A shaft has upper and lower ends and an intermediate extent. A putter head simulator includes a horizontal lower plate having upper and lower surfaces, a mirror attached to the upper surface of the lower plate, and a vertical coupling plate extending upwardly from the upper surface of the lower plate. An angular adjustment assembly is for varying the angular relationship between the shaft and the simulator. A shaft length adjusting assembly is for varying the length of the shaft.
