IFF you don't use an air 2..
Oh please don't.

Basically you have to hug the other person in order for them to breathe from your BCD/wing hose. Not a nice option.

An Air2 IS another regulator, so needs testing and servicing.


A standard longhose + necklaced backup is all you need. Two regs, both for you and should you need it, one for someone else with a standardised donation procedure.

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.
 
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?)?

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-

Have you tried it? You do NOT breathe from the wing or BC! You are breathing just from the inflator.
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.
To clarify; this is an Air2:

Yes an air 2 uses a high flow connector.
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.

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.
