Abstract
Abstract A video device and method for analyzing golf club swings or the like includes means for detecting the golf club swing and calculating the resultant velocity of the club head. The velocity is then displayed on a display device in either a digital or analog mode. The golf club swing can then be analyzed by comparing the relative velocities during different club swings.
