"Equipment" is anything used, worn or carried by or for the player except any ball he has played at the hole being played and any small object, such as a coin or a tee, when used to mark the position of a ball or the extent of an area in which a ball is to be dropped. Equipment includes a golf cart, whether or not motorized. If such a cart is shared by more than one player, its status under the Rules is the same as that of a caddie employed by more than one player. See "Caddie."
