Manual gas addition on rear mounted lungs

colinicky · 23rd April 2006, 23:59

I have been in contact with John a.k.a narked @ 90 to sort out another way for manual addition of Dil or O2 for rear mounted counterlungs .I know that Paul Channing has a very good & neat system on his conversion but I also know there are some out there who still reach behind to find the original buttons .
My idea which John has said will work involves using the lp hose in a STANDARD position ie over the shoulder to the front with the original AP addition button fitted ,John can (hopefully ) make an adapter to fit to this that will take another lp hose back over the shoulder to the bottom of the counter lung with another adaptor from John fitting to the counter lung .

This will give you a manual add valve coming over each shoulder following the harness straps to a point on your chest that is comfy for you .No stretching behind to reach buttons .
I am going to see Paul & try his conversion in June but I think due to back & neck problems I may struggle to reach the ADV comfortably (I struggle on a standard unit ) This is what has led me to think of this .
but as with everything the more interested parties the cheaper it becomes .
So any interest or comments would be appreciated

Take a look at the bottom of the page on this link....

I this is a nice clean way to handle the "add" part and use John's adaptor back to the lungs.

Another approach would be to get the "gas add" assembly from an Azimuth and plumb it in.

This is about the same neatness level as I'm looking at with John.When I can work out how to get pictures from an email attachment toi the forum i will post a picture of all the parts .this modification will not involve cuting or bonding ,it will slot straight in with no modification needed .at least thats how it looks at present

Not such a new idea. I did this on my FGG conversion years ago. It worked quite well, except for the occasional freeflow in very cold water.
Take a look at the controls coming over the shoulders here:

We developed an inline adapter which allows a second feed on the Insp manual adds as a matter of fact Brent (Diveworld) posted a pic of it on his site, If he's out and about he could post it again. We have them in stock and ready to go.

So are you aiming to end up with a setup a bit like the Boris, with an injector hanging over each shoulder instead of a whole lung?

If this is the case, surely something like a BCD LP inflator hose hanging over each shoulder would work - then you just need an adapter (or bodge it) to thread the end of a wing-inflate-corrugated-hose-elbow to the AP manual injector plate?

Or as Mark mentioned, a addition block like the Azimuth would be really neat, as this has 2 gasses plumbed into it (and one feed out), and a (interlocked) switch that allows you to choose which of the feeds the button will work on.

Simon basically yes it would end up like a boris inflation .
I was going to use the feed hoses that are the standard manual addition hoses on the ybod with the Ap manual inject button then use an adapter to connect an lp hose to the counterlungs .

have never seen an Azimuth block so am in the dark on that one .

Here is a nice explination of the block etc...

So this is a constant flow but with adjustment .
can you turn it down to nothing ?
And were can you buy them from ?

So thinking out loud here....

Could you use an Azzy valve inplace of a KISS valve. Have one source connected to the regular uncompensated first stage, and have the alernate source connected to small o2 tank with a compensated first stage, and in line flow restrictor.
