Abstract (en)
[origin: WO8605700A1] A golf ball having on its spherical surface at least four minute marks, which a player is to look at when he hits the ball, these marks being distributed on the same spherical surface so that at least one of the marks can be seen at a distance from any direction. Preferably a total of six marks are put on the spherical surface of a golf ball so that the marks are in such points thereon that correspond to the intersections of three circular bisectors of the ball which cross one another at right angles.
