A friend of mine used an off the shelf second stage for his ADV on his modified Azimuth (KISS) unit. He machined a plug for the exhaust valve and a fitting for the mouthpiece end which plugs into the Azimuth lung. It's been working flawlessly for about three years now since he installed it. I can probably get him to send a few photos if you're interested.

Cheers,
Al.

Hi,
as I'm self thinking about an adv for my azi I would be very interested on seeing some pictures of that modification, if possible.
thanks

The Prism the ADV is for most parts a schrader valve in the counter lung.

This is a copy of the Mark-15 system. Not surprising as the Prism takes many of the Mark-15 engineering features into it's design.

Any old diaphragm second stage with the exhaust valve blanked can be used as an ADV. The above suggestions are all sensible ones. Gerstl Ossi, who made the one above, gets a gold medal. Wonderful work (as usual)! In fact, this deserves the coveted "Diver Dave Seal of Approval"...

For manufacture of rebreather and components nicer than factory! Well done.

The Ray dose device is the easy solution as it goes into a P-Port. Otherswise making one out of a second stage is the way to go.

Thanks for all the suggestions, I think I am leaning toward making my own.

I have an older sherwood magnum, so I can use the innards from the second stage, theres a good plastics store near by with a lot of ABS in the scrape bin and I have a mill and lathe so I might as well go for it.

Does any one see a problem with using the purge action from the second stage as the manual diluent add? Do you think there would be a bigger chance for it to free flow? But I think that would be an easy way to kill two birds with one stone.

Hi,

what about the setting of the valve? you would have to set the valve harder as the normal setting, wouldn't you? If yes, is it a trial and error item or can you give me a pressure, that I can set? (I think, I could measure it with the standard gauge of the azi)

Before using the Drager Dosage units we used to buy the Scubapro 109's for cheap. They have an adjustment nob to help control free-flow.

Here is a link to one on ebay if you want to know what they look like.

It is trial and error especially depending on where you put it. Better to locate it up high on your counterlungs rather than low to help with free-flowing.

Thanks Dave for the compliments. But it's also merit of rebreatherworld, where we find a lot of ideas and my brother who help me a lot and who is on the way to finish the HUD for the 2 breathers.

What would be a good second stage model to remove the valve assembly from? Preferably one that doesn't require the housing to hold things togeather. Something that you could remove the inner lever part and the outer hose connection/valve seat part from the housing and just screw the two parts back togeather.
