The Shimano Metanium Baitcasting Reels are designed for the avid fisherman and tournament bass angler. These low profile baitcasting reels are all about lightweight versatile performance. They feature a micro module gear system that creates a smooth retrieve. This allows for a more efficient gear train with less gear feel. These reels also feature SVS Infinity, Shimano's newest brake system technology. This provides easy to manage and consistent spool control and brake force.
