USCG Duane was decommissioned after a long career. She was sunk as an artificial reef with her hull intact, but her hatches open to provide access points for wreck-certified divers. The card features 3D-rendered images of the wreck on both sides; a brief history and description of the wreck; important depth information and a suggested route to assist in navigation; six key species likely to be found on the wreck and where to look for them; and ratings on the level of difficulty, current, depth, reef and fauna for the wreck.

Waterproof 5.5" x 8.5" card features sturdy lamination and hole for lanyard.
