 In recreational diving terminology, in a bounce dive the diver descends directly to the maximum depth, spends very little time at maximum depth and ascends directly to the surface, preferably at an ascent rate recommended by the decompression model used, and making any necessary decompression stops.In commercial diving a bounce dive is any surface oriented dive, in which the diver is decompressed to surface pressure at the end of the dive and does not transfer to a hyperbaric habitat where the diver lives at pressure between dives and only decompresses at the end of a tour of duty.The duration of bottom time is not relevant in this usage.
