  • Patent number: 4799725
    Abstract: The present invention relates to a golf ball retrieving device for removing golf balls from water hazards and other areas that otherwise would be difficult to access. The device comprises a uniquely shaped net particularly adapted to be removably attached to an end of an existing ball retriever having an extendable shaft. The net and frame are configured and arranged so as to easily retrieve golf balls from water hazards even when the golf ball is not in plain view. The device effectively sweeps a substantial portion of terrain as it is retracted toward the user enabling the user to retrieve golf balls that are contained in that area. The frame is configured to discourage weeds from entering and obstructing the net.
