Jean-Claude Roubaud's passion is the sea. He's a diver, and for over 15 years has been making his childhood dream come true: earning his living finding sunken treasure. To be more precise, Jean-Claude has become an expert in underwater archaeology. Through his mask he's seen enough treasures to make a museum conservator blench - and Jean-Claude's not one to boast. In 1991 he met a man with the same enthusiasm: Franck Goddio. With his team, Jean-Claude gained enough experience to become a dive master, exploring the world's seas to recover treasures lost in the briny deep.
