  • Patent number: 5580058
    Abstract: A golf putter composed of transparent or translucent material with a raised opaque central portion and a clear heel and toe. The width of the central portion approximates the diameter of a golf ball. The distance from the ball striking surface to the heel and toe weights is considerable, it is greater than the radius of a golf ball. The weights are placed far enough behind the ball striking surface to be outside the focused area. When the golfer aligns the putter with the ball, the putter head appears to be a single line with a width approximately equal to the diameter of a golf ball and a depth greater than the radius of a golf ball. The clear heel and toe provide maximum contrast to the central portion, enabling the golfer to maintain focus on the center of the head throughout the stroke. This improves the golfer's ability to visualize the movement of the putter relative to the "target line".
