DESCRIPTION

OVERVIEW

The Speedtech Instruments SM-28 Skymaster Weather Meter allows you to track weather in the palm of your hand! Radio and television reports cover a large area, but Skymaster's data is specific to your location. Unlike many 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 storm audio alarm if the barometric pressure rises or falls 6 millibars over 3-hrs. Skymaster has a tripod fitting, is water resistant and floats. For the most precise measurements, it can be used with Speedtech's wind tunnel (model SM-WT).

Not sure as to how accurate the sensors are? For $170 you would think that they would be consistently accurate. Also, you better have 20/20 vision to see parts of the screen that have very small print. A backlight would be helpful. It is nice to have a portable device for obvious reasons.
