GC2 New Build Confusion

[Dax]

Zmax, wrong terminology, I just tried to match the 70 mph swing described in the post above. I will try for the shot you describe, but not sure I can hit that shot with a 56 degree wedge and the tight lie from my mat. Never know though, will try it tonight.

I have my gc2 on order. While I wait I want to install ProTee 2.0 and GSX to interface with the GC2. Does anyone know if I will be able to download or do I have to order disks. Also if anyone has the links for GSX I would really appreciate.

You should have gotten an email with download instructions for everything. After install, you'll need to apply for all the licenses.

I have not recieved any emails with instructions, I placed the order on Thursday will they send me a disk or download instructions?

its all download. check spam folder

Guys, I need some more advice:
I'm fighting with an I-beam (8'10" above finished turf height) in my hitting space. I had originally designed and built for 14-17' from screen in case I went with a radar. When I decided on GC2 (and also noted that at 14' that many balls were going to hit the ceiling and not the screen), I realized I have to get closer to the screen. To avoid the i-beam, assuming a 1' gap between screen and wall, I'm looking at a screen to tee distance of 7-8' instead of the 9-10' I often read about.
So two questions:
1) is 7' too close to the screen? 8' ?
2) do i need a full 12" behind screen to the wall, or can I reduce to 6"? (planning on using a SwingSense double sided screen)

My alternatives aren't fun: Moving the wall and enormous shelving system that I built on the other side of the wall back 3 or 4' which also involves moving a structural post 2 feet, or getting fancy with the i-beam (i had it looked at and I COULD sister smaller beams on each side of the tall beam and cut out the offending section to buy back about 5" of additional height. I'd probably do the first option if I have to, but not excited about it

Answers to your questions:

1) 7 feet is too close, especially given that you have lots of space available. Most sims are about 10 - 11 feet from the screen. Remenber the closer to the screeen, the greater the likelihood of casting the players shadow on the projected image.

2) 12 inches behind the screen is the minimum distance. See the "Impact screen 101" forum for information. Highly recommended to back your impact screen up with a net to dissapate the impact of the golf ball and deflection of the screen.

I do understand that 7 feet is closer to the screen than what the screen people want you to be based on what I've read. However, as I run my 9th grade trig calcs I end up getting very concerned that I'm going to continually hit the ceiling with my wedges 52deg and up if I go back further than that. I really want to hit the screen and not the ceiling. I have a 10 foot ceiling. The projector I was going to buy was a short throw that with a 7' setback will fill a screen 14' wide and 8' high which should work very nicely in my 15' wide room. So I was going to have the tee right under the projector where my trig calcs say I will just barely hit the top of the screen with a 56deg lofted club.

Are my trig calcs wrong, or does everybody else keep their wedges in their bags on their sims or accept constant ceiling shots?

What do you think is the usual launch angle for a full shot using a 56 degree wedge? These type of shots are typically around a 40 degree launch angle. Are you intending to hit soft, high flop shots that have low ball speed but high launch angles? This type of shot can get to nearly 60 degrees but needs to be on a fluffy type of lie. Most golfers are not able to hit that very high flop shot off of a tight lie. This information might assist you with assessing the trigonometry of your potential set up. You also might be able to protect your projector with a box like shield.

If you plan on using this for sim play, you'll need to protect your ceiling. Flops, sand, and pitches will hit the ceiling.

I can't tell you what the angle is but I am 9' from the screen with a 10' high screen and I hit the ceiling well back of the screen with a 56 my 52 is very near the 10' mark when swung full..

Here are some interesting stats from Trackman data base concerning ball capture data from professional tour players.

Seems like you are leaning the shaft away from the target when you make contact with the ball and are adding a lot of loft to your full shots. You are losing a lot of potential distance since your 52 degree wedge is launching around 48 degrees.

Zmax has already advised you that you need to protect your ceiling. A few people have used carpeted OSB panels to protect the drywall.

Fhann- that is really great and interesting data, thanks for posting! I was really surprised by the launch angles.
I used to caddy at PGA tour Pro-Ams, and I remember my first time with a grinder by the name of Tony Sills. I've always remembered him because it was the first time I really noticed how low pros often hit balls... I recall wondering how the heck he could hit a three quarter SW or PW approach and it seemed like the ball never got 10' into the air, and then stopped like a ton of bricks on the green. My wedges were always sky high, and it made me start to concentrate on descending blows and hands forward.
I set up my old net in my new simulator area to get a better feel for my launches last night, and I was happy that my PW was hitting the net when trig would have suggested ceiling for sure. It gave me the confidence that I'll hit a 10' wall with my SW at 10' if I'm striking it well, and the ceiling will only come into play when I lay the blade open. I think I'm going to target 10' tee to screen, carpet the walls, carpet the ceiling. I'm shying away from a net at all unless it is a backstop for the screen.
I'd be interested in a straw poll of folks: how far from the screen is your tee?

I hit between 11 and 11.5 feet from the screen.

9 feet from screen.

The projector is right above the hitting area 9 feet off the floor, attached to the cage. This requires keystone correction on the projector to square the projected image on the screen. The projector could be quite a way further back without creating shadows, if the garage door opener wasn't in the way.

At this hit to screen distance, with a 9 foot high cage/screen , I can hit a full 56 without hitting the top of the cage. Worrying about hitting flop shots is a waste of time since you can hit a flop shot almost straight up if you open the face enough so you can hit the top of the cage no matter what distance to the screen you have. When hitting the top of the cage, skill at dodging bouncing golf balls is a valuable skill.unless you have really soft flooring material like shag carpet.
