Abstract: An assistance device for sports training of sports requiring rhythmic activity. Audible prompts are delivered to the user so that he or she knows when to engage in a certain activity of the sport, the primary example being that of the golf club stroke. A clock provides a sequence of pulse signals at a constant time interval, with the interval being adjustable by the user. Multiple sound generators selectably receive the clock signals and generate corresponding audible sounds. A timing sequence controller correlates the multiple sound generators for the training effect. A visual display is included to give the user rapid understanding of how the device is used.
