Abstract
A device for practicing the swing of a playing instrument such as a golf club is an elongated extension removably attached to the handle of the club to normally extend upwardly under the left arm pit to a level about the level of and behind the shoulders. The extension is lightweight of hollow plastic tubing and has a socket at the lower end which slides over the upper part of the club handle. A centering pin in the socket enters the vent hole, which is in the butt of most golf clubs, to guide and center the extension as the socket is removably clamped in place. As the golfer performs his back stroke, then his forward stroke, and then follows through in simulating striking the ball, the extension will indicate to him that he is stroking correctly. The extension is about the same length as a golf club to be carried in the golf bag when not in use. An arrow on the extension tells the golfer where to place his thumb. A projecting pin, on the extension, points to the ground when the extension is at the finish of the back swing.
