It doesn't matter what you're doing-start with a solid base, and everything you build on it will be better. So we started the Corvalus with a one-piece diecast aluminum frame that will stand up in battle. Add Super Stopper anti-reverse for solid hooksets, and our Variable Braking System (VBS) for easy casts, and there will always be a place for Corvalus in your armory.One Piece Diecast Aluminum FrameVariable Brake System (VBS)Super StopperAssist StopperNon-Disengaging Levelwind System (400 & 401 only)Two Post Quick Take DownRubber Handle GripClicker (400 & 401 only)Aluminum SideplatesAluminum SpoolMetal SeriesApproved for use in SaltwaterRated for use with Mono, Fluorocarbon and PowerPro lines
