The Davis Turbo Meter provides uncommon accuracy, sensitivity, and pocket-sized convenience. It is based on the principle that a freely turning turbine will rotate at a speed directly proportional to the wind speed. To insure maximum sensitivity and accuracy, the turbine is suspended on sapphire jewel bearings, and its rotation is sensed by an infrared light beam which adds no friction. The resulting signal is processed electronically by an LSI (Large Scale Integrated) circuit for improved reliability and reduced size. A handy switch selects between four different scales—knots, feet per minute, meters per second, and miles per hour—for unmatched versatility. A special three digit display is used for extra resolution and provides excellent viewing contrast in bright sunlight.

Measures wind speed from 0-99.9 mph
With the introduction of the Windex 10.Sport, Windex wind vanes continue to offer exceptional performance at the best value of any wind indicator worldwide. The secret is in the sapphire jewel suspension bearing, large fin-low inertia van, and easy-to-read, fully adjustable tacking tab system.
Reflector tape on the vane and tacking tabs make Windex 10.Sport easy to see day and night. Windex vanes are sturdy and when installed properly, offer many years of use. They have been wind tunnel tested to wind speeds of 80 knots!
Windex 10.Sport has a 10" (25 cm) vane. Includes glass reinforced polycarbonate J-Base for side, top or front of mast mounting on most dinghies, smaller boats and sport boats. Stands just 9.25" (23.5 cm) tall and weighs 1.2 ounces (31 g).
