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 GT2300HDR
- Cost-Effective Buyer
A laser short throw for $1,099, with no lamp to replace. About what the GT2000HDR costs, rated 3,600 lumens (ISO 21118) against its 3,500 (Optoma states no standard for that one), with a Golf Sim mode it lacks, and $200 under the GT2400HDR.
- Space-Constrained
The 0.496 throw puts 100 inches up from about 3.6 ft, the same tight geometry as the GT2400HDR.
