PURPOSE:To eliminate the need for lower movement of a sight for checking during a sliding without freezing free from error against wind by inputting an actual speed of a ski with a required correction from a speedometer measuring section mounted on a human body or a skiing board to display. CONSTITUTION:A hot-wire anemometer 101 is mounted on the top surface of a skiing board 105, the side of a goggle 10 or the like, where wind hits being straightened during a sliding to measure a primary speed of skiing. Then, the value is inputted into a controller 102, where errors due to a natural wind velocity are corrected to compute an actual speed V, which is sent wireless or wired to be displayed 104 with a headup display device or the like. The anemometer 101 is operated electrically without mechanically operating part and thus, free from trouble caused by freezing. |
