Though that’s what most fitters I’ve seen used. But the new Trackman IO is supposed to be optimized for indoor usage and mounts to the ceiling. I haven’t decided yet but it looks pretty appealing to have something off the floor for me because I have young kids.
Although, I’ve seen enough discounts lately on the gcquad that it would be hard to pass up. By the time I’m buying I wouldn’t be surprised if you could get one for less than $10k.
