KatLine™ Fluorescent Braid
High-visibility UHMWPE braid engineered for trophy blues, flatheads and channel cats. The fluorescent finish lights up under UV and blacklight bars for perfect line tracking from boat or bank.
Performance profile
Relative character of this braid vs. standard monofilament — not lab figures.
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.

I have Used This Braid For Years! I catch everything from trophy catfish, alligator gar, bullsharks, and bull reds in saltwater! This line has never let me down or failed! Including trusting it when filming TV shows for history channel! This braid will not let you down!
Great product. Superior fishing line. What ever the conditions are, this line performs as it should. I would recommend this line to any angler. This is the line I trust for tournament competition! I landed my PB BLUECAT 106lbs, in heavy current St Louis MO using 80lb katline.
Great customer service and my items arrived early.
I’ve tried a lot of different fishing lines over the years, and K9 has quickly become one of my favorites. It’s incredibly smooth, casts a long way, and has very little line memory, which makes a huge difference on the water. The abrasion resistance is excellent, and I’ve had no issues fishing around rocks, wood, or heavy cover. Knot strength has been outstanding, and it gives me the confidence to fight big fish without worrying about break-offs. For the quality and performance, it’s an excellent value. I’ll definitely be keeping K9 Fishing Line on my reels and would recommend it to any serious angler.
