Snag and line wear reduction: Innovative groove design absorbs load, reducing mainline wear and the risk of guide or reel snags. Easy to operate for safer, more efficient fishing. Durability and stability: Built with a strong, reliable aluminum alloy to resist wear and impacts, providing consistent stability over years and extending the life of the fishing setup. Enhanced line control: Precisely machined grooves fit lines snugly, eliminating slippage, improving traction, enabling smooth line flow, and quick recovery under load. Ergonomic hand comfort: Natural hand position with no pressure points, minimizing fatigue and delivering lasting comfort during extended fishing sessions. Use scenarios: - All-day shore or boat fishing with braided lines, where keeping lines aligned and reducing wear on lines and guides is important. - Casting and retrieving heavy lures in challenging conditions, where improved line control enhances accuracy and control. - Prolonged trolling or vertical jigging sessions, where ergonomic comfort and stable performance help maintain efficiency. Material: aluminum alloy Function: groove-based line guidance and wear reduction Compatibility: suited for standard fishing setups requiring precise groove control Performance: reduces wear, enhances control, improves safety and comfort
