If wind speed is all you need, the Speedtech Instruments WM-100 WindMate 100 Wind Meter is the perfect instrument for you! The WindMate 100 includes a wind vane to ensure accurate measurements on the winds axis. Unlike many other wind meters, the jackknife case allows more precise wind speed readings because the users hand is away from the wind impeller, which then measures undisturbed air flow.
The WM-100 has Swiss-made impeller components, is water resistant, shockproof and floats. For long-range shooting, the unit can be tripod-mounted and uses the optional wind tunnel (model SM-WT) for very precise measurements. All WindMates meet NIST calibration standards and wind speed accuracy tested better than ±3%.
