Seaguar STS Trout & Steelhead Fluorocarbon - 100 Yards When the water runs clear and the fish run smart, your line choice makes all the difference. Seaguar STS is purpose-built for trout and steelhead anglers who demand near-invisible presentation without sacrificing strength. Tied to a size 12 hook in a gin-clear river or drifted through a coastal run, STS disappears - so all the fish sees is the bait. Key Features 100% Fluorocarbon - refracts light like water for near-invisible presentation Superior knot & tensile strength - holds up through hard strikes and long fights Low memory & high sensitivity - casts smoothly and transmits bites clearly Abrasion resistant - handles rocky riverbeds, structure, and current Sinks faster than mono - ideal for drift fishing, nymphing, and finesse presentations 100-yard spool - enough for multiple re-spools or leader material Specifications SKU Test (lb) Length 04STS100 4 lb 100 yds 06STS100 6 lb 100 yds 08STS100 8 lb 100 yds 10STS100 10 lb 100 yds 12STS100 12 lb 100 yds 15STS100 15 lb 100 yds Best For Trout fishing in clear streams and lakes, steelhead drift fishing, salmon leader material, and any finesse freshwater application where line visibility is a concern.
