Abstract
A golf putter having an alignment aid for aligning the player's head relative to the ball and the putter head. In addition to providing alignment along the usual X and Y axes, the alignment aid of the invention allows precise and repeatable head positioning in the fourth and fifth axes as well. A pair of vertically-aligned pins protrude from a back surface of the putter head, substantially perpendicular to the putting face of the club. The diameter of the upper pin is less than the diameter of the lower pin. In addition, the length of the upper pin may be slightly shorter that the length of the lower pin. Typically, the pins are made in contrasting colors such as black and white. In operation, a golfer sights down at the pins and establishes a uniform border of the lower pin visible around the upper pin.
