"Whiting" brought a more advanced sidescan sonar – only recently installed aboard the ship – to the effort that allowed a higher resolution and a higher search speed.While "Whiting" searched one area in dense fog, dodging lobster pots, "Rude" found and marked a high-confidence target in another area that appeared to be the missing Saratoga and radioed the United States Navy rescue and salvage ship about the discovery; "Whiting" then searched the same area to gain higher-resolution images of the target.
