Golf is open to all
Setting down object to help with aiming, taking stance or swinging
You must not set an object down to help with aiming or to help in taking a stance for the stroke to be made (such as a club set down on the ground to show where you should aim or position your feet).
“Set an object down” means that the object is in contact with the ground and you are not touching the object.
If you breach this Rule, you cannot avoid penalty by removing the object before you make your stroke.
This Rule also applies to taking an action for a similar purpose, such as you putting a mark in sand or dew to help with your swing.
