From a "techreational Diver" - The thing I am having a hard time dealing with is "accidental deco". SITUATIONAL AWARENESS.... thats more important than anything!
Now, quite honestly, if you are leaving the bottom with a few minutes of NDL time remaining, or, even into a very light DECO obligation, it is likely to clear on the ascent (just please understand what the "Magic Bracelet" is telling you). I'd also add that if you have thirds for gas reserves, or utilized a RB calculation, you are more than likely going to be okay to handle the potential of a light DECO obligation..... it just gets "messy" if something else happens....
Now, I am also right now doing an Intro-2-Tech to get my head around this more, and will likely be stepping it up to Adv. Nitrox and DECO procedures as a next step (or whatever gets me to that).
