in Beaufort and Hilton Head SC too.
But, it isn't all that easy for some people.
The diving is very low viz... yes zero. The current is bad sometimes.
You don't dive with buoyancy in most all of these places. You overweight yourself and dig around on the bottom so that makes visibility even worse. We call it braille diving.
It can be very uneasy too. Once we were night diving looking for teeth and fossils (believe it or not I can see in the dark waters with low visibility better at night) and something swam across my body longways. I could feel its drag on me and it was bigger than I am tall. I have never peed in my wetsuit before but I thought I would that night. I am pretty sure it was a shark but I couldn't see it. The area is prevalent for sharks. I just remember holding very still and the thought of what the h3ll are you thinking went through my head plenty. I don't mind diving with sharks. I've done it and with several at a time, but when you can't see them, that makes you feel funny. I don't think it was a fish because of its movements, it was in the sound, and like I said it was over five feet long.
Now, in the Cooper River you have to watch for the Gators. That makes me more nervous than sharks. We have a cute little gator (maybe 2-3 feet long) on the island that I coax to the shore. He's so cute but I am not comfortable diving in low viz with one. Especially these, four/five+ feet long. I had some friends that dove there a few months ago and they said that every time they got into the water, three gators would follow them in. When they got out for surface interval, the gators would go to the bank and lay there and watch them. On the next dive, they were followed in again.
Anyway, if you want to come braille dive in the Carolinas, give me a shout. R
