An introduction to using multiple gases in technical diving and how they allow reaching depths not possible on ordinary air.
Multiple gases are the key to technical diving, and understanding them opens the door to depths that are not possible otherwise.
Air with a higher oxygen percentage that safely extends dive time at intermediate depths.
A mix of oxygen, nitrogen, and helium. Helium reduces nitrogen narcosis and allows greater depths.
Every diver who wants to go beyond 40 meters with real safety.
The right gas takes you to depths you would not dare on ordinary air.
