With an incorporated digital compass, the Kestrel 4500 measures and logs wind speed along with wind direction. It also calculates crosswind and headwind/tailwind with reference to a user-set target heading and stores the information along with every other environmental reading in its 2000-data point memory.

Pair the 4500 with the Kestrel Portable Vane Mount and you have a complete, portable weather station that is the ultimate in portability — packing down into a 3 × 8 inch pouch and weighing under 9 ounces.
