Davis Instruments

Davis Instruments started in 1969 selling sextants, a device that uses the angle between the horizon and a celestial body like the Sun, Moon, or a Star to calculate latitude and longitude. Davis’s first weather device wasn’t until 1984, the TurboMeter – a handheld wind meter for mariners. The Digital Weather Pro in 1988 was the first weather station, and WeatherLink followed in 1991, the first comprehensive weather station software available. The original Vantage Pro wouldn’t arrive until 2001 (the Vantage Pro2 launched in 2005), and the Vantage Vue in 2009. Davis Instruments was sold to AEM after the founders’ retirement in 2019, and remains at its original Hayward, California headquarters.
