Product Details Whisker Seeker High-Viz Monofilament Line gives catfish anglers a tough, dependable mono option for loading 24 reels and targeting flatheads, blues, and channel cats across rocky riverbeds, timber, and submerged structure. Low stretch boosts sensitivity when drifting baits, bumping bottom, or tight lining, and the UV-reactive hi-vis color lights up under blacklight during night setups. Ultra-low memory keeps coils out of the equation, abrasion resistance holds strong around cover, and the 500-yard spool supports both spinning and baitcasting reels for a wide range of bait presentations.
