Redfish have an exceptional sense of smell, but their eyesight isn’t too keen. That’s why these aggressive feeders will take a shot at almost anything that gets close and resembles food; they’ve got to grab a meal while they can see it. Use this behavior to your advantage when sight-fishing reds. As soon as you spot a fish, draw an imaginary 2x2-foot box around its head from the gill plates forward, extending past the nose. That box is your casting target. Regardless of fly pattern or lure color, if your offering twitches through the money zone, it will get eaten most of the time.
