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

Rebreathers, goals of 200', 40cf bottles wanted for deco gases, upgrading a compressor to handle trimix... Sounds like tech diving to me.Nwbrewer wrote:No dog in this fight, but the GEM is a Recreational rebreather. (as John pointed out)Penopolypants wrote:Moved to the tech diving forum. Carry on!

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.

Well you already have a 30cf bottle which is pretty nifty for O2 on <200ft dives.Jeff Pack wrote:Deco gas(s)CaptnJack wrote:Why would you use a 40 with the GEM?Jeff Pack wrote:thx Dusty had noticed that, but for now I need a couple of 40's.Dusty2 wrote:Before you go crazy????? Hmmmm?

I dunno you might want to get that nitrox cert and put in some hours on the GEM before thinking about deco gases...
