By inserting O-rings in the inner and outer diameters of bearings and the outer diameters of bearings, the degree of adhesion to the shaft and frame is increased and rattling is reduced. Silent tune that eliminates rotational loss of the spool and provides high quietness and smooth rotational feeling.

The next generation of Shimano's flagship baitcasting series is here: The Antares combines unrivaled casting performance with an elegant and sophisticated design. Featuring Shimano's new MGL Spool III, Antares' spool inertia has been reduced by 15% for effortless and accurate casting of both lightweight and heavy lures. Additionally, S3D Spool and SilentTune minimize bearing vibration for smoother and quieter casts. Antares' magnesium HAGANE Body provides a lightweight rigidity that's unmatched in its class. X-Ship and MicroModule Gearing offer silky smooth rotation, while SVS Infinity braking allows for precision adjustments on the fly.
Key Features

MAGNUM LIGHT SPOOL III [ MGL SPOOL III. ]
By significantly reducing the thickness of the wall, we have achieved a low inertia that is much higher than that of conventional models.
Castability of a different dimension that can be decided at will, whether it is a long throw to a distance or a short cast with a low trajectory.
The state-of-the-art Magnum Light Spool III, which stretches lightly as far as possible, is installed for the first time in Antares.
The level of "rise" and "stretch" are different

Thinning of spools
Cross-sectional comparison of the second generation Magnum Light Spool and the Magnum Light Spool III. Pushing the boundaries of thinness, we achieve low inertia without sacrificing durability.
The first generation Magnum Light Spool and the second generation Magnum Light Spool have evolved, and the third generation is the state-of-the-art Magnum Light Spool III. We have taken on the challenge of further reducing the thickness of the spool and have achieved a significant reduction in inertia without compromising durability. In addition, the spool mounted on the NEW Antares has a narrow shape of 19 mm wide compared to the outer diameter of 34 mm, achieving about 15% lower inertia than the second-generation Magnum Light spool. It achieves a light start-up that far exceeds that of conventional models, a further increase in flight distance, and a significant improvement in trouble-free performance.
Narrowing of spool width
The NEW Antares Magnum Light Spool III, which has been narrowed to a width of 19 mm, achieves unprecedented good elongation and good shedding.
In the NEW Antares, the spool width has also been narrowed to achieve even lower inertia. This change is designed to further bring out the strengths of the Magnum Light Spool III, which has a thinner material to reduce inertia, and contributes to the quick ramp-up and overwhelmingly good rear elongation that continues to release the line until the very end. The exhilarating stretch that goes through everywhere far exceeds that of the conventional model, and once cast, it has reached a level where everyone can feel the difference.
Thorough elimination of rotational loss.
S3D Spool
The S3D spool has dramatically improved spool accuracy by completely reviewing the cutting method. Quietness when casting is improved (compared to our company), and its smooth rotation without blurring creates even more distance.
Silent Tune
There is no doubt that the new Magnum Light Spool III contributes greatly to the overwhelming casting performance of the NEW Antares, but Shimano's unique bait reel technology, such as the S3D Spool and Silent Tune, supports its quick and smooth rotation. By thoroughly suppressing vibrations in various places, such as the shaking of the spool itself and the rattling of the rotating parts, rotational loss is eliminated, quietness is improved, and an exhilarating cast feel is realized. It makes it possible to maximize the performance of the Magnum Light Spool III, which has been reduced to the utmost inertia.
The meaning of promoting "low inertia".
The low inertia results in an improved response to the spool rotation and allows the cast to be cast with less force. This benefit is especially effective for short-range casting. Low-trajectory casts such as crawling on the surface of the water and technical casts such as skipping are also easier to determine, allowing for more precise control.
Why is Shimano so particular about low inertia in the spool? That's because the benefits of low inertia are enormous for bait reels. A low-inertia spool has a faster "rise in rotation" and a "lighter force", a "lower trajectory", and a "lighter lure". In addition, if the inertia is low, it is easy to change the "rotation speed" of the spool, and the rotation speed will drop responsively as the lure stalls after casting, so it is less likely to cause backlash. Conversely, a spool with high inertia is more likely to induce backlash as the lure stalls and the amount of line released decreases. Therefore, it is necessary to control it with brakes, and it is difficult to extend the flight distance.
