Mevo+ spin rate. Is it E6 or the unit?

[Harkerad]

If you have noticed bad Spin Rates for your shots are they occurring in the basic FS apps or in E6 or other Sim software? GungHogolf has indicated that E6 might be adjusting Spin rates if the rate is abnormal for the club selected. Make sure to select the correct club in any of the software and report if your numbers are off.

When I was demoing E6. Spin rates on greens were insane. I was getting huge suck back on wedge shots. I would lean towards E6 being the culprit.

[Gresh12]

I'm still doing some testing in my indoor setup but I had a bunch of questionable spin ratings last night. Comments:

- I am setup at 8'/8' as that is all I have and all shots I had a dot on the ball
- I hit in to a net that currently has a white towel hanging down as a target (I used it when I didn't trust SkyTrak HLA) so I don't know if the ball reads oddly when it hits the towel and kicks it up before they both hit the net (I will take down the towel tonight as I am totally confident in the HLA on Mevo+)
- I haven't tried E6 but I played 9 holes on TGC last night and had some spin challenges
- I had the "high spin correction" setting turned on which was maybe a mistake but I'm fairly certain club selection will drop the spin if it seems to high. I had to layup with a 9 iron after a bad drive and forgot to change the club setting so it was set on 3 wood and I got a spin number of about 1800
- I did this another couple times off the tee when I hit 5 iron but forgot to change it from driver (I have low ceilings so can't hit my long clubs indoors)
- my mat is 1.6" higher than my Mevo+ and the tee surface setting is in full inches so I had picked 2" as I rounded but I'm wondering if choosing 1" would be better or miniscule differences won't have an impact
- I did have a number of very low spinners for me mixed in with what I would have expected (i.e., decently struck 9 irons spinning at 4k when I'm normally 8-9k)
- I then hit some balls in the FS app and the crazy spin correction shots didn't exist (i.e., no <2k spin on short irons) and the number of relatively low spin ones reduced but I still had some 7 irons spin at 4k which is low for me (they were a little heavy which would usually drop spin on SkyTrak to 5-6k but not close to 4k)
- While I didn't have any other comparator (my SkyTrak shipped out before the Mevo+ arrived) none of the shots felt like they curved the wrong way. Some of the low total spin ones curved a lot more than I felt they should but I think that may be a function of the low backspin not stabilizing the flight in the model (i.e., a long iron curves more than a wedge)

A bit off topic but my thoughts after a couple days:

- I have total confidence in all measurements except spin (which I think isn't a shocking outcome)
- I believe the FS ball flight algorithm is more realistic. On a lot of shots I get similar measured data as to what I got on SkyTrak but I'm now getting flights that seem closer to what I see on the golf course. The SkyTrak over exaggerated curve in my opinion and I got a lot of carry out of SkyTrak on irons that I wouldn't generally get on the course
- I get a decent number of obvious misreads on spin from Mevo+. The good news is they are very easy to identify and remove from practice sessions but for simulation in a tournament I'd be weary (I hit a 9 iron about 180 yards carry then another 20 roll after it flew the green)
- I have a non-permanent setup and the camera alignment is infinitely better than chipping balls fiddling with Skytrak trying to get a straight one to read straight (partly because I felt SkyTrak wasn't great on HLA even when aligned properly
- For my purposes I have zero regrets in making the switch but if I was a tournament sim golfer that really cared about my score I would give Mevo+ a bit more time to see if the spin readings can be solved by setup/software (I acknowledge radar indoors will always have some challenges but I also believe no launch monitor is perfect)

Gresh12 after my few evenings with the Mevo+ (arrived Monday), our experiences are quite similar.
- I'm 9' ball to screen and 8' ball to Mevo+
- The first day, I mainly hit 7i on the FS Golf app, and total spin and HLA (the metrics I'm most interested in) seemed very good, and much more consistent than my Skytrak, however spin axis seemed exaggerated to the right. I play a draw, and have a very difficult time creating one on the Mevo+. I have to hit what I feel like is a 20yd hook to get a slight 2-3 degree left spin axis
- Unfortunately I sold my Skytrak as well, and have no tools to compare Mevo+ numbers

- Day 2 I played with driver on the FS Golf and E6 app and noticed some wild HLA and right spin axis numbers... very concerning numbers in E6 first, then again in FS Golf as well
- I also hit 8i on E6 range and noticed many sub 2000 spin results.. which I thought was very strange, and it occurred often
- After some advice to select the club being used in E6, and to validate my alignment with the boresight camera, I solved some issues
- #1 be SURE to select the club being used when playing in E6. It matters. I was hitting 8i but unknowingly had driver selected in E6, and had many total spin results under 2500rpm which is very wrong/unlikely. Once I selected 8i, that issue was completely resolved.. nothing under 4300rpm or so over many shots
- #2 be SURE to set the alignment line using the boresight camera in FS Golf to align to BOTH the ball and through the target or impact point on your net/screen. I had mine errenously aligned through the ball, but about 12-18" away from the impact point of my screen... it caused wild HLA numbers. Once aligned.. HLA has been great.. no issues.

Summary of my findings in limited use:
- Alignment is extremely important
- Selecting the correct club in E6 (and I assume FS Golf or other apps) is also important, more so when switching between wedges, irons, and woods than say between 8i and 7i.
- Spin axis seems to be right biased. My push draws don't generally show any right spin axis at all.. but I am indoors, and cannot see my actual ball flight and do not have another device to confirm my feelings on this. Purely based on feel and how well I know my shot shapes by feel.
- Exaggerated right spin axis increases as club loft decreases (ie much worse with woods than irons). This could very likely be the shortcomings of radar based units indoors struggling to effectively identify and adjust for gear effect. This is a known shortcoming with radar indoors.
- Other metrics all seem very accurate, very consistent and on par with what I would expect based on my experiences with other units at fittings and lessons (X3/GCQuad). Right spin axis bias is my only concern at the moment.
- The spin axis could cause some people issues if their main use is to play simulated golf and/or play tournaments. Personally, that is not my use case for the Mevo+. I use for practice and distances, and the occasional mess around on the 5 courses that come with Mevo+. I just keep in mind that a 5yd fade is ok, it's probably a straight ball or slight draw... and at least the Mevo+ reads this way consistently unlike my Skytrak that would be far more random in shot shape, and far more exaggerated in the left side spin an deviation. I just need to aim more left to account for the right side spin when playing courses on E6... it does take me out of my normal game though, so I can see this being frustrating for those wanting to use the Mevo+ for tournament play .

I never suggested E6 Connect is adjusting spin rates - I know for a fact it doesn’t.

[flightscoperick]

E6 Connect uses whatever perimeters your launch monitor sends it. It does not change any off it.

Wow, you're hitting at 9' ball to screen and 8' ball to Mevo+? Does Mevo+ have any way to manually adjust (calibrate) that spin axis bias?

You've just convinced me that Mevo+ is not something I want to use for indoors simulation. It may be great outdoors, but I don't want to practice/play almost 6 months of the year on a launch monitor with that much spin axis difference from a real life shot.

I will look at the Optical readers (Uneekor mainly), and/or sticking with the ProTee that I have. I cannot give up that much spin differential when practicing.

Thanks for the honest post.

Not sure I would write it off yet... remember, its 3 days with the unit, and initial impressions and I havent hit a ball outdoors all winter to confirm my suspicions are indeed accurate.. time will tell as more users get their devices.

[Gresh12]

I agree I wouldn’t write off yet but radar and spin axis in doors is a challenge. Outdoors in my one session it was bang on every shot which my SkyTrak never was (but I had challenges with the handful of times I took SkyTrak outdoors in general)

[Harkerad]

Those that are seeing Spin rates that are off, take into account the following and let us know your thoughts.

Thanks for the input. Here was the response I got from FS support:

You are correct in assuming that longer ball flight will usually result in more accurate readings, but when comparing short indoor to standard indoor, another important consideration is the amount of time the ball is seen by the radar. You will still get accurate readings based on ball speed and launch angle, however as your ball speeds increase with the club you are hitting, the radar has less time to see the ball's rotation to calculate the spin, which can have an affect on carry distance.

For example, if someone has a driver club speed of 100mph, and a ball speed of 147mph, their calculated carry distance may be a little more consistently accurate than a golfer's driver shot with a club speed of 125mph and a ball speed of 187mph. That is only because the launch monitor has the ability to collect just a little bit more spin data from the slower shot. Whether you are in short or standard indoor mode, as long as the ball is seen clearly and accurate spin data can be collected, both modes can be equally accurate. There are just some circumstances that make it difficult for the launch monitor to collect the data it needs to display accurate information about the shot.

[Bubba22]

I still question the need for club selection for correct direct spin measurement. I have no issues with needing to select a club but there must be some calculation involved if that is the case. For the most part calculated data is extremely good. Perhaps Flightscope can come on the forums and give us a good explanation of why one has to select a club for spin accuracy.

[tonybrown32]

It's not for spin accuracy in measurement.. but you need to select the club when changing between wedges, irons, and woods so the Mevo+ can monitor the appropriate launch window. The Mevo+ radar is smaller, and doesnt have a large radar window like their largest flagship units. If Mevo is set to driver, it's collecting ball data within a much lower radar window.. so if you hit 9I while driver is selected, the Mevo might miss half the flight of the ball once the ball leaves the low trajectory radar window, and it wont have a chance to collect as much ball data as it would had the 9I been selected, and the "iron" radar window used..

[games]

My understanding is club selection dictates a "shot window" where the radar expects to "read" the ball. IIRC, with smaller radars and batteries used in MEVO and M+, this is done for power conservation otherwise they would only last minutes. Larger radars like Trackman4 and X3 have very large windows, thus club selection isn't needed.

[Bubba22]

I get what you are saying. If the wrong club is selected then only spin is affected? I assume that all other measurements are ok? So you are saying that club selection will change the angle of the radar focus? Although it may not happen, it would be nice to have a Flightscope tech come on the forum. We have had a Trackman representative come on the forum in the past to clarify things with their products. I would encourage Flightscope to do the same.

[Harkerad]

Sorry Gungho I should have simply said that it makes a difference in the measured results.

Silence is a death knell up here for me. If someone from Flightscope cannot explain why their unit reads so incorrectly with spin with indoors, and short-indoors mode, then I take that as a statement that they do not care. Just saying....

[Brutaly]

My Mevo is not incorrect compared to my ST regarding spin axis. In other forums it has been reported that spin axis issues could be fixed with proper alignment which people seem to be sloppy with.
The only spin issue I seen is exaggerated driverspin.

[tonybrown32]

My Mevo+ spin axis issues weren't resolved with better alignment. I had some HLA inaccuracies and heavily fade biased spin axis. HLA was entirely resolved with better alignment, but I still feel my Mevo+ has issues with spin axis. It seems right spin axis biased to me, and never shows left spin on toe hits.. so certainly has difficulty with spin axis caused by gear effect.

[Brutaly]

It is known and communicated back in the day that FS don’t calculate/measure gear effect. They have never communicated that they will address it either.

[games]

FS is too busy fine tuning the M+ to waste time here. It's looking like history repeating itself with FlightScope's early improvements making M+ a game changer, just like they did with original MEVO.
