The Metanium features a never before seen Magnesium CoreSolid Body to provide both professional and enthusiast anglers with the solid advantage of durability, rigidity and sensitivity while reducing weight. Plus, the MGL Spool III reduces spool inertia up to 17% over the previous generation while still utilizing SVS Infinity Braking for the ultimate in adjustability and distance for all ranges of lures.  

HAGANE
HAGANE is a Shimano reel design concept created to withstand continual use and extreme abuse. HAGANE is an innovation with built-in toughness and durability that works alongside Shimano's precision engineering. HAGANE is for all anglers.

CoreSolid Body
CoreSolid Body integrates the B-Side Plate, levelwind guard and frame into a solid one-piece construction. This delivers an unprecedented feeling of rigidity and sensitivity, and is the first design of this type in a low-profile baitcast reel.

S3D Spool
S3D technology leads to significantly reduced spool vibration. By designing and constructing a balanced and uniform thin-wall aluminum spool, S3D creates an incredibly smooth feeling when casting and retrieving lures.

MGL Spool III
MGL Spool III is the low inertia spool that designed with thin spool wall keeping the durability, This contribute to improve the casting performance, quick response, long distance, cast feeling and castabillity.

S A-RB Baitcasting
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 rotation of the bearing.

X-Ship Baitcasting
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 allows the gears to stay in the same position under the heaviest loads. The added benefit of X-Ship technology is that friction between the spool shaft and gear are eliminated. This further benefits anglers with enhanced casting performance and casting distance of lighter lures.

Cross Carbon Drag Baitcasting
The Cross Carbon Drag material provides a wider range of drag settings compared to traditional drag materials. The Cross Carbon Drag provides the smoothest Shimano drag performance ever while providing anglers with increased durability.
