Abstract: A golf practice aid which uses a pressure-sensitive double-sided tape for removably attaching the aid to the club face of prior art club without noticeably changing the characteristics of the club. The practice aid preferably includes a metal base, which at its center has a circular ball striking platform which is raised from the base by means of a beveled edge and, at each end thereof, a raised, linear, triangular, alignment rail. When properly stroked with the club, the ball hits on the circular striking platform thereby causing the golf ball to go in a straight line in the direction of the target. When the golf ball is improperly stroked it strikes on the beveled edge surface and is turned away from the target.

Abstract: The device comprises a body having a well which receives a damping fluid and a weight in the form of a lead or steel ball. The body has a groove which extends around the entire periphery of the body so as to receive the strings of a sports racquet. The groove and the well are oriented such that the well extends perpendicular to the plane of the racquet head when the groove entraps the strings of a racquet.
