Kestrel 4500
Pocket weather tracker

by Nielsen Kellerman (4500)

New for 2007, the Kestrel 4500 provides wind direction with its wind speed measurement thanks to 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.

2500NV - Night Vision Configuration

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.

Military personnel, SAR, and pilots flying in darkness are often concerned with preserving their night vision. So Kestrel created the 'NV' line to address thsi issue.
