i've also heard of teams in lake-trout tournies fishing deep-water lakes that hold big fish that are few-and-far-between working in tandem, one man with a jig and a fish-finder, the other about 15-20 yds away with a long string of trolling dodgers that he drops to the bottom and quickly reels up, continuing this process over and over in order to attract the wandering lakers to the area of the jig nearby.
