Portable WindMate wind meters have been reviewed by experts in the field and have won various industry awards. Each unit is only 5.5 inches long when closed, and weighs just over 3 ounces - perfect for taking to the field, or adding to that already-stuffed range bag. The unique, jackknife-style case allows more precise wind speed readings than other meters, because your hand is distant from the wind impeller, allowing undisturbed air flow measurement. It then folds to protect the unit when not in use. WindMate meters come with a wind vane to ensure accurate measurement on the wind axis. All units can be tripod mounted and will accommodate the Model SM-WT wind tunnel accessory for more precise readings as a stationary sensor or for long-range shooting. All WM-series meters use the readily available, CR-2032 lithium battery, included with each meter, which provides approximately 400-hours of operation. WindMate wind meters meet NIST calibration standards, are wind speed accuracy tested to better than +/- 3% and have a 2-year warranty.
If you just need wind speed, this is the instrument for you! The WM-100 has Swiss-made impeller components, is water resistant, shockproof and floats. Measures wind speeds from 0.8 - 89 MPH with reading in tenths. Will display wind measurements in Knots, MPH, KM/H, Ft./Min., M/sec, Beaufort speed ranges from 1-12, current and maximum wind speeds and average wind speed. Comes with an adjustable lanyard. The case is water resistant, shockproof, and the jackknife design allows for the most accurate measurements, as your hands heat and moisture do not interfere with any sensors.
