Skywatch Pro

Ideal for free flight, nautical or all outdoor activities that need a wind measurement it says on the instructions. The pro gives current wind speed, Average wind speed, Maximum wind speed and distance travelled (air). The maximum is always displayed in the top right of the display and the center display toggles through the above measurements. The travelled distance is calculated on the average wind speed times the time that the unit is on (particularly useful for something, I just haven't figured what yet). The impellor can be attached in a multitude of orientations with respect to the instrument. The unit is sealed and weather proof with a battery (non-replaceable) guaranteed for 100,000 hours of operation.
