Why DIY looks easy
The videos make it look like a weekend project. A box arrives, the frame goes up, the screen gets clipped on, the projector goes on a shelf and someone hits a perfect drive into a famous fairway. It can go that way. More often, the trouble starts in week two, when the picture has a shadow, the numbers feel off and a ball comes back off the screen faster than it went in.
What comes in the box varies by brand and package. Some include a projector and some do not. Foresight's SIM IN A BOX, for example, ships without a computer. Read the parts list closely before you compare prices.
What goes wrong in a DIY build?
These are the most common problems in DIY builds. None of them are about the launch monitor itself.
Why did the club hit the ceiling?
The room was measured with a tape, to the drywall, in one spot. The duct over the hitting area, the thickness of the mat or the garage door track was missed. We scan rooms with LiDAR and model the swing of the tallest golfer in the house before anything is ordered. Our room size guide explains what to measure.
Why is there a shadow on the screen?
The projector was mounted where it was easy to mount, not where it belongs. If it sits behind and below the golfer, your body blocks part of the image at address or at the top of the swing. Throw distance, mount height and the hitting position have to be set together.
Why is the picture washed out?
Daylight from a window, a garage door panel or the wrong overhead lights can wash out even a bright projector. The projector also has to match the screen size and the throw distance. Getting the lighting right is half of a good picture, which is why we design it with the room. Our room design guide covers it.
Why does the ball come back at me?
Impact screens need the right tension and a gap behind them. A screen stretched too tight or hung too close to the wall sends the ball back toward the golfer. Side netting and the enclosure also have to catch mishits before they reach a wall or a window.
Why do the numbers feel wrong?
A launch monitor that is slightly off level, aimed a few degrees off the target line or fighting the room's lighting reads every shot a little wrong. The brands we install are accurate enough that club fitters rely on them, but only when they are calibrated for the room.
Why does the software stutter?
Simulator software is demanding. A computer below the recommended graphics specs drops frames, and a weak wireless connection drops updates and online play. We supply computers built to the manufacturer's recommended specs and hardwire the network.
Why can they hear it upstairs?
Every shot hits the screen with a crack. In a basement or a room over a bedroom, that carries. Insulating the ceiling bays and choosing the right screen and enclosure keep the peace.
Why did it stop working in January?
Electronics have minimum operating temperatures, and condensation forms when a frozen garage warms up. Our cold garage guide explains what to do about it.
Who do I call when it breaks?
With a DIY build, the answer is a different support line for the launch monitor, the projector, the computer and the software. Each one will tell you the problem is somewhere else. With us, it is one number and managed service that covers remote monitoring, updates, seasonal recalibration and on-site visits.
What DIY really costs
The box price is only the start. A typical DIY build also pays for:
- A computer that meets the software's recommended specs, if the package does not include one
- Mounts, blocking and cable runs for a ceiling projector or launch monitor
- An electrician for new circuits, and in a garage, heat
- Patching and repainting when a mount moves
- Return shipping on a screen or enclosure that does not fit
- Your own time, which is often several weekends
For comparison, our standard installation of a Foresight SIM IN A BOX is $2,500 to $5,000. Our cost guide breaks down the full budget for packaged systems and custom rooms.
The middle path
You do not have to choose between doing it all yourself and a fully custom room. You can pick a packaged system, buy it through us and let us handle the parts that go wrong in a DIY build: the measurement, the mounts, the projector alignment, the calibration and the service. You can price a package on our SIM IN A BOX page, with installation and a PC added in one click.
If you already bought one, call us anyway. We can often install a system you purchased yourself, and we will tell you honestly if a piece does not suit your room before you open the box.
Before you order anything
- Measure the ceiling at the lowest point over the hitting area, including ducts and beams.
- Test your own driver swing and the tallest golfer's.
- Decide whether lefties and righties will share the bay.
- Check what is in the box and what is not, especially the computer.
- Plan the projector position before you hang the screen.
- Count the circuits you have and the ones you need.
- Try your numbers in our 3D room fit checker.
