Abstract
Abstract A putter for use to improve skill in putting a golf ball is provided with a ball engaging head which presents a spherical face to engage the ball. This face has a reflecting mirror surface in which the user of the putter can see the image of a ball while he grasps the putter handle. Within the reflecting area, and positioned in the area of the reflecting surface visible to the user grasping the putter, there is an indicator mark contrasting with the mirror surface so as to be readily visible.
