Abstract: A training method for achieving a repeatable putting stroke incorporates an elongated rod affixed to a shaft of a putter. The putter head displaced from the ball while keeping a separation distance between the elongated rod and a plane passing through the ball. By repeating straight back and straight forward stroking of the ball while maintaining the separation distance, a repeatable putting stroke is achieved. Once achieved, the elongated rod is removed from the putter shaft for repeating the straight back and straight forward stroke developed from the feel using the elongated rod. Attachment rod is provided in an alternate embodiment for aligning the elongated rod perpendicular to the putter face. Indicia are placed on the elongated rod for providing a measurement of a displacement distance between the putter head and the ball during the straight back stroking portion. With such a device and training method, repeatable putting stroke is achieved.
