If it doesn't work for you, or if the results aren't worth the effort, that's fine. Another is that the club head weighting on a lot of putters affects their ability to hang with the shaft perfectly vertical.įor people who understand the geometry and understand the limitations in the practice, the physical laws are what they are, and they can be used to help determine the relationship in contour between two different parts of the green. The biggest is the one that most people don't even umb bobbing assumes that the relationship between the contours between where you're standing and the hole remain constant the entire distance between you and the hole, and of course, that's seldom the case. I admit, there are a lot of issues with the practice. He may know a bit about putting, but he doesn't seem to understand geometry very well.
So, what if anything is useful and accurate from plumb bobbing? Plumb bobbing strikes people as effective because it confirms the subconscious read of slope (not break), which depends upon posture and sighting-alignment biases, and because in these cases it seems seldom to hurt the putt. In other words, if your body-head-eye axis is vertical to gravity, sighting along a shaft that is also vertical to gravity ALWAYS aligns the ball and hole UNLESS YOUR DIRECTION OF GAZE IS OFF TO START WITH. The only difference is the direction of your gaze. Where'd the break go? The shaft is vertical, your head and eye position relative to the shaft are the same, but the plumb bobbing's "apparent" slope has disappeared. If you don't believe this, then the next time you plumb bob a putt with obvious slope and get your standard hole-to-the-side alignment, glide your head laterally a bit behind the shaft until the ball and hole are perfectly aligned. If you actually aim the gaze along the true line from ball to hole, the shaft will always align both the ball and the hole, regardless of slope and regardless of posture.
It's just a matter of the direction you aim your dominant eye's gaze. It's not possible to construct a scenario of ball, green contour, and hole in which one cannot position the head and eye so that the ball and hole align along a vertically suspended putter shaft. Why doesn't the shaft align with both the ball and the hole, regardless of the slope? Well, the short answer is that it does! Every single time.
It's a mental ploy used to reinforce what your mind - conscious or sub - has already determined. There's no logical, physical, or geometric way that plumb bobbing makes any sense at all. Shift your head to the other side and the putt will magically "appear" to break the other way. If you stand to the side of the line - or move your eye to one side of the line or the other - then the putter can be made to go through only one of them.īut that doesn't prove which way a putt breaks. Basic geometry tells us that we can create a line from two points, and if you stand directly on that line, holding a putter vertical will connect those two points. There are only two reference points: the ball and your hole. Plumb-bobbing is intended as a use of a reference point to determine the
