"In my 40 plus years of golfing having achieved Golf Digest Teacher of the Year, PGA Professional of the Year, and Horton Smith Award winner in my home state of Connecticut, I have seen a lot of putters - from its beautiful head to its awesome grip, you can't find a better putter than the Quantum."

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.

GOLF PUTTERS GOLF PUTTING TIP

"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?

GOLF PUTTERS GOLF PUTTING TESTIMONIAL

"I have no doubt the golf balls roll much smoother than they did with any of my former putters (Ping, Ping G5i Anser, Nike Oz, Taylormade Rossa Monza). My overall feeling is very positive - the Quantum Putter is very efficient and I really enjoy having it."

Edgar Zanotto, San Carlos Brazil

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."

GOLF PUTTERS GOLF PUTTING TESTIMONIAL

"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. I look forward to using my new Quantum Putter and I'll be happy to give you whatever help and advise I can from my experience as a golf club entrepreneur."

Quantum Conforms to USGA Rules

The United States Golf Association (USGA) governs the game of golf. Below is a summary and analysis of their rules as pertains to golf putter design; for official rules, please refer to the USGA website at www.usga.org.

GENERAL RULES -- A club is an implement designed to be used for striking the ball and generally comes in three forms: woods; irons; and putters.  A putter is a club with a loft angle not exceeding ten degrees designed primarily for use on the putting green.  The club must not be substantially different from the traditional and customary form and make. The Club must be composed of a shaft and a head. All parts of the club must be fixed so that the club is one unit, and it must have no external attachments except as otherwise permitted by the Rules.

ADJUSTABILITY RULES -- Putters may be designed to be adjustable for weight and some other forms of adjustability are also permitted. All methods of adjustment permitted by the Rules require that: 1) the adjustment cannot be readily made; 2) all adjustment parts are firmly fixed and there is no reasonable likelihood of them working loose during a round; and 3) all configurations of adjustment conform to the Rules. The disqualification penalty for purposely changing the playing characteristics of a club during a stipulated round applies to all clubs including a putter.

LENGTH RULES -- The overall length of the club must be at least 18 inches and except for putters must not exceed 48 inches.  For putters, the measurement of length is taken from the top of the grip along the axis of the shaft, or a straight line extension of it, to the sole of the club.

ALIGNMENT RULES -- When the club is in its normal address position the shaft must be so aligned that the projection of the straight part of the shaft on to the vertical plane through the toe and heel must diverge from the vertical by at least 10 degrees (translated, this means that the Lie Angle must be no more than 80 degrees or that the Declination Angle must be no less than 10 degrees).

SHAFT RULES -- The shaft must be straight from the top of the grip to a point not more than 5 inches above the sole. At any point along its length the shaft must: 1) bend in such a way that the deflection is the same regardless of how the shaft is rotated about its longitudinal axis, and 2) twist the same amount in both directions. The shaft of a putter head may be fixed at any point in the head.

GRIP RULES -- The grip consists of material added to the shaft to enable the player to obtain a firm hold. The grip must be straight and plain in form, must extend to the end of the shaft and must not be molded for any part of the hands. If no material is added, that portion of the shaft designed to be held by the player must be considered the grip. A putter grip may have a non-circular cross-section, provided the cross-section has no concavity, is symmetrical and remains generally similar throughout the length of the grip. A putter may have two grips provided that each is circular in cross-section, the axis of each coincides with the axis of the shaft, and they are separated by at least 1.5 inches.

CLUBHEAD RULES -- The clubhead must be generally plain in shape. All parts must be rigid, structural in nature and functional. It is not practicable to define plain in shape precisely and comprehensively but features which are added for the purpose of meeting dimensional specifications or for aiming or for any other purpose are deemed to be in breach of this requirement and therefore not permitted including: 1) holes through the head, 2) transparent material added for other than decorative or structural purposes; 3) appendages to the main body of the head such as knobs or plates or rods or fins. Exceptions to the plain in shape rule may be made for putters.  Any furrows in or runners on the sole must not extend into the face.  When the clubhead is in its normal address position, the dimensions of the head must be such that the distance from the heel to the toe is greater than the distance from the face to the back.  The clubhead must have only one striking face, except that a putter may have two such faces if their characteristics are the same, and they are opposite each other.

CLUB FACE RULES -- The material and construction of, or any treatment to, the face of clubhead must not have the effect at impact of a spring, or impart significantly more or less spin to the ball than a standard steel face, or have any other effect which would unduly influence the movement of the ball. The face of the club must be hard and rigid; some exceptions being made for putters. Except for acceptable markings the face of the club must be smooth and have no degree of concavity; acceptable markings include surface roughness that does not exceed that of decorative sandblasting or fine milling. Specifications with regard to roughness, material, markings in the impact area do not apply to putters.
