Simulator technology is fundamentally reshaping how golf is taught, learned, and scaled. What was once a supplementary training aid is now a core coaching infrastructure enabling precise measurement, instant feedback, and year-round player development across all skill levels. As launch monitors, high-speed cameras, and AI-driven analysis converge, instructors are evolving from feel-based teaching to fully data-informed coaching systems. This session explores how simulator environments are redefining instruction, improving outcomes, and unlocking new business models for coaches and academies.
