Dry Suit inflator hoses - Which 1st Stage for which hose ?

[rhwestfall]

Squeeze is the last thing I'm worried about when an air share situation is happening... Getting out of the situation is...

The reg in my mouth (bungied octo) and my lpi for my wing are in my control as to when they are used (avoiding the same time).

I don't know when the guy on my primary is going to breathe.

Any cold-rated first stage should be able to handle two stressed-out divers with an elevated breathing rate sharing air without free-flowing. I think both the EN250 and US Navy specs call for 62.5 litres/min (2.2 cuft/min) in cold water at 6 ATA. Worrying about a short squirt into the wing or suit at the same time as a normal breath seems ... unnecessary.

What I do know is; I have dived 3 of the Great Lakes with a single 80 and dry suit and doubles with dry suit, Ice dived in 18 degree surface and 34 degree water, all of the quarries in Indiana and Ohio to depth all 12 months of the year, sharing gas as both donor and receiver in both configurations with dry suit, with BC on right and dry suit on left and never had any issues with free flow due to freezing 1st stage. I have dived these diaphragm and piston. Which in my opinion a 1st stage set to higher the spec'ed IP or one with creep is where someone would most likely have a problem.

However, we were on Huron one time (back around 2007 and don't remember the wreck), when every Apex (at least 2 or 3} had free flow issues.

But... that's not how DIR rig it. Will have the Hog police on you!

The most important thing is to have the wing & suit separated.

BTW if you've got a separate suit inflate bottle, this will be rigged (ass-u-me DIR) on the LHS.

Hmmm. I read an article that was recently linked in a SB post in which William "Hogarth" Main states that he, himself, does NOT cross his inflator hoses, IIRC.

Maybe someone will find that post before I do...

I saw front zip drysuit should not have inflator hose cross the zipper. DUI CF200 I would not put on the left side.
The newer suit inflator can be rotated around, which I thought was neat. My inflator hose is long enough that it makes a slight curve near connecting to inflator. So it crosses zipper. It would cross the zipper on the right side by default. Maybe a different LP port or shorter inflator hose would eliminate the hose curvature near the zipper.

That is true, because he prioritizes early warning of a left-post rolloff in a cave environment. Nor does he typically have a suit inflator hose at all ( because he uses a wetsuit). I have no idea what configuration he would use in an OW+drysuit scenario.

I was using a Duracell, Ok I will go and get some Energizer Ultimates,

Cheers

I had the same behavior last weekend, just that it died under water. No big deal, because I had a backup which shortly before the other died also showed a battery warning. Both computers worked again back home. My fault, I should have changed batteries when they hit 1.2 V.

Best wishes Jens

From first principles: the wing and drysuit inflators MUST be connected to different sides: if you turn off your longhose, then you've lost the wing but you've got your drysuit and vice-versa.
