R2D2 was a famous robot in the Star Wars movies. This air compressor in the sunken Fujikawa Maru engine room has also been given the name and is a must-see when diving the Truk Lagoon/Chuuk wrecks in Micronesia (fly to Guam and hang a left). In order to get a good R2D2 photo, you have to be first off the boat and make a bee-line to the compressor at about 130'. If one diver arrives before you and swims into the compartment, all you'll see is R2D2 in a haze of sediment (no matter how careful the diver was). I was forgiven for blocking the entrance to the compartment for the less than the 30 seconds it took to shoot seven frames of R2D2 in clear water. Thanks everyone.
