Hand fatigue protection Power-absorbing grooves help reduce hand fatigue while also minimizing main line wear and issues with the rod guides. This design lowers the risk of snagging, contributing to smoother, safer fishing. Durable aluminum alloy construction Robust aluminum alloy build provides long-term stability and improved durability. It resists wear and impacts, supporting an extended functional life of the fishing reel line roller assembly. Optimized line grip The grooves securely hold lines, minimize twisting, and improve grip. This delivers stable performance with quick recovery after loading and unloading. Pressure-relief ring A wide ring follows natural hand curves and distributes weight evenly for greater comfort during extended fishing sessions. Use scenarios - All-day fishing on freshwater or saltwater, where comfort and reliable line handling are important. - When using braided or heavy lines, where line twist and wear are more likely, to maintain smooth operation. - In scenes requiring quick line recovery and stable performance during big-fish fights or during prolonged retrieves.
