Subject: Long Hose Methods

>>Stuffing the long hose is not safe<

Then what is - dying?

Stowed away - sure - stow it in your duffel bag.  Unless you give
"specifics" you're not making sense...  Where are you gonna "stow" it.
And, if it's not tucked tightly and loops protrude it CAN catch on
things both in wrecks and in caves and will.

Long hose wrapped is MUCH easier to deploy, especially in a high
stress situation or one in which you cannot use your hands (unstuffing
the long hose is impossible in this last scenario).  This was evident
from the first time I tried it.  BUt, people like to argue that
whatever THEY do is best, I've seen it.  You can immediately decant
about 4-5' of hose just by ducking your head and at the same time
picking up your spare reg that's around your neck.  Then, when you
have time a quick flick will get the hose out from under the canister.
This really is the simplest and most efficient way.  

>>Stuffing is not optimal<

>"Optimal" is certainly an issue: for favorable or desirable condition

Interesting that you think "optimal" is an issue but safety isn't.
I'd say you have your priorities backward here.

Behind his head - where all the valves and 1st stages and other hoses
are.  Or do you mean BEHIND the valves where it can REALLY get caught
on something???  Just think, the long hose is stuffed behind your head
so, as you deploy it, you rip the other reg (which you're already put
in your mouth) out of your mouth as the hoses get tangled.  I guess
the only thing that's scary is you're serious.  Why would you stuff a
hose where there are already other obstables to ensnare and tangle it?
Talk about non-optimal...  The diver without a light canister can
"tuck" that end of the hose under his belt.  But, why no light
canister and how close is he to rule #1???

Maybe someone like Dive Rite will invent a HOSE REEL so you can wind
it up :^)

Tuck it along side a cylinder???  Hmmm - I've banged tanks a few times
on walls, ceilings, etc - anyone here who hasn't please raise their
hands.  Anyone think that banging a HOSE isn't a good idea???

It only takes ONCE that you need OPTIMAL - why do it otherwise???
 
>>Unstowing the long hose<

>if any. If a chest strap or other piece of equipment where to be placed over

Not if you can't deploy it properly or if it's stuffed to tightly or
if it got tanged because it wasn't "stowed" tightly enough.  Geez,
what a nightmare, why bother.

>the long hose by accident this could hamper the deployment,  if the donor
>where in fact breathing from the long hose.

Putting the long hose under a chest strap would.
#1) be caught during the "S" drill when the hose must be deployed BEFORE
    you start the dive - or don't you do these???
#2) if done on purpose comes under rule #1.

>>Stressed diver ripps yours from your mouth, now pinned to you because of

>So what!   The hose isn't any shorter than what 99% of all divers learned
>their basic air sharing skills on.  The merits of the long hose is for ease

Sure, just use OW gear in the caves, on the wrecks - that's what all
divers learn from anyway.  What is your point here?

>of sharing gas while passing threw retrictions and to make moving easier
>for both divers.  Once the stressed diver calms down the correct regulators

It's ALSO for ease of deployment and recovery of your secondary.  If
you're in a restriction, your buddy is ahead of you and needs air, how
are you going to deploy a stuffed hose, and, what if it gets stuck
behind you somewhere while he's in front???

>can be switched (how much time is really lost?).  I think there would be a

Enough to die - is that enough???

Other than the ones I've mentioned, maybe not...

>>Forced compromise of some other part or your gear<

Extra hose or tie downs/etc somewhere needed to "stuff" or hold down
the long hose.  Potential entanglements with putting the hose behind
your head of your OTHER hoses.

On the INSIDE of a backplate.  That's crimping a hose unnecessarily,
making it difficult to deploy, susceptible to wear and tear.  No
thanks, why do you keep arguing an indefensible point?  

>> They are hard to free up, they are confused and messy<

>That could go for just about any piece of equipment. 

Maybe that YOU wear, but not me...

>>They clutter your dive gear<

>HOW?

A stuffed hose requires something to hold it in place - addition
attachment points, potential for snags, bumps, abrasions, etc.

>>It generally takes two to restuff<

>True but not always. But who says the hose has to be "restuffed"?  Why not

MORE IMPORTANTLY - it may take two to UNSTUFF!!!

So why not just breathe the long hose in the first place???  you've
NOT come up with ONE reason NOT to do this, you're only trying to
justify breathing the short one.

>>Not good planning<

>Planning for what? 

Emergencies...  Read above I really don't want to type it twice...

Really - and why don't you think side exhaust regs will free flow???
Fortunately on the Odin there's a +/- switch, but on others???  I
use the Odins for both sides.

More valves, O rings - why introduce failure points?

Ah, here's the crux of the situation.  If "technical" divers stopped carrying
all that unnecessary crap, they would be MUCH more streamlined...

>>Not the safest<

>Again this not a safety issue

Sorry, you're simply wrong, but I suspect you know that.
