I was originally certified in 1987 in college. I dove some but got married the next year and my wife had zero interest (actually afraid to go underwater) in scuba. Years later (2020) I got recertified with my two, now, adult sons. Now in 2020 when I got certified it was to a maximum depth of 60 ft. To go beyond that you need advanced training. However, in 1987, I am almost certain that we were trained to go deeper. I remember learning about decompression tables as well as safety stops. Unfortunately, I cannot find my old scuba book. Was anyone been certified that long ago? Was deep diving training part of your certification? Is advance training for deep dives something that has come along in the past years or an I just misremembering? In 1987 I was certified under IDEA; in 2020 under PADI in case it is agency related.
