so we've been doing good around buffalo harbor, trolling the outside breakwall at night. but then they just disappear. and i mean we are marking baitfish schools and gamefish(eyes') just below the schools. picking up fish, (we are trolling of course) then on the way back through again everything is gone. now last night we got two right off the bat. one at 845 another at 920. then we couldnt find them or the baitfish. tried out deeper20-30, nothing. are these fish (bait and eyes) moving right up on the breakwall at niight? anyone? it was like dead water on the sonar for hours, so we went in.
