I know both of these organizations are first class. My question is this. I have a 25 year old son who wants to pursue a carrer in diving. He has already passed Advanced, and his next stop is Dive Master then Instructor. He wants to do what all of would like to do- go to a perfect resort in the perfect locaton and get a job. Is there an advantage of one organization over another as far as job availability. It seems to me I see PADI mentioned more often than NAUI. His advanced was through NAUI, and he has a good relationship with his mentor. I just don't want him to spend all the time required and then find out it wasn't the best choice. If anyone knows or has first hand knowledge about htis it would be much appreciated. Thanks!
