| 摘要 |
A partially or totally transparent golf putter head (47) may be manufactured using glass or clear polymer material. The putter head (47) may have suitably positioned lines and markings (also called positioning and aiming matrices), such as crosshairs (50), as part of a parallax positioning system. The putter head (47) may also comprise a integral 45-degree prism (43) for reflecting an image of a ball (50) to a user, allowing lines or logos (50, 52) on the ball and putter head to be aligned for aiming purposes. The putter head (47) may be selectively sandblasted, beadblasted or machined; may have rounded cut outs at the rear for retrieval of balls; and may have a plastic or fibre covering on the bottom surface. |
