Each side has a first terminus and a second terminus and a first end extends between the first terminus of each side. Moreover, the body includes an arcuate second end extending between the second terminus of each side, a circular target proximate the second arcuate end, an interior opening including a first interior end and a second interior end. Furthermore, the body includes an aiming member aimed at a center of the target. The aiming member includes a first aiming member side, a second aiming member side, an aiming member end and an elongated cut-out intermediate the first and second aiming member sides. The cut-out and the aiming member sides are parallel to the parallel sides and the cut-out extends through the body.

Abstract: An attachment tool for attaching an aiming device to a putter head is provided that includes a body. The body includes a flat face, a first side, and a second side. Moreover, the apparatus includes a pair of parallel arms integrally formed with the body that orthogonally extend away from the flat face of the body.

Abstract: A method for enhancing the accuracy of aiming while putting a golf ball with a putter is provided. A head of the putter includes a body having top and bottom surfaces separated by a distance, an interior opening extending part of the distance from the top surface to the bottom surface, a first end and a second end. The second end includes a target and the first end includes an aiming member extending into the opening and towards a center of the target. The method includes the steps of focusing on a pointed end of the aiming member and aligning the pointed end with a hole in the ground, executing a backswing while concentrating on moving the pointed end of the aiming member towards the center of the target, executing a forward swing towards the golf ball, and striking the golf ball to translate the golf ball along the alinement towards the hole.
