The Sienna series of threadline reels come with four ball bearings for smooth and effortless operation, and a precision gear system built for reliability and performance. The aluminium spool is precision made and has a multi-washer drag designed to handle fast running fish. It also features the Shimano Dyna- Balance system that eliminates rotor wobble when winding. Super Stopper II anti-reverse provides instant hook-sets, and the oversized Power Roller line roller assists the AeroWave Oscillation to produce a perfect line lay on the die-cast aluminium spool. The feature-packed Sienna range of threadline reels from Shimano represent excellent value for money, yet there is no scrimping on quality and performance.
