This design incorporates a one-piece frame and a one-piece threaded side plate. Because screws are not necessary to attach the side plate and hold the main gear, the interior space in the body is greater allowing for a larger more powerful gear held in place by the lighter, sturdier body rather than the traditional side plate.

Shielded for extra protection. Unlike ordinary "corrosion resistant" bearings with un unprotected open race, DAIWA's CRBB ball bearings are shielded to seal out sand, fine grit, salt crystals and other abrasives for even longer life. CRBB ball bearings feature an 12 times higher corrosion resistance than usual ball bearings.

DAIWA's unique waterproof structure creates a wall of magnetic oil in the gap between the body and rotor, blocking out seawater, dust, and other elements.

MAGSEALED bearings (MSBB) - have been designed to last longer than ever. The balls are encapsulated in a completely waterproof bearing. The inner and outer rings are magnetised and joined by waterproof and highly stable MAGSEALED oil. The casing is 100% protected from impurities. The smoothness is beyond comparison to a waterproof industrial bearing: MagSealed oil removes the need for a joint, meaning that you won’t detect any friction on the wind. These bearings are placed either side of the drive gear in our flagship reels.

The progenitor of these construction technologies, developed by Daiwa to obtain structures with performances similar to those of metals, at a lower cost because they do not require anti-corrosion treatments. The characteristics of this material are simply stunning: for the same volume it weighs 50% of aluminum and its structural rigidity approaches that of magnesium.

The ATD Tough uses carbon washers to achieve high durability. It pursues smooth start and tracking, allowing you to concentrate on the fight without worrying about the drag setting.

Compared to conventional spools, the LC-ABS Spool design has been shown to increase the average flight distance by approx. 5% due to its reduced weight and modified shape. LC-ABS Spool design grants anglers a premium casting experience.

The body structure has been simplified by removing the stopper. The decision to remove the stopper, which is a route for water and foreign objects to enter, not only reduces weight and improves waterproof performance, but also minimizes the risk of sudden trouble when fishing in harsh environments or with large fish.
