The 4000 is unparalleled in its ease of use and totally customizable navigation and data display. In addition to measuring the current conditions, it tracks and stores up to 2000 sets of data, and data can be uploaded to a PC with the optional Kestrel Interface.

Durable? You bet. The 4000 has been subjected to impact, water submersion and extreme temperature tests, and keeps on working. Kestrel 4000’s have been put to the test in some of the harshest conditions on the planet. U.S. Special Forces, combat weather teams, wildland firefighters, smoke jumpers, Mt. Everest expeditions and IRL pit crews are just a few who rely on a Kestrel 4000 to provide them with the crucial environmental data they need. Watch the Weather Channel during a hurricane, and you’re sure to spot a Kestrel 4000 being wielded by an intrepid on-screen meteorologist.

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.
