The installation additionally includes a multiplicity of balls, or other projectiles, and a recovery unit that recovers the balls that fall through the net and into a funnel-shaped portion thereof and conducts the balls back to the land based portion of the driving range. The recovery unit includes a submerged ball return conduit connected to the funnel shaped portion. Spaced valves in the conduit form a compartment which may evacuated by air pressure. Golf balls roll down the conduit by gravity to a recovery chamber and are lifted to a land-based station by a conveyor.
