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
- 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.
Better for UHZ35ST
- Performance Seeker
Low input lag (about 17 ms at 4K/60, level with the TK710STi) and a 30,000-hour laser. At 3,500 lumens it is dimmer than the GT3900UHD and ZK431ST-B, which both cost less.
- Family Setup
4.4 ms at 1080p/240Hz for fast games, 4K for movies, and a Golf Sim preset. The GT3900UHD offers the same low 240Hz lag (4.3 ms) and a golf mode for $700 less.
Both fit
