The Whisker Seeker High-Vis Monofilament Line - 1 Lb. Spool gives catfish anglers a tough, dependable mono option for chasing flatheads, blues, and channel cats across rocky riverbeds, timber, and submerged structure. Low stretch boosts feel when drifting cut bait, bumping bottom through current seams, or tight lining on anchor, while the UV-reactive hi-vis color lights up under a blacklight during night setups. Ultra-low memory prevents coils during spool-up, abrasion resistance keeps the line intact around cover, and the smooth diameter supports spinning and baitcasting reels across a wide range of presentations.Low stretch improves sensitivity for drifting, bumping, and tight liningUV-reactive hi-vis color aids nighttime visibility under blacklightUltra-low memory reduces tangles and improves handlingAbrasion resistance holds strong around rocky structures and timberTest (lb.)Diameter (mm)Spool size (yd.)200.402,500300.452,030400.521,600
