Inaccurate– What most people look for in golf simulations is a way to play the actual game in the comfort and convenience of their own home, and a simulation should feel like the actual game, says Golf Digest. You should not expect anything other than a true simulation when you buy one of these devices, and if you aren’t getting that, then you need to look for a different simulator. Once again, reviews are your friend, and you can use them to tell you what simulators offer the real deal.
We strongly suggest staying away from the very inexpensive (under $100) or “mini” projectors that seem to be popping up everywhere. The reason for this being that most cheap projectors lack the brightness (measured in lumens) needed to display a good picture in anything brighter than complete darkness. Remember, the brighter you want your simulator bay the stronger you need your projector to be. After all, no one wants to swing in the dark!
I've had this for a couple weeks now and have played a few rounds on TGC. Pretty fun. As others have noted, this won't register fat and thin swings. My distances also seemed off (short 15 to 20). Adjustments to the club's loft and shaft length (from head to bottom of sensor) helped dial my real distances I guess by changing club speed. It seems like path and club angle at impact are accurate. Can't really tell on side spin and have toed some swings that register as straight shots.
The benefit of using a system like OptiShot is that you don’t need to use an actual golf ball. You can use a foam ball or a plastic one. This will allow you to save a ton of money because you don’t need to use a high impact projector screen or net. Cory has seen some people use painter’s tarp or a bed sheet, which will save you several hundred dollars.
