Using a leader in fishing provides several benefits, including increased abrasion resistance, reduced visibility, and improved casting distance. Leaders are typically made of a stronger and more durable material than the main fishing line, such as fluorocarbon or monofilament. This added strength helps prevent the line from breaking when rubbed against rocks, coral, or the fish's rough mouth, especially when fishing in areas with sharp obstacles. Additionally, leaders are less visible underwater than the main line, which can be crucial when targeting wary fish in clear water. The reduced visibility of the leader can increase the chances of getting a bite. Moreover, using a leader can also enhance casting distance, as the thinner diameter of the leader creates less drag in the air, allowing for smoother and longer casts.
