My sim golf path has been r10, skytrak OG and now the square and have always used GSPro.
Wow this unit is unbelievable for the price and I'm sure future updates it will get even better.
The putting and small greenside chips seem to read very accurately. This alone is a massive improvement from the old skytrak OG.
The only thing I'm a bit worried about is a lot of friends and family use my sim and the odd slice is probably going to happen. I have the offical case but I think I need to come up with something else.
The team at Bay side Golf have been great, I contacted their team a couple of times and they were super helpful.
