Kestrel 4000 Weather & Environmental Meter in Tactical Dress with Bluetooth® Classic in Desert Tan (DISCONTINUED) Overview
This model has been discontinued and replaced with the Kestrel 5000 Environmental Weather Meter.
The Kestrel 4000 Weather & Environmental Meter in Tactical Dress is the next generation of weather monitoring. You can now measure EVERY major environmental condition, easily and accurately, right in the palm of your hand.
Note: This Kestrel 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.
Tactical unit also includes:
- Tactical Molle Carry Case - Green Case for Olive Kestrels and Tan Cases for Tan Kestrels
