It allowed Cousteau and Gagnan to film and explore underwater more easily.
The invention revolutionized autonomous underwater diving by providing a compact, reliable system capable of a greater depth range and endurance than its precursors, and was a major factor influencing the development of recreational scuba diving after WWII.
