Plumb-bobbing or ‘Plumb Bob Golf’ – it’s something you may have heard about golf, but you’re not entirely sure what it is. You’re in the right place!
Whether you’re a seasoned golfer or a curious enthusiast, our glossary aims to enhance your understanding of the game’s many nuances
Plumb Bob Golf | What is plumb-bobbing?
Plumb-bobbing is simply a green reading technique used by the likes of JB Holmes, Rickie Fowler and also by one of the best putters the game has seen, Ben Crenshaw.
How would you use plumb-bobbing during a round?
It’s a pretty simple technique which involves a player using the shaft of the putter and their ball to help read a putt.
The technique is mainly used on putts where there isn’t an obvious slope and it determines which side of the ball is higher, effectively telling you which way the putt will break.
To plumb-bob correctly:
- Crouch between 5 and 15 feet behind the ball but for longer putts, you may want to stand upright
- Hold the putter just below the grip with the club head just off the ground
- The shaft should form a straight line from the ball at the bottom of the shaft to the hole (top of the shaft)
- Looking through one eye with the other eye closed
- Note whether the green is higher on one side of the shaft
- Whichever side is the high side, the ball will break in the opposite direction
- For example, if the high side is to the left, the putt will break right
- You may also notice that the hole tilts in one direction.
Why has plumb-blobbing caused controversy?
JB Holmes was criticised for using the technique on every putt at the 2019 Genesis Open. There were examples where Holmes used plumb-bobbing on 18 inch putts when in theory he could simply tap the ball in.
Despite the fact there wasn’t anything in the Rules of Golf to punish slow play, people believed the American should have received a penalty, mainly due to his overuse of the method.
That has recently changed, and now there are rules in place to make sure pace of play. Rule 5.6 now states: “A player must not unreasonably delay play, either when playing a hole or between two holes.”
