I'm not studying to be a dive master must this stuff is fascinating

Really, I can't thank you enough for making this video.. I watched a few other videos online that gave me a touch of info here and there, but this was the help I really needed in tying them together and answering most of my questions. I mean really, as it stands now, it does not get any better than this video and I hope others understand it as well because it's awesome.

this is an amazing video, you learned me in half an hour what I couldn’t understand even after reading it over and over again in hours!!

Thank you very much!! I have been certified for the repair and service of the regulators of a few major brands and have been doing the work for quite a few years already but watching your videos still benefits me a lot from your clear and systematic explanation!!

Best video on KZfaq. When I was a DM, one of my drivers crashed the top of his tank while going through a swim through....mental. of course he was fine....abit shaken up and fortunately I had a DMT with me who took him back to the boat and the rest of us carried on with the dive after meeting up at the service!

thank you for sharing your knowledge in a simplified way. great effort

Great video and tutorial. Thanks

ITS A REALLY GREAT GREAT VIDEO! THANKS SOOOO MUCH,IT HELPS ME A LOT TO UNDERSTAND HOW SCUBA REGULATORS WORK!

Bravo!!! Very simple and clear. Genial!

thanx. I was missing some info till now. I'm greenhorn in diving but it does not mean that i'm greenhorn in tech. :) so please future instructors - be precise in what you're saying :)

thank you^^ 感恩^^🎉

Keep up good work very informative video good work guys

Keep it up guys, will be waiting your second video for the second stages.

Very helpful. Thanks 🙏🏼

Great, thanks!

What I cannot work out is how the first stage "cycles" through inhale/exhale in the story you give. Surely, the moment that you begin to inhale, the first stage "opens" but, as soon as it is "open", it "closes" again because of air pressure differences. If this is the case, does it "vibrate" between the "open" and "closed" states as the diver inhales?

At 12:40. Seriously ? I just can't believe that a diver would crash his reg into a overhead situation. Enough to dislodge the first stage. Every Instructor tries to throw in their own unique way of teaching. Running off down the road with very rare possibilities of what can go wrong. It's Overkill man. Keep it simple. Your filling up your teaching with extreme highly improbable scenarios...
