801.03 Artificial Devices
During a round, a player shall not use any artificial device that may directly assist in making a throw, except those devices that reduce or control abrasion to the skin (such as gloves, tape, bandages, or gauze) and medical items (such as knee or ankle braces). Placing an object as a directional aid is not allowed. An item such as a towel or a pad may be placed on the lie as long as it is not greater than one centimeter in thickness when compressed.
A device that is questioned by another player or an official is illegal unless it is subsequently approved by the Director.
A player shall receive two penalty throws, without a warning, if observed at any time during a round to be using an illegal artificial device. A player who repeatedly uses an illegal device may be subject to disqualification in accordance with Section 3.3 of the PDGA Competition Manual.
