  • Patent number: 4611809
    Abstract: A golf putting practice range apparatus includes a shooting area, a putting surface and a golf ball target hole at the down-range end of the putting surface. The golfer stands on the shooting area and hits a ball over the putting surface in an attempt to sink the golf ball into the target hole. The target hole is adapted to be selectively moved to present different target locations. Further, the putting surface is adapted to provide for selectively changing its contour. The practice range also includes a ball return system which returns golf balls back to the shooting area for reuse. In one embodiment the golf ball target hole is selectively movable linearly transversely of the longitudinal axis of the putting surface. In another embodiment, the putting surface includes a plurality of planar panels hinged together at their edge-to-edge interface.
