Graphite frame, sideplate and rotor for reduced weight. Diecast aluminum spool for casting performance and durability. Varispeed? - By using an oval oscillation gear, we are able to provide a consistent spool speed for an even line lay which results in excellent castability and manageability. Super Stopper® II is multi-stop ratchet system that minimizes backplay for hook setting power. Dyna-Balance® - similar to balancing a tire, we use counterbalancing techniques in the rotor to eliminate wobble during the retrieve. Power Roller® II is an oversized line roller that reduces twist from casting and retrieving and is enhanced with a tapered area on the support to help line get onto the roller quicker.
