The Daiwa SALTIST4500 Saltist Spinning Reel is a new model for 2016. This spinning reel was made for serious saltwater fishing. This reel was designed to provide reliability and performance. Saltist® Spinning reels are made to withstand the elements. With the rugged and durable reputation of the Saltist name. These reels feature a Magsealed main shaft, Magsealed line roller and (CRBB) corrosion resistant ball bearings for long lasting smoothness and performance. FEATURES: Magsealed line roller and main shaft. "HardBodyz" body and side cover. Light weight Air Rotor design. Air Bail®–tubular stainless for lightweight strength. Digigear™ digital gear design. Dynamic Cut Aluminum ABS spool. Waterproof Carbon ATD Drag System. MAGNETIC OIL: Magnetic Oil is one of a new generation of Nano Fluids that can change density and shape when a magnetic field is applied. CORROSION RESISTANT BALL BEARINGS: Last up to 12 times longer than standard stainless steel ball bearings. AIR ROTOR: The Air Rotor weighs up to 15% less than ordinary rotor designs. Its unique shape reduces unnecessary weight while distributing stress more evenly throughout the rotor for maximum strength. ABS SPOOL: The ABS spool's maximized core diameter and reversed taper mean 100% useable line. No "dead" line buried in a deep core. You can fill it with line right up to the edge of the spool lip without fear of tangles. ABS cause less casting friction for longer and easier casting. The huge spool diameter line flow freely in larger coils and produces less line memory coil. Smaller spool diameter means line flows in tighter coils as well.
