Anyone know more about this new ccr? Someone who tried it?

This statement (from their site) boosts my confidence:

The final version Pelagian DCCCR prototype was extensively test dived for four months before production started. To those of you who pre-ordered even before seeing any pictures: Thank's for the confidence and happy diving!

Plenty of people have asked me about an o-t-s KISS ... I guess that's pretty much the idea here.

- one pO2 display short, maybe ...

- the lungs look pretty good, unless you want to sidemount bailout ...
they look like neoprene ... bouyant?
- where do they add dil?
- building in Thailand should keep production cost low
- four months of testing ... how many units? ... not really much ...

They offer training for that thing as well as the IDA, not sanctioned, but a nice touch.

CLs curving back under the arms seems a very sound idea for wob, but as you say I wonder how it feels with sling tanks.

I am a big fan of the needle valve on the manual CCR allowing you to do away with the non-compensated 1st and dive beyond its max depth, but it is inherently less simple and safe and requires better understanding, more attention and (a bit) more adjustment. I am happy to dive this myself, but I don't think I would be brave enough to sell it to others with the legal worries that might follow.

Shame there is not more info/teardown pictures on the website.

Yer, but whats the point here, they have a 100m recommended depth limit, the same as most people get from a Std Kiss with non compensated 1st stage, so while the idea is sound it offers no advatage in this unit.

well Matt the only adantage as i see it is that you do not need to adjust the flowrate before a deep dive. You do not realy want to set the flow to 11BAR all the time on the classic.
But then again, the time it takes to adjust the flow is not that big advantage over the complications of using a needle valve...

just my ppO2

Oh really? why?

Coming back to the pelagian, I didnt see water dumps? Presumably they're easily added on the OTS lungs....

Also, more interestingly, I see no reference to scrubber capacity other than the usual x hours posted with no reference to a standard/test regime

Frankly, this is the one thing that REALLY irritates me in the diving industry, I've got an ounce of intelligence so would like to see the real data please, mr vendor

Why not ?

Mine was at 12+ bar the whole time except for the first few months since the smaller orifice wasn't available then...

2 good reasons:
1) you want to dive a CCR, not a SCR,
2) see 1)

But seriously ...

It wastes gas, having to regularly bring the loop back to minimum
(or, worse, adjust your BC, and then later still vent the loop, etc).

For new Rebreather folks, this also complicates mastering buoyancy control.

If you're taking it way deep (beyond Mfr recommendations

) ...
I can see the operational point, but not for everyday, normal use.

Dan, this depends on your personal O2 consumption. The reason Jonny is getting questions is because he's suggesting a different IP at different depths.... therein lies the confusion....
