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. Corvalus’ additional features include: One Piece Diecast Aluminum Frame, Variable Brake System (VBS), Super Stopper, Assist Stopper, Non-Disengaging Levelwind System (400 & 401 only), Two Post Quick Take Down, Rubber Handle Grip, Clicker (400 & 401 only), Aluminum Sideplates, Aluminum Spool and a Metal Series, Corvalus have been approved for use in Saltwater and rated for use with Mono, Fluorocarbon and PowerPro lines.
