Deepest saturation dive [Experimental]

Last updated: May 11, 2018 at 2:05 am

701 msw (2,300 fsw) — COMEX Hydra 10, Hyperbaric Experimental Centre, Marseille, France, 1992. The dive protocol required a four-week pre-dive period, two days confinement at 10 m (33 ft), 13 days to compress to 675 m (2,215 ft) breathing hydro-heliox (a.k.a. hydreliox) (hydrogen 49%, helium 50% and oxygen 1%), and three days of bottom stage between 650 m and 675 m. One of the divers, Théo Mavrostomos, then moved into a separate chamber and continued to 701 m (2,300 ft) for a period of seven hours. The record experiment required 24 days of decompression followed by 2.5 months post-dive monitoring. The experimental dive followed COMEX’s Hydra 8 openwater record saturation dive in 1988. (msw = metres sea water) (fsw = feet sea water)
