Skymaster allows you to track weather in the palm of your hand! Radio/TV reports cover a large area, but Skymaster's data is specific to your location. Unlike other units, the jackknife case gives you the most accurate measurements--your hand's heat/moisture won't influence the environmental sensors. The Honeywell humidity sensor and the Swiss-made barometer can be easily re-calibrated and the unit has a weather alert if the barometric pressure rises or falls 6 millibars over 3-hrs. Skymaster can be tripod mounted using the optional tripod mounting fixture. SM-28 wind meters are designed with a wind speed accuracy of better than +/- 3% and have a 2-Year warranty.
