Deepest "dive" in a hyperbaric chamber
Theo Mavrostomos
France ()

In November 1992, French diver Theo Mavrostomos achieved for the deepest dive on dry land. In a hyperbaric chamber – of the sort used to re-acclimatise deep-sea divers to surface pressure and prevent them developing the bends – Mavrostomos survived a pressure equivalent to that 701 m (2,299 ft 10.37 in) beneath the surface of the ocean.
