You breathe compressed air when diving with airbuddy. But it is possible that one of these molecules could replace the oxygen tank in rebreather diving or in other mixed gas diving where the pure oxygen is diluted with other gasses such as nitrogen and or helium. Smaller than an aluminum tank of the same capacity a steel scuba tank is a more compact air supply solution a fact that becomes doubly important for twin tank setups.

It constitutes 21 percent of air but we can change the concentration in our tank for nitrox or trimix diving. The maximum depth reached by anyone in a single breath of air is 702 feet without any injury.

You must therefore learn the diving theory understand the risks and develop safety skills e g. For this reason recreational scuba divers never dive on pure oxygen as this would be problematic in even very shallow water. Freediving free diving free diving breath hold diving or skin diving is a form of underwater diving that relies on breath holding until resurfacing rather than the use of breathing apparatus such as scuba gear.
