Overview
Where Seaguar's FP spools are sized for leaders alone, this STS100 line comes on a full 100-yard spool rated at 30 pound test, clear finish.
At 100 yards, listed elsewhere in the data as 300 feet, this spool holds enough fluorocarbon to actually load a reel or tie several leaders off one spool, unlike the 25-yard leader-only spools Seaguar also sells.
- 100-yard spool
- 30 lb test
- Fluorocarbon construction
- Clear finish
Who it's for
Anglers who want to spool a reel entirely in fluorocarbon, or tie several leaders off one spool, get more use from the 100-yard length than a short leader spool would give. Anglers who only need an occasional leader may not need this much line at once.
Strengths and trade-offs
Drawn from this product's published specifications.
- 100-yard length is enough to spool a reel
- 30 lb test suits mid-size freshwater and light saltwater species
- Clear finish keeps visibility low
- No line diameter specified for matching guides or reel capacity
- Lower stretch than mono means a softer hookset is needed
Performance notes
Fluorocarbon like this sinks and stretches less than monofilament, giving more direct feel on the strike but also less forgiveness on a hard hookset, which matters more with a tight drag than a loose one. The 30 lb test puts it in range for mid-size freshwater species and lighter inshore work.
