kestrel 2500NV 2500 Pocket Weather Meter with Night Vision Preserving Backlight

Kestrel 2500NV Pocket Weather Meter (Anemometer) Features Include: Current Wind Speed, Maximum Wind Gust, Average Wind Speed, Air, Water & Snow Temperature, Wind Chill, Barometric Pressure & Altitude w/ Night Vision! We are an Authorized NK Kestrel Dealer!

Our price for this product is the lowest NK allows it's dealers to sell it for. Anyone claiming to be a dealer who advertises this item or accepts best offers lower than our price is most likely not a Kestrel dealer. The Kestrel 2500NV takes the great features of the Kestrel 2000 and adds in a pressure sensor. A three-hour pressure trend indicator helps you predict fish and wildlife activity and know when the weather's going to turn nasty.

With its easy-to-use digital pressure altimeter, you have the perfect instrument for any outdoor activity. In addition to predicting weather activity, barometric pressure also influences a bullets trajectory, which is why the Kestrel 2500 is used by shooters and hunters when accuracy is important. US Olympic Rifle Champion Shooter Lones Wigger wouldnt trust any other instrument. The Kestrel Meter is essential for target rifle shooting. It helps me win matches, and I rely on it for accurate weather information.

This model includes NV Configuration. Military personnel and pilots flying in darkness are often concerned with preserving their night vision. Due to overwhelming demand from our military customers, the Kestrel NV line was added in 2005.

Note: The Kestrel 2500NV has a night-vision preserving backlight which helps users to sustain natural night vision. 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.

It takes 30 to 45 minutes for the average eye to adapt to darkness and maximize night vision. Even a short burst of white, yellow, green or blue light bleaches out the rod cell photoreceptors in the eye and causes night blindness until the entire adaptation process can take place again. Light in the red spectrum does not cause this bleaching out, preventing night blindness and night vision fatigue. Certified and Guaranteed Accuracy Every single Kestrel manufactured at Nielsen-Kellerman is calibrated for every single value, either directly against NIST-traceable standards or against an intermediary standard that is calibrated daily. What does that mean for the customer? They can be absolutely sure that their weather readings are accurate to the stated specifications. Some competing weather instruments claim the same specifications as Kestrel, but only Kestrel certifies their accuracy. CR2032 coin cell battery (Average life 300 hours).
