The control circuit monitors ski performance at a given adjustment for a predetermined interval, thereafter determines an appropriate adjustment, then monitors ski performance at the new adjustment for the predetermined interval, and so forth. A gearing mechanism powered manually or by an electric motor can be provided to effect the automatic adjustment of the ski in response to an output of the control circuit. | |
