We are all capable of hitting amazing golf shots, yet it is those mind-numbingly bad shots that ruin our day and erode any measure of confidence that we may have been hanging on to. The question we all would like to know the answer to is – why? Why was that shot so far offline when I’ve been hitting the ball straight just about all day? What is the primary cause of my inaccuracy?
My experience is that most golfers tend to look in the same place to find answers to their problems. Just like husbands tell their wives on every bad shot she might hit – “You lifted up!” Well, so to do we tend look towards the same area as a cause for our bad shots. Talking with my students it appears that far too many golfers are of the belief that bad shots are caused by a swing that was suddenly over the top or under plane – in other words the clubpath was different and that’s what led to the offline shot. This is even a favorite for the golf commentators on Sunday afternoons – if a golfer hits a shot left coming down the stretch you are very likely to hear Nick or Johnny chime in with, “Well, he came over that one…”
Teaching with TrackMan has taught me that most golfers’ inaccurate shots are caused by one of two factors:
- An open or closed face at impact
- Or an off center strike (heel or toe)
Golfers tend to be fairly consistent with their clubpath. Keep in mind that this is a general statement and not all golfers are consistent, but my experience has shown that golfers that work at their game tend to have a good measure of consistency when it comes to the direction their clubhead is travelling at impact – clubpath. It may not be an ideal path or what they are looking for, but consistent it is!
Consistency to your shot pattern comes from passive hands through impact and a predictable point of contact on the face (even if it’s not in the center!)
Please note that there is a mistake in my video! The face does not determine where the ball finishes, but rather where it starts! Sorry about that….

I was recently contacted by Swingbyte and asked to test their device to see how the data it generated held up against data generated by TrackMan. Please remember this is not a contest and I am not saying that TrackMan is perfect (I’m not sure there is such a thing), but I do believe TrackMan is the benchmark when it comes to reporting club and ball data in golf and I was interested to see how a $150 swing aid held up.
Swingbyte is a swing analyzing device that attaches to your club just below the grip and sends data to a mobile phone or tablet via Bluetooth. With a price point of $150 it provides a tremendous amount of data and sifting through the information on the App might be a little confusing at first, but with patience you will eventually find what you’re looking for.
Having used TrackMan for a long time one of the notable things I’ve found with passionate golfers is that the direction the clubhead is travelling through impact (attack angle and club path) is generally quite consistent. When testing/comparing other devices to TrackMan, whenever I see a dramatic change from one swing to the next in either attack angle or club path numbers a red flag goes up. With the Swingbyte I hit pitching wedges, 7 irons and drivers and I primarily keyed in on club speed, attack angle, club path and face angle. Here are my ratings out of a possible 5 stars:
If you purchased the device to simply know your club speed you are ahead of the game. It is important to enter detailed specs from each club into the App, but once you’ve got that done the feedback is surprisingly accurate. All the numbers I saw were within 4 mph of where TrackMan reported. (4.5 out of 5)
It is important to know that TrackMan and Swingbyte report attack angle from slightly different portions of the swing and thus differences should be expected, however I thought the device did a fairly accurate job most of the time. With the irons I felt the numbers indicated were close enough to “actual” in order to be actionable. It did seem that attack angles with the driver were a little too ascending. Their were also a few crazy numbers reported, but as you use the device more you’ll easily be able to recognize any outliers. (3.5 out of 5)
These numbers were a long way from what TrackMan was reporting and I would not put too much into this particular parameter. For example with the driver TrackMan reported my average club path on multiple shots was 0.2 degrees out to in, while Swingbyte indicated that every swing I made was from in to out with a range of 1.7 degrees to 13.6 degrees from in to out. (1 out of 5)
Even with TrackMan I seldom give much credence to the reported face angle as it is too easily influenced by off center hits and I most often use the reported number to determine where the ball was struck on the face. The original Swingbyte reports face angle at impact relative to where it was aligned at address. Assuming you have aligned the device on the club correctly, start with a square clubface and no twisting occurs, you might get an actionable reading – otherwise, I’d move on. (1 out of 5)
The problem Swingbyte has faced is that it could not latch onto a target – it only registered where the device was aligned at address. This means that any data regarding club path and face angle is based around where the device was aimed at address. The Swingbyte 2 addresses this issue. Founder and CEO, Alex Pedenko had the following to say:
You can now point your iPad and it will know what your target is and figure out all the numbers based on that. So now you have true, accurate numbers about what you did, not just in general but relative to the target line, relative to where you want it to go.
I am hoping that these upgrades will make this already useful device even better. While the device is not perfect (what is?) and should not replace quality coaching I feel that with a few practice sessions any golfer can start to gain a better understanding of what they need to do in order to make progress.
We should all be looking to spin the ball around the greens. Which of the current crop of wedges will give us the best chance to do that? If you have read any of my previous research on wedges you will know that friction between the face and the ball plays a huge role, not only in generating spin, but also in lowering trajectory – both vitally important for control.
The most important part of the clubface of any wedge is not the grooves, but the texturing of the flat areas between the grooves. Keep in mind that the primary purpose of grooves is to channel “matter” away from being caught between the flat areas and the ball – they are not in place to create spin. When you look carefully at the flat areas between the grooves of your wedge you should see some fine milling which looks like corduroy to me. Most club manufacturers will mill the clubface of their premium wedges and it makes a massive difference to the control and ball flight.
The idea behind the test was to see which wedge generated the better grip between face and ball. I had four very new 58 degree wedges available for the test:
- Titleist Vokey SM4 with a DG Spinner shaft – conforming grooves with standard mill pattern on face
- Ping Gorge Tour with a DG Spinner shaft – conforming “gorge” grooves with standard mill pattern on face
- Callaway X Series Jaws CC with a stock steel shaft – additional conforming grooves with no apparent milling on face
- TaylorMade ATV with a KBS shaft – conforming grooves with two-way mill pattern on face
You may notice that the wedges had differing shafts – I obviously would have preferred to have had all the clubs built to the exact same specs, but that was not feasible for this test. Apologies to all Cleveland Golf fans – would love to have had a Cleveland wedge in the mix, but did not have a new version. I had four golf professionals each hit four shots with each wedge. All shots were hit off a mat in order to limit friction being interrupted by matter being caught between face and ball. Titleist ProV1 golf balls were used and each shot had to land somewhere between 40 and 60 yards (ideally at 50 yards). The clubface was cleaned often even though it never appeared to need it. The “normalize” feature on TrackMan was off.
Here are the results:
- ATV 7365 rpm average
- Vokey 7210 rpm average
- Gorge 7193 rpm average
- Jaws 7163 rpm average
As you can see the ATV wedge led the way in generating the highest spin of the four – albeit by a slender 2%. If I was a betting man I would have bet the ATV would generate the most spin as I have always loved the two-way milling treatment on the face. I would also have placed the Jaws wedge at the bottom of the pack, as no matter how many groove edges come in contact with the ball, there is way more flat surface area contacting the ball and it should be milled.
If you do take one thing from this research let it be the following: A fresh wedge with a clean, milled clubface will allow you to generate more spin and a lower trajectory – both important factors in controlling your golf ball around the greens.

There is so much complex information out there regarding the Ball Flight Laws – a ten second Google search yields enough confusion to get my head spinning for a month. The “old” or “new” ball flight laws, Dr. Wiren, TrackMan…..who or what should you believe?
In light of Dr. Einstein‘s insightful quote I am going to give this touchy topic my best shot and try to keep it as simple as possible. Please don’t check out! This is important information for any golfer to comprehend, so bear with me and you’ll gain a far better understanding of why your golf ball reacts the way it does.
There are only four factors that influence ball flight when clean (not necessarily solid) contact is made between a golfball and a clubface.
The faster the clubhead travels the further and higher the ball will travel – generally with more spin. Compare a chip (slow speed) with a pitching wedge vs. a full swing (faster speed) with a pitching wedge…simple enough.
Orientation is a fancy term that refers to where the clubface is angled. Keep in mind that the face angles both left or right or up or down – left or right being an open or closed face and the up/down variable (although hopefully never down) referring to the loft imparted at impact (dynamic loft). The face angle largely determines where the ball launches – left or right of the target and at what angle relative to the ground. A good general point to remember is clubface (for the most part) = launch.
Once again the direction the clubhead travels relative to the target line at impact – left or right (clubpath) and up or down (attack angle) – plays a role in determining ball flight. A lesser role than the clubface, but a role nonetheless. A good general point to remember is clubpath (for the most part) = curve.
Centerdness of Contact
This is a big one and something the vast majority of teachers and golfers tend to underestimate. Most golfers strike the ball on the sweet spot far less frequently than they think . I often see golfers that swing for a draw, yet strike for a fade – in other words they have a clubpath that is in to out, yet hit the ball slightly out the heel which leads to a fade. An off center point of contact on the face leads to gear effect, which overrides or reduces the effect the face orientation and clubhead direction have on ball flight. This factor plays a bigger role than most realize – watch out for it. And the best way to do that – a spray of Dr. Scholl’s foot powder.
Here are a few simple factors to understand and remember:
- The ball launches primarily in the direction of the face – varying degrees of up and either left or right.
- Given a centered hit, clubpath leads to curve. With the curve being away from the clubpath.
- Hitting down does not increase spin, and conversely, hitting up does not necessarily reduce spin.
- Heel hits encourage fades or reduce hooks and toe hits encourage draws or reduce slices.
- The more you hit down on the ball, the more you will swing in to out and the more you hit up on the ball the more you will swing out to in.
Now that you’re finished reading shoot back up to the top and read again. This is vital information to assist with your understanding of of how your golf club “communicates” to your golf ball.

Thanks for reading and feel free to fire away with any questions you may have…..
I recently stumbled onto an interesting tidbit whilst working with a young professional on his wedge game. It was early in the morning and we had been hitting beautiful 50 yard pitches the afternoon before and suddenly he could not get the ball to launch low enough with the spin rate he had been generating the day before. Now as you may know I’ve tested almost all there is to test in regards to a 50 yard wedge shot and of course I had looked into the effect of water interfering with the friction between the face and the ball. One problem – I had tested a wet club striking a dry ball. My results from the earlier test showed very little difference in launch and spin when there was water involved and I had since adopted that belief.
As I watched the young pro struggle to lower his launch in the morning dew it came to me – there was a difference between a wet club striking a dry ball and a dry club striking a wet ball! I had to run the test again.
I had to be very careful with the test in that I needed to use the same club, my 54 degree sand wedge, in very controlled conditions, with golf balls that were consistent. I used brand new Titleist NXT Tour golf balls and made sure that I cleaned the grooves and clubface off between each shot. I attempted to hit each shot to carry 50 yards flat and hit eight shots for each portion of the test. I removed the two shots that had the lowest spin from each portion. With the help of my TrackMan here are the results:
Wet club and dry ball:
- Launch angle was 27.8 degrees
- Spin rate was 5463 rpm
- Height was 26.5 feet
Dry club and wet ball:
- Launch angle was 30.1 degrees
- Spin rate was 5291 rpm
- Height was 28.4 feet
Dry club and dry ball:
- Launch angle was 25.4 degrees
- Spin rate was 6603 rpm
- Height was 21.2 feet
The interesting thing in looking at the trajectory chart is how much lower the dry club and dry ball (purple) shots flew. Clearly there was more friction between the face and ball which led to a lower launch with substantially more spin. The dry club and wet ball (yellow) sample flew the highest as the water on the ball greatly decreased friction which led to higher launch, due to slippage and thus decreased spin – certainly not the optimal shot.
The interesting thing when comparing the wet club/dry ball versus the dry club/wet ball results was that the spin and launch were better when the BALL was dry. This was due to the water being forced off the clubhead and into the groove channels during the motion of the swing. Not to mention that the air dried the face during the swing too.
Moral of the story – always clean the clubface (unless it has sand on it) and dry the club and ball when possible. If you happen to have an early morning tee time and you’re a dew sweeper, don’t plan on hitting any low spinners! The drier the ball and club, the better the friction and the better the quality of shots you will hit.
