CoreSolid Body (Magnesium): Integrates the B-Side Plate, levelwind guard and frame into a solid one-piece construction. This delivers an unprecedented feeling of rigidity and sensitivity, and is the first design of this type in a low-profile baitcast reel. HAGANE Body: The HAGANE Body is a metal reel body with high rigidity. The body rigidity and impact resistance virtually eliminates body flexing. The result transforms the angler's actions directly into cranking power. It's efficiency through strength. MicroModule Gear: The MicroModule system creates a smooth retrieve. The new gear set makes use of smaller teeth and more of them. This means that there are more contact points between the drive gear and pinion gear. The result is a more efficient gear train with less gear feel. X-Ship: Provides improved gear durability. By supporting the pinion gear on both ends with bearings, the pinion gear maintains precise alignment with the drive gear. This means the gears will stay in the same position under the heaviest loads. The added benefit is that friction between the spool shaft and gear are eliminated. This will enhance the casting performance of the reel with lighter lures, and allow for longer casts. MGL Spool III: An ultra-thin spool that thoroughly pursues low inertia. The spool has a reduction in inertia by about 15% compared to the second-generation MGL Spool by using a narrow shape with a width of 19 mm for the outer diameter of 34 mm. Resulting in unparalleled casting performance.
