Before I get crucified for my belief in the dive cert system, I would like to clarify myself by saying that I very much respect a person with experience backed by well-rounded theoretical knowledge. I certainly am not a c-card enthusiast and I do not believe that possessing a c-card makes me anyone an excellent diver. I believe the basic cert classes is the best way to gain the basic knowledge needed to better understand the sport of diving. The rest of the stuff you learn, you learn through experience. I am particularly not fond of cocky c-card collectors who think they know it all because of their impressive card collection. Just like in my line of work, just because some people hold a P. Eng. designation does not mean they know it all. Most of them don't have the practical field experience to back up their claim.
In this scenario, we do not really know who goes out with the uncertified lady to dive the Coronados. What are their qualifications, if any, or skill level. For all we know, they might just be a bunch of dare devils. Of course, there is also the possibility of this lady going out with skilled and experienced certified or uncertified divers. There's all sorts of possibilities. From my point of view, I consider the worst of the scenarios as the basis for my input. I do respect others' opinion and take on this matter as well from different points of view. However, with the lack of information concerning this matter, it is really difficult to say that the uncertified lady diver is in good hand or not everytime she dives the Coronados.
