I thought I heard somewhere that the GEM was a recreational rebreather....:grin:

Rebreathers, goals of 200', 40cf bottles wanted for deco gases, upgrading a compressor to handle trimix... Sounds like tech diving to me.

The 8:1 mouthpiece was available from the original designer (in Missouri I think) before Jetsam bought the design/rights to the GEM. Its been to 200ft before there's just no agency/cert program to get there right now. Although you don't need an 8:1 mouthpiece to take it to 200ft anyway.

That said, I think you ought to look really hard at how the ppO2 drop (on any pSCR) just destroys your deco time (in a bad way) before thinking about using a GEM in our cold and current sensitive waters. And how you might choose to match a profile with a buddy, either an OC buddy or a CCR buddy since nobody else around here is diving a pSCR to 200ft.

Carry on, good luck and all that jazz

I believe you are referring to Mike Young in Arkansas? If so, I've been speaking with him already.

After my class, I need to send my unit to him for some upgrades.

And yes, looking at gas planning, I wouldnt need the 8:1 to hit 200ft, but I'd rather have the 8:1 for buffer, etc before I'd do that. My gas switchblock wont be here for about month anyways, but I'm a long ways off before all of this, I'm just planning ahead. I've actually got a line (I wont mention his name) on a guy that might be able to get me some GEM technical training. But I wont pursue that until I get some time on the unit of course.

Like Laura said, Crawl, walk, run.

There's alot to learn, and alot to relearn again.

thx Dusty had noticed that, but for now I need a couple of 40's.
Why would you use a 40 with the GEM?
Deco gas(s)
Well you already have a 30cf bottle which is pretty nifty for O2 on <200ft dives.
I dunno you might want to get that nitrox cert and put in some hours on the GEM before thinking about deco gases...
