Room planner
See each one in your sim room.
The planner draws each unit to scale with your room and your swing: where it mounts, the throw it needs, and whether your shadow crosses the light. Put in your room once, then switch units in the planner to compare.
Build your simulator in two minutes
Five questions. One tailored build with retailer links.
We ask about your budget, your room, and how you’ll use it. We return a complete build — launch monitor, mat, enclosure, projector, software, PC — with the reasoning behind every pick and the alternatives we considered.
