Three common cold-water jigging errors are using jigs that are too light, not moving the jig enough, and using line that's too heavy. You need the jig to reach the bass, which are typically holding deep, and you have to keep the jig moving constantly if you're going to coax a bite. A jig that's too light may not even reach the right depth, and even if it does, you may not detect a strike. Opt for 1/4- to 3/8-ounce jigs, and spool with light braided tipped with light fluorocarbon leader. I find that continuous hops often get lethargic bass to bite, and I avoid dragging at all costs. Not only do you get bored and hung up constantly, but dragging also isn't doing enough to say, "Here I am. Bite me!"
