The author discusses the first commercial use of prolonged deep diving techniques that was held in 1967 at Smith Mountain Dam in Virginia. Jack Clotworthy of the Westinghouse Underseas Division provided funding assistance. The Westinghouse CACHALOT system is consisted of a Deck Decompression Chamber and a Submersible Diving Chamber with complete support equipment. The author says the breathing apparatus is an alteration of the Navy Mark VI semi-closed mixed-gas gear.
