This is a prize-winning, comprehensive weather monitor, which gives full environmental data specific to your location and includes a 48-hour history for every function, hour-by-hour and in a bar graph. The USA fluxgate compass reads when held vertically, gives wind direction in degrees and compass points; it calculates crosswind & head/tail wind. The compass can be calibrated for variation/declination and deviation. In addition to wind speed/direction, temperature, barometric pressure, altitude, and humidity, the unit includes wind chill, Wet Bulb, Dew Point, Delta T & Density Altitude. WindMate 350 gives an accurate weather forecast and an audio storm alarm alerts you to weather changes, even if the unit is off.

The instrument has Speedtech’s exclusive, patented Comfort Index, which is the effect of temperature, relative humidity, wind speed & sun intensity on the human body. The formula can be adjusted based on sun intensity and is superior to Heat Index. The case is water resistant, shockproof, & the jackknife design allows for the most accurate measurements, as your hands heat and moisture do not interfere with any sensors. WM-350 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%.
