Stage Regs

[Levigarrett]

Pressurize travel bottle, turn off, tie off on gold line (main line in a cave) at first third, recover on exit, OPEN (duh)...

Apparently this is not the "only" way. That's why I'm questioning. I can't imagine swimming around with my slung or staged bottle open but I guess some are doing it and I'd like to know why they favor that approach.

Two different things.

Swim around with your stage open or closed: -your choice.

Tie stage off and leave it somewhere: turn off, tie off, retrieve, turn on.

hope this helps.

Did you just say 80% O2? Oh boy, here we go again.......... I kid.

Haha Nice! I would have said 100% but I just saw a thread that made me laugh about not using 100%

Regarding your preoccupation with stage reg free flow...are you solo diving? I suspect that if my team members are the calibre that I'd choose to be diving with (conducting the kind of diving where stage bottles are required) they'd notice my reg free flow and take appropriate action. When I dive with a slung bottle of any kind, the valve is opened on the surface, the lines pressurized and then the valve is closed until it's use is required. I could be reading your post wrong and if so I apologize in advance but are you diving with your stage bottles "on?"

I am not solo diving, but I do take the approach of self sufficiency/redundancy. To be clear I open my slung cylinder valve at the surface and shutoff my inline sliding valve at the second stage. When I deploy/gas switch I just switch the inline valve over to on and begin using it. I like using them so far since I don't have to worry about turning on the cylinder valve underwater.

Yes it sucked.

Here is where age departs from energy and enthusiasm. I am mortal. I am playing the game with the only life I will ever get.

Full cave.

Go for it brother diver, just don't kill yourself...

I hear ya buddy Great job on Full Cave!!

I do this ONLY if I am using inline shutoff valves at the second stage. If I am not using the shutoff valves then I will keep the cylinder valve shut after I pressurize the line at the surface. When I deploy I would just turn the cylinder valve back on.

Yeah, sorry for the confusion. I was incorrectly using the terms stage and sling as though they were the same thing. Thanks.

If your first stage freeflows will shutoff valve work as an over pressure valve by releasing the excess pressure?

If it will then it will freeflow as well essentially bringing you to square one if it will not the lp hose will be blown off your first stage due to high pressure and you will lose you reg which you could have used otherwise even if it flows

They could be the same thing...

No and maybe. When I referenced Free flow in my posts above I was talking about free flow because of the position of my Second stage (facing up) then it usually free flows when I am in colder water and deep. In my previous posts I wasn't referencing a free flow based on 1st stage failure. I hope this clears that part up. That is why I like the inline shutoff valve. It just takes muscle memory and training to remember to open when you deploy.

I am not sure if your scenario would be the case, but I am sure it's possible If I as unlucky enough to find myself in that position I would have to switch off to my contingency deco plan and use my backgas for Deco.
