The Speedtech Instruments WM-200 WindMate 200 with Wind Direction & Temperature is the first wind meter with a wind vane, a USA-made fluxgate compass for digital wind direction, that also calculates crosswind and 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, making this a comprehensive unit that's ideal for sailors, shooters, radio-controlled flyers, and many others.
The WindMate 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%.
