The Metanium DC is Shimano's flagship baitcasting reel. In addition to its impressive quality bearings (9+1), it benefits from numerous technologies such as the X-Ship, a Hagane frame, MicroModule gears and an S3D spool.
As for its drag, it is equipped with the famous I-DC5 digital control system: a microchip calculates at a rate of 1000x per second the exact power of the spool drag during casting. So, all the angler has to do is to make a pre-setting (enter the type of lure and line) and the reel takes care of the rest! Results: the Metanium DC is very easy to use, it allows to cast far, while limiting the wigging or problems with wind or other difficult conditions.
