This was a fascinating video. I think this ‘experiment’ would be more valid if you got numbers from an outdoor range session on real grass as a control and then went through these different indoor scenarios and with different types of mat densities.
Indeed. And see 1996 PGA Championship winner Mark Brooks on the following video at the 2nd Swing Golf channel: OLD vs NEW Golf Irons Testing with Mark Brooks
Great content! I'm an outdoor player most of the time, but go to indoor launch monitors to "check my numbers". This seems super useful. Also could be very valuable info for digital golf league competitions.
I play forged irons and when I have to hit off mats, especially in colder months, I have to adjust my lie angles due to the lack of “give” in mats compared to turf. Great video guys!
@10:00 I've been using a Divot hitting strip with a short pile, it allows me to get under the ball in order to get it higher on the face. It definitely makes a difference with spin for me. Thanks for another great video!
Very timely video. I just got fitted indoors and felt like I was striking the ball perfectly with a 7 iron but the revs were down near 1000 to 1500 RPM from what I expected. Very similar results to what Matt was seeing here. Hmmm.
This is great! Good job dude! This explains a lot. I have been wondering so much why I lose 6 meters carry with my 7 iron on course. This explains it. Thanks m8 ❤
Amazing find! I went from 4951rpm to 6380 by putting down a little soapy spray....in back to back shots!.....I was about to go on a hunt for spinnier balls, great job!
Another interesting video. So many cool new golf videos on UA-cam, like the grip pressure videos. Bear in mind, when you hit on a range mat that there is far more bounce effect happening than on grass
Interesting result. So, spin is created by shearing force on the golf ball cover by the club. A possible explanation would be that the friction of the mat adds a counteracting shear force on the ball during the contact duration where the ball is moving across the mat (very small distance). With a wet mat, this counteracting shear force is less, so the net shear force on the ball is greater.
Very cool test! I did read/watch a video talking about the deflection of a club in dirt versus a mat. So, because you get deflection up off mats, you would get lower spin…on real turf, your club would actually increase in AoA as it hits the turf as it digs in to take a divot…they used very high speed cameras to show the difference. Even though the ball is only on the face for about 1/2 inch, when struck properly, you would still get the downward deflection…in addition, balls hit slightly fat would fly much better than off turf, and because of the upwards deflection off the mat (which Trackman and other LMs have trouble picking up) you’d get lower spin…to hit it higher off the clubface, just use a tee!!!
This is the kinda research we need! I much prefer grass driving ranges, because I never play golf on fake turf, makes sense. I subbed Turf vs Grass spin rate video when?
Great experiment and finding! Congratulations. This also explains why Ian and the club champion guys were baffled when they were testing wedges and found more spin with a wet ball which they didn't understand
Correct Joe. What TXG didn't realise is that it wasn't actually the wet ball that created the greater spin. Because they sprayed the ball in situ, they also wet the turf around and under the ball, in the same way AJ has done here. If they had sprayed the contact point and back of the ball only, and kept the turf dry, it would have resulted in the lower spin they were expecting.
That was great, never though it would be the mat grabbing the ball. I always thought mats reduced the spin by about 1000 rpms, but from that it appears to be nearer 1500. Nice work!
Great stuff. The only thing I would possibly add is that maybe the launch monitor has a difficult time reading the spin because of the dry mat. Meaning that the ball may actually be spinning the same amount and the dry mat is not actually decreasing the spin, but the launch monitor reads and error. I did find it intersting that the launch angle on the wet mat was the 2nd lowest launch angle and only second to the 'steep swing' launch angle. Again, great stuff. Thank you for the content.
Spin is the same if I hit the ball the same, but I tend to release earlier on mats. However, this is a "me" problem, not a scientific problem. Great video, love content like this!
This is very interesting for indoor simulators. It would also be interesting to see the difference between mats vs real turf, and of course the length of turf from tight lies to rough. I never could understand why people pay $$$$$ to get fitted for irons off of mats??? Pretty rare when one is hitting off a mat when playing on a real course.
Very interesting video. I will say I have hit off different mats at different stores and the one that has very soft mats high pile mats I constantly have a higher strike and lower spin with the irons so I think there are cases that can effect it.
Great video thanks. I have a home studio and always suspected that the spin was a bit low. It would be nice to see some control data by hitting outdoors first.
The general consensus on google is that mats cause higher impact in the face and higher launch/lower spin. Makes me wonder if it takes more impact tape type comparisons.
850 x iron number is the new formula, according to 1996 PGA Championship winner Mark Brooks on the following video at the 2nd Swing Golf channel: OLD vs NEW Golf Irons Testing with Mark Brooks
Yeah, with more traditionally loft clubs the old formula may have been a rule of thumb but newer irons promote higher launch and less spin thru loft jacking and lower CG.
@@atxrich Indeed. I learned this from 1996 PGA Championship winner Mark Brooks on the following video at the 2nd Swing Golf channel: OLD vs NEW Golf Irons Testing with Mark Brooks
Formula really is irrelevant because each players speed, attack angle, etc are different. There's just no way you're going to get a player spinning an 8 iron 6400 RPMs with a 60 mph vs a player with a 90 mph swing.
After watching all of this one, now I want to go ho test my FiberBuilt, lol I had 9700 on my DIY 9 iron chipper yesterday I wonder what the grass series does wet?
You nailed it when you said people don’t want to hit down on mats and wreck a shaft. The more you hit down on the ball, the more spin you create, not being able to take a divot and finish with the head penetrating the turf reduces spin as the synthetic turf will not allow it.. hence why when the ball was hit steeper vs. shallower on the mat, the only difference was stopping distance.
That explains the theory that on wet courses, the ball goes higher and spins more. Also shorter here on the PNW coast by a club or more. That was some fine ball striking! Wow!!
Wet ball is essentially a flyer lie and you get less spin, but, yes, higher launch. It should make most of your clubs longer, not shorter-but long irons might get shorter due to a lack of spin.
@@johnbrodnik839 it’s probably almost all due temps assuming altitude is the same. I think rule-of-thumb is about 2 extra/less yards for each 10 degrees above/below 70 degrees-so like nearly a club if your play in 100 degree desert versus 60 degree PNW.
I bought some tees that are designed to be used with mats to give you better spin numbers. I haven’t tried them yet. They are very short, maybe 1/8” or so.
wonder if you tee'd it up to get it higher on the club face but then it takes the mat out of the equation... Would be curious to get a high rough mat and do the test again. Even wet that high rough.
Had that tee idea as well but like you said it would remove the mat from the ball interaction completely. Would like to try some other mats and maybe wet and dry grass.
I think it depends on how you strike the ball - my numbers are basically identical comparing mat to a decent fairway when i take my launch pro to the course
Each mat is different especially depending on the player. You can hit a little fat on those mats and still get away with it, bounce off the turf and get a nice high launch low spin shot. Can't get away with a heavy shot on grass. Also with the fiber built mat which uses bristles , I see a bit more accurate spin compared to outdoors because the bristles allow the club to continue traveling downward through the strike similar to what a divot does on the course. The bristles also hold the ball up higher than on a typical mat so its really easy to miss higher on the face.
Check out our numbers here. The hitting mat I use is 1 inch tall bristles and the putting surface Matt hit off was extremely low pile. Same exact average spin for both.
It also depends on how you hit the ball, my friend who is really steep and hit the ball low on the face, the mat reduce his spin by 2000 for his 7 iron. Crazy difference
Not just mats but old worn out range balls. Occasionally I'll bring along a few still good used balls and hit them on the range and the ball flight and distances are very different.
Makes absolute sense. That's why when we practice on mats and get there on the course things are somewhat different. And there are so many kinds of turf. Go figure.
This info is going to make indoor public ranges make a new “no spray bottle zone” and makers of curtains on overdrive, keeping up with spotted curtains syndrome 😅
Could have just asked Bryson or Phil :) Guessing the turf gives a little at impact so higher on the face and so less spin. If I have a full shot on tight fairways I'll expect more spin, lower flight, and shorter carry.
Your spin is the same with the steeper angle of attack because your spin loft window didn’t change much (difference between AoA and Dynamic Loft). You had 2° more AoA but you also decreased Dynamic Loft by 2° so your spin loft window is the same as regular swing. Also, I believe we should mostly fit based on launch, ball speed, apex, and descent angle vs focusing on spin for full shot irons. A full 8iron shot that has 8000 spin but it’s going up to 50 feet isn’t going to stop on a green. As long as the 8iron has enough descent angle, 6000 spin should be fine, as descent angle is doing most of the stopping on full iron shots.
The cause for the lower spin indoors off mats is generally a result of the wider margins for error the mat provides for “fat” or “heavy” shots. Most recreational golfers incorrectly bottom their irons out behind the ball vs pros that correctly hit ball first and their irons bottom out after the ball. Hitting a fat shot off a mat will result in helping an open face player close the face (lowering spin) as well as de-loft the head (lower spin) resulting in the skewed data you generally see in indoor data from recreational golfers. It’s important for a fitter or teaching pro to understand the difference and have systems in place to be able to identity the root cause of the data they are seeing.
This video shows it's totally the mat, not variations in the strike. Matt hit every ball, except one thin shot, great. Could not have asked for cleaner data here.
I have hit balls off an outside mat that is wet but is a thick pile. The clubface gets wet in thus case and you get a flier that spins less and more distance. So, a little water that causes less friction in your case is not wet enough to cause this same flier lie. Thanks, very interesting
Anyone have a good source for high-quality mats? I got a fairly expensive and highly rated mat from Amazon, and it just isn't anywhere near the quality my local courses/fitters have.
Please be careful when trying this on a camera based launch monitor that sits to the side.The water droplets that spray out on impact may get into the machine and short the electronics.May I suggest a little dry silicone lubricant on the mat or sole of the club instead.
Why not try a deep pile rug or mat? Would that simulate actual turf? This way the ball strike would be centered on the club face and the spin of the ball could potentially be the same as a fairway, rough, etc.
I believe he has a video out there from a recent attempt at qualifying on the Sr. PGA Tour…don’t think he made it…but a great video of the pressures in the qualifying and how differently things go from a studio! Matt’s a great guy putting it all out there!
You guys got the part about hitting it high on the face wrong. Mats will DEFINITELY promote you hitting it high on the face, not low. Mr Short Game is just too good of a golfer to hit it high enough on the face. I know this because when I started golfing, i set up a mat and a net, and used impact tape to determine where I was making contact. Heavily tended to hit high on the face, hitting about 3-4 inches behind the ball sometimes - because you can get away with that on the may. I had to work on low point control, as do most novice golfers
Really fascinating info regarding the increased spin with the hitting surface wet. I just wonder what results you would discover if Mr Shortgame.were also all wet. Keep up the good work, and by all means take all or part of your investigative efforts outside. Maybe you can catch a shower.
Wouldn’t a wet club face have similar results? You should test this using a dry mat and only spray the club face. Dry the ball between shots. Also use a small/short tee with and without the wet club face to see results.
the ball being shoved into the turf is exactly what is happening. I have noticed that myself creating spin on mat is hard to do unless you scoop the ball. People who complain about their strike point being high on the face on a mat are fatting the ball and have poor low point control relative to timing of the release. The club will visually dig into (depending on turf) from just behind the ball and up through it. Should water be used to help with fitting, maybe. You guys should absolutely test spin out doors after a fitting using the water
When I hit high on the face off of the Sim turf in my irons, I have hit the shot fat. And of course, a fat shot on that turf totally slows the ball speed and the other numbers. Hitting fat is not a fun miss. Haha
the only problem with the water theory is technically the ball doesn’t interact with the ground when it launches, ie., you aren’t pinching the ball against the turf when you hit it…it flies directly off the clubface into the air…the pinching was a popular theory years ago, but modern high speed cameras show that isn’t the case at all…which then begs the question how does the wet turf theory work then???????
This is exactly why I watch the channel. You guys make a good team ... more collaboration, please.
i would love to see a part two where you go out to the range and check the numbers out there to compare. thanks, that was a great video!!
Part 2 will be done!
It would seem that adding a very short tee into the test would have been insightful to this test also. Having affectively eliminated the mat friction.
"I'm a yard closer" must be one of the greatest observations in the history of simulator golf!
two legends in the youtube golf game. thank you both for all of your content!!
Brilliant! Love it! Two of our faves together. Great camaraderie and synergy. Thank you, well done, and congrats !
Thanks so much!

Lots of ideas for a part 2 of this video.
Definitely need to do a part two outside using the same balls. This will highlight the differences.
THAT WAS AMAZING!!!
You just revolutionized club fitting indoors forever! B
Just as well I live in Scotland where the horizontal wind pushes the rain into the bays - extra spin!!
You’ve just invalidated every club fitting that achieved “optimal spin”.
Indeed. And see 1996 PGA Championship winner Mark Brooks on the following video at the 2nd Swing Golf channel: OLD vs NEW Golf Irons Testing with Mark Brooks
@@mtmmason exactly what I was thinking.
If it's a good fitter, they should know the spin difference and explain that to the golfer.
Different mats are made of different material too
Great vid guys! But aren't different mats made of different material where one may be sticky and another may be slicker?. Just sayin'
wow, this is incredible data. Always wondered why I was low spin indoors, and outdoors I have plenty, or even too much at times.
Brilliant.... excellent video with surprising results..I must take a spray now to the range.....
Great content! I'm an outdoor player most of the time, but go to indoor launch monitors to "check my numbers". This seems super useful.

It will happen. Mat spin 2.0 is on the schedule.
Fascinating result from your tests. The water in the mat must be simulating the natural state of water in grass on the driving range or golf course.
Very interesting, should be interesting see same test at the range… anyway it raise some questions then on the effectiveness of fitting done on a mat…
High contact on the face off of a mat are usually fat shots
The general consensus on google is that mats cause higher impact in the face and higher launch/lower spin. Makes me wonder if it takes more impact tape type comparisons.
I use real sod in the hitting area in my indoor sim. I just replace each time!

After watching all of this one, now I want to go ho test my FiberBuilt, lol
I had 9700 on my DIY 9 iron chipper yesterday
I wonder what the grass series does wet?
I have also heard that the dust from the mat and the Club face can cause the wall to not spend as much inside
You nailed it when you said people don’t want to hit down on mats and wreck a shaft.

Might have to test this myself next time I'm in my sim
How about with fairway woods? I assume smaller differences but is there still a difference?
Smartest video out there…curious if descent angle also is skewed lower than actual 😮
Just looked back at the data and all the descent angles were the same with the exception of the steeper AoA balls that had lower launch angles.
I’ll have to try this in my home sim.
Definitely need to get high speed video on each turf to see what might be going on.
This makes total sense. I believe in this theory.
So now should we come up with a patent mat that gives accurate spin vs normal outdoor turf
That explains the theory that on wet courses, the ball goes higher and spins more. Also shorter here on the PNW coast by a club or more.
That was some fine ball striking! Wow!!
Wet ball is essentially a flyer lie and you get less spin, but, yes, higher launch. It should make most of your clubs longer, not shorter-but long irons might get shorter due to a lack of spin.
Thanks!
We cooler temps and a lot of humidity ball doesn’t travel as far.
Inland in Cali or the desert - Wow!
@@johnbrodnik839 it’s probably almost all due temps assuming altitude is the same. I think rule-of-thumb is about 2 extra/less yards for each 10 degrees above/below 70 degrees-so like nearly a club if your play in 100 degree desert versus 60 degree PNW.

Would have been great to get a baseline outside to compare off the grass to off the mat
What would happen at flat angle of attack
This deserves to go viral. Very useful information. Like and comment please.
I’d like to see the comparison to when he hits off grass
Makes absolute sense. That's why when we practice on mats and get there on the course things are somewhat different. And there are so many kinds of turf. Go figure.
Nice Video
How would these numbers compare to hitting off of real turf.....wet and dry?
Going to do a follow up with real grass numbers.
It's your fault now if someone shows up in my fitting studio with a spray bottle... LOL!
You need the Uneekor to see the club interaction
You need to do this at a range with real grass right beside range mat, that'd be good comparison
This info is going to make indoor public ranges make a new “no spray bottle zone” and makers of curtains on overdrive, keeping up with spotted curtains syndrome 😅

A full 8iron shot that has 8000 spin but it’s going up to 50 feet isn’t going to stop on a green. As long as the 8iron has enough descent angle, 6000 spin should be fine, as descent angle is doing most of the stopping on full iron shots.
Wow custom fitters take note. Wet your Matt to get more realistic numbers. Brilliant.

Next time I’m at the range, I’m bringing a mister machine with me…LOL….😂
Id like to see it done out on real grass now and see where the spin numbers are
I have hit balls off an outside mat that is wet but is a thick pile. The clubface gets wet in thus case and you get a flier that spins less and more distance. So, a little water that causes less friction in your case is not wet enough to cause this same flier lie.
Thanks, very interesting
Anyone have a good source for high-quality mats? I got a fairly expensive and highly rated mat from Amazon, and it just isn't anywhere near the quality my local courses/fitters have.
I was confused when you started spraying the turf. I thought you said “WET MATT”
Please be careful when trying this on a camera based launch monitor that sits to the side.The water droplets that spray out on impact may get into the machine and short the electronics.May I suggest a little dry silicone lubricant on the mat or sole of the club instead.

I was waiting to see Mr Short game with a tee in his mouth for the intro as you said hitting off a Matt
Let's face it. Matt belongs on the PGA Tour or I guess at his age the senior tour (whatever it's called now). He's a machine!
I believe he has a video out there from a recent attempt at qualifying on the Sr. PGA Tour…don’t think he made it…but a great video of the pressures in the qualifying and how differently things go from a studio! Matt’s a great guy putting it all out there!

Club fitters should have a wet zone Or I need to invent a hitting mat that has a slick surface so the ball doesn’t get the spin slowed down
Wish you guys would have gotten some numbers from a Fairway so you had a base number😊
Will be doing a followup video.
Wouldn’t a wet club face have similar results? You should test this using a dry mat and only spray the club face. Dry the ball between shots. Also use a small/short tee with and without the wet club face to see results.
This came from a video I did where we tested the ball being wet vs dry and started getting these odd high spin numbers off the wet ball
Thought you were doing an inside test and then outside to compare.... don't understand the point of this test without doing that.
the ball being shoved into the turf is exactly what is happening. I have noticed that myself creating spin on mat is hard to do unless you scoop the ball. People who complain about their strike point being high on the face on a mat are fatting the ball and have poor low point control relative to timing of the release.

We are going to do part 2
Hard to believe they didn’t plan to take the very portable launch monitor out to the range when they were planning this video.
Swing and a miss.
When I hit high on the face off of the Sim turf in my irons, I have hit the shot fat. And of course, a fat shot on that turf totally slows the ball speed and the other numbers.
Hitting fat is not a fun miss. Haha
the only problem with the water theory is technically the ball doesn’t interact with the ground when it launches, ie., you aren’t pinching the ball against the turf when you hit it…it flies directly off the clubface into the air…the pinching was a popular theory years ago, but modern high speed cameras show that isn’t the case at all…which then begs the question how does the wet turf theory work then???????
I would have liked to see another data point, hitting on real grass.
35* 7k but a seven iron is rarely 35 any more so 6k at 31 like a modern iron is actually really good . Height and land angle master too.
