An introduction to the use of multiple gases in technical diving and how they allow reaching depths not possible with regular air.
Multiple gases are the key to technical diving and understanding them opens the door to impossible depths.
Air with a higher oxygen content extends the safe diving time at intermediate depths.
A mixture of oxygen, nitrogen and helium. Helium reduces nitrogen doping and enables greater depths.
Every diver wants to exceed 40 meters with real safety.
The right gas can take you to depths you wouldn't dare reach with regular air.
