    Abstract: A frame held in an operative position, and used to mount a resilient energy dissipating surface. The resilient energy dissipating surface having at least one aperture, defining a target area, in communication with a hollow resilient energy dissipating sleeve. A hollow resilient energy dissipating sleeve having two ends, the end opposite an aperture in the resilient energy dissipating surface being open and in communication with a golf ball retaining receptacle. In the alternative, or additionally depending on the number of apertures and corresponding sleeves present, an end opposite an aperture in the resilient energy dissipating surface may be closed for storage of golf balls within a sleeve after the golf balls have entered an aperture in the resilient energy dissipating surface. Furthermore, the frame can be constructed to be collapsible for easy transportation and storage.
