Saturation

Red Sea Explorer · March 12th, 2006, 08:37 AM

We always talk about the minimum and the maximum and accordingly decide our deep stops and our deco.
Most of us on this list are more or less diving closer to our minimum than our max.

But what will it look like as we approach the Max.

We all say (and claim to know) that 150 mintues at any depth is saturation.
So what is the deco for that?

150 minutes at 30 meters what is the profile?

Why stop at 27m? You won't be off gasing there. Also IMHO you are loading up on the 18m and 15m stops and then rushing the 12 and 9

If anyone out there is doing these dives please shed some light on the matter.

If you are saturated, then any acent especially a whole 3 meters would get you off-gassing.
So don't cut off the 27meter stop.

Stop the intellectual masturbation.

Start with AF's answer on the G list. If 30 min is the top on O2, then you need another 15-20 on the way to 6m. Would someone try this profile on DP or the RGBM programs so we get total numbers for softwarre benchmarks? You would be surprized what the cave 2 guys were doing at 30m. Like 1 hour and deco out for 15 min on O2, so the 30 min that AF threw on the G list is the benchmark to start with.
