The deco is done on the breather and you only take Rebreather-decotanks =
for
the "far" deco.
A 14cuft O2lowpressure  is for example all the o2 you need.
W hat in case of a rebreather failure ? You just call the dive and =

to the entrance where of course there is also
open-circuit bailout-gas. You only have to have a deco-schedule for =
that
longer bottom-time and put that into account for the amount of
deco gas.
The diving after the first sump is mostly done on a 50/25 and requires =
only
slow ascends and no decogases !=20

Open Circuit it IS a nightmare.

On the other hand it is strange, a few years ago this would have been =
the
end of the line and a major exploration.
After the Doux de Coly-dive Reinhard said to Herv=E9: " You are up for =
a
chill-out-dive" ?
And they came in the morning and just did it and were out at night.
I think that is pretty cool. Too bad i had ear-problems (which is also =
bad
for sump-diving)
