Underwater diving is the practice of descending below the water's surface to conduct underwater activities. In ambient pressure diving, the diver is exposed to the pressure of the surrounding water, and uses breathing apparatus for scuba diving or surface supplied diving, or when freediving, will breath-hold. The saturation diving technique reduces the risk of decompression sickness after long duration deep dives.
An average scuba diver can stay underwater for 45 to 60 minutes on a 40-foot dive. Many factors affect tank duration, including depth, tank volume, and the diver's air consumption rate.
