Abstract
Abstract A practice device for use by golfers to improve their putting ability comprising a putter club having a grip portion, a shaft portion and a head portion with a putting face, and a target adapted to be positioned at a distance from the user, the club comprising a source of high intensity light housed in the grip portion, optical fibers for conducting light from the source to the putting face, and a lens enabling light from the source to be projected from the face of the club as a narrow beam of high intensity light in a direction perpendicular to the face, with the target comprising reflective device for indicating the point at which a projected light beam contacts the target, and including a plurality of parallel, vertically arranged side-by-side reflective strips, so that light projected from the club contacts the target in such a manner as to be visible to the user to indicate his point of aim.
