Are you sure ? It's been debated at lengths already...
Now, to answer Stephane's specific point above: the SCR and the mCCR are both certified when coming out of the factory. But if you get a SCR, then separately buy the transformation kit and convert it to a CCR, you end up with a machine that is technically not certified anymore, hence the warning in the kit, to force you to go back through your local distributor to perform the conversion. At least, that's the only theory I can think of.
I concur, and as I have no intent to get down to 11 bars, that's why I've gotten a submatix mCCR.
All certification problems are interresting.
a certification is normaly a definition of the minimal criteria that a machine must meet to provide a minimal safety.
if the machine is certified to 100m and his users state they would not dive it deeper then 50 m it would be interrested to know why ?
it can mean that the minimal criteria are not severe enough to provide us with a good safety.
it can mean that this rebreather or others have not meet the critéria and that certain certification company are not serious or more liberal then the other ones...
all those certification problems have always puzzled me.
I remember years ago when the dolphin and the buddy were EC approved before the norma was issue (((-:
in my opinion it is always interresting to know how to evaluated rebreathers, what is a good rebreather.
I always ask myself this question in the same way that you are doing all the time.
as we talk about many times I find my dolphin based dolphin a little bit hard to breathe where my buddy who dives the same finds it ok.
I suspect my sensor holder to harder the wob and this is the reason why I am machining a custom one to try to find out if it is ok.
when one buys a machine one have a choice to make, this choice is really difficult because the diver usualy does not try different machines to have an idea.
so what is the choice criterias ?
forum discussions, advice from friends, reputation of a machine ?
it would be fine to be able to read the result reports of the EC tests of the machines that passed the test.
common minimum standard shoulb be issued and the tests result should be published .
the debate will end when all of that be tranparent.
