Shimano Terez Saltwater Casting Rod - Using Shimano's Spiral X and Hi-Power X technology Shimano has created the lightest and most powerful rod ever built. With EVA grips and custom Shimano Aluminum Reel Seats matched with the new Fuji KW Alconite frame guides, the Shimano Terez Saltwater Casting Rod rod is built to perfection. In the Shimano Hi-Power X construction, the blank's outermost layer is diagonally wrapped with carbon tape, which forms an array of "X" shapes. The width of the tape, its winding angle, and the part of the rod being wrapped, are fine-tuned according to the target fish species. This felxible manufacturing process allows Shimano to adjust these wraps during construction for precise actions, enhanced overall strength, and added twist resistance. In short, Hi-Power X construction delivers sharp and crisp rod control by the angler. Shimano's Spiral X construction consists of three layers; a middle layer of vertical fibers, and an inner and outer layer both comprised of carbon tape that tightly winds the blank diagonally in opposite directions. By using this carbon tape in place of a conventional horizontal fiber sheet, Spiral X achieves enhanced compression ridigity and enhanced torsional rigidity without adding extra weight. This in turn facilitates instant power transmission for precise casting and fighting fish. Through its exclusive lightweight structure, Shimano's patented Spiral X construction enhances angler's "catching power".
