My Perdix is in high conservatism mode, GF 35/75. I did not complete my deco stop at 10 feet. This was the first time I went past NDL.
Below is my my dive profile. I don't understand the deco and GF data.
- Does the height of the red deco information correspond to the deco stop depth of 10 feet?
- My ending GF was 77%. What exactly does this mean?
- 10 foot deco stops are hard to hold in a drysuit. If I want a deeper stop, like 15-20 feet, should I switch the GF away from 35/75?
- How close to being in trouble was I?
I felt completely fine after the dive. Gas was EAN 32.
HI MolaSquared,
@rsingler answered you questions best above. If your dive count in your profile is accurate, you're still a reasonably new diver, and not having had any advanced training (and by advanced, I mean deco, not AOW), you don't know what you don't know. The other posters on this thread are not wrong, but they are also being a bit harsh.
They are not wrong - that is not a great dive profile. But instead of listening to them chastise you , it would be worth asking yourself, and more importantly answering honestly, some questions about this dive.
It is easy for newer divers, especially those used to relatively shallow diving, to forget about NDLs because they hardly ever hit them. This leads to poor (or no) planning. The question to ask yourself - did you plan this dive? At this depth? For this period of time? If so, did you follow the plan?
If you've never been into deco before, you may not have realised that your computer was telling you. Spend some time topside with your computer, and make sure you know how to understand what its telling you. And when you're on a dive, make sure to keep an eye on it, and heed what it's telling you. Unless you have planned to do staged deco (which you are not trained for, so you shouldn't be doing it), when your NDL is approaching 0, make sure you start your ascent.
All dives should include a safety stop. You did not perform one at all. Why not? Did you plan to? Did you forget? Were you not able to hold depth at 15' or 10'? Were you low on gas? Was there another emergency?
You need not respond to my post, but it would benefit you greatly if you could answer those questions honestly to yourself.
