Other equipment - allowed and prohibited
You may use equipment to help your play during a round, except that you 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 your 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 only concerns how you use equipment. It does not limit the equipment that you may have with you during a round.
