Isolate and Shutdown routines

[Wreckie]

Inverted twins on independant reg systems,easly to shut down all at the drop of a wrist. I carry a small cylinder to wing & suit inflate.

rule of thirds dear chap,,,,:cool: but hard to use all this new hi-tek stuff at the mo as i'm only small......

Been thinking more and more seriously about the inverted set up, AFAIUI the only thing I need to do now is get longer reg hoses - what length hoses are you using Wreckie?
And are there any other current "invert" users on the forum?

Example - your spg goes fizz bang and disappears off into the blue. In this case as you know the guage is run by the primary post, all you need do is shut that, switch to backup and go....

The SPG is fed from the left side or secondary post, as is the backup reg and drybag inflation (If not using an Argon bottle that is).. You've been at Emmas cooking sherry again haven't cha Drifty me ol'cock!  Also you'll notice that I already agree that in a real situation I'd would go for the isolation first, but!

I was talking of practise routines.. you know, like turn off primary valve, breath down reg, move to backup reg, open primary valve, close isolation valve, open isolation valve, close secondary valve, breath down reg, move to primary reg, open secondary valve...... check time taken etc..

There appears to be some variation in routines according to who you ask, I was just initially trying to get a handle on.. as the thread title say.. "Isolate and Shutdown routines" so that I can practise them in the wet, but things have moved on since I first asked the question months ago and I think I'll go with the GUE method described above..

Regards
Dave.

Mine wasn't :wink: We're not all of DIR config Mr. Willo

Not yet.... soon

I was talking of practise routines..

Practice for the worst case scenario me ol' duckie, that way when the widdle-inducing failure occurs you know you can cope with anything.... And if it's not all that bad you can shrug it off and be happy in ascending rather than thinking how much it costs to de-soil and undersuit.....

Davey, never figured you as George's whore..... :lol:

OK, Let's Rock People.....!!!

Bren is Winged-Twinned and ready to Sin....!!!

Just got back from La Hayhurst's gaff and, even if I say so miself, my new kit looks the Nads!! Just need to get my matching JetStream Regs (two) and DIN 1st-stages this week and collect my Turtles avec SS-fin-straps and the job, as they are indeed wont to say, c'est une good-un!! LARGE IT!!

The Halcyon 55lb Double-bladder Wing/Back-plate/back-DSMB-bag and webbing has been cut to fit and fits a treat....though I think Andy making me wear all this and just a nappy was a bit much!

Isolations and shuts-down Davey?? Get in the water and let's play!

Lucky bastard.......

Hello list,

I always used independs but maybe next year switch to manifold twins. So I am not talking trough experience, I read somewhere that you can only open the isolation manifold 1 turn as air will still migrate slowly and will be faster to close, this way it will take a couple of seconds to close iso 1 turn and at least save half gas. In a real situation I would go for isoolator first as if you close wrong side you would have lost a lot of gas...what you think?

Regards

Hey Wreckie,we're in a minoroty here y'know!I've gota twinvert set but it's stillin it's RN config so it's just got the 1 DIN on the manifold...rule of thirds again.I too can't really be arsed,just shut it down/turn it on and if you need repeat till in the dry bit.
Steve,Andy 2 tanx has been experimenting with his twinverts so he'll be handy to talk to.My old Man uses ex-police(twinverts) sets but on standard length hoses!!
Mail me if you want more on that.Right,hoses.If you go the independant route you'll probably need longer hoses for the DV's,try it first though as you may find they reach...sometimes.If not you've got a couple of options.Sherwood do long hoses as standard,as I beleive do a couple of others.See if these are suitable for using with your 1st/2nd stages,remember you can always use adapters if needed.Standard type hoses can be made up by SCUBA suppliers but they're usually priced accordingly.A betteroption is to find an industrial hose/hydraulic specialist in Yellow Pages etc and get them to make you up a set of Aeroquips or similar,just tell them the lenght you need and the working pressure.Get stainless fittings etc. too as some are alli.They usually cost about £20 tops.
HTH,Hobby.
