Abstract: A detachable training system for golf clubs includes a golf club head having a top portion and a face portion. The system includes a removable training device with a base, the base formed to fit in a receiver on the club head. The system also includes a first removable plate formed to fit in the receiver on the club head when the removable training device is removed. In use, the removable training device is installed on the club during practice and is removed during actual golf rounds. The removable plate is installed on the club during golf rounds to provide similar weight, use and feel of the club head so the golfer can accurately replicate the strokes perfected during practice.

Abstract: A golf putter with a novel head design consists of solid materials laminated horizontally to yield a single surface alignment aid on the surface that strikes the golf ball (the front face/face). Optional alignment markings on the top surface of the putter, centered over the point on the face where there in minimal torque when the head strikes the golf ball ("sweet spot"), combine with the single surface alignment aid on the face to form a single surface two-dimensional alignment system. The resilient nature of the solid materials used for the preferred embodiment of this putter head imparts a softer "feel" to the golfer, reduces skid of the ball after the ball is struck, and produces a light-weight club, allowing the golfer to use a fuller complete stroke for each putt, thereby improving precision and accuracy from putt to putt.

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.
