Spin-Balanced Golf Balls
12/27/02: We all knew that balance-oriented golf balls flew and rolled better than their non-balanced
brethren. What we did not know was whether their performance improved enough to make all of the
inconvenience associated with them worthwhile. We guessed that they did not. We were wrong. Read our
Comparison Review.
Spin-Balanced Golf Balls - Do they really work better?
12/27/02: Weight is distributed in, through and around a golf ball as uniformly as individual manufacturing
techniques allow, but still, no golf ball is perfectly balanced when it leaves the factory. The Wilson True
balls come close, but even they are not perfect. "Spin balancing", as described in this article, attempts to
compensate for these irregularities in weight distribution. It is a process that does not actually change the
balance of a golf ball. Instead, it is a procedure that adds a line around the equator of a golf ball to
indicate that individual ball's optimal flight alignment.
This subject originally seemed to be a simple one, but this comparative review turned out to be a lengthy
one. Those readers with no pro-brevity biases may wish to begin with a page of Notes and Explanations.
This page concerns terminology, testing variables and info on other types of "balanced" golf balls. Those
who wish to cut to the quick may click here for The Summary of Conclusions. For a review of the
Technasonic Check-Go Sweet Spot Finder device used to spin balance the balls described in this
comparative review, please click here: Technasonic Check-Go Review
Now, on with the main review:
The Testing Procedure:
It can be assumed that properly aligned, balanced-oriented balls will fly and roll more consistently than
randomly aligned balls that are not balance-oriented. There is no point to arguing otherwise. What can be
debated, however, is whether unbalanced golf balls are so far out of balance that average players can
actually notice the performance differences in regular play. After all, balls can be aligned by hand only on
tee shots, before putts and when lift, clean and place rules are in effect. The rest of the time, in the
fairway or in the rough, balls have to be left as they are. When not aligned by hand, the markings on a
ball not only become irrelevant; they can actually serve as negative distractions for some players.
In order to find out if using spin-balanced balls does result in strokes shaved from the scorecard of the
average golfer, we used a very simple and very non-scientific approach. We took a mix of forty golf balls
of comparable hitting length - Pinnacle Gold Distance, Wilson Ultra, Top Flite XL and Maxfli Noodle - and
we divided them into two, evenly matched teams of twenty balls each. We then spin-balanced and
marked one batch using the Technasonic Check-Go ball-spinning device. We left the other batch as they
originally were - unspun and unmarked.
The two teams of balls were then hit head to head in four, different types of comparison sessions: 1.)
Putting from 13' on our True Board synthetic surface. 2.) Short/Mid Irons to a 150-yard pin 3.) Long Irons
(no specified distance) 4.) Drivers (no specified distance) In all ball-hitting sessions, the balls were
placed on tees. In total, 440 balls were hit. 64 balls were putted.
All input for this review is based upon sessions at the GCR range. There was simply no way for individual
playing rounds to be realistically factored into this review process. The benefit that results from using
balance-oriented golf balls comes from the accumulation of small, subtlety defined positives. Whether an
actual score would have been a stroke or two higher or lower had any round been played with identical,
but unbalanced, golf balls instead of balance-aligned balls would have been pure guesswork.
Putting Session Results
There simply is no doubt about it, balance-oriented balls roll better than randomly aligned balls. We did
not have to putt for long to realize this. On our dead-level, synthetic surface, the differences were readily
apparent to the eye. The balance-aligned balls rarely ever fell off left or right at the end of their roll. With
good strokes, they always tracked true through to the end of the last rotation. In bocce-ball putting
rounds, it was no contest. Putting was much more precise with the balanced balls.
In comparison, the non-aligned balls displayed typical rolling characteristics. Sometimes they stayed true;
other times they curled off at the end of their run. When poor balance alignment coincided with a weak
stroke, they could curl off, or "bleed", precipitously in their last few rotations. They could veer anywhere
up to ninety degrees. Even with a good stroke, they could plop over an inch or so left or right at the very
end. These tracking vagaries occurred to a very, very limited extent with balanced balls.
Our GCR testers, just like everyone else, tend to blame all deviant roll behavior on their putting strokes,
or on the putting surface’s break, even when no break exists. With the presence of balance-oriented balls
in an alternate-shot rotation, the putting characteristics inherent to the golf balls being used became very
apparent. This reduction in the tendency to curl off at the end of the roll produced dispersion patterns for
the balance-oriented balls that were two to three inches closer to the center of our grid on average than
those of the non-oriented balls.
These seemingly small differences will not make much difference to a lousy putter, but they certainly will
to a good one. The poor putter is just as apt to have his putts break towards the hole as they are to break
away from it. Not so with the player who generates a solid putting stroke and routinely keeps the ball
online. His putts will track truer and roll stronger. He will experience fewer lip-outs, curl offs, near misses
and putts that die right in front of the cup.
On heavily used greens, or ones that have their cups changed infrequently, slightly elevated “donuts”
occur around the cup. It will be here that balance-oriented balls impact putting efficiency most. Those
horribly annoying putts that seem to “change their mind” at the very last moment will occur less frequently.
A player with a poor stroke may never realize much benefit from the use of balanced balls on the green,
but a good putter should be able to reduce his handicap by close to a stroke with careful and sustained
use of balance-oriented balls. If he is also adept at using the alignment lines on the ball to aim his putts,
he may save substantially more than a stroke around.
Some of our testers had blasé attitudes about balance-orientation, but when the pressure putts came in
our bocce-ball putting contests, they all made dead certain that that alignment line was aimed precisely at
the tiny 5-point cup. The fact that comma-shaped putts rarely ever occurred with properly aligned, spinbalanced
balls had eluded none of them.
How did the spin-balanced balls compare to the saltwater-balanced balls we used in our True Rollers
putting comparison earlier this year? We saw even more improvement in roll characteristics using the
spin-balanced balls than we did with the saltwater balls. With the saltwater balls, we resorted to rolling
them off of a ramp to ascertain just how effective they were. With the spin-balanced balls we did not have
to. The differences were readily apparent. This is not a totally apt comparison, however. The spinbalanced
balls have straight alignment lines on them that assist in aiming. The saltwater balls had just a
dot on one side.
Irons Results - Long Iron Sessions
In our initial range sessions, we allowed testers to use any long iron they wished. Their assignment was
to hit balls straight out over a pattern of measuring stakes that were placed in the middle of the range. No
set end target or distance was specified. Their only assignment was to hit the ball straight. Problems
arose immediately. Most testers were too accustomed to working their irons into a specified target.
If a human tester routinely hits a fade or a draw, he is, of course, not aiming directly at the target. Should
he align the ball’s marker line at the pin, or on the line down which he intends to swing the club? Should
he align the ball with his stance, with his clubface or with his swing path? Everyone had a different
opinion. One of our faders actually aims and aligns a full fifteen to twenty feet to the left of the pin at 150
yards. One drawer of the ball hits from a closed stance with a pronounced in to out swing path. His
clubface aligns to the left of the pin.
To end the deliberation, we initially insisted that all testers align the ball’s marker line directly down the
center at all times. This caused considerable consternation for some testers as they tried to swing down
the line dictated by the ball’s marker line. Their muscle memory and ingrained swing mechanics fought
against them. Consequently, three different testers had the results of their first sessions discarded
completely. Their shot patterns were just too erratic. One could not adjust at all and did not continue to
test. The other two did make adjustments, or more accurately, they learned to ignore the marker line and
swing normally.
Asking our testers to become human Iron Byrons and to mindlessly swing long irons down the center of
the range turned out to be unproductive. Casual warm-up sessions worked well, but when the scoring
began, swings became generally stiff and awkward. Testers invariably tried to “stay down the line” too
long in an attempt to hit purely straight shots. Consequently, they became less accurate, not more.
(Having a scorekeeper standing behind them making “tsk-tsk” noises and commenting upon their swing
mechanics didn’t help, either.)
Another problem presented itself. If the alignment line on the ball is not precisely oriented, the entire
purpose of using balanced balls is nullified. Unfortunately, players cannot accurately align the marker line
toward the pin from address position. It must be done from behind the ball, and even then, the player
must step well back from the ball to check on his alignment. Impatient testers had trouble doing this every
time. We are sure that impatient players will not do a good job of this during playing rounds. As one tester
said, “I hate anything that slows the game down.” For him and one other, we placed the nub of red tee in
the ground eighteen inches in front of where they were hitting. They used the tee nub as a quick
reference point.
The upshot of these initial sessions was that the balanced balls registered marginally tighter left-to-right
dispersion patterns with the longer irons, but overall patterns were too erratic to be realistic. We
abandoned this approach.
Short & Mid-Iron Sessions
Next, we moved to a standard par-3 distance of 150 yards. This allowed testers to use a comfortable
short to mid-iron, and to maintain a consistent and easy swing. Also, our 150-yard target green is a
naturally shaped green of good size and is complete with traps and berms. It simulates on-course
conditions well. If balanced balls are to shave strokes off of a handicap, many of the strokes saved must
come from birdies that result from shorter first putts on par-3 holes. Par-4 and par-5 approach shots are
irrelevant since balls cannot generally be picked up and realigned in the fairway.
Fade Alignment
Draw Alignment
Our testers were much more comfortable with this par-3 approach. They now had a specific target. We
also allowed them to “cheat” on aligning the marker line on the ball. They could adjust it left or right a bit
to suit their swing needs. They soon found that aligning the ball directly at the pin was not the answer for
most. Swing path direction was generally the optimum choice – faders to the left and drawers to the right.
However, for those with exaggerated motions, a compromise line was best. For example: With a
pronounced out-to-in swing path and a very open club face, the most desirable alignment direction was
midway between the target line and the swing path line.
In six sessions, results were mixed, but the advantages of using balance-oriented balls began to become
apparent. Testers generally noticed that their most errant shots seem to come from the unbalanced balls.
After all shots were charted and tabulated, the balanced-oriented balls turned out to be four feet closer to
the pin on average than the randomly aligned, unbalanced balls. (Actually, it was 3’ 11 7/8”) In addition,
the patterns of the balance-oriented balls were marginally longer, as well.
Four feet may not seem like much at first glance, but over a full season, that distance will account for an
awful lot of birdie putts holed. A good putter sinks less than fifty percent of their putts from seven feet.
From three feet, they sink more than ninety percent of their putts. This gain in accuracy has to impact the
scores of better players. Higher handicapped players will see very little advantage, however. A chip from
forty-four feet is not measurably much more difficult than one from forty feet.
Driver Sessions
It was during the driver sessions that the balance-oriented balls began to shine in terms of both accuracy
and overall length gained. Using the average dispersion variable of 4' seen at 150 yards, we surmised
that using balance-oriented balls with drivers would produce patterns that were 51/2' to 7' closer to the
center of the fairway depending upon how far an individual drive carried. That estimate turned out to be
conservative. Precise measurements are not possible on our asymmetrically contoured range, but a leftright
dispersion improvement of 6' to 10' was our final estimate. The tightness of dispersion patterns
varied from driver to driver, tester to tester. There are a number of reasons for this: Different drives go
various distances. Different players impart different spin rates. Lateral spin rates increase with lowerlofted
driver heads. Poor balance orientation can exacerbate sidespin and increase inaccuracy to a
disproportionate extent for those who hit trajectories with pronounced curvatures – hooks, draws, fades
and slices.
Another factor widened the disparity of patterns of Balanced versus Unbalanced in our driver sessions.
Randomly aligned balls sometimes happen to set up in proper alignment position. When this occurs, they
perform just as the balance-oriented balls do. To eliminate this variable in the driver sessions, we spinbalanced
all of the balls on the Unbalanced Team and then made certain that every unbalanced ball was
teed up completely out of whack. Consequently, variations in the resulting driver patterns were
exaggerated beyond those that the average golfer would see in day-to-day play.
During the earlier iron sessions, the differences between the balanced and unbalanced balls were only
slightly apparent to the eyes of our testers. Some could see no differences at all during their sessions.
Until their shots were charted and tallied, they did not feel as though any substantial performance
differences existed. Such was not the case with drivers. It did not take long to see that the balanceoriented
balls were flying stronger and longer. The benefits were surprisingly obvious. The balls carried
better, flew straighter and rolled hotter after landing.
The balance-oriented balls not only created patterns that were six to ten feet closer to the center of the
fairway, they created longer patterns, as well. How much length was gained depended upon the length
and trajectories of the individuals hitting the drives. The balance-oriented balls easily produced the
longest drives in every session. The longest of all balance-oriented balls hit was more than seven yards
longer than the longest non-balance-oriented ball. The balanced-oriented balls accounted for sixty-five
percent of the longer half of the balls hit in the driver sessions and conversely, just thirty-five percent of
the shorter half.
In regular ball-testing sessions, we always eliminate weak shots from consideration – it’s not fair to a ball
manufacturer to include the results of bad swings. In this case, however, we eliminated only very, very
poor hits. We counted the weak hits to see if balancing improved the behavior of wayward balls. It did. In
each session, the shortest drives (the head-shake inducing clunkers) came from the unbalanced balls.
Some straight-hitters will see little or no actual yardage gains on average as unbalanced balls can turn
some straight drives into longer draws and some straight drives into shorter fades. That aside, it is
realistic to expect that the typical player will gain an average of at least two yards in distance by using
balance-oriented balls. Longer hitters will see as much as five yards in gain depending upon the nature of
their drives. How much straighter and farther will depend upon how much out of balance a ball had been,
and upon what type of trajectory and amount of spin was imparted to it. Balance-oriented balls create
more neutral and consistent results for those who work the ball in either direction. The sidespin that can
cause a pronounced fade to nose off and die at the end of its flight is substantially reduced. Power fades
land and run hotter. Draws are less apt to become hooks.
There turned out to be no physical way for us to measure how much balance orientation influenced the
amount of sidespin that occurred in slices and hooks. Visually, the differences were obvious, but there
was no way to ascertain the initial launch direction of the hooks and slices. Where the ball landed
depended greatly upon the tester’s initial stance alignment. Also, our test range is not balanced and
symmetrical, itself. Severe hooks are snagged by a berm covered in heavy rough. Distance deviations to
the far left can only be surmised. In spite of this, it can be safely stated that unbalanced balls do
exacerbate slices and hooks off of a driver and that mistakes are noticeably less damaging with balanceoriented
balls. While watching alternate-shot sessions, testers could actually see the differences in flight
between balance-oriented and intentionally misaligned golf balls. Into a head wind or quartering wind, the
difference became even more obvious.
Fade Alignment
Draw Alignment
One of our shorter fade-hitters was particularly appreciative of the improved flight characteristics of
balance-oriented balls. He would tag an unbalanced ball well and would be certain that it was destined to
end up out there with the best balance-oriented balls. It would appear to be flying strong and long, but at
the very end of its flight it would lose steam and curl off downwards to the right. It would land softer and
not run as the balance-oriented balls would do. He saw substantially better penetration to his high, soft
trajectories with the balanced balls.
Another tester, one who suffers from the occasionally disastrous hook, pointed out that excessive
sidespin from an unbalanced ball is just as apt to help correct a hook (or a slice for that matter) as it is to
exaggerate it. A balance-oriented ball will keep a ball from going more to the left by neutralizing sidespin.
Consequently, it can never make the hook go more to the right as the unbalanced ball might do. This is
true. However, if the standard hook costs a player about one half of a stroke on average, a hook made
more severe may result in the loss of two strokes since it is more apt to go into the water, the woods or
even out of bounds. A moderated hook is apt to benefit a player less than one made more severe will hurt
him. Those catastrophic hooks (and slices) not only cost multiple strokes, they demoralize, as well. One
can change the nature of an entire round.
As with irons and putters, accurate drivers will benefit most from using balance-oriented balls. The
landing zones on most fairways are anywhere from 100’ to 180’ wide. Left-right deviations in ball flight of
7’ or so will often be an irrelevancy for those players who are inaccurate to begin with. For players of all
skill levels, however, any number of fairway traps will inevitably be avoided over a full season and far
fewer drives will end up nestled just off the fairway in those pesky, first-cut grasses. How these benefits
impact a player’s handicap will depend upon the individual player.
A factor that almost all players cannot dismiss is the added distance advantage gained from driving with
balance-oriented balls. The extra yardage is not to be sniffed at. Best hits will be noticeably better with
balanced balls. This will occasionally mean that a player is hitting one less iron to the green – a 7-iron as
opposed to a 6-iron. As stated, our best test drive with the balance-oriented balls was seven yards longer
than our best with the unbalanced balls. And it should be pointed out that we did not use our longest hitter
in these sessions. We keep him away from our test balls. He sends too many OB left – way left – off the
range and into the neighboring tennis courts. We would extrapolate that he would see best-hit gains in the
vicinity of ten yards. We also extrapolate that he would see a reduction in damaged tennis players of
approximately eight percent. We mention this last factor only in passing. We certainly do not intend to
suggest that any serious golfer should ever factor the welfare of tennis players into his equipment
selection process. That, of course, would be heresy.
Summary of Conclusions:
Our GCR testers all entered this comparison review thinking that spin-balanced balls would play a bit
better than unbalanced balls, but that the difference would not be enough to justify the time and
aggravation that went with spin balancing. By the end of the review process it had become obvious to all
that balance-oriented golf balls performed decidedly better than their unbalanced counterparts, and that
these differences were great enough to make balance-oriented balls well worth the effort required in
playing them. Our crew became converts.
Spin Balancing manifests its advantages in three regards: 1.) Longer and straighter drives, 2.) More
accurate tee shots on par-three holes and 3.) Better-rolling and more accurate putts. Each of these three
individual factors could, in and of itself, knock a stroke off a player’s round. Conceivably, it is possible that
all three aspects could come into play during the same round. If that happened, multiple strokes could fall
from a score. A score of 80 might become a score of 78. A score of 71 might become a score of 68. It’s
not impossible.
In spite of its improved tendencies, a balance-oriented ball can still slice or hook. When pushed or a
pulled, it will still fly right or left. Balancing does not eliminate these mistakes. No internal homing device
becomes mysteriously imbued into a ball by the balancing act. It will fly straighter, but it’s still a golf ball
and will resort to bad behavior if not treated properly. What balancing does do is eliminate some degree
of counterproductive sidespin throughout a ball’s flight. As a result, most hits fly a bit stronger. They go
longer and straighter. The severity of mistakes is reduced.
There is a downside to using balance-oriented balls. Some players will not have the time and discipline
needed to mark all of their balls. Others will not have the patience required to align their balls precisely
before every tee shot and putt. Still others will find the marker lines they place on the ball to be ugly and
Lastly, ball balancing cannot tell a player how to align his ball. With experimentation, an individual can
learn exactly what alignment variation will work best for his game. If he then follows a routine and aligns
the ball precisely the same way every time, he will see performance that is much more consistent. There
is absolutely no doubt about that. In our opinion, the consistent use of balance-oriented balls can shave a
stroke or two off of the handicap of any player who possesses reasonably solid fundamentals.
Notes and Explanations:
It should be noted that throughout these articles the terms balanced balls and balance-oriented balls are
used interchangeably. Neither is really quite accurate. Spin-balancing does not “balance” a ball. Spinbalancing
only provides a visual indication of the axis upon which a golf ball will tend to spin best. The
distribution of mass in a golf ball is not changed the way that it is in a tire when balancing weights are
The term “balance-oriented” is more accurate, but it must be remembered that orienting a ball towards a
target does not make a ball fly in an oriented manner in and of itself. The swingpath of the club and the
angle of the face must both be properly oriented, as well. No magic occurs during the spin-balancing
process. All that the player gets from the procedure is an equatorial line on a golf ball. He’s got to do all of
the real orienting himself.
In reality, the term weight distribution axis-indicated balls would be more appropriate than either of the
above-mentioned terms. For obvious reasons, we have not used that clumsy phrase.
Technasonic uses the term, Sweet Spot Finder. This is misleading. The word "sweet" may be applicable
to how well an indicated ball might fly or roll, but the dot added to a golf ball by this process is not the spot
where impact is to be made. No "sweet spot" is defined in the sense generally used in reference to golf
club faces, tennis racquets and baseball bats.
Degrees of Imbalance
The Technasonic Check-Go device (see review) used in this review cannot realistically indicate how
much a ball might be out of balance. Some balls will benefit greatly from “balancing”. Others will see
virtually no benefit. Degrees of imbalance will vary from one brand of ball to another. No company
intentionally manufactures unbalanced balls, but some degree of imbalance is inevitable. Even balls from
the same line will vary from ball to ball.
For anything close to legitimately balanced golf balls, the only options are the Wilson True balls. While
Wilson’s competitors enthusiastically point out that the Trues certainly are not technically perfect either,
they remain the only balls that can claim to be truly “Balanced”.
Wilson True Balance
We included the Wilson True Distance balls in a number of comparative sessions to get an indication of
how truly balanced balls performed in comparison to balance-aligned balls. The Trues behaved in a very
neutral and accurate manner. They produced consistently good patterns. They did not, however,
generate the strong, penetrating types of trajectories we saw in the spin-balanced balls. The explanation
for this is simple: Spin balancing reveals the line upon which the heaviest segments of a golf ball will align
while spinning. This creates a straighter and more powerful flight. The Wilson True balls feature very
evenly distributed weight patterns. Hence, they fly in a much more neutral manner. We actually preferred
the flight characteristics of the spin-balanced balls.
Note: The use of spin-balanced balls with balance orientation lines drawn on them does not violate
USGA rules. It is perfectly acceptable in all instances. To intentionally manufacture a lopsided ball that
flew best upon an indicated line would be violation of USGA rules.
Saltwater Balancing vs. Spin Balancing
It should be pointed out that spin balancing and saltwater balancing are different procedures that yield
different indications. Balls tested using each procedure end up with two different top spots – and the
differences are not always constant from ball to ball. As one astute reader quickly pointed out after our
True Rollers putting review last spring, saltwater balancing yields a lightest segment up result. It does not
reveal the axis upon which a ball will best spin or roll. It cannot be assumed that a ball’s lightest segment
is the polar opposite of its heaviest segment. Weight and mass can be dispersed in any number of oddly
distributed patterns. For putting purposes, saltwater testing may be a preferred technique, but for hitting
(flying) purposes, spin balancing is the obvious choice.
Saltwater-balanced balls leave a player with a visible dot on the lightest side of the ball. Spin-balanced
balls leave a player with a visible line on the equator of the ball. Some players are going to appreciate
this; others are not. If the use of that line suits a player’s style and mechanics, and if a player is welldisciplined
and takes sufficient time to accurately align the marker line on his ball every time it is
permissible to do so, then immediate benefits will befall him.
We did not test saltwater-balanced balls in any regard other than putting. The opinions of most outside
sources validate what common sense dictates: Spin-balanced balls will outperform saltwater-balanced
balls when it comes to flying through the air.
Testing Procedures
Some of our more analytically minded readers may be tempted to point out to us that a more accurate
testing procedure would have included the placement of phony alignment lines on the unbalanced balls.
This would have eliminated the visual input variable caused by the alignment lines on balanced balls. We
considered doing just that, but decided that the primary concern of the test was whether a player
benefited from playing balanced balls, and such balls do, by necessity, have marker lines on them.
Unbalanced balls used in play will generally have no marker lines on them. These black alignment lines
can exert either a positive or a negative influence on a player depending upon how he is disposed. The
use of a clean, unmarked ball is a primary factor in deciding which kind of ball to play. A couple of our
GCR regulars have real aversions to any logos or markings on a golf ball. The marker lines on the
balanced balls looked as ugly as sin to them.
Some of our more analytically minded readers may also want to point out that this testing procedure may
have been handled better by an Iron Byron. They may be right on this point. It certainly would have been
less frustrating and time consuming. But again, the test was to see if human beings benefited from using
spin-balanced balls. An Iron Byron would have been oblivious to the visual impact that the alignment lines
had on a human golfer’s game. The nuts and bolts of the primary dilemmas that haunted some of our
testers would have eluded Mr. Byron’s mechanical psyche completely.
Technasonic Check-Go Sweet Spot Finder
12/27/02:Technasonic Electronics is located just north of Chicago in Lincolnwood, Illinois. The company
has been producing the Check-Go Sweet Spot Finder since the late 1980’s. Unfortunately, not that many
players knew about it until the release of the Wilson True golf balls. All of the attention (and debate) that
Wilson brought to the performance characteristics of balanced balls also brought the Check-Go into the
The Technasonic Check-Go is a compact, little device that spins golf
balls at very high RPM’s. After a period of fifteen to twenty seconds, the
ball settles into a constant position as it spins within the Check-Go’s
cradle. At this time, the user takes a small marking pen (included with the
Check-Go) and makes a dot on the top of the ball. He then inserts the
pen into a side porthole and creates a thin line around the equator of the
ball. This equator indicates the weight-distribution axis that will allow the
ball to carry longest, strongest and straightest.
Though the company calls the Check-Go a “Sweet Spot Finder”, the
device does not actually locate any one sweet spot on a ball’s surface.
Instead, it locates a preferred alignment direction upon which the ball will
best fly. The “spot” that is marked on a ball faces the player at address
position. Impact is supposed to be made at the equatorial marker line.
This line points down the desired path of the ball’s upcoming flight. The
equator may be rotated to any position along its 360-degree path.
We did not have much doubt at GCR that spin-balanced balls were
effective to some degree or another. Common sense dictates that they
would be. What we did doubt was whether a simple, little mechanical
gadget such as this one could possibly do a reliable job of spin-balancing
golf balls. It turns out that the Check-Go is, while not perfect, more than up to the task at hand. For an
inexpensive device, it manages to do a very fine job. When the spinning process is applied repeatedly to
the same ball, an identical equator is always found. At least the equator is identical in relationship to the
casing of the device. Human hands can tilt the marking pen at slightly different angles to create equatorial
marks that trace a bit off center. An off-center line can be visually annoying, but it does not actually affect
performance in any way. The ball still sets up in the appropriate position.
Aside from the leeway allowed by the pen, other problems can occur. Too much pressure applied to the
pen point as it presses against the spinning dimples can damage the pen. This happened with our test
unit and the pen soon became a little gooey and messy. We recommend that users of the Check-Go
exercise a very light touch when making their lines. They can darken the line after they have removed the
ball from the device.
Another small problem arose in that the small cup that holds the ball got a touch out of register. It still
made the ball spin just fine, but the top mark on the ball (which becomes the side indicator at address)
registered a few degrees off kilter. Again, this did not really affect performance.
Aside from these minor problems, the Technasonic has managed to spin an awful lot of balls for us, and
there seems to be no indication that it will not continue to do so for a long time to come. The main
drawback to the Check-Go, now and forever, is the planning and discipline required to make certain that
all of a player’s golf balls are properly marked. It takes less than five minutes to spin and mark a sleeve of
golf balls. The trouble is, the spinning and marking can’t be done properly in a haphazard manner. Solid
concentration has to be maintained. Many players grab a sleeve or two of golf balls at the pro shop before
rushing off to the first tee. Many also cannot resist the temptation of playing golf balls that they glean
during the round. In either case, the odds are slim that they are going to find a nicely level bench where
they can conscientiously spin-balance their golf balls, even if they have remembered to pack the Check-
Go in their bag in the first place.
The Check-Go will always be most productive for those who buy their favorite balls by the dozen, mark
them carefully at home, and then make certain that every ball in their bag is a spin-balanced ball. Let’s
face it; the average golfer has trouble remembering to check their bags for tees and ball markers. They
aren’t going to be able to sustain the level of conscientiousness required by the Check-Go. That’s shame,
because this little gadget really does work well. It can save anyone a bundle of strokes over a season.
Thoroughly cleaning the grooves on all irons and wedges works wonders, as well, but a depressingly low
number of players manage to do it regularly. Even fewer carry one of those handy, little carbide-tipped
groove cleaners in their bag. Most just use a blunt, wooden tee for the job.
Balance-oriented balls perform noticeably better than randomly aligned balls. We at GCR now swear by
them. (See our Featured Comparison Review) The Technasonic Check-Go is really the only option
available for spin-balanced balls. It works very well. It. Every golfer above the level of Hacker will benefit
from spin-balancing their golf balls. If you are lazy and disorganized, forget it. If you have a modicum of
self-discipline, get a Check-Go right away, and take the time to make certain that all of the balls you play
are balance-oriented. A score of 80 shot with randomly aligned balls will almost certainly become a score
of 79 or 78 with balance-oriented balls.
Note: Technasonic’s Check-Go is available to distributors in an unlabeled, unadorned state.
Consequently, it may be found with other brand names affixed to it, or it may have no brand name at all.
As far as we know, all of the little spin-balancing machines out there are the same item described above.

Perfectly Balanced Ball

What You Should Know - What You Can Do

By Leonard Finkel

biggest controversy in golf today is the "perfectly balanced"
golf ball. Wilson, with its " Staff True" ball, makes just
that claim, its box bearing the words, "Perfectly Balanced".
Golf manufacturing hasn't the precision of rocket science and tolerances
involved (allowable margin of error), are looser. For instance, Tour
players may request as many as twenty drivers with the exact same
specifications, only keeping the few that perform best for them. Even
though they were made exactly the same, none are exactly the same. Is it
realistically possible to consistently make a perfectly balanced golf
ball? I didn't think so and decided to do a little research.

I made
two important discoveries. First, there is no such thing as a
consistently perfect balanced ball. Wilson vice president Luke Reese
admitted he would be foolish to make that claim. "I'm not by any
stretch saying that every single ball is 100 percent perfectly balanced.
The problem with golf balls is, with any product, you have manufacturing
variances and that means you can't make all products exactly the same
each time. There is no such thing as perfection." He did maintain
that perfection to Wilson was that the ball is going to "putt where
you put it." The second thing I learned is that there is something
you can do to better balance the golf balls you play with, no matter the
brand or model. A little known device called the Check-Go is the answer.

Optimum Balance

I came across the Check-Go sometime ago, but didn't give it much
consideration. Though it has been around for almost fifteen years,
Check-Go has not drawn much attention. The "Ball Wars" brought
it into focus. An amazing tool, it spins a golf ball at approximately
10,000 revolutions per minute. As the ball rotates, it spins all
directions to find its optimal balance point. After twenty seconds or
so, weight deviations cause the ball to settle into a position it will
return to time and again. While the ball rotates, a line is drawn to
indicate its balance point, a marker positioned to precisely denote the
ball's equator (optimal point of balance). A perfectly balanced ball
will not come to rest at the same point consistently. Every test would
result with a new equator being marked and these lines would eventually
cover the ball. I tested more then 100 balls, from every major
manufacturer, and each ball returned to its initial equator, every
single time!

Experts agree that golf balls today are far superior and better balanced
then balls from ten or twenty years ago. As good as they are today,
allowable tolerances make it impossible to consistently manufacture a
perfectly balanced ball. The bad news is, while most of the balls are
well balanced, you don't know which ones they are. The good news is,
using the Check-Go, you can determine for yourself the best point of
balance for every ball you put into play.


Golf balls were spun for at least 20 seconds for the Check-Go to
determine its optimal balance point; enough time to ensure balancing was
complete. As the ball continued to spin, a line is drawn along the
equator. No matter the brand, no two balls had the same balance point.
The balance points were so diverse, as if totally random; meaning where
the logo is placed had nothing to do with the balance point of the ball.
The common custom of lining up the logo towards the target is therefore
irrelevant. Each ball was tested multiple times, confirming that balance
points remained in the exact same place, on each test, for every ball.
During retesting, it was easy to recognize when the balancing process
was completed. Balls were balls randomly positioned before retesting and
as they rotated, the previous equator line almost magically appears, the
Check-Go once again finding the identical point of balance. This study
was not scientific in nature and I draw no conclusions as to which golf
balls are better. I only sought to determine if there is such a thing as
a golf ball that is consistently, perfectly balanced.

Pelz Speaks

I spoke with putting guru Dave Pelz, who states there are numerous
reasons why putts are missed, one of which is an unbalanced ball. When
he first began his research, Pelz, a former NASA scientist, found most
balls to be poorly balanced. When he asked major manufacturers why they
had not strived to achieve a balanced ball, he was told that
aerodynamics, not balance, governs distance. Distance is what almost
every golfer is seeking, so that is where research dollars went. Today
Pelz adds that most of the major brand balls are much better balanced
than their predecessors, but consistent perfection is still not a

Pelz pointed out that an unbalanced ball could certainly be the
determining factor in a missed putt for Touring pros or better putters,
those that hit the ball where they aim. A few days after our
conversation I was watching the final round of the PGA Memorial
Tournament. Jim Furyk and Vijay Singh were coming down the stretch, both
with similar putts. Vijay outside, Furyk had to mark his ball. Singh's
putt rolled dead straight, missing the hole. Furyk putted on the same
line yet his ball broke left, also missing the hole. I remember
wondering at the time if one or both balls not being optimally balanced
caused either of those misses. Using the Check-Go will not give you a
perfectly balanced ball. What it will do is let you know where the
equator, the optimal balance point of that specific ball you are using
is. Pelz says he doesn't know how balance affects the flight of the
ball. What he does know is it most definitely affects the ball as it
rolls on the green. Not finding the balance point surely puts any golfer
at a distinct disadvantage!

Gunn…Lehman & Pate

Teaching pro extraordinaire Roger Gunn introduced me to the Check-Go.
Roger, who has worked with among others, PGA Tour pros Tom Lehman and
Steve Pate says, "I don't get excited about too many things at the
PGA Show, but the Check-Go was definitely the product of the year. It's
simply the world's greatest golf gizmo. I had to have one myself within
30 seconds of seeing it work. I spin every ball I use prior to putting
it in play." Gunn asserts that it is difficult to quantify the
results from using the Check-Go, but if even if it is only one shot per
round, the accumulated strokes saved is enormous. Virtually every one of
his students uses it. "Ask Stuart Cink at the U.S. Open last year
if he thinks one stroke on the green makes a difference?" Gunn

Gunn showed the unit to Ryder Cup veterans Tom Lehman and Steve Pate,
who were impressed with it and each requested one. Roger related a
Lehman story. Tom, who currently plays the Srixon ball, likes to line up
the ball logo to the target when putting. "Srixon is a
well-balanced ball, but you never know quite where the true equator is
going to be," Gunn adds. Tom got in the habit of spinning every
ball he used and he would only use the ones where the equator lined up
with the logo. According to Check-Go president Kenneth Burnett, he
received an urgent call from Gunn. Roger said Lehman needed a Check-Go
immediately. Burnett was told to overnight a Check-Go to Lehman in time
for the 2002 AT&T Pebble Beach PGA event.

not scientific, Gunn has conducted his own tests rolling balls across a
hard, flat surface on the equator and also by placing them in a
"lopsided" position. He definitely notices a difference.
"It's similar to putting mud on the side of a ball. On a 10-footer,
it can miss by two and a half feet. A lopsided ball can miss a
ten-footer on a perfect surface. How many of us have seen a ball roll
perfectly, dead center as it nears the hole, then bleed away at the last
second? How many of those were the golf ball after all?"

Balance" Dissenters

Wilson's Reese talks about testing performance under "lab
conditions" yet Callaway's Larry Dorman and others speak of
performance in "real golf situations." They say that golf is
not played in a laboratory. Dorman adds that Callaway is very careful
to, "Avoid the use of the word perfect, because perfect implies
exactly what it says. And there is no such thing in a manufactured
consumer product." Srixon's Mike Pai adds, " You see the tests
that they (Wilson) run in their commercials and at the PGA Show on
something that basically resembles a pool table. I don't know any golfer
that putts on a pool table. I think what they've created has come from
things that happened a long time ago with golf balls, all the stories
about Ben Hogan applying Epsom salt and picking out one or two balls out
of a dozen. That was because manufacturing tolerances back in the 40's
and 50's aren't anything close to what they are today." While all
the other companies seem to focus on aerodynamics (distance), Wilson is
hanging its hat on balance. Golfers will cast their votes with their

Snell of TaylorMade Golf states, "As far as the tolerances go in
golf equipment, and it's not just golf balls, it's pretty much all the
golf equipment, one of the things you'll find is there's always
something wrong, an imperfection. If it's a shaft, if it's a club head,
if it's a golf ball, there are a lot of different variables that affect
overall distance, overall spin rates, compressions, and velocities. My
opinion is that there are a ton of imperfections in golf balls, to have
something that is perfect…it is nowhere near perfect. When you make
core batches, the core batches have a specific gravity formulation and
there's no way that every formulation comes out the same. The
compression ranges, when you measure balls that are finished are huge.
Within a dozen, you can take golf balls and do core compressions or
finished ball compressions and you can be ten to twenty compression
units apart, in one dozen that are supposed to be made the same."
Snell also confirmed what Pelz said about manufacturers seeking
distance, in some cases, actually shifting weight to increase distance.
He asserts from testing done at TaylorMade, that "perfect
balance" is insignificant in adding distance.

one of the co-inventors of the Titleist Professional ball adds,
"Everybody's launch conditions are not the same and one ball for
one person may not be optimum for someone else. That's the benefit to
the custom fit line that's going on now. The position that I take on
distance is that you should go out and find the ball that you like from
the fairway in, find that ball that you're comfortable with the spin,
the feel, the overall performance, then go get custom fit for a driver,
which will optimize launch conditions. I would add, once you've found a
ball you are comfortable with, that performs the way you want getting to
the green, use the Check-Go to find it's optimum balance. You will have
the best of both worlds…a ball that performs to your swing
specifications and the truest roll possible on the greens. Golf balls
are available everywhere. Information on the Check-Go is available at

"The World's Greatest Golf Gizmo"

began as an investigation into the ball balanced ball claims and counter
claims, led me to eye-opening discovery. While manufacturers disagree
over whether a balanced ball increases accuracy and adds distance to the
ball in the air, there is no question balance affects putting. I found
the Check-Go by Technasonic to be invaluable in determining the optimal
balance point (equator) of every ball tested, including the Wilson True.

Check-Go has been on the periphery of golf for almost fifteen years. It
was even featured in the New York Times in October 1988. The current
balanced ball issue has brought it to the forefront. According to
Check-Go inventor Ken Burnett, on the second day of the PGA show, he
overheard a Wilson rep at his booth comment," Boy, I didn't realize
we launched a multi-million dollar campaign to sell the Check-Go."

spinning a golf ball at 10,000 revolutions per minute, the Check-Go
automatically realigns the golf ball's heaviest areas along its equator,
so that a less than perfectly balanced ball no longer has a tendency to
wobble, but rather roll more accurately on the green. The Check-Go will
not make an unbalanced ball perfectly balanced. What it will do is show
you the optimal balance point of each and every ball you put in play.

testing for a balanced ball article, balls from every major manufacturer
were tested, including the Wilson True. At least two sleeves of each
type were tested (a dozen Wilson True balls) and in every case, the
Check-Go found the balance point of each separate golf ball. Each ball
was tested multiple times to confirm that the initial point of balance
was indeed accurate. Had there been any perfectly balanced balls, each
separate test would have produced a different equator, which never
happened. Every ball returned to the same balance point time and time
and time again.

world's foremost expert on putting, Dave Pelz attests to the fact that
balance definitely affects the ball as it rolls on the green. In The
Wire, an Internet news service, a promo for the July issue of Golf
Magazine talks about an article titled, Does Balance Matter? It writes,
"There's been a lot of talk lately about golf balls and balance,
but Dave Pelz has been saying for nearly 20 years that many balls are
out of balance, sometimes enough to affect the roll and result of your
putt. In research conducted at the Pelz Golf Institute, he calculated
that when a ball's center of gravity is off by just a few thousandths of
an inch, it can cause a short putt to miss the hole."

pro extraordinaire Roger Gunn, who has numbered among his students PGA
Tour pros Tom Lehman and Steve Pate, says. "I don't get excited
about too many things at the PGA Show, but the Check-Go was definitely
the product of the year. It is simply the world's greatest golf gizmo. I
had to have one myself within 30 seconds of seeing it work. I spin every
ball I use prior to putting it in play." In a game where every
stroke matters, can any of us afford to give strokes away?

the Check-Go can't make an unbalanced ball perfect, it will show you its
optimal balance point. I now mark the equator on every ball I put into
play. To not take advantage of this state of the art technology would
almost be a sin.


The Science of the Golf Ball
Spinner Sweet Spot Finder

Upon impact, the ball shoots forward with a velocity of about 50-100
mph. At the same time the loft angle of the clubhead causes the ball to
spin at about 2,000-10,000 rpm.

The effect of the back spin imparted generates two newtons of lifting
power (5 times the power of gravity). This is called the Bernoulli
principal. It is the lifting power which determines the flying distance
of the ball. The balck spin also improves stopping on the green with
iron shots.
