Hogarthian configuration question

[LiteHedded]

During a routine dive, which piece of equipment do you use more often, the inflator or the reg on the necklace? The inflator of course. If you experience a roll off, the lack of inflation would indicate this much earlier, and without near the stress, of waiting until in an OOG, to find out that your backup reg has no gas supply.

This is the reason I supply the inflator from the left post.

Edit: tj was posting this at the same time.

so would, A: not impacting the ceiling or B: checking the valve after you impact the ceiling

Shouldn't that be done no matter whats on that post?

Obviously this applies. I have not experienced a roll off, but know some that have, even with out impacting the ceiling. It happened in a low bedding area. It was impossible for the diver to realize that the knob was touching the ceiling at an angle just enough to roll the knob. He actually checked the knob after exiting the area and discovered it had rolled shut.

Of course we cannot all be perfect.

Wouldn't the lack of movement on the pressure gauge also give you a clue? (Except FW, of course, since his never move anyway )

Wouldn't help Russell either.

Don't look now Shirley, but I think you just answered your own question !!!!

Russell doesn't make contact with the cave! Have you gone mad, man?! If he has a roll-off, it wasn't accidental!

We're supposed to look at our pressure gauges?

Having the inflater on the right post allows you to shut it down while venting with the left hand if it sticks. Often, by the time you realize its stuck on, you've already got enough gas in the wing to start headin' up, so a vent and shutdown can solve both problems at once.

The 'third reg' thing is really low(est) on my list of reasons, but its an option not afforded by having it on the left post. Plus, when switching to an argon system, it keeps the DS inflater on the same side in both configurations.

As for not knowing the right post is shut down because of a lack of feedback, I find this to be a real non-issue. The move is to just check your valves (all of them) if you impact the ceiling (or come real close). I've had partial roll offs after passing through some areas, and I just check them. Relying on a non-working inflater to let you know that the post is off seems like less than best practice, to me.
