Is Scubajet still in business?
Just a heads up for anyone thinking about buying a DPV from Scubajet, they declared bankruptcy last week. Yes, the purchase of a personal submarine is entirely feasible.
How long does 1 scuba tank last?
The duration of the air supply in a scuba tank depends on the factors mentioned above. Typically, an average scuba tank filled to 200 bar (3,000 psi) can last for 30 to 60 minutes at a depth of 10 to 18 metres (30 to 60 feet). The main reason why the recreational diving depth limit is 40 meters/130 feet is safety. Yes, you can exceed this point, but you need technical diving skills to do that. Beyond 40 meters/130 feet, it is necessary to make decompression stops and even use different gas mixtures, depending on the depth you reached.For recreational scuba divers, most diving agencies recommend a maximum depth limit of 40 meters. This limit is in place for safety reasons, and diving within these boundaries is deemed relatively safe, provided recreational divers have the appropriate training and equipment.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.Only twenty-six people are known to have ever dived to at least 240 metres (790 ft) on self-contained breathing apparatus recreationally. The Holy Grail of deep scuba diving was the 300 metres (980 ft) mark, first achieved by John Bennett in 2001, and has only been achieved five times since.How deep do you go? With the necessary training and experience, the limit for recreational scuba diving is 40 metres/130 feet. Beginning scuba divers stay shallower than about 18 metres/60 feet.
