The lines on the upper surface of the putter head includes a first line perpendicular to the putting face, and a second line perpendicular to and centered about the first line. The length of the second line on the club corresponds to the diameter of the golf ball. In use, the first line on the club is aligned in the same plane as one equatorial marking on the ball, and the second line on the club head is aligned parallel to the second equatorial marking on the ball.
