Kestrel 4500 Weather Tracker

For years Kestrel customers have been asking for wind direction along with wind speed. Now, 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 2000 data point memory.

Pair the 4500 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.

NV Version for night-time activities

Kestrel 4500 night vision

The Kestrel 4500NV was improved to be even more suitable for night-time activities. The Kestrel® NV units are olive drab with a visible red backlight, which helps sustain the user's natural night vision. Military personnel and pilots flying in darkness are often concerend with preserving their night vision.

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 units' red backlight is also much dimmer than a standard backlight, making it more difficult to detect with the naked eye in night operations.
