I really didn’t want this question to be about which agency was better or doing this or that. I really believe all the agencies are caving into commercialism to an extent. Diving is difficult and inherantly dangerous. We are not meant to breathe under water. Why would you say, "Here is the tank, stick this part in your mouth and, oh, don’t hold your breath. Have fun!"
I’m not advocating returning to the grueling, Navy inspired basic classes I took but I do believe instructors from ALL agencies owe their students a better education.
