Targeted toward and practically required for wildland firefighters in both fighting fires and controlled burn situations.  This Kestrel 3000 model was a principle factor that changed firefighting equipment standards from the previous standard, the belt weather kit.  It cut the weight of dated weather packs, confusion, and time, to this minimalist approach that was revolutionary in firefighting, where users lives literally depend on the accurate weather data their Kestrel 3000 provides.

NK was the first to provide accurate relative humidity measurements from a hand-held weather meter, and the Kestrel 3000 features two patents on its humidity measuring sensors.
