we went out fishing today, there was a boat with father and 2 8 or 10 yr olds with him, when we got to the area where they were, they were catching crappie on every other cast, i noticed he was constantly moving, and i noticed he was was looking at probably some kind of fishfinder, we caught about 5 in the area where he was and they probably caught 50 all released, they went in to shore for an hour or so, so i went over where they were, we could not catch nothing, so they come back and we moved away from their spot, they get there and started catching fish after fish. i am so puzzled, i did ask if they were using artificial s and said yes. i noticed they were not casting out at all, seems like they were vertical jigging. i tried that too no luck, what in the world are we doing wrong. we were fishing in 10 to 20 ft of water, when i got into shore there were a few shore guys fishing and said they were there the day before and was doing the same thing
