Teramar XX rods incorporate Shimano’s proprietary Spiral X and Hi-Power X technologies to enhance power transmission through the rod blank for increased casting distance and lifting power while also reducing blank twist during tough battles. Each Teramar XX series of rods are designed and engineered for specific regions — Northeast, Southeast, Southwest and West Coast — so whether you’re fishing for stripers in the Northeast, redfish in the Southeast or Southwest, or salmon on the West Coast, Shimano designed a Teramar XX rod to fit your fishing needs.
