Tasmanian Devil Leadcore is an innovative line that allows a lure or fly to be trolled at varying depths without the aid of a paravane or trolling sinkers. The leadcore trolling line is constructed from tightly braided nylon multi-filament woven over a core of pure lead resulting in a fine diameter line with high visibility colour metering every 10 yards. The colour metering makes it easy to monitor the depth being fished.
