Downswing Supply Co. exists because shopping for a home golf simulator is harder than it should be.
Every configurator belongs to a retailer that only shows you their inventory. Every "top 10" list is stuffed with whoever pays the highest commission. Meanwhile you're trying to answer basic questions: will a driver clear my ceiling, does my room have the depth for radar, and what does a build I'd actually be happy with cost?
So we built the tool we wanted: a free 3D room builder that lets you plan your simulator room to scale with real products from any brand — Garmin next to Carl's Place next to SIGPRO — with a live cost total and no thumb on the scale. It recommends nothing. You build what fits your room and your budget, and every product links to the brand's own site.
The honest part: some of those links are (or will become) affiliate links, which means we may earn a commission if you buy — at no extra cost to you. That's how a free tool stays free. It doesn't change what appears in the builder or how anything is ranked, because nothing is ranked.
Beyond the builder, we publish practical guides on room sizing, budgets, and low-ceiling setups, and we make a small line of Downswing gear for golfers who'd rather be at the range.
