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.
The Deepest Dives With the right training, equipment and breathing gas, scuba dives have been made to great depths. The current record for an open circuit scuba dive performed round trip from the surface is 318M (1042 feet).This dive required over 8 hours of decompression stops during the ascent.he Longer Answer-Pretty Darned Deep Scuba diving, however, is not limited to recreational diving. Self Contained Underwater Breathing Apparatus (SCUBA) allows technical and commercial diving to depths well in excess of 130 feet. Humans reach a physiological limit of about 210 feet using normal air as a breathing gas.
