Durable aluminum alloy construction delivers long lasting stability, resisting wear and shocks to maximize the product's effective usage duration. Antislip grooves provide precision line contact. They match line contours to prevent unwanted movement, reduce tangling risks, maintain operational consistency, and restore alignment effortlessly. Even weight distribution fits hand contours, minimizing hand fatigue and delivering a balanced, protective feel without uncomfortable squeezing. Groove design is engineered to absorb force, reducing mainline damage, preventing reel accidents, and lowering snagging risks while protecting hands for safer, more efficient fishing. Key attributes Material: aluminum alloy Function: fishing line puller Performance: stable, safe, and efficient operation Use scenarios On a boat during trolling or deepwater fishing to maintain line tension and prevent tangles. Shore casting or bank fishing to reduce line snags and protect hands during long retrieves. During line maintenance, respooling, or knotting to minimize snag risks and protect the reel and line.
