This fluorocarbon from Shimano is part of the Ocea range. This makes it ideal for practical use, although it can also be used in freshwater. With available diameters ranging from 24/100 to over 100/100, you'll be able to cover all the techniques that require its use. Technically speaking, the Japanese brand has adopted the best technology available today, with the superposition of 3 layers offering all its characteristics. The outer layer has been treated to ensure maximum glide in the rings. This not only supports casting distances despite diameters, but also reduces noise. The middle part provides the overall resistance, particularly to abrasion. Rock heads and oyster beds will no longer scare you. Finally, the inner part offers less stiffness than usual, allowing you to tie knots more easily.
