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.

Better for AH500ST
- Space-Constrained
0.499 throw, among the tightest in BenQ's golf line (the LK830ST is 0.496): a 10-ft-wide image from about 5 ft, which suits a low or shallow room.
- Cost-Effective Buyer
Golf-dedicated laser features (Golf Mode, IP5X seal, 4,000 lumens) at $1,999 — strong dollar-per-feature when the room geometry needs the tight throw anyway.
