The Yamatoyo Harris Fighter Leader is a strong and hard-wearing fluorocarbon leader. Fluorocarbon leaders have a low visibility under water, which is important when fishing in clear water where line visibility has the potential to spook a fish from your bait or lure. It is also useful if the fishing is shut down and you want to try some finesse-style fishing. This line is rated to 4-pound and comes with 50 metres, so you have plenty of leader material for your next fishing trip. The 4-pound strength is ideal for estuary species, such as bream and flathead. It is also perfect to use when trout fishing in rivers or dams.
