I'm going through my divemaster program and feel really nieve. I have only got PADI certifications. That's all that I have ever had the chance to get. I haven't even gone diving with someone associated with anything other than PADI. (even in other countries). Is this unusual? Do I just have PADI tunnel vision? :eek5: I love PADI, but would like to know about others. I know NAUI is very common. Why haven't I seen them anywhere? What's the good and bad on the rest? Thanks..... Jo
