First of all, thank you for having the courage to be an early adopter - we love you! But if you bought an earlier model Quantum Putter that has now been deemed (either by our standards or yours) to be not good enough, then please simply return it under our Satisfaction Guarantee Policy, and we will give your money back, or credit you on the purchase of a new QUANTUM GOLF PUTTER, a putter we can assure will be not only good enough, but the best in every respect.
Engdahl is a Physicist who served his country during the Vietnam and Cold War Era as a Principle Design Engineer designing and engineering state-of-the-art weapons systems for the US Department of Defense. Specifically these tools that were used by Naval Aviators for the purpose of hunting and killing enemy submarines. In doing this for nearly twenty years, he became an expert in designing tools that were natural in usage, and effective in purpose.
Engdahl is an Entrepreneur who after retiring from weapons development for DOD in 1980 at the age of forty (40), started a Computer Company to provide low cost (at that time) computer systems and management information system software to American businesses. This was at the very beginning of the microcomputer revolution and a very exciting time. After a good run, he sold the technology he developed in 2000, and used the money to begin a new career as a builder.
Engdahl's father was a builder. Duane worked as a builder in his father's business from an early age. By the time he went off to college, the younger had become a journeyman in almost every building trade, and the elder was very disappointed that he did not take over the family business. But after a good run in the high pressure cooker of state of art military weapons systems and business computer development, at almost sixty years of age he was ready to return to his first love -- Building.
Engdahl started again at the bottom of the building business. He worked at minimum wage as a "stick holder" for a land surveyor, then he became a surveyor, then a civil engineer, then a building designer and site planner, and finally a Registered General Contractor. He started his Contracting Business in 1997, and this was the busiest and most rewarding time so far in his life. There is nothing quite like designing and building beautiful enduring things.
But after seven years of working long hard hours, even busy and rewarding times get tiring' so Engdahl sold his Building Business and directed his attention to a problem that had been bugging him since he began golfing back in college -- the incredibly defective design of the golf putters. The problem was an easy one to fix, so he didn't expect it would take too long. It turned out to be more difficult than he expected due to the constraints put on club design by the Rules of Golf. Finally, after fifteen years of serious Research & Development and seven versions, the final design of the QUANTUM GOLF PUTTER is now available for golfers to buy and enjoy.
The third version was a putter designed more like a traditional golf putter. It would convert from a play putter to a practice putter so we dubbed it the "Convertible". It had a head lie angle that could be ordered within the range allowed by the USGA (no more upright than 80 degrees)' and at any lie angle. the putter had polar symmetry that enabled sweet impact. The ends were be rounded over so there was be no possibility that the putter could be used with an end impact. Many practice features were embodied into this putter including weight adjustment, loft alignment aid, lie alignment aid, and sweet spot impact aid. Plus we invented an ingenious way to make the conversion from play mode to practice mode (and back to play again) conveniently -- all the golfer had to do is pull the head slightly downward from the shaft and it would release to allow turning 180 degrees into the other mode; then when released, it would spring back and remain securely in that mode until converted back later.This was a very costly embodiment that was unique, so we went to the expense of patenting it. But once again the USGA once again deemed the Convertible non-conforming with the Rules of Golf, because it was too easy to convert from a practice putter to a play putter and back again. We could not market a non-conforming putter, so the Convertible had to be scrapped and another version had to be designed.
Our goal was to make the best possible golf putter. Other putter makers make many putter models: Ping for example, makes at last count about 60 golf putters. Odyssey about 40, Taylormade about 20, and Titleist about 10. Quantum on the other hand makes only 1 golf putter. Why, because we believe that there can be only one (1) "Best of Anything", and we make that one best golf putter. After fifteen years (15) of serious Research and Development, we have finally achieved that goal with the QUANTUM GOLF PUTTER; and it is now available for you to buy and enjoy.
What we learned was that the Conforming Convertible was too complicated for most golfers. And because of all its practice aids golfers perceived it to be practice putter more-so than a play putter, and that was not our intention. So we developed a simplified golf putter that eliminated the practice play features but kept the conforming form factor and we dubbed it the "Simplicity". The Simplicity was made of Aluminum instead of Brass because we learned from the early adopters that they disliked the tarnish and lack of endurance of Brass. So we created a new website to see how well it was received by the golfers. Sad to say, not very well' because Aluminum was not sufficiently massive to make a good golf putter.
The second version was a putter designed to strike the ball on the front or back face, so we dubbed it the "Two Face" putter. Completed in 2004, it was ambidextrous, had polar symmetry, and one side was flat at the sweet spot and intended for play; while the other end was rounded at the sweet spot and was intended for practice. Its sole was at an 80 degree angle to the shaft on each side, so we thought that would abide the Lie Angle Rule. It seemed like a very good and simple solution to the putter problem. But the governing body of golf (USGA) again deemed the Two Face non-conforming with the Rules of Golf -- they thought the putter could be used like a croquet mallet and did not think we did enough to prevent that. Since the ends were still somewhat flat, they were concerned that the putter could still be used for striking the ball on the ends of the putter, instead of on the sides. So the Two Face had to be scrapped and another version had to be designed.
Our extensive field testing of golf putters over the years has revealed that it is best to roll the ball on the green on shorter easier putts, but it is better to loft the ball up into the air for first part of the distance on longer more difficult putts. The reason being that less can go wrong while flying through the air, but more can go wrong when bouncing back onto the green. The tipping point for this decision is about 30 feet. So on putts less than about 30 feet, a rolling putter would be best; but on putts greater than that, a lofting putter would be best. The Quantum Putter is designed to be a rolling putter. Other putters on the market today typically have loft of about 5 degrees, but that is insufficient for long putts, and excessive for short putts. Ideally, a golfer should have two putters in the bag: A rolling putter with a zero loft for short putts, and a lofting putter with 10 degrees loft for long putts. Both putters should have exactly the same form factor, so there is consistency of putting "feel". Currently at Quantum, we make the best "rolling putter", but we do not yet make the "companion lofting putter". That is our next product in R&D. The Quantum Lofter will be ready for release to the golfing market in the first quarter of 2018. It will have exactly the same form factor as our Roller except it will have a 10 degree loft instead of a zero loft. However it will only be available to our Quantum Roller Clients.
What we learned from the early adopters was that the Simplicity head was not massive enough. So we developed a similar golf putter that was made more massive by increasing the front to back dimension, and filling the shaft with very massive Tungsten flakes (at this time several club makers were experimenting with shaft weighting too). We dubbed this new putter the "Finesse" and we created a new website to see how well it would be received by golfers. Sad to say, not very well. Why? Because Aluminum (even when dimension is increased) is still not massive enough for precision putting, and weighting the shaft is counterproductive to a good putting stroke.
The first version was a stubby looking mallet that looked much like a croquet mallet, so we dubbed it the "Stubby" and completed in 2003. It was ambidextrous, had polar symmetry, and one end was flat and intended for play, while the other end was rounded and intended for practice. Its sole was round so it could lie on the green at any angle. It seemed like a very good and simple solution to the silly putter problem. But the governing body of golf (USGA) deemed the Stubby to be non-conforming with the Rules of Golf -- they did not feel it was traditional for the ball to be impacted on the ends of the putter instead of the face, nor did they feel it should be possible for a golfer to use a putter with a shaft angle more upright than 80 degrees.So, the Stubby had to be scrapped and another version had to be designed.
The forth version was a putter designed just like the Convertible except the conversion from practice mode to play mode was made difficult' so we dubbed it the "Conforming Convertible". The USGA deemed the Conforming Convertible conforming with the Rules of Golf. So finally, we are able to market a new prototype golf putter to the early adopters. We named our new golf putter the Quantum Golf Putter because it would make a quantum improvement in golf putting performance' and we created a website to market it over the World Wide Web to learn how well it was received by the entire market of golfers.
We learned much from the shortcomings of the Finesse. So we developed a similar golf putter that was made of Stainless Steel which is almost as massive as Brass but far more durable. We rejected the idea of weighted shafts, thinking that logically the head is the business end of the putter, not the shaft or grip. And we dubbed this new putter the "Roller". Why? Because both laboratory and field testing had by now demonstrated that our new golf putter technology was superior in launching the ball on the green with immediate topspin roll -- that of course is what every golfer wants.
Back in 2002, our Founder Duane Engdahl got "the big idea" that golf putters must embody Polar Symmetry in order to be capable of Sweet Impact. All golfers want a putter that is capable of sweet impact, but none have that capability. It was high time that someone did something about that. Now after over fifteen years of Research and Development, only one golf putter has that critical capability, the QUANTUM GOLF PUTTER, and; it is ready for you to buy and enjoy the fruit of our comittment to the science of golf putting.
