Charleston, SC – Shimano North America Fishing, the leading innovator in fishing tackle technology, is thrilled to announce the official release of its highly anticipated Mastiff fluorocarbon line. Designed to meet the demands of bass anglers worldwide, this new addition to Shimano’s lineup makes its debut in the North American market at the ICAST trade show in Orlando, Florida.

“We are delighted to introduce Mastiff fluorocarbon line, designed for serious bass anglers who demand nothing but the best,” said Bob Mahoney, Freshwater Product Marketing Manager of Shimano North America Fishing. “There was no better test of its abrasion resistance, durability, and knot strength than Jeff Gustafson’s 2023 Bassmaster Classic win. He put it through its paces to bring 42 pounds and 7 ounces of Tennessee River smallmouth bass to the stage.”

Mastiff FC represents Shimano’s unwavering commitment to providing the highest quality tackle systems, enabling anglers to conquer new techniques and locations. With low line elongation, even the subtlest of bites will be easily detectable, leading to quick and efficient hooksets. The smooth and supple feel of the product allows for long casts and extreme accuracy even with the lightest of presentations.

In addition to its remarkable performance, Mastiff FC boasts NANOARMOR technology. This extremely fine application of nano-size ridges across the outer surface of the line helps prevent knot-slipping when fighting large fish. This also minimizes slippage and breakage when using common bass angling techniques like twitching, jerking, and casting large lures. With Mastiff FC, anglers will feel connected confidence, knowing that their line is engineered to withstand the rigors of the most demanding situations.
