The golf teaching aid includes a golf club having a grip portion and a head portion, and a hollow cylindrical transparent shaft interposed between the grip portion and the head portion. The hollow cylindrical portion contains a predetermined volume of colored flowable liquid of low viscosity. Such liquid is freely flowable, unimpeded, from one end of the hollow cylindrical transparent shaft portion adjacent the grip portion to the other end thereof adjacent the head portion to check the correctness of the swing of a golfer. Before the golf swing, the liquid adopts a position within the hollow cylindrical transparent shaft at selected marker lines. Under the influence of centrifugal force during the golf stroke, the liquid thereby adopts different locations within the hollow cylindrical transparent shaft during the golf swing, at selected marker lines, so as to provide the golfer with an easily visible indicator of the correct attitude of back swing, at golf ball impact and of followthrough.</p> |
