Abstract
A golf club head includes a transparent cylinder with a sight on top and target on the bottom for indicating to the golfer when the club head is level and on line. An exemplary sight includes a centered disk surrounded by concentric rings; some rings being transparent. The target includes a larger central disk sounded by concentric rings of contrasting color or pattern. At the preferred club orientation, the center of the sight is vertically aligned with the center of the target and the vertical sight picture includes at least four concentric colored or patterned rings. In a second embodiment, the sight and target each include a swing stripe in the swing direction. The relative location of the sight and target centers and swing stripes show the golfer the position of the club head relative to the ball and aid in swing smoothness.
