This video is my 4-year DIY golf simulator update — the full walk-through of what I’m running today, what’s changed over time, and what I’d do differently if I was starting from scratch. I break down the “big rocks” that actually matter in a home sim: your screen/enclosure, projector choice and placement, your turf and hitting surface, and how to keep the whole room feeling clean and functional without lighting money on fire. I also share the no-BS advice I give people every week when they email me about builds: match the projector to your throw distance and mounting options, don’t cheap out on the parts you physically interact with (turf + hitting area), and plan your space like a real room — cable management, PC placement, and access for maintenance. I call out the exact gear I’ve used and recommend (BenQ short throws, Carl’s enclosure options, Money Putt Turf, and launch monitor choices) and why each one makes sense depending on budget and goals. If you’re trying to build a “dream sim” that still feels realistic and holds up over time, this is the blueprint.
