Abstract: The head of a mallet-type putter includes on its upper surface indicia in the form of a first long line, a second short line, and a series of even shorter lines extending from the end of the short line and sweeping rearward in a curved are to become parallel with the first long line. In order to compensate for a golfer's sighting error resulting from eye predominance, the long line is arranged to align putts that are ten feet or longer in distance from the golf ball to the putting cup. The short line and the arcuate array of even shorter lines are arranged to align putts that are shorter than ten feet in distance from the golf ball to the putting cup. The golfer may measure the degree of eye dominance, if any, by a sighting method that closely approximates conditions found on all golf courses including a 4 1/4 inch putting cup, and this measurement is used to arrange the different sighting lines on the putter head.
