Daiwa's Caldia 4000 reel is completely structured in Zaion, a carbon composite with a higher incidence of active fibers. This allows you to better perceive the vibrations, to feel when the bait meets an obstacle and therefore to react faster. In addition, the Mag Sealed magnetic membrane, made up of a special oil that binds to the metal, protects the reel not only from salt water, but also from the effects of dust. These are just some of the wonderful features of the Caldia 4000A Daiwa reel, an indispensable purchase for any true fishing lover. - Body in Zaion; - Air Rotor rotor; - Ultimate Tournament Drag clutch; - Body protected by Magsealed technology; - Air Bail headband; - Digigear II technology; - Twistbuster thread guide roller; - 5 ball bearings including 1 CRBB; - Infinity Anti Reverse; - Latest generation ABS II coil; - Monobloc aluminum handle.
