In response to TMHeimer: These were people who were certified in Southern California, the same as me. I'm guess they had all of their ocean dives from a boat.That means they paid more for their certification but apparently got less training for their money.
My mind is a bit foggy these days but I recall that some degree of rescue training was involved (both in 1969 and in 1983) plus they touched upon such things as cave and shipwreck diving and navigation with a compass. At the time I was also reading a lot about diving so I can't verify exactly where I got my information. We were also taught decompression dives but didn't actually do any during the course. Since I don't know what they don't teach now in a basic course it's difficult for me to say what all of the differences were. Of course we didn't have BCs so we learned about proper weighting. Everyone had to do a free ascent from about 35 feet. During the pool training all of our gear would be at the bottom of the pool and we jumped in, turned on our air, and put on all of the stuff. During one exercise our masks were blacked out with aluminum foil and the instructor would do such things as drop our weight belt, turn off our air, or yank the regulator out of our mouth. Hopefully all of the book-learning is still included in even the most basic course as I view it all as necessary. My original course even included a bit of survival training and how to make sushi before I'd even heard of sushi. Since very few people had a SPG we relied upon our dive watch to determine when to surface or head back to the beach. I now know that many of my dives could have been a little longer.
