The cool water slows the reactions of predators. At this time fish are located in deeper water and you will need to rely more on a good-quality echo sounder in order to find them. The best method for accurately and slowly presenting a large rubber lure, is with vertical spin fishing tackle. You can expect large zander and pike, or even huge perch to attack large rubber lures. You can also try a drop shot and neutrally buoyant wobblers with natural colours.
