## 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.

### ⭐⭐⭐⭐⭐ Review
*by E***G on 28 October 2022*

I've used this line for the last 4 months before doing this review . I bought the 12lb spool Its supple enough to tie advanced knots without kinking and tests 12-15lbs under stress In the water, the fluro just disappears But with ANY BRAND fluro , if you fish it in dirty water a few times, its not invisible anymore Very happy and great bang for the buck
