Need help with creating indoor golf simulator

[Dorba]

I have been using optishot in my garage without using golf balls. I purchased a Skytrak and a home series Net Return and started hitting balls in the garage. It is a 2 car garage which is 4' deeper than regular so I can set up and hit across the garage. I have a BENQ W1080 St overhead projector mounted on the ceiling which is 10' high. The wall I want to put an impact screen on is limited in width to no more than 8 ft wide due to circuit panel on left and media wiring panel on right. Height is pretty much open but after measuring the top of the picture is about 7.5' above floor. I was thinking about hanging the impact screen about 12" from the wall with a net behind the screen with a painters drop cloth (or something) about 3.5" from the wall that would be fairly firm. Sound isn't a big issue since I'm always listening to music. I would really appreciate any suggestion on materials and how do do this.The projector sits about 2' behind me (but I can move it).

Thanks for any help Don

If you want to figure out your screen size, and where you should mount your projector;

Thanks but I 'm not interested in buying a new projector I'm interested in info on the best way to construct a impact screen. I've read through so much of this but not all that sure how all these exactly fit my needs. Was hoping for some suggestions that would work in my situation. Pictures of the job would help and material that I would need would all be greatly appreciated

Sorry, that link wasn't for you to shop a new projector, you enter the projector you have in the projector calculator, and it will tell you how far away and how high you need to mount your projector to get a certain image size. If you already know what image size you are getting and know the proper height to mount it, then you are good already.
