A total of six seals are used to create the new Water Tight Design used in the Spinfisher V. Whether you dunk the reel in the surf or let it ride in the spray all the way home, you don't have to worry about saltwater getting into the gearbox or drag system. A truly sealed drag system with a total of three HT-100 drag washers. All HT-100 washers are greased for smoothness and longevity. Extreme range, endless adjustment and a large diameter drag knob so you can easily crank down to max drag. No backing needed because the rubber gasket keeps superline from slipping. Eliminates the question of how much line you have left when fighting a fish. The three lines on the spool flange let you know when you have 1/3rd, 2/3rd or a full spool of line. Also if you respool often these lines find you a benchmark for backing your superlines with monofilament, which will help eliminate wasted time and line. The Live Liner drag (available on 4500 and 6500 sizes) was built for fishing live bait.
