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.
My GPS will show all my speed data. Sure it may not use radar — but it’s also show altitude, direction, location and other goodies — and it costs less than this little dohicky.
