Shimano Terez BW UB Full Roller Rod Blades w/ Rod Butts Shimano Terez BW Uni-Butt Full Roller Rods Set to tame some of the largest of pelagic species with ease, the Shimano Terez BW Uni-Butt Full Roller Rods utilize premium materials and state-of-the-art rod technology to dominate the water column. Shimano incorporated several key blank technologies with the creation of each rod blade, including Hi-Power X, Sprial X, and UD Glass construction, each working together to maintain the rods structural rigidity and strength under load. This allows anglers to efficiently transfer all their energy, ideal for long fights against powerful species such as Bluefin Tuna, Yellowfin Tuna, and more. Its UD Glass technology enhances overall rod strength, while retaining its ability to flex and keep fish pinned, mitigating tear outs. The full roller layout, rod powers, and actions seen on each rod blade adapts perfectly for trolling, chunking, and more, requiring less setups when needing to change tactics of the day. Hi-Power X Hi-Power X utilizes diagonally wrapped carbon tape that runs up and down the length of the blanks outermost layer to reinforce its twist resistance. This also allows Shimano to perfect precise actions for the blank, specifically tuned for big game and the trolling tactics that go with them. Spiral X Construction Spiral X Construction consists of multiple layers of carbon tape that tightly winds the blank diagonally in opposite directions, enhancing torsional and compression rigidity without adding extra weight. This results in an extremely responsive rod blank with instant power transmission, working deepwater fish extremely well.
