Heavy-duty nylon monofilament shock leader line. 140lb breaking strength, designed for big-game ocean fishing where sudden shock loads are expected. 50-meter spool. Low stretch for better hooksets on large fish. High abrasion resistance for durability when fighting powerful species like tuna, marlin, or swordfish. Slightly visible in clear water but provides the strength needed for terminal tackle.

TARGET USE: Heavy shock leader for big-game ocean fishing with heavy tackle or when targeting large pelagic species
