The Sustain is built with the power and rigidity to handle a wide variety of fishing challenges while maintaining the refinement and light rotation that Sustain is known for. By combining our water-repellent coating and our specially designed, water channeling, labyrinth construction, X-Protect provides high-level water resistance without sacrificing light gear and rotor rotation. By utilizing the asymmetrical, super-light, perfectly balanced design of the new Magnumlite Rotor, the Sustain requires very low inertia to start rotating, resulting in an immediate, light, smooth feel.
