Description
WM-200 has an integral, visual wind vane to assist with orientation to the wind, a USA-made fluxgate compass for digital wind direction measurement, and it calculates crosswind, head/tail wind readings. Unlike traditional compasses, the WM-200 reads when held vertically and it can be used to take a bearing on a distant reference point. Temperature and wind chill are included to make this a comprehensive unit for sailors, shooters, and radio-controlled flyers, among many other applications. WM-200 can be tripod-mounted and accommodates the Model SM-WT wind tunnel accessory for very precise wind direction measurements. All WindMates are designed with a wind speed accuracy of better than +/- 3%.
