<p>A novel golf swing teaching aid golf club is provided herein. It includes a golf club which is simple in construction and is devoid of complicated mechanical, electrical or electronic gadgetry. The golf swing teaching aid golf club includes a golf club having a grip portion and a head portion, and a hollow cylindrical transparent shaft which is interposed between the grip portion and the head portion. The hollow cylindrical portion contains a predetermined volume of coloured, flowable, liquid of low viscosity. Such liquid is freely flowable, unimpeded, from one end of the hollow cylindrical transparent shaft portion adjacent to the grip portion to the other end thereof adjacent to 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 a first selected marker line to provide an easily-visible correct attitude of the golf club, when the golf ball is addressed. 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 further marker lines so as to provide an easily-visible indicator of the correct attitude of back swing, at golf ball impact and of follow through.</p> |
