ABSTRACT:
A golf putter has a head and shaft, with the head having a bottom formed with a recess and a narrow annular peripheral bottom flat face extending from the recess, which flat face contacts the putting surface. The golfer, by tactile means, senses the limited surface face portion contact with the putting surface and whether the head is correctly anchored flat parallel to the putting surface. If necessary, the golfer adjusts the putter head to be flat parallel to the putting surface. The golfer consistently perceives if and when the putter head is correctly level with the plane of the putting surface. The back portion of the head is provided with vertically displaced alignment elements. The golfer, after the annular flat bottom face is correctly anchored, then by eye aligns the alignment elements. The combination of the correct level anchoring of the putter head followed by the correct eye alignment of the alignment elements ensures that the golfer's head is correctly positioned behind the ball and in true alignment for putting. The alignment elements are an upper T-shaped cut-out and a lower precision matched and colored T-shaped insert. The golfer's eye matches the insert fully within the cut-out and in doing so confirms correct golfer head alignment directly over the true target line of the ball.
