  • Patent number: 5551924
    Abstract: A training apparatus that indicates the alignment of a practice golf stroke includes a base plate and a club member. The base plate includes a body, a pointer, a guide strip, and a warning background. The club member attaches to a golf club, and includes a mounting clip, an extension arm, and a colored translucent blade coupled together. The guide strip, warning background, and blade cooperate to indicate a first color when the practice stroke is aligned and a second color when the practice stroke is misaligned. The apparatus is configured such that a golf ball travels over the practice surface during use, and such that a user can clearly view the golf ball in the address position and as it is struck by the golf club.
