I’m not sure just what to think about DIR. There are aspects that I most certainly agree with. Gear standardization, for example, I believe makes sense. The idea that every reef diver should be carrying a 7 foot hose? I’m not so sure.
Like a lot of people, I am interested in learning why and how all divers configure their equipment, plan their dives, etc. in the interest of safety. The article linked above interests me because the author seems to have first hand knowledge about the history and individuals involved in DIR.
