Diving instruction has standards, qualifications, materials, governing bodies and best practices. So why do we see such poor examples of diving practice? Why do so many new divers struggle with the basic skills? Why do tech divers forget some key techniques? Is it poor instruction or something else?
Why are students not learning this stuff in their scuba classes? The reality is that instructors do teach it, but the students are not learning it, or at least they are not putting what is taught into practice.
