Wanna stay down longgerrr

[Swedinsidemount]

i saw that I first thought it he may be doing the best mix or using 40%

Exactly, in order to stay down at the depths i want to achieve i have to use a lower mix like EAN26 or 27.....

I don't know of any viable commercially available SCR rebreathers any more. Can anyone name one?

you dont need the mix to stay down unless it is for controlling ndl in order to max out your twinset capacity.

i saw that I first thought it he may be doing the best mix or using 40% for shallower dives

I did the math once, even using the conservative NOAA 24 hour rolling window, you have to be diving pretty aggressively, like 5 dives a day pushing max depth (based on 1.4 max) and max NDL each dive for two or more days, to be CNS limited. That is why I was confused.

But now that he clarified he means being limited by the MOD.

I went through that when I started nitrox and always used 40% because the dives were all under 80 ft. My dive computer and aeris elite 3 would call out cns AS THE REASON FOR LIMITING REMAINING TIME. BOY THAT GOES WAY BACK 20 YEARS.

Occasionally people buy and dive RB80s and related clones from other European manufacturers like the Hyperion or the tres Presidentes. Although my supposition is that they are just buying and selling amongst themselves and few brand new units are being manufactured. but if you wanted a new one you could probably find one. It's just there's so little to break or wear out, pSCR units from the 1990s are still in use and being dove. When one diver decides to hang up the long range cave exploration fins another ends up buying the unit used and it carries on.

Nobody buys this unit, the only reason its available at all is because it shares 95% of its parts with the mCCR Kiss Sidekick. It's also crazy flood prone.

Whatever you do don't buy an SCR. I've never known a single person to get one that didn't quickly abandon it, or move to a CCR. They are very unsatisfying with all the hassle of a CCR and almost none of it's advantages.

Hi it’s me, an scr diver that hasn’t abandoned it for ccr
