Is that 1.6 ppo2 at 21 meters on that profile??
I guess its just for a few seconds though.....

Not done an deco diving but this is a free app on the iTouch or Mac for those who don't have a PC and can therefore not use V Planner
42m/20mins on Air and using EANx50 as deco gas
42m/20mins pO2 1.09
32m/1min pO2 0.88 RT 21mins
22m/1min pO2 0.67 RT 22mins
STOP 18m/1min EANx50 pO2 1.39 RT 23mins
STOP 15m/1min EANx50 pO2 1.25 RT 24mins
STOP 12m/1min EANx50 pO2 1.10 RT 25mins
STOP 9m/1min EANx50 pO2 0.95 RT 26mins
STOP 6m/3mins EANx50 pO2 0.8 RT 29mins
STOP 3m/5mins EANx50 pO2 0.65 RT 34mins
CNS: 12.4% OTU's 27
Air 2217.6l
EANx 50 413.0l
SAC Rate was set to 20l/min
Great free App for the iTouch and does He too. Everything cn be changed to suit yourself.
If you want your last stop to be set at 6m then final stop is
STOP 6m/9mins EANx 50 pO2 0.80
CNS: 12.82% OTU's 29

Air is used on the 21mtr stop and even if 50% was used it would be 1.55 pp02.......so no problem
Deco gas is used at 18 mtr stop and shallower and I stay away from 3mtr stops harder to keep stop accuracy on open ocean dives, due to swell
Resting phase of the dive..deco 1.6 ppo2
Working phase of the dive ..bottom mix 1.4 ppo2
set in stone........cheers:D

On that do you swap mix at 21meters, as soon as you arrive at that depth?

Very sensible, thats what I usually do :)
Am looking forwards to doing some training dives building up for the subs :)

Cool, thanks a lot :)
Enjoyed my dive today, although it was a little eventful - more before I got in rather than during! Twisted my ankle this morning when I splattted myself on the ground. Ankle wasn't feeling too bad until I was putting my fins on, when it gave way under me. Huge 'crack' was heard and I thought I had broken it. A few minutes later I was able to get into the water with a hobble, with GG carrying my kit down for me.
Once in water, realised the dump valve on my suit was letting in water, but it was way too much effort to get out so I did the dive anyway - could only fin with one foot, but was mostly going down anyway!
Had 15 mnutes bottom time on the wreck at Furnace (max depth 43m) then planned stops and ascents of 20 mins with an extra 5 mins deco for safety. Bent my computer as it doesn't do gas switching - it's still showing SOS.
Getting out up the slope beside the pier was not easy and thanks to all the guys for carrying my kit - I could barely put any weight on my ankle. I now can't walk on it at all - not so good. :(
And thanks for carrying it all back to the car - much appreciated. My left side was soaked from the leak - I pulled the cuff seal and all this water came out!
Anyway, cheers everyone, good dive and thanks for all the help.

Did you get your ankle checked out Claire. You might have damaged a ligament which can be as bad if not worse than a fracture. Hope it is ok. Cheers DG x

Hope you are resting it then:rolleyes: Sit with your foot up as much as possible. No galavanting about dive sites till it feels better:rolleyes::D
We had a great dive too,Claire's lot did the wee wreck at 43M and me and steven did our final trimix dive for the course to 50M but my bouyancy was crap as i hit 51M :o
We set up Ians deco station (which is brilliant :D) and we all ended meeting back up to complete our deco at the same time.
Nice day out in good company,certainly beats crimbo shopping :)
