Years ago before I went Rebreather, I read a story in ?? mag about an
initial Rebreather experience. The author dove a wall and encountered
sharks. His rather belated self-consciousness came out as:
"I must have looked like a big turtle."
This has always stayed with me...
I've been harassed on deco by a hammerhead. On OC.
I had plenty of regs available to shoo him/her/it away.
Just one more thing to be paranoid about when bubbleless ...
