Adding an extra Evo R Salt Spool to your kit allows you to keep both floating and sinking line on-hand, or switch between different line weights in a flash. The quick-release function allows for easy changes on the water, and the Evo R Salt performs equally well in both left- and right-handed retrieve modes. The Evolution R features a fully sealed drag with a bonded carbon fiber and stainless steel interface that provides 30 pounds of smooth power to take on strong fighters as they rip line off the spool. The body is machined, anodized aluminum for strength, rigidity, and a sleek look, and it has the durability to withstand repeated exposure to saltwater over time.
