No Octo while diving with redundant air supply

[tursiops]

You don't donate the BC inflator.. LOL, that is for your personal, very last ditch option.

ANY breathing from your BCD/Wing is a bad idea. Good chance of a lung infection.

Have you tried it? You do NOT breathe from the wing or BC! You are breathing just from the inflator.

To clarify; this is an Air2:

It is placed on your BCD/Wing inflator hose. You can breathe from it and it can be used as an (inferior***) backup regulator.


*** hopefully not using a Schrader valve as they cannot supply sufficient gas in a panic. Do they require a specialist connector (in the pic?)?

 

[johndiver999]

Yes an air 2 uses a high flow connector.

in a really bad situation, you can get air from a standard inflator by just pressing the deflate and inflate buttons at the same time-

I do not agree....if there is air in the wing/BD, some of that will be part of what you are breathing because ther is not enogh air flow from a standard BCD inflator.

So, although some in this thread keep coming back to an Air2, that was NOT in the OP and is NOT the issue I am addressing. I am objecting to any breathing from a standard inflator, whether you are pusing the air-in button or not.

Absolutely.

Literally only breathe from your BCD/wing if the only other alternative is imminent drowning!

So you,ve never tried it I guess?

The SDI book Solo Diver recommends a single second stage per first stage as did my instructor of the time. An Air 2 type alternate is just yet another failure point and I would NOT use such for a solo mission. However, if buddy diving and then I decide to do a solo dive off the beach I would not remove my secondary just for that one or two incidental (shallow, benign conditions) solo dives.

And I just bought a DGX BCI but not for solo. I bought it for travel (buddy) diving where I will be doing a lot of doff and don to clamber back aboard a bouncing Zodiac RIB in 6 feet swells with the deck hand trying to pull me aboard by my second stage long hose choking me with the wrapped long hose and pulling my mask off that I had put below my chin! I would never use such a thing as a solo diver. My primary will be on a 4 feet long hose under my arm and that will be donated to my OOA buddy.

A couple of years ago, I was NOT solo diving but my insta-buddy and the remainder of the group lost me and thus wound up with no buddy and nobody. I had a primary failure aspirating seawater and a laryngal spasm closing my airway. I then drowned. When I undrowned myself, I went to my secondary, an Oceanic pancake second stage which it began free flowing intermittently. It was woefully inadequate. I wished I had my pony with a real Mark 5/G250 on it. So, then, just buying the DGX BCI, you can bet I have my eye of dubious suspicion cast upon it as a very narrowly niched regulator in my diving kits. Being as I doubt I could undrown myself a second time.

This is a back mounted pony bottle configuration? If not, how is it related to the question at hand?

Maybe you should let the OP answer the questions presented instead of assuming it‘s your position to determine what is or is not relevant to their situation. The question of removing a secondary off of the main cylinder has nothing to do with where the bailout is mounted. It’s about removing a regulator that the OP feels may not be needed or is removing something that the OP identified as being ”in the way”.

Why would I do something that might give me a lung infection?
