I think that minesweepers use MAD (Magnetic Anomoly Detection), since that is the primary source for detecting mines and it was further developed for destroyers. I think I remember reading that the Japanese were the first to really refine and effectively implement MAD gear.
I've had single merchants spot my scope at over 3,000 yards at night with the boat stopped. They start to zig-zag, but I usually get at least one fish into them as they pass by. So, super-human abilities aren't only a minesweeper trait.
