Overview
Featuring Seaguar’s innovative double structure technology, the Seaguar JDM Grand Max Fluorocarbon Leader has the highest-in-class strength and sensitivity so anglers can detect even the most delicate bites. Designed around the strongest and most advanced Japanese polymers, the GrandMax Fluorocarbon Leader has a hard exterior for increased knot strength and abrasion resistance with a flexible inner core for improved shock resistance.
Available in various sizes for fresh and saltwater fishing applications, each spool is packaged in convenient leader/tippet spools for easy transportation and storage with a built-in connection device to attach multiple spools together. Built to pursue strength, sensitivity, and abrasion resistance, the Seaguar JDM Grand Max Fluorocarbon Leader is a quite limp yet hard leader that’s also one of the stiffest fluorocarbon lines on the market.
