Golftec (disclaimer - don't know anyone working there) was something I never looked into, probably confirmation bias or the social media out there about the hard sell to buy lesson packages. After trying out its video setup, the benefits of having both face on and down the line views simultaneously was intriguing, and a screen where you can see yourself live although you still have to manipulate your head to see the screen, VR goggles not available yet but you can bet that will be a thing in the near future, could be useful for some I thought.
Winter was a time where practice wound down, don't know anyone with a large relatively warm space (Hey buddy, you have so much photography/music studio loft space you could easily fit in a net there and we could practice during winter! Whadday think? ) where I could plop a net, and paying for a simulator when I wasn't using the simulator, just videoing myself, plus groups using simulators tend to be noisy, just didn't work - too limiting and expensive. Places w/simulators can be cramped spaces too, so you may not get a face on or down the line camera view. Practicing during the winter outdoors was getting more and more to be a drudge - it's one thing to swing, futzing with a camera when it's cold is the dealbreaker, even with touchscreen gloves.
So finally the plunge into a 1/2 year practice plan was made. If you go 2-3 times a week, the cost per visit goes down considerably compared to simulators. What I didn't anticipate is that dual video cameras has been more beneficial than I imagined, the connect between what I'm doing and what really happens is much more immediate, even though I've been using video, "only" one camera - and I think I'm making better progress because of it and now that plunge is looking like a great deal. So if you're looking for a place to practice in the cold winter, take a gander into any company/facility with dual cameras and multiple locations. You might get in some considerable swing work done during the offseason.
