The LineSystem Boat Egging Leader Fluorocarbon line is specially designed for squid fishing, with a refractive index nearly identical to water, making it virtually invisible to squids, which have excellent vision. This leader material offers excellent resistance to abrasion, ultraviolet radiation, and harsh environmental conditions, ensuring it retains its strength and durability over time. The spool comes with an elastic bandage to prevent accidental unwinding during storage and transportation, making it a practical and reliable choice for squid anglers.
