Of course, those were the days of double hose regulators, and before the BCD was even developed. Those were the days of J snorkels and high volume masks with purge valves, and the old Voit Viking full-foot fin.Thalassamania:Diving instruction when it began was 100 hours and 12 open water dives. (1953)
Is that a reasonable comparison to current situations? Certainly technology, and improved skills, have changed some of that, no? After all, it took more training to be a Mercury Astronaut than it took John Glenn to ride along on the Shuttle...
Would seem a reasonable amount of time, certainly. But let's put that in perspective. 40 hours is what a typical semester-long 3-semester hour course in college provides in class time. Even the University scuba course, typically a 1 (or 2) semester-hour PE course, doesn't even require that currently.Thalassamania:When I became an Instructor it had dropped to 40 hours and 5 open water dives (1976).
I'm with you. Can any one even learn to be safe in that time? What does it teach, "Trust your computer, it's smarter than you are? Buckle it on your left wrist. (NO, your other left wrist.)"Thalassamania:I tested a couse for DEMA in 1982 that was 18 hours and recommended against it (the PADI tester thought it was just peachy).
Actually, I dove with an insta-buddy in the late 1980's. He and his wife had each been certified by YMCA, and all they had were two open water dives.Thalassamania:So now where back to the 18 hour couse again.
