This special dive map card of the shipwreck of the Duane is a handy
reference guide for visiting the ship or while briefing a dive plan with
your dive buddies. It`s waterproof and depics the three mooring buoys with
down lines to the different ends of the ship. Yellow arrows denote a
suggested swim through plan, and the depths of different areas of the ship
are clearly marked. This is the best tool for previewing the features of
this artificial reef that lies off the coast of the Florida Keys.
