Abstract
The present invention provides for a "rifle sighting system" on the top surface of the clubhead which allows the golfer at the address position to align the ball where the center marker on the clubface will be at impact. This system factors in the effect the downward bowing of the shaft on the forward swing has on the center of the clubface's position at impact. It also factors in the parallax visual error the golfer experiences as he tries to align the center of the clubface to the ball.

7384345 - Golf putter with rotary disc alignment aid

A putter head (1) is described wherein the putter head (1) has a putter face (4) and a linear marking (9) located on an upper surface (44) of the putter head (1). The relative angle of the putter face (4) with respect to the linear marking (9) is adjustable in order to compensate for inherent inaccuracies in a player's visual judgement when putting. In a preferred embodiment, the upper surface (44) is in the form of a rotatable disc (3) wherein the rotatable disc (3) is moveable about an axis in order to selectively adjust the relative angle between the linear marking (9) and the putter face (4).
