I am always amused by people who take everything to extreme, immersing themselves in the either/or fallacy. As some have pointed out, we already have lots of government regulation of scuba. Any change would be a matter of degree. Here in Colorado and the neighboring states, nearly all dive sites are on some government's property, and they make the rules. They tell us where we can dive (now where are the really, really crappy parts of this reservoir?), when we can dive, and under what circumstances (better have a buddy and a flag). So the only real question is how far you want that control to go. To illustrate the real problem as I see it, let me describe a real issue a group of us had trying to teach a large group of students in Carter lake, Colorado.
It was August, and we had been teaching classes every other week since the end of Spring. We were setting up the dive site in preparation for the classes when the rangers arrived to tell us we were not on their list of approved and insured instructional programs. How could we not be, we asked, since we had been coming there all summer with no problems?
Sorry! We were not on the list. No instruction could be carried on that weekend. We and all your students would have to go home--no refunds on the entry fee.
We called the shop. They had copies of the required forms showing we had done all the correct paperwork and gotten confirmation of our approval. They could fax copies immediately.
Sorry! That didn't matter. You have to be on the official list, and there is a specific person who puts you on that list. She does not work weekends. When she came in on Monday, she could put us on the list. Until them no diving for us.
Can't you see that this has to be your mistake, we asked? Isn't it obvious that we have done everything right, but somehow you have mistakenly left us off the list?
Maybe so, they said, but if you are not on the list of approved dive operators, you can't dive here.
All of the above is what I was told. I was just a DM then, and I was in the water setting up the dive platform for the students to use. They did not see me get out of the water because of the heated conversation. That was lucky. If they had seen me, I would have been fined $100 for being in the water without a buddy. I would have been fined $100 for being in the water without a dive flag, even though I was in a restricted zone open only to diving. I would have been fined $100 because I had left my certification card at home.
Just as things looked really dire, one of our group, looking at the list of approved operators, saw that one of the approved operators was owned by someone he knew well. He got out his cell phone and called him. After a few minutes of explaining the situation, he handed the cell phone over to the rangers. The owner of that operation told the rangers that he had just hired all our instructional staff for that weekend. We were now part of his shop, and we had permission to do our instruction there. The rangers were furious. They tried to think of anything they could do, anything at all, to screw us over and keep us out of the water. They could not come up with anything, and we were saved. They were so frustrated that they forgot to ask the instructional staff to produce their C-cards, which would have worked, since none of us had them.
The next day they tried it again, telling us we would not get by on a technicality this time. Fortunately, try as they might, they could not think of any legal way to screw us over, as much as they clearly wanted to. We had even brought our C-cards.
And so, I do recognize that the government is already involved in regulating scuba. I would just prefer to keep it at a minimum.
