VX Mounting maximum

[cvclub]

I have 12 foot ceilings so I plan to build a custom drop for the VX. The spec range appears to be 9-10.5 feet?? I am assuming that would be measure from the floor to the VX sensors? I would like to keep it as high as possible for aesthetics and lee potential for a collision. Any experience would be greatly appreciated.

I have a ceiling that's just over the 11' mark, and I dropped my VX to the 10' mark using a projector mount just to make sure that I was within the recommended range.

I looked at mounts but most had a friction length adjustment and I read where one person found their LM on the floor! So, I am making it with flanges and black pipe at a fixed length. Pro tee said I could go to 10.5 feet but I don't know if that's to the base or to the lenses. Have you entertained insurance or a protective cover?

I'm building a sim in a 12' height space. Does it work to have your projector and the VX both hanging from the ceiling? I'd be worried about a shadow.

[cvclub]

I was told that as long as there is not direct light into the VX it should be a non issue.......My VX will be about 10' 4" and my projector is about 7 ft behind and about 8.5 feet up from the floor

[vbcoach]

Ok, so your VX is further from the screen than the projector? I was worried about the projector being further behind the screen and the VX casting a shadow on it.

[cvclub]

VBcoach, my vx will be about 10' 4"" from the floor and about 3-4 ft from the screen. The projector is further back, about 14 ft from the impact screen. I was told that should not be an issue since the light is not aiming up into the VX.

[dw886]

VX (or other overhead LM) is typically 3' - 3.5' in front of the golfer (so probably 5-7' back from the screen. The projector is typically directly overhead or even slightly behind the golfer (10' - 14' back from the screen). If they are at the same height above ground (or from the ceiling assuming the ceiling is flat), the angle that the projector light takes will typically miss the overhead LM...

The further back the projector gets from the screen, the more likely the golfer is casting shadows when addressing the ball or swinging...

This is from the BenQ room planner, but probably illustrates this better than my description:

Thanks all. I'm building one in a new house with 12 foot ceiling height (16' 5" wide). Sounds like in the ceiling I need power and ethernet about 6 feet from the wall and power and HDMI about 12 feet from the wall? Does that make sense for 16' wide? Does the ethernet for the LM need to run to the PC or to my router? Appreciate any suggestions.

[dw886]

Ethernet from the PC to the LM - the LM connects directly to the PC via ethernet.
I'd also run ethernet to the projector - may be useful later, could be used for control, or projector network connection.

For your projector, determining distance is a science. Depending on the projector model that you choose, there's a Throw Distance. The screen size and the projector throw are used to calculate exactly how far away the projector needs to be for the image size to fill the screen.

Here's a calculator that would help you determine where to run the projector power and HDMI: Projection Calculator Pro - Projector to Screen Distance (projectorcentral.com)

[vbcoach]

great, thanks. In general, how far back do you think a good projector would need to be (ballpark) to throw a 16 foot wide image?

[deepakvrao]

Depends on the throw ratio. Optomas usually have .5 so lens will be 8 feet from screen to have a 16 across image.

Sorry guys but another question regarding mounting.

When they say max is 10 feet, is that from turf to camera or turf to mounting plate?


Also is the distance ahead of the ball of 100 to 110 feet depend on the height? Is it that at 10 feet it should be 110 and at 9 feet it should be 100? Or, are these independent of each other?

Top of your hitting surface to ceiling

... and is the 100cm forward of hitting area (in the 9ft example provided above), is that to the centre of the VX or to the front edge of the VX?

[ProTee United]

Centre of the VX. The difference between front and centre is about 3".

[deepakvrao]

So at 10 feet is it BETTER to have it at 110cm or is it OK anywhere between 100-110?

[ProTee United]

110 cm is a triangulated result of the camera's pointing down in an angle and the height of the unit. Based on this calculation there is no "between". However the hitting area is 65 x 55 cm so in theory there is always room for 10cm difference.
