John,
Been there in your situation to a much lesser degree and that was my main driver for a PLB and a lifeline as well. If you dive in any areas that have any chance of current you would be crazy not to get one. As I said to my wife (and minister for finance), it would be a nice thing to be floating in the water realising you may die with no way of telling people where you are thinking, gee I am glad I saved that $800.
