Whisker Seeker High-Viz Monofilament Line gives catfish anglers a tough, dependable mono option for loading 2-4 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.Low-stretch mono enhances feel and reduces break-offsUV-reactive hi-vis color improves night-fishing visibilityUltra-low memory prevents tangles and coilingStrong abrasion resistance around rock and structureUV protection shields the line from sun damageSpool length: 500 yd.Test (lb.)Diameter (mm)150.35200.40300.45400.52500.60
