As a new diver with only six dives about to complete my open water Sunday the eighth for my certification I have been binge watching your videos and I have learned so much on how and why first stages second stages, low pressure, intermediate pressure how the technical part works, although I do not plan on being a technical diver it’s nice to know how these things work These videos that you have posted throughout the years are invaluable

[jacquespoirier]

nice explanation
you, re an excellent teacher
it is a shame that this type of generic information is not a part of basic diving certification
Top me, it is asafety concers as such a knowledge car prevent a panic situation in the case of an equipment that is not performing as it should..
excellent topic
very good video

Excellent video, I have a question. I suppose that the air pressure is at 150 psi when the air gets outside the filter?
Or at least in the first chamber before reaching the diagram? Thanks!
