28.3 degree launch and misreads and how it was solved.

[Brutaly]

Hi.

The last two weeks i had two issues:
28.3 degree launch on the driver
Increased number of misread

I double checked my setup and i could not find a single thing that was wrong. I was sitting in my couch and suddenly i got a revalition.

I actually had a client over for a fitting and based on what i knew about him i had moved my clubs around so the setup that he most likely would enjoy the most was moved to the right side of the room and placed leaning at the wall instead of hanging on the wall.

I went out and rearranged the clubs so it was similar to before his visit and suddenly the 28.3 was totally gone. The clubs disturbs the radar.

In FS defense i have like 40 clubs in there with mostly steel shafts and approx 15 different fw/drivers.

Regarding the no reads it also struck me that i have started to move the ball to the right of the alignment line and my gut told me that the increase of misreads started after i did that move.
Said and done i moved the ball the the left of the alignment line and no more misreads.

I also found that putting in E6 is much better if the ball is placed to the left of the alignment line.

Above for a righty ofc.

Interesting. I’m getting high or default 28.3 VLA with driver ever since I received my Mevo+ months ago. I have no clubs in the way. No metal. No walls on the side. Been struggling with this.

[trumb1mj]

I had this issue and came down to setup. Try lining up the line left of the center of your net by 6" or so.

[pwade3]

Does that not effect the HLA then?

[trumb1mj]

For my unit, 6" left is centered.

[Shankz]

I am in the same boat as far as the 28.3 launch angle with my longer clubs ( driver, 3 wood, 3 hybrid etc. ) I talked with fightscope and they said try raising the mevo+ up 1/2” to 3/4” above the ball. I did this and it seemed to stop for a short time but it’s back. I would say that I get about 6 to 8 of them when playing a round on E-6. Funny thing they always seem to happen on shots that feel and sound really good. I seem to get a read with no info displayed other than a 0.0 spin axis when I am in the flightscope app. Here is a picture of my set up. The t.v. Is 7 feet to the right of my hitting area and the fence is a foot behind the mevo+. The mevo+ sits on some pavers so that it is level with my hitting mat with a distance of 8 feet to tee and 10 feet to net. I line the mevo+ up with my putting strip. My clubs during play are kept back by the fence in the corner opposite the mevo+ during play. The only other metal are the latches and hinges on the gates of the pvc fence that is over 30 feet away from the mevo+. Oh and the metal cable and clips holding up the net. I can’t see any of this being an issue but if anyone sees something that I am missing please feel free to let me know. At this point I am out of ideas.

[pwade3]

I’m not seeing any pictures.

[tinker812]

someone mentioned on another thread that the flight data are more reliable when the space between the mevo+ and the ball is at the same level as mevo+ as well (rather than raised mevo+, then lower floor in the gap, then raised hitting mat). no first hand experience yet tho...

[Shankz]

[Brutaly]

I would move the bag so it is beside the radar and also try to move the plasma screen. Plasma screens have a lot of radiation etc that can interfere.

But i think the most important part is actually the fence behind the radar. When i was in the military service we learned that all radars also has a side- and backlobe. I believe that pulse doppler flat arrays also have that. Try to have the mevo on the opening of the gate.

Side note, i hope you realize that it is only a matter of time before you hit your self or your neighbors!

[Shankz]

I do keep the bag by the fence. The net is 15 feet wide and 91/2 feet tall so I think the neighborhood is safe😜. It’s an led tv not a plasma but I don’t know if that makes a difference as far as interference. But honestly if the tv and fence are an issue then I have some serious doubts about the design and marketing by flightscope. I will have to keep trying different distance setups to see if anything changes. Thanks for your input.

[Brutaly]

So you are one of those lucky ones that never shank the ball. You are like unicorns to me 😉

Is the net behind the beams? It looks like that on the picture.

[The19thHole]

15' seems pretty wide to be safe. I have a temporary set up at home right now while I wait for my Mevo + to come in and it is only 7' wide..Haven't missed it yet in a couple thousand shots. (my son on the other hand seems needs a full enclosure and he still found a way to miss, but he is 7).

*Though I did just notice that your user name is Shankz so thats pretty funny.

[Gresh12]

Given Flightscope seems to be able to remote in and look for interference I think they should add that to the app for device setup. Not to diagnose exactly what the problem is (I’d guess pinpointing would be tough) and I’m no radar specialist but if they can detect interference I’d think they could program a mode you place your device in its environment with no ball (to avoid the dot) and it returns a pass or fail indicator. Pass meaning it sees nothing right now And fail means it’s picking something up that may confuse it during use. Presumably with no person, club or ball anything else is just noise and a potential problem. This would allow people to test environments and move things to see what eliminates the noise and likely reduce tech calls to Flightscope.

They have marketed this as a sim device at consumer level which means a lot of people are going to be trying to fit it in to tight spaces so any early warnings that you may need to reconfigure would be useful.

[Brutaly]

Great idea.

[Shankz]

Perhaps I should restate then, nowhere can I find any warnings about having to worry about what’s behind the unit. If anyone can point out where that is I would love to see it. I am overall very happy with my mevo+, it just has some issues that need to be worked out.

[tonybrown32]

Gresh12 I've had the same issues as you.. I have to say the .09 beta improved my right spin axis issues significantly. Driver toe shots still don't hook or draw much, if at all, but at least those toe shots stay pretty straight now, and even at times do draw a smidge, rather than the consistent exaggerated right spin axis I got before on toe shots which was just wrong..

I don't think i've ever had Mevo+ show me a draw shape off a toe shot prior to the beta... and i had to really WORK to get a draw shape on shots that started right of center before the beta... post beta, I've hit several push draws now without even trying.. which is great.. is it perfect? no.. but much improved, and I now trust what my Mevo+ is giving me on off center hits, and is more like what I see on course.. I didn't trust it before unless it was well struck shot, so improvement was huge for me at least.. but I think each environment/situation will vary too..

[pwade3]

tonybrown32 Uh oh..... I’m starting to think its me. Lol 🥺.

[tonybrown32]

pwade3 finally getting on the course to see my shots has also been beneficial to see how Mevo+ correlates with what I see on course for sure... the more I have been playing this last week or 2, the less I think the Mevo+ is lying to me.. lol. Not to say those spin issues didnt exist though, same as yours.. they were most definately there.. and I'm not convinced they are 100% resolved with the Beta.. but definate improvement.. although I saw big improvements with getting Mevo on a level surface with no gaps between Mevo and ball too, so I think it was a combination of things that together made a difference...

[pwade3]

I was asked by FS to try a particular setup and hit using the FS app. They wanted 8’to tee. Minimum of 8’ of flight. Too have sensor on the same level as tee without any disruptions in elevation between sensor and tee either up or down.
I took my 12ft x 11ft mat and turned it around (so my stance is on original hitting strip)and moved it further back so that the Mevo+ could sit on it and have the exact same surface to the tee area. I used the E6 driving range at 12 deg tilt as E6 was where I was having the biggest issue. I had what I would say was very good readings of VLA. The highest I had was 16 deg and that seemed slight high for me. I hit 22 shots and VLA was around averaged around the 12 deg reading which is normal for me.
I have never been able to produce that consistency before. I tried low shots and tried high shots (which I’m not very good at) and thought it was excellent.
I will try the FS app tomorrow at the 18 deg tilt that they want.
I have tried a lot of different setups including making a surface that is level to the tee, but they were only less then a two feet wide. It seems mine is very sensitive to any drop offs from sensor to tee which is disappointing. I have to spend more money purchasing more turf to add to what I have to create a solid surface was very unexpected.
In the FS app under manual for Mevo+ that you download it shows the sensor on the same level as tee, but shows a drop off between them. Seems odd.

[trumb1mj]

This is disappointing. I have the drop off scenario which has to be extremely common... I have my mevo+ up on a platform to bring it up to the same height as my mat platform.

[pwade3]

I agree. This is disappointing. I am going to bring this discussion up with them. I had the same setup as you with the sensor sitting on a spare piece of turf I had so it is on the exact same height as the tee surface, but with a 1” drop off between the two. There instructions show it as ok, and why have a setting in the setup to be that way if it will not function that way. A lot of people will be setting it up in there garage that way so this will be an issue unless its just a few sensors that have an issue. So now I have to spend an extra $1000 for another section of turf.

[tonybrown32]

I've also seen much better results, especially with launch angles, having Mevo+ on the same level as my hitting surface without any gaps between... in my experience from best to worst:

Mevo+ on same level with no gaps = best results
Mevo+ 1-2" below the hitting surface, adjusting tee height in app = ok results
Mevo+ at same level as hitting surface, but with a gap between = worst results

I'm only speculating here, but wondering if having a hard/solid/smooth surface in that gap between Mevo+ and hitting mat makes a difference? In my case, I see noticeable difference when Mevo+ is on the floor of my gagage, but there is hard/smooth concrete between Mevo+ and my matt.. vs say an indoor facility they may have at FS headquarters, where there is turf on the ground, and the hitting mat is placed over softer surface or turf... I don't know enough about Radar reflections however to know if they may or may not reflect more off oa solid surface like concrete between Mevo and ball, vs say turf on the floor... it could explain why some see issues with the gaps/surface height more than others... if it's more the reflections off solid surface vs turf.... just a thought.

[Wormburner]

From my experience having a level surface from M+ to the screen fixed all issues. In beginning I had a gap between M+ to ball and between hitting mat to net. I did not have terrible misreads on clubs but it did misread more often. Putting never worked with the gaps. I am now transitioning to my SIM build which has turf throughout room and it seems to read nicely. I have not played a full round since moving to Sim room so not a whole lot of data yet. I may be complaining on here in a few days!

[pwade3]

Flightscope is telling me that having it 1” below or level with the tee surface is fine, including gaps. I have not had success with either of those setups so not sure what to think at the moment. I have let FS know of what I experienced and see what they come up with. Look forward to Wormburner experience with his new sim room.

[tonybrown32]

I just watched the webinar on Home Simulator Overview the other day, and has a lot of good info... scroll to the bottom via the link here, it's the most recent webinar from June 16th:

https://flightscope.com/webinars/

[pwade3]

tonybrown32. I watched most of it. Has good info in it but should have been put out a long time ago. I noticed that he said about raising the M+ to be level with the tee, quote “we would discourage that” yet their manual that you download from the FS app in the help section requests that it is raised as per photo in post #10. Someone should asked them to correct that for the sake of clarity. I don’t want to see people setup wrong and get issues. Since I no longer have one its probably not right for me to do it.

[tonybrown32]

pwade3 agreed 100%. The webinar totally confirmed my experience though.... for me, raised on 2" of foam with a gap was worst... on the floor using the tee height adjustment settings in app was better, and fully level surface between mevo+ and ball was best..

It's unfortunate the setup diagrams provided with the Mevo+ that came with my unit, explained to set up your Mevo+ level with the hitting surface, and illustrated a gap between Mevo and hitting mat... I assume they've learned since then that it can cause issues.

[Wormburner]

I hate you are having these issues. Do they plan on sending you a new M+?

[pwade3]

No. They have been very good working with me and confident the issues will get fixed. Just a confusing issue. No sure they have one to send me. Lol. 😂

[mmkat99]

Have you gotten this spin issue resolved while working with them? I’m going through the same issue in my garage. Most all my shots are straight. No real curve whatsoever. I was told my spin is off when I sent in data and they said they’re seeing interference. I sent them a photo of my setup which is in my garage with a machinery off to the side. Nothing is in the direct path. They thought it was fluorescent lighting but all of mine is LED. They then had me use aluminum screen over my electrical panel. No change. I put some over my lights on the ceiling. No change. I’m beyond frustrated.

[Dax]

Could it be your garage door? Is it metal?

[mmkat99]

I have two garage doors, both are metal. I have to hit towards one of them so I’m choosing the smaller party door. It’s 3’ right behind my net. How do you overcome that huge door? It’s 9’x7’ approx

[Dax]

You could try the mesh screen that has been suggested and mentioned in the forum. Last time I recall reading about it was someone using it for their projector. FS was quoted as suggesting it as well early on and so you could try contacting them. I would mention your door to the tech you spoke with to get their thoughts.
