Abstract : The patent describes a multiple retrieval system for objects placed on the sea floor for extended periods of time comprising holding means and three retrieval means. The first retrieval means is a vertical line system, the line being fabricated of titanium monofilament fastened to a cast-steel ball anchor at the lower end and a syntactic-foam globular buoy at the upper end which is some 50 feet below the ocean surface. The second retrieval system comprises a 5200-foot length (approximately) of polypropylene-jacketed, aluflex line extending from said cast-steel ball anchor to a frame for holding the submerged object. The third retrieval system comprises a 5,000-foot length (approximately) of polypropylene, self-buoyant rope extending from the frame to another cast-steel ball anchor.
