This instrument will let know at the glance how hard the wind is blowing! A spinning cupwheel mounted on your boat mast or rooftop top uses free wind energy to instantly register every gust of wind in real time. The elegant spun silver face of the highly polished brass dial accurately displays the wind speed from 0 - 100 mph (0 - 160 kph). The rugged rooftop transmitter is constructed ofa marine-alloy of aluminum for many years of trouble-free operation.
Watch as a storm passes by - it's fun and entertaining for the whole family!
Includes 6" diameter dial, all cables, and hardware for easy owner installation!
