A complete golf simulator setup requires five essential components: a launch monitor to track your shots ($500-$20,000 depending on quality), an impact screen or net to hit balls into ($300-$2,000), a hitting mat to stand on ($150-$1,000), a projector or display to show virtual courses ($300-$2,000), and simulator software to create the virtual environment ($0-$1,000/year). Beyond these basics, you'll need adequate space – minimum 10 feet from ball to screen, 10 feet wide, and 8.5 feet high, though more is better. Additional recommended equipment includes an enclosure or side netting to protect walls ($200-$5,000), a computer to run the software (unless using tablet-based systems), quality speakers for sound, and proper lighting. Your own golf clubs and balls are essential. For a functional home setup, expect to invest $5,000-$15,000 for a quality mid-range system with decent graphics and reliable data. Budget setups can be done for $2,000-$4,000 but with compromises on immersion and features.
