Claim:
A training device for training a golfer to use a putter of the type comprising an elongated shaft and a putter head attached to a bottom head of said shaft, where said putter head (a) comprises a striking face that (1) has a sweet spot and (2) is normally generally vertically oriented when said putter is held for use, and (b) has a top adjacent and above said striking surface, said training device comprising: (a) a housing having means for mounting said housing on said putter, (b) said housing including a laser fan generator for emitting a vertically oriented laser fan beam in a direction normal to said striking face of said putter head when said housing is mounted on said top of said putter head, (c) said laser fan beam being divergent enough in the vertical direction to project a line of light on (1) a golf ball placed in front of said striking face, (2) a target on the ground spaced away from said golf ball and said striking face, and (3) the ground between said golf ball and said target, such that said laser fan beam projects said line of light to connect said golf ball, said ground, and said target when said putter is held by said golfer in alignment with said golf ball and said target, (d) whereby a golfer can align said putter so that said line of light projected by said laser fan generator connects said golf ball and said target and can be aligned with said sweet spot of said putter head, so that said golfer will thereby hold said putter in a more optimum orientation.
