Abstract: A flat plate-like base member is arranged to be seated on a supporting surface. An upstanding pedestal is mounted on the top surface of the base member and has a front surface from which at least one elongated straight rod has cantilevered support in a plane parallel with the base member. The rod is supported at a height whereby a golf ball on the supporting surface and a putter head can be located freely thereunder so that the putter head can be moved into contact with the ball. The rod is of a length whereby the putter head can be moved therealong through a putting stroke while the golfer sights down on the putter head and golf ball in relation to the rod whereby to encourage a straight line impact against the ball. The rod is constructed of at least two disconnectable parts and the top surface of the base has recesses for holding these rod parts as well as golf balls when the putting aid is not in use.
