How long does a 3000 psi scuba tank last?
Total time = Tank capacity / Air per minute. Using an 80 cubic foot tank at 3,000 psi: A diver with a SAC rate of 0. With an 80 cubic foot tank, they’d have about 53 minutes of dive time (80 / 1. Most recreational divers rarely dive deeper than 130 feet. But commercial divers can use atmospheric suits to descend to depths up to 2,000 feet. Some recreational divers have descended to depths of 1,000 feet and beyond and survived the experience without any problems.Diving to a depth of 300 meters, or 1,000 feet, is the “holy grail” of deep diving. In 2001, a diver named John Bennett first achieved this depth, and the same depth has been reached just a handful of times since. The deepest dive in the world ever made was by the Egyptian Scuba Diver Ahmed Gamal Gabr in 2014.From Table 1 or Table 3, the No-decompression Limit for 80 ft is 40 minutes. Subtracting our Residual Nitrogen Time from the No-decompression Limit, we get an Adjusted No-decompression Limit of 40 – 18 = 22 minutes for our second dive.Saturation divers work at depths as great as 1,000 feet (304 meters). If they used the same technique as recreational divers to safely decompress — slowly ascending with long pauses — it would take them days to reach the surface.
