"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. |

"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.

"I have no doubt the golf balls roll
much smoother than they did with any of my former putters (Ping, Ping G5i

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. 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."

GOLF PUTTERS GOLF PUTTING VISITORS

Our mission was to develop a putter which eliminated anything that would cause
you to miss putts and included everything that would help you make putts.
Nothing more, nothing less.
What a physicists would call
"Elegant", and what a golfer might call "Sweet", and what we
call "Precision Performance Putters".
Product Requirement
Basically, golf
putters have only three components: 1) Grip, 2) Shaft, 3) Head.
 Grip
-- The best putter product would require durable non-absorbent symmetric tactile
grip; such a grip was found currently on the market so our product will embody
that already developed grip. However, if a client prefers another grip then we
can upon special order, ship a Quantum Putter without a grip so when it arrives the
client can have installed the grip of his personal choice.
 Shaft
-- The best putter product would require a durable straight shaft which is
available in lengths ranging from the USGA minimum of 18 inches up to an upper
practical limit of say 54 inches or so (the USGA is silent on an upper limit
shaft length); such a shaft was found currently on the market available in three
lengths within our desired range, so our product will embody that already
developed shaft and our factory will cut the shaft to our client's exact fitting
specification.
However, if a
client prefers another shaft then we can upon special order, ship a Quantum Putter
without a shaft so when it arrives the client can have installed the shaft and
grip of his personal choice.
Head
-- The best putter product would require all of the technology advancements that
our research and development has discovered. Currently there is nothing on the
market that in any way resembles the head of our prototype putter or any that
even comes close to satisfying our new technology putter head requirement, so we
must engineer and produce our own head. The parts that comprise our head are: 1)
Body, 2) Hosel, 3) Glide Plate, 4) Practice Knob and Alignment Pegs, and 5)
Power Adjustment Weights.
-
 Body
– The best putter product would have a range of
body masses, so that clients could choose the head mass that was most suitable
for their physique and conditioning. Accordingly, we offer three bodies: 1) A
lightweight but still massive Model X, 2) a medium weight XX, and a
heavyweight XXX. All will be made of solid brass because of its high atomic
weight and its classic authenticity and all will be given a matte finish by
bead blasting so as to minimize annoying reflection and the noticeability of
normal wear and tear. No coating will be used so the head bodies will be
authentic and allowed to age to an antique patina over time. A bull’s eye will
be precisely machined into the striking face of the head to show the exact
sweet spot of the putter head (it will also be our way of showing respect for
Reuther's old putter upon which we based our new technology development), and
this bull’s eye will be filled with black epoxy paint. The company/product
identity will also be machined into the striking face and also filled with
black epoxy paint.
-
 Hosel
– The best putter product would have a range of shaft angles so that clients
could specify a perfect fit for their unique putting style, putting stance and
physical stature. Accordingly, we offer seven hosels with shaft angles ranging
from the USGA Maximum of 80 degrees down to a practical minimum of 68 degrees
(the USGA is silent of minimum shaft angle) as follows: 80, 78, 76, 74, 72,
70, 68 degrees. Hosels will be made of aircraft quality aluminum and anodized
black. Alignment lines and dots will be precisely machined into hosels and
then filled with bright white epoxy paint. Because our hosels will be
rotatable for play/practice convertibility and left/right adaptability, and
power adjustability, they will be secured to the head body with a special
stainless steel screw that, in conformance with USGA regulations, requires a
special key to unsecure.
-
 Glide Plate – The best putter product would have a glide
plate that elevates the leading and trailing edges up off the green to prevent
bite and drag, and is grooved so as to self align the head perpendicular with
the intended ball launch line, and is a replaceable part so it could be
renewed as it eventually wears down after hundreds of round on golf.
Accordingly, we embody such a glide plate into our production putter and it
will be made of durable black composite material and secured into the head
body with special stainless steel screws which use the same special key that
is used to
unsecure the hosel.
-
 Practice Knob and Alignment Pegs – The best putter product would convert to a practice mode that
unobtrusively embodied all the practice aids necessary for the improvement of
putting technique. Accordingly, we embody a convex practice knob which
is permanently attached to the back side of the head body at precisely the
location of the head’s sweet spot so that when the putter is converted into
its practice mode, the purpose of this Practice Knob is to train the golfer in
hitting such sweet spot. We also embody holes machined into the putter head
which will receive lightweight alignment pegs, the purpose of which is to aid
in the proper X-Y-Z alignment of the putter during practice.
-
 Power Adjustment – The best putter product would be power
adjustable for the conditions of the day. Accordingly, we embody such
adjustability as follows: When the hosel of our putter is unsecured and
rotated open it exposes two canisters for the purpose of power adjustment.
When these canisters are left empty the putter is in its least powerful
configuration (useful when greens are fast or golfer's mood is aggressive);
when these canisters are filled with the two heavy brass weights that are
provided, then the putter is in its most powerful configuration (useful when
the greens are slow or the golfer's mood is timid); and when these canisters
are filled with the two lighter aluminum weights that are provided, then the
putter is in its normal power configuration.
We engaged an
ISO9001/AS9100 Certified Tool & Die Company in Glendale AZ USA to make our head
parts and we established a factory in Phoenix AZ USA to assemble parts into
putters and then, after rigorous quality assurance testing, ship they ship finished
product directly to our clients.
Product Specification
Quantum Putters
are made in accordance with Duane Engdahl’s Research and Development and his
latest design and utility patents. It has perfected grips, perfected
shafts/shafting, and perfected heads; plus they are convertible from the USGA
Conforming Play mode to a practice mode which enables the user to perfect all
aspects of his putting technique; plus they are power adjustable for variable
conditions of the day; and they are adaptable to either left or right handed
players.
No other putter
on the market comes close to the product specification of the Quantum Putter,
hence the Quantum Putter is unique on the market today; and since many of the
perfections embodied in this unique putter are patent protected until the year
2026, no other putters can be developed which rival the Quantum Putter for a
long time to come.
Quantum Putters are available in three models:
-
Model X which is the light-weight at 12 ounces and it
measures 1.25 inches from top-bottom, 4.0 inches from toe-heel, and 1.0 inches
from front-back. This model is most suitable for golfers who have very good
physique and a well developed putting stroke.
-
Model XX which is the middle-weight at 16 ounces and
it measures 1.25 inches from top-bottom, 4.0 inches from toe-heel, and 1.25
inches from front-back. This model is most suitable for most golfers.
-
Model XXX which is the heavy-weight 20 ounces and it
measures 1.25 inches from top-bottom, 4.0 inches from toe-heel, and 1.5 inches
from front-back. This model is most suitable for golfers who want the benefit
of stroke stabilization.
Quantum Putters are available in seven shaft angles:
Quantum Putters are available in thirty-six shaft lengths:
-
The
USGA
minimum 18 inches ranging up to 54 inches in 1 inch increments, so a perfectly
fitted shaft length is possible (again, contact us
for fitting instructions or click here for
do-it-yourself fitting).
Price and Value
A Quantum
Putter is priced at $495 no matter which head weight or shaft angle or shaft
length you specify (be advised that the price of Quantum Putters in
countries outside of the USA varies depending upon importation duty). In all
likelihood, the price of the Quantum Putter is higher than any other putter you
have ever considered purchasing, but we ask you to consider product value and
performance
instead of product price in your purchasing decision.
Every student of Logic 101 has been asked
something like this at one time or another:
"If three door-to-door vacuum
cleaner salesmen come to your house and each says his vacuum is the best, how
can do find out which is really the best."
The answer of course is to ask each salesman which
is second best. By doing this, you remove the bias each salesman has for his own
product and get to the truth - the best vacuum will always get two out of three
votes. If you ask us which putter is the best, obviously we will say it is the
Quantum Putter because we believe with all our heart and mind that facts and
physics back up our conclusion. But, if you were to ask a celebrity professional
golfer which putter is the best they would by their sponsorship contract have to
tell you it is the putter they are currently using, whether it is really the
best or not. So if you are looking for guidance from others as to which putter
is the best you will have to resort to the...
"GET TO THE TRUTH PLOY".

best? Click here for answer.
