I adjusted my club's settings during the round, can I still use it?
No, you cannot use the club if you deliberately changed its settings during the round — unless you restore it to the original position before making another stroke. If you do use it without resetting it, the penalty is disqualification.
What counts as deliberately changing the club
Rule 4.1a(3) says you must not make a stroke with a club whose playing characteristics you deliberately changed during the round. That includes using an adjustable feature — like twisting a hosel to change loft or lie, moving a weight port, or flipping a face-angle setting — or physically altering the club in any way. It also covers applying any substance to the clubhead (other than cleaning it) to affect performance. Normal wear from strokes, practice swings, or taking clubs in and out of the bag does not count; that club stays conforming.
The one way to fix it and keep playing
The Exception lets you avoid the penalty entirely. If you changed the club using an adjustable feature, you can restore it as nearly as possible to its original position before you use it to make a stroke. Adjust the feature back to where it was at the start of the round. Do that before your next swing with that club, and there is no penalty — the club is treated as conforming and you can keep using it. The same applies if you had a non-permissible external attachment (like a sticker on the face) and you remove it before the next stroke.
What happens if you don't reset it
If you make a stroke with the club after deliberately changing its settings and you haven't restored it to the original position, you are disqualified. There is no two-stroke penalty option here — the breach is disqualification. The club is treated as non-conforming for that stroke, and Rule 4.1a(1) makes the penalty DQ. This applies even if the change didn't actually help you on that particular shot.
Exceptions that change the answer
- You changed the club using an adjustable feature and restore it to its original position before making another stroke → No penalty; the club may be used
- You had a non-permissible external attachment (e.g., a sticker on the clubface) and remove it before making another stroke → No penalty; the club may be used
Frequently asked questions
I accidentally bumped my driver's weight setting when putting it in my bag — is that a penalty?
No. Accidental changes are not "deliberate" under Rule 4.1a(3). If the setting moved on its own or through normal handling, the club remains conforming and you can keep using it.
Can I change my driver's loft between holes if I change it back before the next tee shot?
Yes, but only if you restore it to the exact original setting before making a stroke with it. The Exception requires the club be returned "as nearly as possible to its original position" before the next stroke. Doing it between holes is fine as long as it's reset before you swing.
What if I realize I changed the setting three holes ago and have already hit shots with it?
You are disqualified. The penalty applies the moment you make a stroke with the deliberately altered club. You cannot go back and fix it retroactively — the breach has already occurred.
Does this rule apply to adjustable putters too?
Yes. Rule 4.1a(3) covers all clubs. If you deliberately adjust a putter's loft, lie, or weight during the round and don't restore it before your next stroke, the penalty is disqualification.
My playing partner adjusted my club without my knowledge — am I penalized?
Only if you knew about it and made a stroke anyway. The rule requires that you deliberately changed the club's characteristics. If someone else changed it without your awareness, you haven't breached Rule 4.1a(3).
