Abstract: A golf putting training device for improving putting strokes comprising, in combination, a conventional golf putter having a shaft and a putter head, a slider connectible to the putter head and being adapted to be used in connection with a pair of elongated guide elements. The guide elements being disposed in horizontal, spaced parallelism, and coacting with the slider in tongue-in-groove fashion. The slider and putter head being translated along the length of the guide elements and substantially perpendicular thereto, whereby the putter head approaches and strikes a golf ball positioned proximate an end of the guide elements and intermediate them. The guide elements being adapted to cooperate with the slider so that the longitudinal axis of the putter head is maintained substantially horizontal and perpendicular to a desired path of putter head travel.
