Trevala F Series Jigging Rods feature Shimano's next generation of TC4 construction using a high carbon rod butt section that is fused together with a TC4 tip section. This new blank design gives you the pulling power of TC4, but with less weight and increased sensitivity. You will notice an improved recovery rate, which will increase jigging action and increased hook-ups. Custom shaped black diamond fore grips and custom shaped EVA rear grips for added comfort while jigging. The new F Series is Shimano's top of the line jigging rods. This series is an excellent match for Shimano's Trinidad and Torsa Conventional Reels, and Shimano Stella Spinning Reels. Features New Concept SIC guides. Specifically developed to be fished with the deadly Shimano Butterfly jig system, the F Series rods are the ultimate in jigging rods (the TFS58XXH rod features aluminum gimbal).
