Huge ballflight Problem Mevo Plus

[Daniel84]

Hi guys,

really need your help - I am completely lost. Trying around for 5 days now and don't get it...

Have built a huge indoor simulator for my Mevo Plus.
Got over 4 meters of ballflight - and no restriction from ball to mevo in any way.

Hitting Box is almost 4 Meters wide and 3 Meters tall.

Easy wedges are registered great - all balls landing in a nice group - trajectory, everything fine.
Easy 7 irons are ok as well - but they are starting to get a strange draw behavior at the end of the ball flight.

The further I get up in my numbers the stranger it gets. Guess depending on launch angle and ball speed.

Everything goes low as hell - launch angle and height are so off, don't even know what to say.

I am swinging smooth Drives, to make sure i got good contacts.

Swinging up at at least 5 degrees on the ball - and it starts with 8° launch angle and has 45 feet in height...
And all balls get extreme draws - I would even call them snap hook.

I am a former Playing Professional - so I am not a total noob and I have a feeling how I hit my shots and how they should fly

I tried absolutely everything - thought the strange draw might be an alignment issue - moved the mevo from right to left to just try of anything changes - nothing...

Had it sit on the floor at 7 - 8 - 9 feet and tee surface height at 3cm - same behaviour

Elevated it on a stand with 3cm and set surface height to 0 - same behaviour

Filled up the gap between the elevated stand and the tee area (as described in the manual) - same sh....

I am really depressed right now - was looking forward so much to be able to finally do some training during winter here in Germany - and it just won't work

Try putting a mat down between the Mevo and your hitting mat so it is a completely flat surface. The Mevo does not like having a “valley” in between it and the ball. I had similar issues and once I got rid of the height differences, number were better. Hope this helps.

sorry missed the part where you said you filled the gap. I would try Flightscope support. They are good to work with.

Have you run the Flightscope interference app? All the metal might be the culprit.

[aussiebenny]

Is that bar below the screen a sheet of metal?
If so, that would most likely be the issue as metal causes a lot of radar bounce back.
So the signals from the low trajectory shots would see a lot of interference.

[Daniel84]

Hey guys - seems I've built the worst possible hitting box for a radar system.

Sidewalls are aluminium sheetmetal - behind the screen there are sandwich panels from the outer wall - and a steel beam.

Guess I have so much metal stuff around - I can be happy that it even picks up a chipshot

This post is incorrect. The mevo+ is a Doppler radar and detects changes in movement. If the metal isn’t moving the radar doesn’t see it. This is why the mevo hates fans. I playing in a metal shed and it works perfectly and this has also been confirmed by flightscope

How do you check interface

[Håkan]

Hi, It looks like you have it in "Indoor mode". Try Short indoor mode instead.

Firstly do you get that behaviour in fs golf?
there is an issue in the way spin axis is produced from flightscope devices and it is not compatible with most golf simulators which is why you have a better experience on fs golf. What has been found lately is that the mevo produces an offline value, which is how far offline the shot landing will be from centre. Simulators need to use this number and reverse engineer the spin axis for their game to produce the correct ball flight for a fs device.

secondly. Mevo+ really struggles with low launch angles. At around 8 deg and lower it appears the device gets confused between the club and ball. If you can launch your driver 12 deg or higher your should have a better experience.

Short update on my case.

Reached out to the support yesterday, after 3 weeks have passed and they didn't get back to me after sending in my data.

Short answer: "Everything seems fine"

So basically they did not even check the data - absolutely no chance that there is no interference in my setup - absolutely everything behind the screen and around it is metal...

When asking them - why the data is so completely different to my outdoor readings, if everything is "fine" - they don't even response to that...

Outdoor Driver is launching at 14° - ballflight is straight / slightly push right as standard - Ballspeed around 155
Indoor mevo measures 7-8° launching pull duckhooks that all land within a circle of 5 Meters at the 175 Meter mark...
I seem to be them most accurate indoor pull duckhook player in the world

Spinrates are calculated 9 / 10 shots - and even when it picks one up it shows 4000 Spin with my 7 Iron...


But as the support says - everything is working fine

How much ball flight indoors?

I wonder if you are the perfect candidate for the wire mesh upgrade to help with the radar reflection. Flightscope mentioned this in one of their webinars. They were having issues with the radar seeing a battery station on the other side of a wall. I would definitely ask what they used though.

Something like this.

Problem is - I would need like 300 square meters of that stuff to cover all around.
My setup is in an alluminium sandwich panel hall - and event the hitting box itself is made from alluminium sheet metal...
It is just covered with foam - but the radar penetrates the fom and gets also reflected by that

I know my setup is trash for a radar - just wondering that the flightscope service wants to tell me "all fine"

[preludesam]

I think your math is slightly off. 300 square meters is 3229.17 square feet. That's the floor size of a large home. You would probably only need a roll of the stuff I linked or maybe a roll and a half. You only need to cover the enclosure and the screen and it definitely needs to be on the inside of whatever metal you are trying prevent reflections from.

[grant2145]

Have you tried covering the metal areas in the radar’s field of view with the material you have on the left side? Something that will absorb the radar waves instead of reflecting them. The flightscope interference app can detect outside interference from things like electric motors but I’m not sure it detects reflective interference. The radar could be reflecting off the sheet metal right back to the mevo causing issues. Outdoors the waves only bounce back from the ball and club.

My first thought on this was to say "cut your losses by selling the Mevo+ and buy a camera based system" after seeing all that metal! After thinking about it a minute it seems there are a few things you could still do to try and troubleshoot your problem to see if you can circumvent it. In the replies above I did not read anything asking where your projector is located. If it is located in-between the Mevo+ and the screen it can be causing you issues. The projector has a fan on it. I wrapped my projector with aluminum window screen. Another you can try is to remove your hitting area (since you said it also has aluminum) and place just a piece of carpet or something there to see if that helps. I assume you currently hit your driver off of a tee so it shouldn't be a problem to try this test, right? Another thing you can try is to just get a 4' x 4' 1/8" particle board (or equivalent in metric!) and wrap it with aluminum window screen (pretty cheap and easy to do.) Then you can place directly behind your screen or else where to see if you can narrow down where the problem reflections might be occurring. I am sure you could think of a few other ways you can rather quickly figure out if you can make it work with the radar based Mevo+.

BTW. I can see how Flightscope could say "no problem seen in interference app" if that data is only looking for interference in the way of motion! All of you aluminum reflecting surfaces are not moving! Right? Yet conflicting reflections during a hit/read of ball and club could give it a problem.

Anyway, hopefully this gives you a few things to try and decide what to do next!
Good luck. I can also say that aluminum screen has definitely solved issues I had with both the projector, and also a heat pump unit fan located outside a wall directly behind my screen.

How do I find the Interference app?
