.......It's harder to ruin the vis in the ocean so coral head hopping isn't necessary.
But that's what your proposed quarry divers would have to do, since it is of course as you say, "not realisitic" to expect buoyancy control.
Most educators would see a benefit in teaching a diver the basic skills with which they could use in all environments, I hope.
Don't get me wrong, I once watched a BSAC diver leap from coral head to coral head in Cuba a few years ago, so I understand vis isn't the issue there.
He did make me laugh my **** off when I saw his bloody knees when we got back on the boat. Now that could have been dangerous had I been standing too close to the entry/exit area and fallen over.
In Gilboa, there's more than enough platforms and "furniture" for divers to fall on instead of the bottom.
The problem is they're raining in from everywhere, to the point where it's hardly worth going anymore. I can get zero vis with an e-coli-twist at a quarry closer to us and not spend near as much to get there.
I'm not sure that in the last 4-5 years that I've ever been there on a weekend where I didn't see the meat wagon show up for some train-wreck.
I'm actually getting worried that the State is going to shut him down. If this was Canada........well, I digress,...if this was Canada he would have never gotten it off the ground in the first place.
