Altronics PerformAIRE Pocket Weather Stations

Altronics PerformAIRE Pocket hand-held racing weather stations include weather-sensing and performance-calculating technology. Unlike other brands that claim to be for racing, PerformAIRE's patented calculations are based on measuring horsepower and performance of an internal combustion engine. Ultrasonic technology accurately measures wind speed and gust with no moving parts that can break or wear out. They are simple to use, and a joystick controls all functions.
