There seems to be a debate in golf instruction concerning old-school versus new-school teaching. I think the discussion is mostly academic and largely a product of the golf blogosphere, which is in reality an amalgam of disparate ideas, the sum of which can lead to more confusion than clarity. The point is that any good teacher of the game should be a student of all the new science while striving for the simplest ways to convey the data to their students.

Imagine taking a golf lesson that removes any doubt about what your golf swing is doing. Imagine having the confidence to know exactly what to work on. Even picture a scenario where you can virtually see yourself on every swing. It’s a reality with a new technology called GEARS golf.

GEARS, which stands for Golf Evaluation and Research System, was launched at the PGA show in 2014 after five years of development. It’s a full swing, club and body-tracking system used by PGA pros, club fitters, teachers and equipment manufacturers to measure tiny nuances in full 3D from address to follow through. Unlike Trackman and FlightScope, it’s not a Doppler radar system; it’s a motion-capture system built on the same technology used by biomechanists and filmmakers. With GEARS, eight 1.7-megapixel cameras run at 360 frames per second creating measurements as fine as 0.2 mm. There are no wires, and it works for any golfer and any golf club.

“GEARS is the most accurate golf swing tracking system on the planet,” says Michael Neff, Director of GEARS Sports. And I believe him.

A typical indoor setup of Gears.
A typical indoor setup of Gears. The system can be transported inside and out and from course to course.

In my many years of teaching our game, I have always found it necessary to ask three simple questions:

  • What is the ball doing?
  • What did the club do to influence the ball?
  • What did player do to influence the golf club?

GEARS is the only system I have ever found that answers all three questions with absolute certainty, thanks to its ability to analyze over 600 images per swing in less than a second. In the videos below, you can see just a few examples of what the system offers.

Club Head Speed and Club Face Contact

Attack Angle

Club Head Path

Some golfers, and even some golf instructors might consider this too much detail. Why would anyone need this much information? Well, you may or may not… but why not have access to all the accurate information you can and then simply take from it what you need?

You can use the info GEARS provides for a thorough club fitting, or find the things you need to work on in your swing. Remember the avatars you see in these videos are of YOU swinging the golf club. The data gathered is the true trace of the arms, body, wrists and all parts of the golf club throughout the entire swing.

Many of you who read my GolfWRX articles know me as a non-technical teacher, and to a large extent I do try to simplify my instruction and condense the information as much as possible. But non-technical is not to be confused with unscientific or irrational. Everything any good teacher does must be based on the latest research in the field and GEARS represents that horizon. Three-dimensional analyses are at the forefront of where teaching and fitting is right now, and to disregard it is a disservice to our students. What I particularly like is that GEARS can offer me measurements, not estimates, and that is the essence of the this cutting edge system.

There are currently 32 GEARS systems in the United States. Systems sell for about $32,000, and golfers can book time on a system for roughly $200-$250 for 1-2 hours. Email info@gearssports.com to learn more.

  1. I have used the GEARS system and it has some extremely good information for clubfitting as well as instruction. For clubfitting, it has the best information for tempo, transition, release and face contact (of course the other important stuff like club/ball speed, smash, launch, spin and attack angle). Trying to figure out the exact combination of shafts that will make our fitting sessions even more productive before we pull the trigger on this system. Reason is that it takes a while to calibrate the shaft/head combination so it could be cumbersome in a fitting if you do not have the right combinations to begin with. Love the system though…of course I am a techno geek that has seen the evolution of clubfitting and this is the next great thing. Great job GEARS!

  2. Hey Dennis,
    Good stuff as usual. I am all about the technology in the game also. How the info is dispersed to the student is the key, bird like portions work best I have found.
    Trackman has parameters that never see the light of day at our place and Gears is no different. Most of the time I do not even show the numbers, only discuss them so they can focus on the task at hand. Unfortunately there are a few that are very traditional when it come to the sport and like the “Keep it simple stupid approach”. Keep on writing and I will keep reading Pro.. Best wishes and good health!

  3. At what point is the golfer overwhelmed with information?
    How does he/she know what part of the swing needs to be “fixed” first?
    According to this system what is a “correct” swing?
    What would this system tell about Jim Furyk, Arnold Palmer, Lee Trevino and Chi-Chi Rodriguez swing?

  4. Dennis, great, great. Article. Tech has improved my game more in the past 6mos than anything in the past 15years. Understanding the physics and biomechanics behind the golf swing is truly important to actually implementing on the course and ultimately developing confidence and consistent feel. Plus, now i know exactly why a shot goes astray and how to fix it.

    If you could also do one on hand path for drivers and irons that would be awesome.

    Finally, forget the trolls here, they are just intimidated about where to start to eliminate their own ignorance.

    • Wipe you nose again, you missed a spot,,,,,,,,
      So we are not to respond nor comment on these articles? And if we do all we should do is compliment and praise?
      Reality check,,,, $200-$250- that’s what many golfers spend on golf a month, they are also the ones who are keeping many golf courses from going under,,,,

  5. So this GEAR thing tells me that my angle of attack is 3.75 degrees too steep, that I am coming out to in by 3 degrees and the face is open 1.5 degrees, but the ball is going straight or baby fade ( I have in fact a slight out to in swing and my miss IS a baby fade),,,,,,,,,

    Now what !?!?!

    • 3.75 too steep compared to what? 3 degrees out-in with 1.5 open hit in the middle of the face would be a baby fade? What is your question? if your ball flight belies path/face relationship, there’s a good chance your hitting the toe in this case. It’s known as horizontal gear effect.

      • Maybe I should explain my post a little better,,,,,,,,,,,,, Let say I got all that information from the system, now what am I supposed to do with it?!?!? How do I correct it?!?!? How do I know its fixed?!?! How do I know when am off again ?!?! There is way too much info being fed to golfers, I have read posts here of people saying how they lowered their RPM’s by 200 simply by buying a new $300 shaft,,, too much emphasis on numbers and not on feel,,,

        But I could be wrong

    • The professional giving you your lesson on this will show the most important issue(s) AND explain why you should correct them – after all, that’s why you’re there – hopefully not just to do an MRI on your golfswing and then do nothing to fix the problem it found.- Just as if only using good video camera’s. They SHOULD while reviewing your video
      with you, be explaining both sides ; WHAT
      you DID to get to a bad – say ‘top position’ & how to
      change the move and get to a better spot, WHY the less than good position you ended up in now affects the next move you (can – or now must HAVE to) do The ability to make an easy repetitive swing – or not – is always a byproduct of what happened one or two moves before…

      I have wireless/markerless 3D Biometric
      motion analysis and use maybe 40% of all the areas it measures, and it’s awesome for actually quantifying things like shoulder & hip turn, weight distribution, weight shift spine tilt, etc…I can show you YOU – not a stick figure – and say if you’re shoulder’s only turning 69 or 72 degrees we can work on getting it to 85, then 90 (unless a physical limitation is present)….
      Not all brilliant people are good teachers (Foley?)
      A good teacher makes it flow and make sense as part of making his case why the student should change, needs to change OR absolutely HAS TO change – if they want to improve, stop hurting, or reach their potential.

      Remember, you came to us. If someone has this and can’t give you a full and easily understood (some numbers included too) analysis of your swing, what you’re doing well & not, what needs to change to meet your goals and how the two of you will go about it by the end of the first 15 minutes – including practice swings & some warm up shots, they’re too lost in their tech stuff and not focused enough on the human next to ‘em

      I’ll bet your buddy Parson will buy one :)

  6. A major concern with this system are the sensors placed on the shaft and club-head. The sensors are not weightless, producing data that is not entirely accurate. This also increases swing weight to a considerable factor, having tried GEARS last year.

    • Swing weight changes 1 step and head markers weigh 1 gram each and shaft clip is 8 gram

      We have had no negative feedback from any of the tour players that have been on the system

      This only way to accurately find the center of a marker is if it’s a ball. This is how we find the center to within 00.2mm

      Small price to pay for most accurate tool to measure the body, they wrists, grip, shaft, head and face. Oh and all at the same time…

  7. I wrote this article to inform you that there is currently a technology called GEARS which offers the many things I described, just as there is, say, an iPhone 7 you can now buy and several new apps you put on that phone. Any and all of the latest technology is an option, a choice that we, the consumers, make or NOT make. In fact golf itself is an optional hobby. No one is suggesting you buy it, simply saying that it’s there. As for the myriad features, i suggest you take as much or as little as you like. If you’re looking for one particular area of your club or swing to correct, GEARS will identify that area. Forget the rest. Also, the technology is quite obviously not a home product to be set up in ones garage, just as a heart monitor is not meant for your bedroom. That’s why there are professional studios that provide this service on an hourly basis. Thx.

  8. For crying out loud, just hit the ball the best you can 3 times and hopefully have a look at par!!! All these gadgets and gizmos, fitting carts, 300 shaft options, 1300 grips to choose from, lasers, 36 brands of golf balls, etc.!! Just step up to da tee and hit it, find it, hit again, again, and pull the flat
    stick!! I’m up to here with all the nonsense already.

  9. Better data is always better. Especially as it eventually filters down to things that a greater amount of people can afford and use. Put this on a grass driving range in which I can watch the real flight of my ball and I’m interested. Combine this with a swing coach that excels at getting one into their zone as their swing and technique is being evaluated and you have a winner (I had the experience of this last week – awesome session). My only issue with a lot of this technology is the presentation of the images and video from a 3rd person perspective. The last I checked I swing the golf club from within the swing, not outside looking in. It is from this point of view one needs to understand the swing, not from a camera person looking through a view finder. Granted, short of projecting a holographic video around myself, I have no simple answer to the issue myself.

  10. Yeah? How much does the whole system cost? And don’t give me the PGA discount price, we know they get to lease this stuff at big discounted prices. What would it cost for a normal person to buy one for his or her home?

    • Enough is enough…consider this the first gen Laser disc player of over the top crazy shit HUMANS can’t possibly need. Wait 6 years and it’ll be half the hassle and half the price.
      I LOVE TECH…Got Trackman and between that and my SwingGuru Pro most current editionn I can already produce too much ‘close enough for gov’t work’ OR SCRATCH GOLF data (within 2-3 degrees of measured spine tilt, shoulder tilt each arm and leg flexion, shoulder turn, hip turn head movement blah blah AND dead on
      accurate live time weight distribution & shift withnd with NO WIRES. I can live without all that because my 3 IDS
      cameras running 2@225fps (down the line & face on) and
      1 @ 450fps showing the clubhead CLEAR AS DAY from last 4 feet of downswing can see path, face rotation exactly where ball is struck and any deviation or head rotation from force of impact… The visualization of THE REAL CLUBHEAD AND PLAYER is 109 times better for the student to see amd understand than all the numbers we get from Trackman (which however is indispensable for driver and shaft fittings) but when conpared to the High Speed HD cameras bo where near as helpful for lessons – except for the rop 5% of my competitive players swinging >105.

      The “Normal” person who’d buy this “for their home” already has the best 40K “Full Swing” box simulator and 2 sets of PXG’s – staff bags too. One for home and one for the club….

      No one – maybe Woods or Pelz would buy this monstrosity –
      for their ‘home’ – but then again, they’d end up getting it comp’d.

      nothing beats good clear multiple high speed cameras & some foot-rot spray on the clubface

    • ENOUGH already! I LOVE TECH…This will be great for fine tuning robot golfers for combat – once they evolve from just smashing each other up on ‘Battle Bots’…

      I can produce way too much biomechanical data now with my Swing Guru Pro 3D WIRELESS & MARKERLESS system. IT gives more info than a human player OR COACH needs. The latest gen produces spine tilt, shoulder tilt, stance to the cm. Real time dead on weight distribution & full motion shift – without pressure pads, shoulder & hip turn, head motionn arm n leg motion.. and more.blah blah numbers no one needs. I can show tilt n turn accurate within a couple degrees – “close enough for Government work” – OR SCRATCH GOLF. My Trackman, while INDESPENSABLE for driver & shaft fitting, spits out more numbers than all but my top 5% of competitive players need.

      Where as my 3 High Speed HD IDS camerasn 2 running @ 225 fps (face on & down the line) and the 3rd dedicated over the 4 feet od clubhead approaching, rotating into and striking the ball give CLEAR AS DAY images inch by inch SHOWING THE REAL PATH, FACE ANGLE & IMPACT with the ball.

      These visuals of the real human I’m teaching, his/her belly or boobs getting in the way, their actual hands and glove and their real club – are FAR better than all the numbers all the other stuff combined yields.

      As far as the “NORMAL GUY” (?!) Who’d buy this monstrosity “for their home”? – They already own the 35K FULL SIZE BOX “Full Swing” Simulator and probably have two of those curverd XXXXHD 10K 60″ Samsung TV’s and bar in their simulator room…along with 3 full sets of PXG’s -one for home, one for the club & one to show off in their office. They could give a crap how much this costs.

      The first two people to order one will be Woods & Pelz – and they’ll probably get it comp’d.

      nothing beats good HS cameras & a little foot-rot spray on the clubhead

  11. The cover photo of Nick Price is not a true GEARS session because he is not wearing a suit with optical markers (little white balls) on it nor does his club have any optical markers. The optical markers are placed all over your body at every strategic point and joint to capture all information perfectly. GEARS is an optical tracking system and without these markers the cameras and software cannot return the needed information. I have used this system and it is truly impressive. My instructor was able to clearly show me my issues and we were able to build a plan that made a great deal of sense to fix my problems. I will not bore you with how bad my positions were during my swing, but it clearly opened my eyes to what was going on in my swing and the compensations that I was needing to make due to being in those bad positions. After the three day golf academy the before and after on GEARS were dramatic. Very impressive

    • Here’s the answer to the Nick Price observation from Mike Neff, GEARS director.

      “If you look closely there are markers on his club

      Gears has the ability to do body and club or just the club.

      Nick price was looking for answers as to why his driving was suffering. Gears answered those questions where no other tech could. It’s an amazing story. One of the best golf days of my life”.

  12. This is exciting technology. I admit, I probably over analyze numbers and technical info for my golf swing. However, I think in the right hands, this is perfect. If an instructor has this info, he/she can diagnose why something is happening and focus on the pieces to fix flaws. They know what info is important and what isn’t. The info in amateur students’ hands may cause them to go crazy and not be focused on the building blocks. I can’t wait to see the list of facilities. Hopefully one around me.

  13. As a data geek, this has me pretty excited. The question to me is how much of this extra data is actionable. Data is great if it helps you make a decision but if it’s mostly noise it’s just more of a mess that can cloud our heads when setting up for a shot.

    • Chris, that’s exactly the point I’m making…actionable data is working data or that which is relevant to an individual. What GEARS provides is ALL the data, much of which you may well be executing within a functional range. Its a “take what you need” kinda thing…The beauty again is MEASURED not estimated. Thx for interest.

  14. I’m all for technology that shows what’s really happening in your swing, not what some old time golf coach THINKS is happening. What this will do(eventually) is make golf instruction more consistent, force incompetant golf coach to learn or lose students, and simplify golf for all of us.

  15. Finally, a potential technology that could bring the cost of trackman down to moderately out of reach, instead of, maybe when I’m 75 I could afford it, when I no longer need it.
