The MicroModule Gear technology creates a smooth retrieve by utilizing smaller teeth to increase the number of contact points between the drive gear and pinion gear.

X SHIP provides improved gear durability. By supporting the pinion gear on both ends with bearings, the pinion gear maintains precise alignment with the drive gear. This increased support allows the gears to stay in the same position under the heaviest loads. X-Ship technology also eliminates the friction between the spool shaft and gear to further benefit anglers with enhanced casting performance and casting distance of lighter lures.

The HAGANE Body is a metal reel body with high rigidity. The body rigidity and impact resistance virtually eliminate body flexing on the reel while fighting a fish. The result transforms the angler's actions directly into cranking power,

DC brake system perceives the changing spool speed and controls brake power with microcomputer, and provides the cast-performance of long distance and anti-backrash. I-DC4 brake can be set easily with 4 dial adjustment, covering to each line.

CI4 is a resin material reinforced with carbon fiber that is lighter and has a higher strength than conventional resin material. CI4+ is an advanced version of the original CI4 material.The rigidity and durability have been greatly improved from original CI4 material while maintaining the lightness of the material, making it possible to reduce the size and weight of the reel.

The CROSS CARBON DRAG provides the smooth drag release and the durability.

S3D SPOOL leads to significantly reduced spool vibration. This creates an smooth feeling when casting.

S A-RB bearings are put through the same process as Shimano’s A-RB bearings but feature shields on both sides of the bearings. These shields reduce the possibility of salt or sand inhibiting the rotation of the bearing.

SUPER FREE SPOOL reduces friction on the spool shaft during the cast and enhances casting performance.

Models determined usable in saltwater.
