my new set up

[paulo]

Here's a look at my first attempt at setting up a twinset. It is by no means perfect and I would be the first to admit that. I haven't had it in the water yet (getting a visual done on the cylinders tomorrow and nearly clear of this fucking chest infection).

What I have is: Faber 12s with agir brokk manifold and bands


Ali backplate with a continuous harness fitted to some model of a Halcyon wing, I have no idea what the specs of this wing are but I would appreciate it if anyone can shed some light



SP mk17 with a R395 (RH post) fitted to a 2m long hose and drysuit hose & SP mk10 with a R190 (LH post) BC inflate and my SPG.

Shorter inflator hose maybe but looks great!! Best of luck with it!
Hope the bottles pass the VIP :-)

[David Mellon]

defo shorten the inflator hose as the current lent is a potental snag...
I like the old halcyon wing very cool

Any idea what one it is? Cant find anything out about it, no tags or anything anywhere, not even on the inside

[David Mellon]

the current explorer model is the same as yours but I dont think it was called the explorer when yours was made...

, Dave, not DIR!

You're supposed to run the wing from the right post and the suit from the left post or suit bottle!



paulo, never mind that, I'm doing it that way too.

Cheers,

I might be wrong but I dont think Paul wants his gear gue\dir just what ever way suits him

hi paulo ,
a few pointers hope they help

if you change/swap your regs to the other post you wont have to shorten your hose . make sure your primary inflator (wing ) and main reg are off the same post . and your secondary reg and inflator (suit) are off the same post .

I put my main reg and inflator off my right post and secondary reg and inflator off my l post . routing is tidyer that way .

on deeper dives i run my suit inflation off my left stage cylinder (usually 50%) as its warmer (and not as expensive as helium)

hope this helps

I've just put my new setup together and have drysuit feed, primary reg and secondary (disconnected) wing bladder off right post; and secondary reg, primary wing off left post. Don't mean to be dense, but what's reason for switching my wing feeds around? Hose routing seems ok, and it's a Custom Divers TCW. Thanks for input.

Steve - the 50% as inflation gas would help prevent isobaric counter diffusion problems.

Paulo - routing all primary off primary post ensures if you have primary failure you know to switch all to backup.

Routing and other safety considerations in tec diving would be covered in any tec course.

Just out of curiosity Dec, I thought IBCD was a concern for breathing gas mixes and avoidance of a vestibular bend. I know helium is a no-no for suit inflation but thought air /argon was preferable for heat not IBCD issues. Are you suggesting using 50% over air/argon or are divers presenting with skin bends from inflation mixes with a higher nitrogen content (excluding helium)?

Just curious,

Cheers, Aaron

IBCD is just helium so no helium in suits!

It's in chapter 1 of DSAT Trimix manual. No mention of IBCD in tdi normoxic manuals!

Thanks

I was about to ask who in their right mind would put a helium rich trimix in their suit in Irish waters and done a deep dive with a lot of decompression but I suppose I'm sure somebody somewhere has done it...

I've read a lot of "internet knowledge" about IBCD - has anyone ever seen a case of it or spoken to anyone who has witnessed it first hand? Actually I have.....but only one and that was from gas switching diluents on ascent after very deep dives. Well known case.

IBCD a worry at normoxic depths? I don't think so.....

Just my inexperienced, non-scientific and totally unqualified 2c.

Even if IBCD were a real concern (and I believe it isn't) the advice to use a rich nitrox as a suit gas is a mistake. I really hope lads don't start using their deco gas as a way of countering this IBCD bogeyman. I couldn't think of much worse than wandering around a boat after a dive wearing a rubber suit full of oxygen. Cup of tea and a ciggie boss? Whooomp! 

Just use air. Clamp on a 1-3ltr cyl as a suit inflate bottle if you have to.
