To clarify that "new rebreather" comment I made, it is not new in the
sense of new concept, it is a military version of the same one that is
designed for a specific type of dive "mission". It also happens to fit
for what I am doing, which is only using the thing deep. It has a high
fixed ratio, so to use it for normal diving you would have several gases
just to do a regular dive ( to get both down and up).

  I breathed open circuit and then switched to it at depth, and did not
deco on it. I just wanted to see its gas milage and how well it held its
PPO2 and what the FiO2 was at diferent depths, so I ran it with oxygen
sensors and a wrist guage readout. Now I know why I don't dive CCR's -
every time that thing changes it distracts me from what I am doing, and
when it does not change I do not believe it. JJ also had a readout for
my machine so I ended up ignoring it and he watched it.

 BTW, "testing" rebreathers by me is nothing new or radical, I have
lived through all of them, and when Jarrod Jablonski is your dive
partner, it makes it easy. Anyway, we are tyring to see at what point in
the ratio the inspired gas no longer closely matches the supplied gas.
Gavin calculated that, and it came out exactly as he predicted at depth,
as is usual when dealing with Gavin, another thing that gives me
confidence when "testing".

 We also needed to test the towing capability of the bigger scooters,
the speed of them, the lights, and so forth, and the combination of
everything at once. It was business as usual, with more range in the
cards. JJ and I then just switched out to open circuit to get some
practice doing that for once, and did half the bottom time and all the
deco that way. Interstingly , one dive in that place is like doing ten
scuba dives as far as tuning you back up due to the duration of the in
water time. I had not bveen diving at all for the last few months due to
training.

 Also, what we are realy doing is finguing out what works best in the
course of exploration there so we can take that show on the road to
Downstream Turner Sink, where it really gets serious.
