My first dive was at age 12, in about 8' of water after being given about 15 min. worth of instruction from a non certified diver of many years. I never looked back, and had in the area of 700-800 dives in before I was unable to get a tank pressed without a "C" card, thats the only reason I became certified. Many of the divers I went with were never certified, and were some of the most experienced and trusted partners I have ever been out with. I wonder how those of us that learned this way survived?
