Deco: Is it a big deal? Yes.
You are on a deep dive to something great like a wreak and in the briefing your dive guide says don't go below 5 on your NDL. On the dive you see an awesome turtle and want a closer picture. You glance at your NDL and see you are at 8, "I have 8 minutes" you think and drop down 20 feet and snap the pic. Satisfied you begin your ascent checking your air and then your computer to find your NDL is at 0 and you are in deco! |
