A fishing reel specially designed for freshwater black bass fishing. This is an improved version of the previous Opus-1, which was a general-purpose reel created for a wider range of both saltwater and freshwater fishing. Every part is made using metal that has been treated to be as rustproof as possible, and ion-plated titanium alloy has been used for the rustproof ball bearings, the main shaft, bail, and other parts that require particular durability. The basic specifications follow these requirements for high durability while also taking lightweight construction to the ultimate limit in order to achieve the level of kinematic performance that is demanded in bass fishing. The color of this model was changed to an all-black specification.
