Daiwa 2021 Certate SW (saltwater heavy duty) spinning is solid and powerful to catch large games from oceans. It has aluminum alloy monocoque body to hold the largest internal mechanicals square, and to protect them from water. Monocoque body frame doesn't need spaces for screws, and it may hold over-sized drive gears inside.
The drive gears are made of G1 Extra Strong Duralumin, to offer the longest life. Tough-digi-gear has the least gearing noise, while maintain the smoothness for long time.
Mag-seal system is employed at pinion and line roller, to enlong the life of the reel. Mag-seal is the water repellant system using magnetic oil and ring magnets, achieving both ilght friction and high sealing performance. Rotor is made of Zaion, carbon reinforced engineering plastic to make handle turn light for vivid reeling actions. The number of carbon drag washeres is increased for the size of reel to up to 9 to increase drag durability to 200% of previous comparable reels.
LC-ABS long cast spool design has spool lip at the front of spool edge to add 5% distance
