Vigilant Wind Speed Instrument

The wind speed instrument that maximum was founded upon.Vigilant displays wind speed from 0-100 mph and 0-160 km/h, as well as high (or "maximum) gust. High gust is saved with the unique 'gust register', allowing you to monitor the highest gust even if you are not present when the wind occurs. Vigilant is self-powered by a rooftop sensor and requires no batteries or another power source to operate. Includes 60' cable, wind speed sensor, and mounting hardware. When used with the optional scale doubling switch, vigilant can record wind speed up to 200 mph.
