Abstract (en)
[origin: WO2005102467A1] A golf putter head (1) has a base (2), a cover surface (3), a hitting surface (4), a receptacle (5) for a shaft and an optical positioning system (6). The optical positioning system (6) comprises at least two marks (9, 7, 12, 15) sighted with one eye by the golf player, who moves his head until the marks (9, 7, 12, 15) sighted by his eye optically overlap and his head is in the correct position. The sum of the distance (A) between the central point (10) of the marks (9, 7, 12, 15) of the positioning system (6) and the radius (R) of a golf ball (11) and of the distance (Y) between the golf ball and the hitting surface (4) in the address position essentially corresponds to the average distance (X) between the eyes of a person.
