TEST YOUR PUTTER FOR SWEET IMPACT CAPABILITY

TAP TEST
Hold your putter loosely with one hand and then tap where on the head where you are supposed to strike the ball – if this tapping causes the putter head to rotate even the slightest, then your putter has no sweet spot and is not capable of sweet impact dynamics.

SPIN TEST
Hold your putter between the palms of your hands and then move your palms to and fro to cause the putter head to spin one way then the other – if this spinning wobbles even in the slightest, you’re your putter is out of balance and incapable of sweet impact.

"I came across your website and have been reading it for over an hour and I am blown away! You give the best explanation about putters and putting I have ever read and that's saying something because I have been a PGA member for over 50 years and active in teaching putting almost that entire time. Quantum is the only putter that has it right."

Later he writes, "There is no question in my mind that the science that has gone into this putter is of the highest order. High on the list are the training alignment aids that go with this putter, they are extremely valuable, plus you have the opportunity to change the weights in the head, if you so desire. To say the least, I am very impressed with my new Quantum Putter.

SWEET IMPACT FOR DUMMYS Yes we know it should be "Dummies", but let's not complicate things here. Here we want to convey the very technical concept of Sweet Impact to those who don't want to bother thinking too hard about it.
	If you wouldn't play tennis with a racquet that looked like this...
... then why would you play golf with a putter that looked like this?
	If you wouldn't play baseball with a bat like this...
...then why would you play golf with a putter that looked like this?
	If you wouldn't play billiards with a cue that looked like this...
... then why would you play golf with a putter that looked like this?

QUANTUM GOLF PUTTING PUTTERS TESTIMONIAL

"The Quantum is so different than anything else that comparing it to other putters is like trying to compare apples and oranges. My major concern about the Quantum was its negative loft because so many were telling me that a loft was needed to lift the ball up out of a turf indent; but that was quickly dispelled and to prove the point to myself, I actually stepped on a few balls to push them further down into the green and I found that the rolling launch still always occurred."

"I was the inventor of MetalWoods and ever since I sold my company to TaylorMade, I have always said that if I were to go back into the business it would be with a putter rather than the other clubs in a full set. I understand perfectly what you said about bending/breaking the shaft, and your analogy about heel shafting tennis racquets made the point about how ridiculous it is to heel shaft putters.

Physics of Putt Impact

Here is how to make a quantum improvement in your Putt Impact. There are four aspects to the Golf Putt: Stoke, Glide, Impact, Launch. Here we will cover the topic of Putt Impact, but before we get started, let's make sure we have common understanding of that term.

Impact is the point at which energy is transmitted from the moving putter head to the stationary ball, thus causing the ball to be launched. Good impact is hard to explain without getting overly technical; suffice it to say that it is what tennis players mean when they say "sweet impact" or "hitting the sweet spot".

Technology and Technique effect Impact; we will cover the Technology of Impact here and leave Technique for later; but put your thinking cap on because this is going to get technical.

There are three requirements for Sweet Impact Dynamics: 1)The Power Vector (putter shaft) must be perfectly straight. 2)The Power Vector must be aligned such that it intersects into the center of gravity of the putter head. 3)The putter must be stroked such that the center of gravity of the impacting object (putter head) impacts the center of gravity of the impacted object (ball) along the plane of movement of the power vector (putter shaft). Sweet Impact Dynamics is destroyed if any one of these requirements is botched.

During our research, we found that every currently existing putter has shortcomings which adversely effect impact. Many have bent shafts or broken "Anser" styled shafts which violate the first requirement. Many have heel shafting which violates the second requirement. Many are "face balanced" (which actually means they are shafted such that they are unbalanced toward the face) which violates the third requirement. Others are "toe/heel balanced" (this actually means they are shafted such that they are unbalanced toward the toe/heel) which also violates the third requirement. To our astonishment, we could not find a single putter currently on the market which met all three requirements for Sweet Impact Dynamics. Of course, without sweet impact dynamics, precision putting is impossible.

Some putter makers try to minimize shaft vibration by incorporating a soft striking pad onto the face of their putter, mistakenly thinking that the vibration is caused by the impact itself. A soft striking pad only dampens impact somewhat which lessens launch power which causes a putting shortfall; obviously this putting shortfall must be overcome by applying more power, which in-turn overcomes the dampening of the impact caused by a soft striking pad - so where are we?... right back to where we started. The only way to overcome shaft vibration is with a straight shaft. So if a golfer wants a satisfying "thud" instead of an annoying "ping", he needs to use a putter with a straight shaft.

Some putter makers try to minimize the impact torque caused by misaligned heel shafting with "high moment of inertia". Most ordinary people don't really know what inertia really is much less do they know what moment of inertia really is, so lets pause a moment to learn exactly what these terms mean before moving on with this topic.

Inertia is a scientific term which describes the following fundamental property of matter: An object at rest tends to remain at rest unless a force is applied to make it move; likewise an object that is moving tends to continue moving at its current pace unless a force is applied to make it move less or move more. This resistance to any change in movement is called "Inertia".

Moment of Inertia is a scientific term which describes the following fundamental property of matter: An object at rest tends to remain at rest unless a torque is applied to make it rotate; likewise an object that is rotating tends to continue to rotate at its current pace unless a torque is applied to make it rotate less or rotate more. This resistance to any change in rotation is called "Moment of Inertia".

Torque is a force which is applied to an object offset of the object's Center of Gravity, thus causing rotation of the object about it's center of gravity.

Okay, now that we know what we are talking about, let's continue. Misaligned shafting (shafting that is not aligned perfectly with the head's center of gravity) will upon impact with the ball always generate an offset force (torque) which opens the club face at the worst possible time - ball launch. Yes, this adverse torque is resisted by the head's Moment of Inertia and so by increasing the Moment of Inertia of the head, this adverse torque can be lessened. But lessening a problem does not solve the problem. The only solution to this problem is to eliminate impact torque and that can only be done by properly aligned shafting.

Why is Sweet Impact Dynamics so important?

With Sweet Impact Dynamics, you will feel that satisfying "thud" of a solid hit, a feeling seldom felt by golfers because of the prevalence of heel shafting and the popularity bent/broken shafts. There are two simple tests you can perform on your own putter to find out if it is capable of sweet impact dynamics (SEE LEFT SIDEBAR). If your putter fails either of these tests, then you have a putter which incapable of Sweet Impact Dynamics -- a putter which is actually designed to help you miss your putts!

Technology of Sweet Impact Dynamics

Heel Shafting destroys sweet impact dynamics because at impact the striking face of the putter head is torqued open by the offset transfer of energy at impact. That causes the launch to veer off intended direction and it also imparts an adverse lateral spin upon the ball which causes the ball to veer off its intended path. Some putter makers tout "high moment of inertia" as the solution to this torque problem, but while it helps a little, it does not really solve the problem. The solution to the problem is to eliminate the adverse torque entirely by perfectly aligned shafting with a perfectly straight shaft.

Bent/Broken Style Shafts also destroy sweet impact dynamics because at impact the rebound energy that must be absorbed by the putter needs to be transferred up the shaft to the golfers hands. If the shaft is not perfectly straight, this transfer of energy will cause a vibration of the shaft. This is not a big problem so it will go unnoticed until the golfer learns how good it feels not to have this vibration.

It is important to bring this understanding home especially when most people tend to glaze over technically difficult subjects such as we are discussing. Sometimes, the points can be brought home the best with silly but effective cartoon comparisons (SEE LEFT SIDEBAR ENTITLED, "SWEET IMPACT FOR DUMMYS").

Because of the long tradition of heel shafting which makes sweet impact dynamics impossible, golfers don't know how good sweet impact feels -- every golfing stroke has to be adjusted for the torque caused by heel shafting and golfers have had to become accustomed to the annoying vibration that "sour impact dynamics" sends up the shaft. Because of USGA Rules there can never be any relief for this problem in drivers, but because there is an exception to the USGA Rules for putters, a putter can be designed which is actually capable of "sweet impact dynamics". This is huge! This is what we have done so now finally golfers can actually enjoy the great feel and improved performance of sweet impact at least when putting -- all they need is the new technology Quantum Putter. Our research found no other putter currently on the market which is designed for Sweet Impact, so there is no comparison; the Quantum is your only choice for this extremely important benefit.
