The BG series ranges from ultralight freshwater actions to heavy big game saltwater models. With a strong black Anodized Machined Aluminum Housing and a solid screw in handle this reel is extremely rigid.AIR ROTORLighter, stronger and more balanced than any rotor system that’s come before, ‘Air Rotor’ delivers a great leap forward in rotor design and function and delivers the ultimate reel sensitivity and rotational balance.ATD-DRAGDaiwa’s Automatic Tournament Drag uses an improved drag grease that exhibits a low viscosity at rest, yet becomes more viscous immediately after drag start up. This reduces initial drag start-up inertia and combined with the structural changes of the ATD Drag System results in a smoother drag from the initial hook up.DIGIGEARDaiwa’s first generation of digitally engineered gear design ensures a perfect mesh between ultra-tough drive gear and pinion gears for optimized speed, power, durability and smoothness.
