Radiant's new Ultra Violet Tubing in 4 sizes is the newest in tackle technology. The tubing can be used in many ways to enhance you fishing success. It has now been proven that predator type fish (sport fish) all see reflected ultra violet light down deep where sunlight fails to penetrate. All bait fish, octopus and squid reflect ultra violet light. It only makes sense to enhance your lure by adding some ultra violet reflective material to it. The tubing is most effective when placed over the shank of your hook, or just in front of the hook which is the simplest way to add the ultra violet effectiveness to your lure. When placed in front of the hook, the tubing also acts as a protective shield for you mono line that is highly susceptible to sharp teeth and knicks. Tubing diameter ranges from 1.0 mm to 3.5 mm inside diameter - see 'drop down menu' on previous page.
