Know at a glance how hard the wind is blowing with this wind speed indicator! A spinning cupwheel mounted on your rooftop or boat mast uses free wind energy to instantly register every gust of wind in real time. The decorative and elegant spun silver face of the highly polished brass dial accurately displays the wind speed from 0 - 100 mph (0 - 60 kph). The rugged rooftop transmitter is constructed of a marine alloy of aluminum for many years of trouble free operation.

The optional A.C. powered Peak Gust Register records the highest gust, which displays when you press a small button at the top of the dial.

Includes 6" diameter dial, all cable (50 ft) and hardware for easy owner installation. Flush mount.

Five year limited warranty.
