Twin-set Reg Configuration

[julian.carroll]

Hi guys,

This weekend I dived independent twin 7s and, while I liked them, I am wondering how people combat the problem of the left reg getting tangled in the wing inflator. I use my wing for buoyancy and when breathing from the left post, it is quite hard to dump air because the inflator gets tangled with the reg hose. My girlfriend solves the problem by routing both regs over her right shoulder. What do other people do? I dive with trainees, so Hogarthian long hose isn't an option.

Thanks,

Julian

Imagine you are diving with a single and a very big pony fixed on your right
and the routings make a lot more sense.

I use 3 regs with a standard warm-water rig on the left post. That puts
an occi in the same place as where a student expects it to be. The primary
comes from the left post, behind the head and feeds as normal. This is the
one to bungy or you can use a press clip on the shoulder. The right post has
your primary and its also got the drysuit feed on it along with a single spg.
Both SPG's go under shoulder straps so the only hose that can be grabbed
and is free is the occi on the left.

In use you suck 50 bar on rt, then swap to bungy, do 50 bar etc.
That means the left cylinder will always have 50 bar more in it and thats
the one with the yellow occi attached. In a fubar the hyper student who
has an elevated Sac has the most gas, but ............... that doesnt
mean in a jam you dont also have access to it via the bungied reg.

This system is very simple, clear and works very well with students
as the occo mirrors all stndard training rigs.

It also has the bonus of not having to mess with your regs on your hols.
The left-post reg combo is a bog standard warm-water setup :D

(you can have a long hose and not hog rig it, or just hog rig it sometimes)

how long is your main hose ? , what ever length you run you can run them both over the right shoulder.

when teaching trainees, my "long hose" (5ft) which is normally bungied into my wing, becomes my octopus.

If you are going to teach and dive, sometimes there has to be a compromise with kit.
One of my friends has has an octopus length hose and a normal one and has no problem with running both on the right (necklaces the octopus with trainees and the nectlaces the short one when diving with me)

Hi Terry,

This is what my girlfriend does and like you say, the octopus is in the normal place so students don't have to worry about it. This config also means 3 right hand regs so no need to change any to left hand. Overall, sounds like it is perfect -- was just wondering if I had missed something since I haven't seen anybody dive that configuration before. Thanks!

Here's what I do with my twinset regs and it works a treat. Normally I have both regs over the right shoulder, necklace the left post and breathe the right post (2.1m hose).

If I am teaching then I take the necklace off and breathe that from the left post as my main reg. The right post long hose feeds behind my neck and is bungeed to the left cylinder. Reg then clipped off on my left hip, just where trainees expect to find it.

Woz, are you talking about manifolded twins there?

relative newby ,but, would have thought it made sense when teaching to stick to identical kit that the students are using. I.E single bottle with same 2nd stage and occi config. And save your twin set for your own pleasure dives. But i,m probably wrong.

Depends what you are teaching.

A single cylinder on OD would be ok, but there comes a time, when
redundancy needs to be considered as you go deeper/longer and
thats when pony/twins come in.


I'll agree with you on the indentical kit bit. to me its a
flawed practice to adapt existing twin rig for teaching.

I've never sunscribed to the logic that says you re-configure a twin rig
to comply with occi use. Not only does that mess up conditioned responses
the long-hose "fudge" rig is often black hosed and black faced. Not
exactly an easy thing to spot for a newbie trained to see yellow.

I prefer the simple approach of leaving the twin rig EXACTLY as it is and just
add a single yellow occi to one of those 2 free ports you are not using on
the left post.

Diving = standard rig, training add occi. Easy ;)

they has advantages, but means I do need a seperate set of kit for this.
And training happens during "diving trips" so if my kit its good enough for adhoc kit then its ok for proper training.
Also I want my second cylinder (pony or twin) when every I dive and I'm not compromising that !
A last point, I am unlikely to get the same as the student as some have left shoulder octo, some right. Some have wings, some have ponies, and some have twins...

We dont get that problem :p

Everybody, students and Instructors alike run a standard occi left rig until
Sport Diver.

After that it's open season :D
