Wind Wizard

Reads wind speed in miles/hour, meters/second, and Beaufort. Readout dial is supported on sapphire jewel bearings and steadied by a rare earth magnetic dampening system. Folding handle quickly and securely latches into place. No batteries needed. Dimensions: 3-5/8" x 2-7/8" x 1" (92 x 73 x 25 mm) with handle folded. Weight: 2.5 oz (71 g). Measures wind speed from 0 - 60 mph.

Turbo Anemometer

The Turbo Anemometer 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 special three digit display is used for extra resolution and provides excellent viewing contrast in bright sunlight. A handy switch selects between four different scales—knots, feet per minute, meters per second, and miles per hour—for unmatched versatility. Unit is compact size (2.6 x 4.7", 7x 12cm) and light weight ( 3oz., 85g). Measures wind speed from 0 - 99.9 mph.
