Diver one of sixteen to die using high-tech gear

[DRE]

A comparison of the 200 for 20 on OC:

I use GUE's D-plan (the Palm version of Decoplanner) to calculate my profiles, Low GF: 20 High GF: 80.

Bottom gas: 18/45 (pO2 of 1.3, END of 95ft)
Deco gasses EAN 50 and O2

D-plan includes descent time into the profile, so I'll be leaving the bottom at 20 instead of 24.

fsw min run mix pO2
200 20 20 18/45 1.3
110 1 23 18/45 0.8
100 1 24 18/45 0.7
90 2 26 18/45 0.7
80 2 28 18/45 0.6
70 3 31 50% 1.6
60 1 32 50% 1.4
50 1 33 50% 1.1
40 4 37 50% 1.0
30 5 42 50% 1.0
20 19 61 O2 1.6


As you can see this schedule gets me out of the water as quickly as the constant Po2 profiles of the Inspiration. The only benefit the CCR has over OC is that the volume of gas used (not necessarily gas carried, as Divermole pointed out in his previous postings using the 7L/46cf tanks plus bailout and the size of the rebreather gives you about the same profile as OC) is a lot smaller in case nothing goes wrong. To do this dive safely on OC in terms of bailout gas you need a minimum of double AL80's with 2 AL 30's for deco gas.
