You are probably right on this....but in thinking of the quality of the experience, and the health of the underwater life at the BHB, I would like to use the model you see in some Eco-Island type areas--no one is allowed to touch the bottom --certainly NEVER to stand on the coral bottom....they are not allowed to wear gloves( which I would omit as meaningless here), and the operators enforce this....
Yes, all these rules exist. I will use an example of Bonaire; well-known for it's park rules. But how often are they enforced? Has anyone been kicked out of Bonaire or banned since Captain Don calmed down? I think that we don't see it at these places because of the cost. How many brand-new divers, without a senior dive buddy, go to Bonaire? Or is the more experienced divers, the ones who've learned buoyancy control, who make up the larger population of Bonaire divers?
To be certain; there are bad ones. I dove with a group from Brazil who thought fins were for kicking up the bottom (and were promptly reported to Augusto) and a camera-guy who thought nothing of wrenching off a living coral head to get a place to set his camera. He was from another resort...so my solution (in anger, I admit) was to silt-bomb him, and deliver a handful of "inadvertent" fin slaps as I swam about 10 inches over him. Not the best way to handle it, but, damn, it gave me satisfaction.
So, in speaking of taking matters into one's own hands; what can the Agencies and Shops do about this? If we can record instructors and classes screwing up, silting, walking on the bottom, etc.; can we report them to their agencies? A few moments of BS'ing with them can gather their name, shop, and enough info to identify them; and a video of them, and enough complaints should generate enough interest to at least get them a warning...or perhaps their instructor card pulled.
What about a series of wanted posters? You know; "Instructor Silty McKneely wanted for the murder of 5 Nudibranchs and the destruction of visibility", and a picture of the offender, posted widely at the park?
A email and photo send back to the shop they work for? Some feedback left on their shop's and personal FaceBook pages?
The point is that I don't think that anyone at the bridge will ever take action against bad instructors. So what can the community do about it?
