    The diving bell first becomes available after Sequence 6, Memory 1, "Diving for Medicines." Thereafter it becomes available for sale as a ship upgrade for 5,000R.

    Note that you don't have to actually fully plunder all wrecks, you merely have to put the diving bell in the water at each.

    XEN610Five of those locations are not shipwrecks and do not need to be visited. The seven locations are listed in the 360 version.

    To add to the above solution. You can see on the map if you have previously put the Diving Bell in the water at a shipwreck location if the Fast Travel option is available. A shipwreck can still be visited on the map and is "visited", but that will not be enough for the achievement.
