Kestrel Pocket Weather Meters With Night Vision Backlight

The Kestrel 2500, 3500, 4000, 4400, 4500 and 4600 are all available with night vision protection. The Kestrel Horus and Kestrel Applied Ballistics models are provided with this feature as default.

With these instruments, the backlight incorporates an optical filter which reduces the overall brightness and minimizes blue and green spectrum light. This helps preserve the eye's natural night vision in dark conditions.

Additionally, Night Vision backlights are also much dimmer than a standard backlight, making it more difficult to detect with the naked eye in night operations - a useful feature for military personnel. 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.

The Night Vision models are all available in olive drab, the Kestrel 4000 and 4500 are also available in desert tan.

All the other features of the Kestrel Night Vision instruments are just the same as their more colourful counterparts.
