Where should Ceiling mount be placed

[GolferChris]

I have 9 foot ceilings. Where should ceiling mount ideally be placed in relation to ball position. (If I go too close to screen or too far in front of the ball hitting point. is there a risk of bounceback and the ball hitting the projector or a high/lob shot hitting the projector, or the club hitting the projector in the follow through ?
Appreciate anyy feedback

Ideally, you want it right over the ball. Or within 1-2 feet of that either closer to the screen or the opposite direction but still in line with the ball. That keeps it out of the way of your swing path.

There is some risk of a ball hitting the projector when bouncing back after a high lofted shot. My projector is about 6 feet from my screen and it takes the occasional hit (rare but happens). Fortunately the ball is not traveling very fast by that time. Still scares me anytime it happens. I think my issue is that all of my foam padding is near the middle of the screen where most shots are coming in. The top portion of my screen doesn't have much behind it so I tend to get a little more bounceback on wedges. I really do need to fix that.

If the projector goes too far back (in the direction away from the screen) you can begin to develop shadow issues.

Two things to consider:

1. Are you hitting from the center of the screen or off to the side slightly? If you are centered, then it's easy because you can put the projector centered over the ball. If you are hitting off-center, then the projector would not be centered to the screen if it were over the ball. Then you'd either have to get a projector with some horizontal offset capabilities or place the projector in the center and possibly put it in the way of your swing path on the follow through.

2. Make sure you get a projector with the proper throw ratio for your screen size and space. Once you know your screen size and the distance you'll be hitting from, you'll know the range of throw ratios you'll need to be looking for which will narrow down your selection a lot.

Great feedback. Thanks. Unfortunately I am going to be offset (only got a 10 foot wide space). so swing path is probably going to be an issue. Do you know if Horizontal offset typically takes much away from the overall image?. (I dont mind a little but dont want to sacrifice too much)

I can't fully speak on that because I've never had to use it. My hunch is that with the right projector, you will not sacrifice any image quality. Your selection may narrow slightly to find one that is capable of doing it (and doing it well with no image sacrifice) as I don't believe all projectors have that capability. How far off center do you expect to be? I know there are people here who do not have their projectors centered and they will be able to tell you more about doing that than I can. Since you'll be off-center, you might be able to mount a projector that is centered to the screen but well behind you (the opposite direction of the screen) that's just far away enough to miss your backswing/downswing. And because it would be to the side of you, you may not encounter any shadow issues.
