## Overview

Seaguar STS Trout/Steelhead Fluorocarbon Leader is a premium 100% fluorocarbon fishing line designed for freshwater anglers targeting trout and steelhead. It features a 10-pound breaking strength, superior abrasion resistance, and a fast-sinking profile that places bait quickly in the strike zone.

## Description

Seaguar, the inventor and world leader in fluorocarbon and premium fishing line, has introduced STS, its first species-specific fluorocarbon leader material targeting Salmon, Trout and Steelhead. STS is 100% fluorocarbon leader material that delivers incredible abrasion resistance and maximum impact and knot strength, all with a smaller line diameter than monofilament. This fast-sinking line gets you in the "strike zone" quicker - and with a lower refractive index than monofilament line, it is significantly less visible underwater.

## Questions & Answers

**Q: I need stiff leader material for hoochies behind a flasher - is this material stiff and well suited for a hoochie leader?**
A: Plenty stiff and knots a lot better than the blue and is literally 1/4 the price

**Q: Whats a good test pound leader for #20 and #30 brain main line?**
A: I have had problems with light line.  I would stay with at least #20, STS is brittle.  I stick with maxima, it’s more visible at #10, but loses much less fish.  It’s the choice between a few more hookups, but you will lose more fish on STS since it is brittle, especially with braid mainline.  Take a piece of the STS and try to break it with an overhand knot to test it before you use it.  At #10 my 5 year old could break it with his hands, so I never used it again..

**Q: What is the line diameter for 6lb?**
A: .008 inches

**Q: What diameter is the 12 pound test?**
A: .31 mm is the diameter of 12 pound test STS Trout and Seelhead.

### ⭐⭐⭐⭐⭐ Highly Recommend
*by C***Y on January 8, 2026*

Bought the 15lb. for fly fishing leader tippet...using for Puget Sound coho salmon. These fish average perhaps 5-6 lbs. and are not particularly leader shy. It's was my first fluorocarbon purchase. I came to love the stuff for how abrasion resistant it is and how it's practically invisible in water. I've since purchase all other sizes from 4lb to 25lb and build all my sinking tapered leaders (keep in mind fluoro sinks more readily than monofilament) with it for many species and fly types. It has never failed me...which is pretty freakin' amazing.
