Doppler, a question for you as you are the architect of the course. Would not make sense that a Dive Instructor of any agency would be able to receive the certification without the course or perhaps the practical section of the course, certainly he can read and self train. A divemaster or an instructor,or highly trained technical divers is responsible not only for himself but for the well being of the divers he brings with him, he is competent in navigation, air consumption, when he dives he certainly does not rely on his student? what are you thoughts, is there an opportunity here to provide a reduced version of the certification once someone reaches a certain classification level?
