Kestrel 3500 Weather Meter Description：

Datasheet User's Manual

Split-second decisions in the field leave no time for guesswork. Get every environmental condition in seconds with the affordable, reliable Kestrel 3500. The Kestrel 3500 pocket weather meter is a rugged, multi-function wind and weather meter that measures all the environmental variables, including wind speed, to calculate accurate ballistic solutions and train your environmental insight at the range. Designed to be your trouble-free companion, the Kestrel 3500 includes a hard, rubberized slip-on cover that protects the display and impeller, even when tossed in your range bag or pack.

Note:The Kestrel 3500 in Olive Drab with NV has a night-vision preserving backlight that helps users 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 much dimmer than standard backlights, making them 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, and 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 occur again. Light in the red spectrum does not cause this "bleaching out," preventing night blindness and night vision fatigue.
