WM-200 is the first windmeter with wind vane, a USA-made fluxgate compass for digital wind direction, and that calculates crosswind & head/tail wind readings. Unlike traditional compasses, the WM-200 reads when held vertically and can be used for taking bearings. Temperature and wind chill are also included to make this a comprehensive unit for sailors, shooters, radio-controlled flyers, among others. WM-200 can be tripod-mounted and accommodates the Model SM-WT wind tunnel accessory for very precise measurements. All WindMates meet NIST calibration standards and wind speed accuracy tested better than +/- 3%. 2-Year Warranty.
