        Reply to:   Rebreather toys...
On of the things that I wonder about the advent of rebreathers (and I admit
that _I_ want a rebreather too) is the question of, "I'm at 100 feet and, for
some reason, my unit stops working.  My buddy, being another toy afficiando
like myself, also has a rebreather."  Now comes the million dollar question:

Can one rebreather sustain two divers for the ascent and decompression hang?? 
How is buddy breathing off of one of those?  The unit has to work not quite
twice as well as required for one diver.

Anyone have any thoughts on this? Sure, you can always have a pony bottle down
with you, but from what I saw of CIS-Lunar, the unit is heavy enough without
adding an additional pony bottle.

Now, I know that the rebreathers have an additional air/O2/something bottle
because there's no rebreather that doesn't have some loss, but is that bottle
sufficient?

I'll get around to it today
  -- for sufficiently large values of "today".
