Kestrel 4000 Windmeter for Kiteboarding

All Kestrel Pocket Weather Meters are made in the USA and covered by a 5-year warranty against manufacturing defects. Additionally, every single Kestrel manufactured is calibrated for every single value, either directly against NIST-traceable standards or against an intermediary standard that is calibrated daily. Every unit is shipped with a FREE Certificate of Conformity that states what calibrations were performed, and the certified performance specifications.

The Kestrel 4000 windmeter is the most comprehensive pocket weather meter on the market. For just under 4 ounces, you get every environmental reading with the press of a single button. 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.
