Independent Claim
122 words
A device for use in a club swing training program comprising: a shaft; a body portion carrying a light and having therein a kerf that merges with a shaft-accommodating passageway so arranged that when said body portion is mounted to said shaft said light emits rays that are in a plane that is perpendicular to the axis of said shaft when held as a golf club at the address position; a mark on said shaft; and indicia on said body portion that are selectively alignable with said mark so that when said shaft is swung properly during said training program said rays fall along preselected paths which may be viewed to permit a close study of the phases of a club swing.
