Shimano reels


Japanese company Shimano for today is one of the world leaders in the market of fishing gear and equipment. Among the assortment of its products the most popular are inertia-free coils, which will be discussed in this article.

The inertial coil is a rather complex mechanism that requires professional approach and quality control at the design and manufacturing stages of the product. The company Shimano constantly improves its products, introduces innovative developments and applies modern high-quality materials. This approach allows us to produce high-quality, reliable, wear-resistant and durable products that faithfully serve the fisherman.

Among the range of inertia-free Shimano coils, you can find very expensive models, and budget. Expensive coil models are mainly used by professionals and advanced beginners, who regularly or periodically participate in fishing competitions. Such models of coils are developed using the latest technologies and concepts of Shimano, thought out to the smallest detail, are made of the most high-quality materials and have excellent technical and operational characteristics, which allows to fully enjoy the fishing process. The cheaper models also have the basic characteristics of expensive coils, which guarantee reliability and high-quality work of the product. However, they are made of cheaper materials and have fewer functional features. This is done in order to reduce the price of the coil while not losing much in its quality.

Today, in the fishing market, there are a number of models of inertia-free Shimano coils, which are in demand among anglers and quite naturally deserve their trust. Let us consider them in more detail.
