What to remember
No ocean for this one, only a hyperbaric chamber. In 1992, during the Hydra 10 experiment, Théo Mavrostomos spent two hours at a simulated depth of 701 m, or 2,300 ft.
The depth was simulated: the experiment took place in a chamber, not in open water. The figure on record is that simulated depth, held for two hours.
The record belongs to deep diving, meaning diving beyond the range normally accepted by the diving community. Depending on the case, that limit is set by an authority or tied to a level of training, and it differs between recreational, technical and commercial diving.
