Abstract: A simulator enabling a golfer to practice his putting skills and at the same time become more aware of the optimum motion of his shoulders and arms during a putting effort. This simulator comprises an elongate guide plane of flexible material having a mid portion as well as end portions, and also having an active edge, along which a lower portion of the shaft of a putter may pass during efforts by the golfer to putt a golf ball into a nearby cup. Components are used for supporting the guide plane in a desired relationship to a playing surface, such components being heightwise adjustable, so as to enable the individual heights of the mid and end portions of the guide plane above the playing surface to be independently adjusted, which at the same time determines the positioning of the active edge with respect to the playing surface.
