Abstract

A golf swing training device includes a pad having a light-reactive material on one side of the pad, and an indicator having a light source capable of striking the light-reactive material on the pad and creating a visual representation of the light on the pad. The pad includes printed indicia on the light-reactive material in order to illustrate the proper alignment and path for a putting stroke. An individual can place a golf ball on the pad and attach the indicator to the putter, and perform a putting stroke to strike the golf ball on the pad. The movement path of the putter head over the pad is visually illustrated by the reaction of the light source with the light-reactive material such that the individual can compare the actual putting stroke indicated by the light source path on the pad to the printed proper path indicia for the putting stroke. The visual representation of the actual path fades in a short amount of time such that the individual can perform subsequent putting strokes in order to improve the correspondence between the actual putting stroke and the optimal stroke represented on the pad.
