Description of the game from Adam Spielt:

The players are diving for sunken treasure! Each dive, they must decide anew how much of a risk to take and either dive deeper or take a treasure closer to the surface. But be careful - watch out for the sea monsters! Not all of them are friendly. Excitement guaranteed! The player who could gather the most valuable treasures by the end of the game is the winner! An exciting mechanic, simple rules and a tricky lighting technology.
