What equipment do divers use?

In recreational diving you use one scuba tank, but tec divers typically wear twin cylinders or closed-circuit rebreathers (CCRs), plus one or more additional tanks, each with different gas blends. They usually have two or more completely independent regulators and dive computers, as well as other dive gear backups.

How do divers breathe underwater without oxygen tanks?

Alan Izhar-Bodner, an Israeli inventor, has developed a way for divers to breathe underwater without cumbersome oxygen tanks. His apparatus makes use of the air that is dissolved in water, just like fish do. (From Breathe like a fish!)

How long do you have to stay in a decompression chamber?

Side effects and possible complications of HBOT. During HBOT, you lie on a table in an enclosed chamber and breathe oxygen while the pressure inside the chamber is slowly increased. The therapy may last as little as 3 minutes or as long as 2 hours before the pressure is returned to normal levels.

Can you explode in a decompression chamber?

It is possible for a person to effectively ‘explode’ in the event of an explosive decompression, but only if the pressure differential is significant. A chilling example of this is the Byford Dolphin diving bell accident*, where divers were decompressed from 9 to 1 atmospheres.
