Creative driving can tell you if fish are in an active mood.
Speed is always a critical factor when trolling – some days the fish want fast-moving lures, and other days they want them barely moving forward. When making my first trolling pass over an area I make a habit of using broad S-turns to help me figure out what the fish want on a given day. When you make a turn,the lure on the outside of the turn speeds up, while the one on the inside of the turn, which doesn’t need to travel as far, slows down. If I find my first two or three fish all come from the outside rods, for example, that’s my cue to speed up a notch.
S-turns can also help you determine if the fish are higher or lower in the water column, since a fast-moving lure tends to dive deeper than one barely plodding along.
