When you're serious about ocean and deep sea fishing, Shimano Tekota® is built from the ground up for hard-cranking durability and resisting the ravages of salt water. Sturdy diecast aluminum keeps moving parts in alignment for increased efficiency and durability without adding excess weight. Anti-Rust Bearings (A-RB) are up to 10 times more corrosion-resistant than standard ball bearings. Super Stopper one-way roller bearing eliminates backplay for more solid hooksets while Assist Stopper back-up anti-reverse system reduces the stress placed on the roller bearing. Dartainium drag material provides a wide range of drag settings and the smoothest performance in a Shimano reel. Tekota LC models come with an easy-to-reset line counter mechanism. Bottom line: this reel is perfect for fishing the sea and Great Lakes.
