44 Rule 4 (2) When Another Ball May Be Substituted. The player may substitute another ball only if it can be clearly seen that the original ball is cut or cracked and this damage happened during the hole being played – but not if it is only scratched or scraped or its paint is only damaged or discoloured. • If the original ball is cut or cracked, the player must replace either another ball or the original ball on the original spot (see Rule 14.2). • If the original ball is not cut or cracked, the player must replace it on its original spot (see Rule 14.2). If a player makes a stroke at an incorrectly substituted ball, the player gets one penalty stroke under Rule 6.3b. Nothing in this Rule prohibits a player from substituting another ball under any other Rule or changing balls between two holes. Penalty for Playing Ball from a Wrong Place in Breach of Rule 4.2c: General Penalty Under 14.7a. 4.3 Use of Equipment Rule 4.3 applies to all types of equipment that a player might use during a round, except that the requirement to play with conforming clubs and balls is covered by Rules 4.1 and 4.2, not by this Rule. This Rule only concerns how equipment is used. It does not limit the equipment that a player may have with them during a round. 4.3a Allowed and Prohibited Uses of Equipment A player may use equipment to help their play during a round, except that a player must not create a potential advantage by: • Using equipment (other than a club or a ball) that artificially eliminates or reduces the need for a skill or judgment that is essential to the challenge of the game, or • Using equipment (including a club or a ball) in an abnormal way in making a stroke. “Abnormal way” means a way that is fundamentally different than its intended use and is not normally recognized as part of playing the game. This Rule does not affect the application of any other Rule that limits actions a player is allowed to take with a club, ball or other equipment (such as setting down a club or other object to help the player in aiming, see Rule 10.2b(3)).
