V1 is the proof-of-concept. Set up in one afternoon (Dec 10, 2022), playable the same evening. A Net Return-style enclosure (10' wide, black framed walls, impact screen panel across the back) sits on top of a putting green runner mat laid across the garage floor. Hitting strip in the middle. Tee box marked at one end. Projector on a tripod throws Garmin's home simulator software onto the impact screen. Garmin Approach R10 launch monitor tracks every shot.

This is the $1.8K version - pre-assembled enclosure kit, off-the-shelf BenQ short-throw projector, the R10 (which was $499 at the time), an HDMI cable run, and the mat. No permanent installation. Nothing bolted to the wall. The whole thing breaks down in 30 minutes if a car needs the bay back.

What it does well: actually plays. Garmin's app renders real courses (Bandon Dunes, St Andrews, Whistling Straits - see the Bandon Dunes Par 3 in the hero shot). Ball flight + spin + carry distance are accurate to within a few yards on full swings. Stats screen gives you club speed + ball speed + smash factor + carry distance + spin rate every shot. Good enough to genuinely practice.

What it doesn't: short-throw projection bleeds light around the screen edges. The mat slides if you don't tape it down. Projector tripod gets bumped. The whole thing felt 80% pro and 20% temporary - which is why V2 happened 15 months later. Scroll to the V2 tab if you want to see what "permanent" looks like.
