Why give primary instead of alternate regulator?

[wetb4igetinthewater]

Yup. Maybe it's because I'm tall (6'2"), but a 5 foot hose would be much too short when routed in the standard long hose, primary donate configuration. And I stay the hell out of caves.

Too short for dry suit diving for a shorter person as well.

Dunno how I missed this thread. But it made me think.

Here is my ha'penny's worth **
An new OW diver. In said situation.

I check my pressure ( a lot ) I am at 50 bar. Buddy ( never more than 3 body lengths away ) OOA's so races over to me an tries to grab my Reg in mouth. No. It's My Reg in My mouth I am breathing from......here is my Alternate-stuff it in yr gob n calm down...there.... OK, yr out of air an we are at less than 20m, 50 bar, we both breathing -yr ok, I am also ( cuddles may occur ) so a nice steady slow ascent ( watching my Puk on wrist )....there.. OK an here is the surface... K



**US divers this is called 'two cents'

What if your alternate isn't breathing well for some reason? How often do you test it? An OOA diver hasn't taken a breath for awhile, so may be near panic. Why not give him a reg that you know is working?

I stand 170cm (is that 5'8" in your units?) above ground and am quite happy with my 150cm (5') long hose.

I'm not very surprised that body size affects which hose length that fits best.

Not for this shorter person.

That's a surprise as someone who was about your height, 5 feet was too short for him. He was quite uncomfortable.

I guess that girth, drysuit fit, and undergarment type and thickness might play a role as well

I want the one I know is working. Call me selfish, but if the idiot cannot manage to have enough gas or maintains their kit they can live with whatever bit of rubbish they are enough lucky to get

Personally I test both my regs in the buddy check and want to see both my buddies regs tested. But suppose we are left with one gas source between us, are you seriously saying I give that away?

Agreed. But given where you dive, I would guess that you have pretty lofty undergarments. So even if you were a beanpole, your drysuit/undergarment would give you some girth.

It's in yr Buddy check ! 17 dives an I know this! Both sets of regs WERE working when we got into the water.....or We Would Not of Got into The Water... k
