The Ski Speedometer. Measure your ground speed via this wrist borne speedo-gizmo. Peer at the digits in despair as you careen artlessly into the nearest bush with a guttural yelp of triumph. $299.95.
This is the only personal, portable device available that measures your ground speed and distance while skiing, snowboarding, or sledding, providing a readout on a wrist unit so you can easily track total range and best speeds. The small, wireless, coded radio-frequency transmitter attaches to your boot, leg, or waist and projects a radar signal to measure average ground speed in MPH and KMH, as well as maximum speed, pace in minutes per mile, distance in miles, total distance, and elapsed time.
