The Panther Martin FishSeeUV 6-Pack Spinner Kit includes some of the deadliest inline spinners you can throw to catch fish on cloudy days or in murky, muddy water. These lures are eye-popping enough in normal light, but put them under a black light (replicating the way fish see them) and you'll be amazed at how well the brilliant ultraviolet colors and fluorescent orange bead stand out from the background. You'll find them to be extremely effective at triggering strikes from trout, bass, kokanee, salmon, steelhead, and many other species.
