Abstract
Presented is a method and apparatus that permits a skier to control the speed at which he descends a ski slope. In terms of structure, the invention includes a pair of probes mounted on each ski that protrude below the running surface of the ski and thereby drag in the snow. The probes may be controlled as to the depth of penetration of the snow either before the skier starts his run, or during his descent. Having deployed the probes, added manueverability control is achieved merely by conventional body movements which affect the depth to which the probes penetrate the snow.
