What's the use of a breathing apparatus for diving supplies?Can you use oxygen in the water without the oxygen bottle? Watching TV people in possession of a tube swimming in the sea, I do not know can not breathe oxygen. Know how to say "ah"!!!!
That's impossible. There must be an oxygen tank under the water, unless he's a superman or a mermaid.
The breathing tube can only breathe on the surface of the water. Under water, it is only a breath holding dive. There must be an exaggeration to watch on TV. It is really necessary to wear a breathing apparatus under water
The exhalation tube is used in shallow water, and a section of the pipe runs in the mouth, which must be on the water.What you said could not happen in twenty-first Century. ~
