Simply put, the Calais DC is the best baitcasting reel ever introduced to the market by Shimano. The Digital Control (DC) Circuit stores energy on the cast, only to re-use it in an intelligently applied braking application. The Shimano Calais DC Baitcasting Reel features next-generation 4x8 Digital Control Braking System, 11 S A-RB bearings and High Efficiency Gearing, resulting in the most technologically advanced reel ever. Changing settings on the Shimano Calais DC Reel is simple. Press the Escape Hatch button on the left rear of the reel to fine tune your desired cast setting mode - either X (Extreme Distance), L (Long Distance), A (Accuracy) or W (Wind). Eight different settings on the outside of the Calais DC allow you to further refine the reel's brake application on the water.
