1. A velocity meter particularly useful for measuring the velocity of a golf club during the swing thereof, said velocity meter comprising:

  • position sensing means for sensing when said golf club is in first and second pOsitions during the swing, first pulse generating means for generating a first signal pulse responsive to said club being in said first position, second pulse generating means for generating a second signal pulse responsive to said club being in said second position, means responsive to said second pulse for generating a ramp signal, enabling means responsive to said first signal pulse for enabling the generation of said ramp signal for a fixed period of time determined by the length of said first signal pulse whereby the amplitude of said ramp signal is determined by the time duration between the initiation of said first pulse and said second pulse, and means for measuring the amplitude of said ramp signal to thereby obtain the velocity of the golf club.
