Color availability reflects current stock and may vary — see the selector above. Rigging notes Terminal: Palomar, Uni or San Diego Jam; FG for leader connections. Pair with a 40–80 lb mono/fluoro leader for shock absorption near the hook. Fill spools to ~1/16" below the lip to maximize casting without overruns. Field notes Run a UV/blacklight bar at night to watch bow, slack and crossovers in multi-rod spreads. Inspect the first 6–8 ft often; trim back after snags. In heavy current, step up one test to cover sinker load and abrasion. Also excels for stripers, musky and gar. Frequently asked questions Does KatLine glow under a blacklight?Yes. The fluorescent finish is UV-reactive and becomes highly visible under common catfishing blacklight bars, making night line control dramatically easier.What pound test should I choose?60 lb covers channels and all-around spreads, 80 lb steps up for heavy current and big timber, and 100 lb is the trophy blue/flathead choice around brutal structure.Should I run a leader?Often yes — a 40–80 lb mono or fluoro leader adds shock absorption, abrasion protection near structure, and an easy break-point to free snags. Complete the system Pair KatLine mainline with a KatLeader section for maximum abrasion and shock protection.
