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 GT2000HDR
- Cost-Effective Buyer
Under $1,200 at every retailer we track, and usually less at Amazon, for a real laser short-throw with 30,000-hour engine life. Compared to a lamp projector at similar price, the laser eliminates lamp-replacement cost over the practical life of the build.
- Recreational Player
Plug-and-play setup, with screen-ratio presets for common golf screens and an IP6X dust rating that suits a dusty basement install. Honest 1080p that looks fine on a typical impact screen.
- Space-Constrained
0.496 fixed throw fits tight rooms — about 3.6 feet from a 100" screen. The right projector for low-ceiling, short-depth builds that can't accept the BenQ TK710STi's geometry.
