Putter Fitting: Why everyone can benefit from Quintic



This is the first installment of a four-part series from Modern Golf on putter fitting and Quintic System. 

When it comes to putting, everyone thinks they’re an expert.

At least once, we have all been told what we were doing wrong on the putting green and how we SHOULD fix it. We see this universally — most golfers want to help other golfers get better. But are they really helping, and is the information they’re sharing accurate?

The truth is, without quantifying the given information, the answer is usually no. A system we use at Modern Golf called Quintic Ball Roll provides these answers by accurately measuring the interaction between the clubhead and ball. By doing so, a golfer can identify why they have certain habits. More importantly, they’ll know how to make the proper changes. Tangible results are the key to helping golfers with their putting technique and thus, the study of ball dynamics is here to stay.

The Quintic Ball Roll portable unit consists of software and a high-speed camera that can be connected to any computer. Quintic captures 14 different data points at up to 360 frames per second from the beginning of the stroke to the first 16 inches of the putt. What makes Quintic most useful is that it gives ball data as well as clubhead data graphically and numerically. This allows the golfers and fitters to identify how the head of the putter moves through impact and how this affects the roll of the ball. Making changes to the stroke and the putter becomes easier as information is quantified.

Golfers of all skill levels can benefit from using Quintic. For a novice golfer, identifying something very basic in their putting stroke can have a measurable impact on lowering their scores. Something as simple as controlling launch angle can take strokes off ones game.

Some of the best players in the world are also using Quintic on a daily basis. Quintic has helped Rory McIlroy, the world’s No. 1-ranked golfer, as well as FedEx Cup Champion Henrik Stenson and Open Championship winner Darren Clarke, to name a few. For these players, making or missing a putt can be the difference between winning and losing, and hundreds of thousands of dollars in prize money.

At Modern Golf, Quintic plays an integral role in our fitting experience. It eliminates any guess work involved in selecting a putter or fitting a player’s current putter. Through the collection of Quintic data, a professional fitter can then accurately and scientifically start to adjust an existing putter OR fit golfers into a putter that’s more suitable for their stroke.

Golfers can also instantly see why they may have certain tendencies. For example, if they have an inclination to miss putts on the left side from inside 10 feet, they may have a face angle issue. To make putts from inside 8 feet, we’ve learned that the face angle needs to be less than a 1 degree open or closed to the target. By identifying the face angle error we can help golfers eliminate that miss. In addition, all the data is saved for future reference to measure improvement.

Statistically, the greater mass of golfers are not getting any better at golf. How can this be with all the advances in knowledge and technology? We think it’s the inability of golfers to see tangible results. Taking a final exam and not wanting to know your grade wouldn’t make much sense if your goal was to get smarter. Players can see results faster if they can identify their flaws and then work to remedy those flaws. Turning three putts into two, two putts into one — that is how to lower your scores. Quintic gives golfers this real and reliable data. That why if you are not using Quintic, you are instantly at a disadvantage.

Sadly, most golfers who haven’t used Quintic are, more than likely, practicing the wrong technique. A golfer’s perception of what they think they are doing versus what they are actually doing is often skewed. So the solution is simple — no more guess work. No more relying on what Mr. Smith told you on the putting green just before you teed off on day one of your Club Championship. Whether you are a scratch golfer or 30-handicap, we guarantee results using Quintic Ball Roll.

During a one-hour putter fitting (it costs $100), our professional fitters will accurately adjust a golfer’s existing putter or fit them into a putter that is more suitable for their stroke and ball roll. Players will leave with a fully fit putter and data for their future reference.

    Little known fact: A putt that skips goes very straight. Air has less resistance than the ground. Speed is determined by force and loft at impact.

    “True roll” is a BS marketing term used to sell stuff.

    How does this device differ from SAM Putting Lab? Anyone know?

    • Brian

      Jan 30, 2015 at 6:23 am

      Quintic is different from SAM because nothing attaches to your putter. It reads the putter as well as the ball roll. While it is important to have a proper putter it is still more important to be able to roll the ball on the intended line consistently with a consistent roll. This system shows lots of data that relates to both.

      SAM reads the direct 3D movement of the putter with highly accurate technology. So all aspects of the full movement can be analyzed.
      For the ball roll the SAM only does a estimate on how the putter face comes to the ball. There is a spin and direction prediction which is based on the physics of contact of putter face and ball.

      The Quintic also can measure parts of the putter movement with the extended software package. Difference to SAM is that the analysis is based on a sticker on the putter head and image analysis algorithms. This will allow quite good readings for position and maybe loft. But for face angles or path or lie the accuracy will be not as good as SAM. Also the putter can only be analysed in the view of the camera – which is limited to a short range around impact.

      The ball roll is very important for a good putt. However, the putter movement is what controls the ball roll in the end. If you want to improve this you need the full picture of the putter movement to know what to change. Optimized putting stroke will automatically lead to better ball roll.

        ^ this is exactly it. A camera based system from the side doesn’t capture the whole picture. When the ball is not directly in front of the lens then what? I’ll take a Puttlab any day over this infomercial.

    Great article and every article ever written is basically an advertisement for everyone no matter what it is. Especially in the golf industry to be successful you have to advertise your self 100%. And the comment about the glass door. Lol.

    Great article and play well

    There is nothing quite like the acid test of placing a club in your bag, which is why I have decided to go the old-fashion way of putter fitting and purchase a bunch of cheap old classics of high quality and various styles to see what type fits me the best. I’m also doing the same for my irons and shafts.

    I find in the store or in a booth feels different from the course and driving range, and as such the results are not accurate.

    We appreciate the early feedback. However it is important for us to mention that this article is not designed to promote our facility, it is the first of a 4 part series on how our technologies can help the average golfer. This article is just the introduction to how we at Modern Golf use Quintic Ball Roll technology.

    We appreciate you taking the time to read the article and we look forward to hearing your feedback on the remainder of this series.

    As a frequent reader of this site, I really hate clicking on an article only for it to be an advertisement

  7. Jason Lloyd

    I’m confused…

    Is this an advertisement? If it is, it’s not a good one. I’d at least get the door leaning against the wall out of the picture and maybe have a club-fitter in the picture???

    Is it an article? If it is, it’s very poorly written and wrx needs to step it up.

    Quintic is very cool tech, but it’s obviously not solving this guys problem of his eyes way too far over the ball! Maybe he should get a lesson and not a fitting.

    I’ve seen quite a number of golfers with strange putting techniques and lots of confidence hole out from everywhere. I do believe putting is something personal, subjetive and the right technique works fine to become an average putter.

    Good putters are above all confident on the green and they repeat the same swing over and over.

    While this is a glorified commercial posed as journalism, I think it’s good information. I just got fitted for a full bag last month after 4 years of playing. The putter info was most helpful. The fitter bent my putter so that the ball rolled pure off the face without any skipping. And told me that I need a 45 degree too hang mallet. Good luck finding those!

    Get fit. Anywhere that is reputable.

      Brian – Ping makes putter that fit straight all the way up to strong arc (large rotation putters). Technically a mallet with that much toe hang will very hard to produce due to the CG of the clubhead being further from the face.

The Wedge Guy: The 5 indisputable rules of bunker play



I received a particularly interesting question this week from Art S., who said he has read all the tips about how to hit different sand shots, from different sand conditions, but it would be helpful to know why. Specifically, here’s what Art had to say:

“I recently found myself in a few sand traps in multiple lies and multiple degrees of wetness. I tried remembering all of the “rules” of how to stand, how much to open my club, how much weight to shift forward or back, etc. based on the Golf Channel but was hoping that you might be able to do a blog on the ‘why’ of sand play so that we can understand it rather than memorizing what to do. Is there any way you can discuss what the club is doing and why you open the club, open your stance, what you’re aiming for when you open up, and any other tips?”

Well, Art, you asked a very good question, so let’s try to cover the basics of sand play–the “geometry and physics” at work in the bunkers–and see if we can make all of this more clear for you.

First of all, I think bunkers are among the toughest of places to find your ball. We see the tour players hit these spectacular bunker shots every week, but realize that they are playing courses where the bunkers are maintained to PGA Tour standards, so they are pretty much the same every hole and every week. This helps the players to produce the “product” the tour is trying to deliver–excitement. Of course, those guys also practice bunker play every day.

All of us, on the other hand, play courses where the bunkers are different from one another. This one is a little firmer, that one a little softer. So, let me see if I can shed a little light on the “whys and wherefores” of bunker play.

The sand wedge has a sole with a downward/backward angle built into it – we call that bounce. It’s sole (no pun intended) function is to provide a measure of “rejection” force or lift when the club makes contact with the sand. The more bounce that is built into the sole of the wedge, the more this rejection force is applied. And when we open the face of the wedge, we increase the effective bounce so that this force is increased as well.

The most basic thing you have to assess when you step into a bunker is the firmness of the sand. It stands to reason that the firmer the texture, the more it will reject the digging effect of the wedge. That “rejection quotient” also determines the most desirable swing path for the shot at hand. Firmer sand will reject the club more, so you can hit the shot with a slightly more descending clubhead path. Conversely, softer or fluffier sand will provide less rejection force, so you need to hit the shot with a shallower clubhead path so that you don’t dig a trench.

So, with these basic principles at work, it makes sense to remember these “Five Indisputable Rules of Bunker Play”

  1. Firmer sand will provide more rejection force – open the club less and play the ball back a little to steepen the bottom of the clubhead path.
  2. Softer sand will provide less rejection force – open the club more and play the ball slighter further forward in your stance to create a flatter clubhead path through the impact zone.
  3. The ball will come out on a path roughly halfway between the alignment of your body and the direction the face is pointing – the more you open the face, the further left your body should be aligned.
  4. On downslope or upslope lies, try to set your body at right angles to the lie, so that your swing path can be as close to parallel with the ground as possible, so this geometry can still work. Remember that downhill slopes reduce the loft of the club and uphill slopes increase the loft.
  5. Most recreational golfers are going to hit better shots from the rough than the bunkers, so play away from them when possible (unless bunker play is your strength).

So, there you go, Art. I hope this gives you the basics you were seeking.

As always, I invite all of you to send in your questions to be considered for a future article. It can be about anything related to golf equipment or playing the game–just send it in. You can’t win if you don’t ask!
