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 bullet’s trajectory, which is why the Kestrel 2500 is used
by shooters and hunters when accuracy is important. US Olympic Rifle
Champion Shooter Lones Wigger wouldn’t 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.” 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. Manufactured in the USA!
