## 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.

### ⭐⭐⭐⭐⭐ Abrasion resistance second to none - the best
*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
