ABSTRACT:
A submersible grappling system is designed for retrieving objects, such as, golf balls from the bottom or floor of a body of water and is made up of a tubular housing, a bladder at one end of the housing, finger-like retrieval elements at the opposite end of the housing and a gear column which serves to interconnect the bladder and retrieval elements so that when the gear column is driven in one direction, it will cause the bladder to be compressed within the upper end of the housing while forcing the retrieval elements downwardly and outwardly into surrounding relation to an object to be retrieved, and when the gear column is driven in the opposite direction will cause the bladder to be expanded upwardly away from the housing to increase the effective buoyancy while causing the retrieval elements to be retracted around the object and drawn upwardly into the housing.
