With Daiwas exclusive Magsealed technology, Saltist spinning reels resist saltwater intrusion for extended life in the marine environment.What does "Magsealed" meanFishing reels consist of highly sensitive rotary mechanisms, which in the absence of periodic maintenance, can freeze up due to rust and salt crystallization that occurs when saltwater intrudes. When this happens, an overhaul might save the day—or you may have to say thanks for the memories” and repurpose that reel as a paper weight. So to keep saltwater out, Daiwa "Magseals" the main shaft on all new Saltist Spinning reels. They do this with "Magoil", which is a futuristic magnetic oil developed by space engineers. Daiwa uses "Magoil" to seal microgaps between parts to keep saltwater and other particles out—which was frankly impossible until now.Along with their "Magsealed" design, Saltist reels boast a range of performance features (listed below) that Saltist connoisseurs have come to expect.Saltist Spinning Reel Key FeaturesMagsealed main shaft keeps saltwater and particles outMagsealed line roller (Saltist 5000 and 8000 models) reduces line friction"HardBodyZ" body and side cover withstand impactsAir Rotor maximizes rotor strength and reduces weight for easier crankingTubular stainless steel Air Bail further reduces weightDigigear digital gear design for smooth retrievesABS spool with maximized core diameter and reversed taper for 100% usable lineAnodized exterior surfaces for excellent corrosion resistanceCorrosion Resistant Ball Bearings (CRBB) are specially treated to last up to 12 times longer than conventional stainless steel bearingsWaterproof Ultimate Tournament Drag (UTD)
