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. The 200, 300, and 350 models feature a digital, USA-made fluxgate compass which allows wind direction, cross/head/tail wind calculations, and more, all on an easy-to-read LCD display. 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.
Unlike traditional compasses, the WM-200 reads when held vertically and can be used for taking bearings. The WM-200 includes all of the same great features of the WM-100 with the addition of temperature and wind chill, making this a comprehensive unit for shooter or sailors, among others. The unit is very simple to operate. The Mode button toggles you through each of the six features. Units can be changed by pushing a second button, while a third button operates settings for compass calibration. Using a traditional compass, you can check the accuracy of the WindMate 200 digital compass. If it needs to be recalibrated, the process is pretty easy: You just enter the recalibration from the compass window, rotate the WindMate 200 twice at about 15 second intervals, and press the SET button again to finish. An error will be indicated if it was done incorrectly. Compass is accurate to +/- 2 degrees. Wind chill accuracy is +/- 1.8 degrees F.
