Chatterton splashed first and tied in the grapple. His plan was trademark: shoot video, forgo artifacts, return with knowledge. He often used video cameras, which picked up underwater nuances that were beyond the human eye, then watched the tapes topside, learning wreck topographies and planning his second dive. At home, he watched the tapes dozens of times more.
Chatterton's recon routine yields higher results than people who just start digging.
