Understanding the environmental conditions surrounding a fire is critical. The Kestrel Fire Weather DROP can be deployed in seconds to begin capturing data from the start of the fire. DROPs are so small they can easily be clipped to a pack or belt loop, and so affordable they can be placed in multiple locations to provide unmanned monitoring. The DROP is powered by LiNK wireless data connectivity and the LiNK iOS and Android App – allowing for remote view of DROP readings as well as hands-free automatic data upload for review whenever the opportunity presents.
