Treasure Quest is a great documentary style show about a company called Odyssey Marine Exploration searching the bottom of the ocean for lost sunken ships. They are mostly in search of fabled galleons and ships that carried large treasures that were lost at sea. This show Treasure Quest documents the crew involved with Odyssey, their time spent preparing for dives, the troubles encountered with dives, and actual point of view footage from their small unmanned submarine Zeus as they explore the bottom of the seas looking for treasures and trying to fill in the final resting places of these ships into the history books.
I've seen a few documentaries on locating shipwrecks and it's always been quite a fascinating thing to me. If you enjoy documentaries such as those about the Atocha, The Queen Anne's Revenge, the Titanic, U-boat submarines, and other lost and sometimes legendary shipwrecks, then you will without a doubt love this one of a kind series. Some people may not enjoy this series based on the fact that once the proper paperwork is filed on some of the bigger shipwrecks with treasure are excavated. I personally find this to be just as exciting and entertaining as the actual stories behind the ships themselves and seeing the remains of those ships, but some people do have a moral belief that many of these wrecks are tombs and should be left untouched.
If you like documentaries on shipwrecks then you owe it to yourself to watch Treasure Quest.
