Shimano Metanium MGL Baitcaster The Metanium MGL sets the standard for bait casters in the Australian market. This top bait cast model has a strong, durable body made of Magnesium core solid. It's tough and sensitive. The Magnumlite Spool III upgrade reduces spool inertia by 17%. The New SVS system enhances castability and control. It provides a wider brake adjustment range. The main gear of the Micro Module is built from durable brass. Silent Tune tech lessens spool vibration for a smooth reel. The Metanium MGL underwent extensive tests by Shimano for over 12 months. Tests were conducted in Australia's extreme saltwater conditions.
