On the Ground ......................or in the Air
Since 1949
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, 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.
