Details:
Kestrel weather systems offer multiple weather measurements in a handheld, compact, and field rugged package. Some of the performance features include low friction sapphire jewel bearing; protective cover with sure-grip overmolding; and data hold function. The Kestrel 4500 does just that with its built in digital compass. But it doesn't stop there. It also calculates crosswind and headwind/tailwind with reference to a user-set target heading, and stores the information along with all the other environmental readings in its 1400 data point memory.
