For a unique, stealthy approach to your trolling presentation, use Stealthcore® Lead Core! Unlike other lead core lines, Stealthcore® features alternating 30-foot sections of black and red line. Why black and red? The black section is neutral and nearly invisible while the red section loses visibility as it sinks in the water, becoming more neutral. This lead core line works great in clear waters, as it virtually disappears into the water column. If you are a serious tournament angler, charter captain or a recreational angler, Stealthcore® Lead Core will help you put more fish in the box! See the results, not the line!
