I don`t beleive that "Commercialization" is the problem. I`ve only been certified for a year and my biggest complaint was that I felt like I was rushed thru my certification. Price is a big deal to the individual that is looking to get into scuba diving, certainly. But if more people were being made aware before signing up and during training that this is a danergous sport that you must respect things might be different. When you have a select few individuals that are not teaching properly and cert. individuals that are not ready it leads to deaths. Please understand I`m not saying that all instructors are like this, or operate in this manner. But it does lead one to question is the instructor not somewhat to blame in this deaths of new divers as well as the diver themselves.
