"I've never dived without a BC or contemporary regulators. The equipment looks neat, and fun, but I've never used them and have no plans to buy any. ""
I would not expect you would but you can dive without a BC and still use modern regulators, try it sometime in the pool and see for yourself. Not having a BC is not the problem many think it is. They are not life jackets, they are bouyancy compensators, if you don't need to compensate your bouyancy then you don't need one--follow that? Not having a BC does not mean you don't have a suasage and in my case a 15 foot long Ocean Kayak in bright green with a CG approved Type II life jacket on board and all of it being towed just above me in addition to the sausage and an inflatible safety float all rolled away on my person. Solo or not, beach diving unlike boat diving where it can come get you requires one to be able to self rescue.
As to solo, again, I was not telling you to solo but to possibly consider limiting the numbers of people in your group or splitting them up. That way you may get your dive in. The more people in the group--and I assume if one turns back all are supposed to--then the fewer the divers in the group the more likely you are to complete your dive.
Just applying old fashioned logic to a different way of doing things that works really, really well once you think out of the box.
I spent a whole summer back when I was a school teacher, summers off ya know, beach diving in California and living in the back of my truck--lol--there most divers are beach divers, in Florida most divers are boat divers (or spring/cave) so go figure. Sure miss those kelp forests for sure. Talk about some challenging entry and exist points, they got big waves there!!! It was there I first understood the value of a kayak or surfboard as surface support. I also sometimes use a big inner tube surface float but more oftren use that in lakes or rivers.
Anyways, enough of that. Good luck, hope you get those beach dives in. Maybe when the ice caps melt in a few years if Goron is right we will have some great beach diving down in Florida among all the new condo reefs!!!! Looking forward to it actually, is the glass half full or half empty. N
