Overview
For years Kestrel customers have been asking for wind
direction along with
wind speed. The Kestrel 4500 does just that with its built in digital
compass. But it doesn’t stop there. It also calculates crosswind and headwind/tailwind with reference to a
user-set target heading, and stores the information along with all the other environmental readings in its
1400 data point memory.
Pair the 4500 Wind Meter with the Kestrel Vane
Mount and you have a data-logging weather station that sets up in seconds
and rotates in the slightest of breezes. Did we mention that the whole kit is the ultimate in portability? It
packs down into a 2 x 6 inch pouch and weighs under 8 ounces.
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 military customers, the Kestrel NV line
was added in 2005.
The Kestrel 4500NV 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.
