Newbie question from an old timer. I was certified in 1973 and I guess either I missed the line about not exceeding 60 ft or I forgot it. Has this limitation always been in place? I am AOW certified but my wife isn't. She has over 400+ dives and we often (usually exceed 60 ft) max depth. We dive the Carribean if that matters. It has never stopped us from a dive, never stopped us from diving deeper within our comfort level and never been questioned about our depth upon returning from a dive. Has this limitation always been around? I would hate for the SCUBA police to come haul her off. Thanks Bill and DeeDee ( old timers who are just curious )
