Swivel recall/time to change

[beanojones]

Which one do you put the swivel on? The necklace reg, or the hogathian reg?

I was talking about the swivel on the Hogarthian reg in my case.

Yes, the elbow goes on the primary regulator (what you are calling the hogarthian) with the 40" hose, where the hose attaches to the second stage (sorry for the terrible picture). It routes under your right arm.

Not to split hairs, but it if was really part of a hogarthian system, the primary would be on a 7' or 5' hose, wrapped around your body and behind your neck. See the GUE link above for examples. Hogarthian describes an entire gear configuration, the regulators are just a part of that.

The backup (necklaced) reg always goes on a 22" hose and doesn't need any elbow, swivel, etc. It stays under your chin out of the way until you need it.

IMHO, the answer here is a case in point: Just another failure point. Eliminate it and use a stinkin', normal reg and hose, like 99% of divers out there. They manage apparently, so it can't be that bad.

The 'under your arm and around the neck one' was where I used the swivel. Hogarthian only refers to that sort of routing, right? I use the hose looped around the neck (not the necklace thingie) for all dives.

Since you seem up on the DIR stuff, why are they against Air2s? (If not here, where on this board should this sort of question be asked?)

You can make a case for that, but some people don't care for the big hose loops. Yes, the elbows are another failure point, but they are another failure point identical to the existing failure point that already exist in virtually all regulators today. If you can hold your regulator hose out in front of you and pivot the regulator up and down, that regulator has the exact same captured o-ring design that an elbow uses to pivot left and right. Different than the 360° swivels.

Back to beano, DIR would be the 7' long hose routed down your right side, under your can light across your body over the left shoulder, behind your neck and to your mouth; with the bungeed backup. No elbows or swivels for DIR dives. Even the 5' hose is frowned on by some DIR types, though for a strictly recreational rig with no can light it can work very well (and even works for those who don't use a BP/W).

Not to be a nitpicker (much) but is that right? I haven't dived/owned any regs that have a swivel or elbow built in/supplied a standard, I thought they were optional in the majority

There are two different kind of swivels mentioned in this thread.

The 360 swivels are one animal. I won't use those, for structural reasons (threads are undone by normal action and the strength of the threads is the only thing keeping together).

The SP 120 and the DR 90 swivels are just the same kind of swivel the all second stages have, just an extra one. The same swivel that is right where the hose attaches to the second stage.

Ah, I understand now - the rotational joint on the second stage

Re your Air2 question, you'll find several threads here with both lovers and haters

I am wondering about it from DIR perspective. Do the threads you mentioned talk about it from that perspective?

 

[Tortuga68]

Well, firstly I should say that while I use a Hogarthian rig and subscribe to a lot of DIR practices, I'm not a dedicated DIR diver per se

But without wanting to put words in anyone's mouth, from a DIR perspective, Air2 is a nono

DIR theory is to have your primary on a 5/7' hose (singles/doubles) with your secondary bungee'd under your chin on a ~22" hose; that's the rig I use, and I wouldn't do it any different

Plus DIR is BP/W, and again Air2 doesn't really fit there

So, Air2 doesn't suit DIR philosophy, hence it's not DIR

You can look in the DIR forum for further info, just be aware that it isn't for questions about why DIR, only how

HTH
