I got my PADI OW certification, and on my first dive after the course, the DM said we'd go down to 80 feet. I said that I only had OW, which he knew because this was the same place I'd just taken my OW course, and he said that's all right, no problem. I thought, maybe it's because a DM can take a diver deeper than that diver is allowed to go when just diving with another OW diver as a buddy.
On my next (and only other) dive trip, the dive shop owner said we'd be diving to 80 feet, and I again expressed my concern, as above, and he said, don't worry, no problem. We were always diving with a DM (maximum 6 divers per DM).
My question: was it really stupid of me to dive to 80 feet? Does the presence of a DM make the difference? FWIW, both times were in the Caribbean, warm water, excellent visibility, daytime dives.
There are many avenues to travel with this answer...
First and foremost, there are no Scuba Police monitoring your diving and there are currently no laws on the books in the United States or most other countries pertaining to Scuba limitations. The 60ft depth is an arbitrary number dreamed up by lawyers and industry insiders to do two things;
1. Protect dive instructors, shops and agencies from liability should you exceed your training limit. In other words, go to 80 feet and get the bends, everyone is absolved from liability because you broke the limit you were trained too. A clever way to self protect by all involved.
2. A way to make you go back into dive shops for additional training AKA spend more money for "Deep" certification.
Reality Check: If you paid attention in class, learned your dive tables and or how to use your computer... and you truly understand your tables and/or computer, you are quite capable of diving to any depth within the accepted recreational diving limit of 130 ft.
The bigger question is are you personally ready for that challenge? Are you prepared mentally? Do you have the proper equipment for deeper diving? Are you self dependent or are you placing your life in someone elses hands - such as the DM?
My first dive after certification was to 135ft. I didn't really think about it... because back then, 130ft was the accepted limit and it was what we were trained to. This was before the lawyers got involved and the training agencies got greedy.
If you feel comfortable at 80ft... you're likely ready for it. The decision of how deep to go rests entirely on your shoulders. Was the DM smart to take you there? He traveled outside of his legal coverage zone when he led you down there and told you it was OK. He could be fired from his job... and wouldn't have been covered by his insurer had something happened to you... which means you wouldn't have gotten a nickel from a broke DM. Maybe from the operator... who would have been fighting saying he didn't approve of that depth... and you knew full well you weren't qualified to go there... a legal quagmire.
In any event... I'm not recommending you do anything but stay within your training limitation of 60ft... then I might me liable... but as far as what you decide... it is entirely up to you... because you are the one that lives... or dies from the consequences. Don't let DM's make that choice for you.
