Seaguar R18 Fluorocarbon Mainline 109yd 7lb Clear – JDM Collection

Overview

Seaguar R18 Fluorocarbon Mainline stands at the forefront of fluorocarbon technology, built to balance strength, suppleness, and castability. This premium line, part of the Seaguar JDM Collection, is crafted for anglers who value crisp casting, smooth line release, and dependable knot performance on a wide range of setups.

Performance in three key areas

• Strength: A double-structure process uses two 100% fluorocarbon resins to enhance knot and tensile performance, giving you confidence when fishing in demanding conditions.

• Castability: The combination of suppleness and design supports smooth, accurate presentation, helping you place precise hooks and lures where you want them.

What you get on each spool

• Test options: Available from 4 to 20 lb, including unique sizes like 5, 7, and 14 lb for specialized setups.
• Color: Clear finish designed to minimize water visibility while maintaining tracking and feel.
