Limited Time Special! - Purchase (1) or more and receive (1) FREE Spare Battery With Each 2500 - 3500 Series Meter Purchased! The Kestrel 2500 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 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.
Available in the 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.
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. Made in the USA!
