If you have a DIN regulator and a dust cap with a flat sealing surface for the DIN o-ring to seal against then you can soak your 1st stage without it being pressurised with no worries as long as that cap is on properly. That said, most DIN dust caps do not have such a surface and, in addition...

I replaced the jacket part of my whites Mk II with a long sleeved Lavacore vest underneath my jumpsuit and love it. It's much warmer and gives me much less bulk on my arms so better comfort and mobility. On the first dive I tried it out I was flushing my hood for the first 15 minutes of a dive...

I'm not sure what his schedule is like currently but the best starting point for anyone wanting a damn good edumacation in tec diving would be Monty Guest. You can get hold of him through the False Bay Underwater Club. Failing that Alaistair Downing of Underwater Explorers might be able to...

The reference to 300 bar is the hydro pressure.

DSS offers a cinch system as well. All you need to do is spend $40 to buy this: https://www.deepseasupply.com/index.php?product=1340 and you are good to go. Now, $460 + $40 sounds a lot more reasonable to me than ~$1000. Especially considering that there is no difference in quality, function or...

Edit: random rambling is bad mkay ...

Is that a corrugated hose I see for oral inflation? Awesome!

Thank you but that doesn't answer my question. I am very well aware that there is no such thing as an ideal gas in nature. Underlining for emphasis. I very, very deliberately and consciously phrased it that way to avoid nitpicking.

Wow! Cool! :thumbs-up I have some reading to do. :cool2:

Woah dude! Chill! That's an awful lot of aggression you are showing for, quite frankly, relatively very little provocation. Scubaboard is here for our enjoyment, not to ratchet up our blood pressure. Think of hanging weightless surrounded by fish, sharks or whales. Peace. Relaxation. Bliss...

Well then, those commies are just as strange as you cubic feet lot too. I breathe in litres! :D

Thank you but that doesn't answer my question. I am very well aware that a pressure differential is needed for gas to flow from one container to another. Also, at what pressure does helium stop approximating an ideal gas and start behaving as a real gas?

If you are responding to Wookie, I believe that he mentions a 12.2L 232 bar cylinder as an example of a metric cylinder whose actual volume gets shortened in order to save breath in a manner similar to the way in which Ali80s are shortened. I do not think that he was actually saying that they...

If you were to pinpoint one quality, attribute or habituated activity that all humans share, what would it be? I am not talking about biological imperatives. Yes, every single human being breathes, excretes, sweats and sleeps but this is by necessity rather than choice, cultural conditioning or...

I also struggled to helicopter and back kick in Novas. Bear in mind though that my experience was within the time frame of a single dive so I have no idea if I could have adapted a style that worked with them over time. I found that whenever I tried anything other than a flutter or frog kick...

Yes he is. As stated in the OP he currently has no tech gear and, to elaborate, has no experience in anything other than the "normal rec" configuration or techniques (stab jacket, short hoses, flutter kicking like a mofo and so forth). Which is another of my concerns. He will definitely be...

Heyas guys and guyettes. :D I'm not a cave diver nor do I have aspirations to becoming one in the near future however I am an avid reader here and on other tech orientated forums. I have come here to ask for your help with a friend of mine. I was recently bemused to read his Bookface status...

Ah, that makes more sense. It's funny how a simple 'g' can make all of the difference. ;) Thanks for the clarification. Little distinctions like that are important underwater.

This post, along with just about every other post you have contributed to your thread, just details exactly why you SHOULDN'T be doing this. If your compressor only delivers 17 psi then there is no way in hell it could be rated to 5m ( ~15ft). At 5m the ambient water pressure is 1.5ata (...
