Abstract: A combination of a movable structure (adapted to ride on or over a surface while supporting or carrying at least one person) and a velocity-measuring device which includes means responsive to air flow develop an electrical signal representative of current velocity of the movable structure. A voice synthesizing means, responsive to the electrical signal representation of current velocity, provides periodic voice synthesized audible outputs indicative of current velocity of the movable structure. The movable structure may be a snow ski, a water ski or a skateboard, as well as a number of other sport participating implements, such as a bicycle, an ice boat and the like.
