Opsin Fluorocarbon Line – 4 lb (0.16 mm), 100 YD

Opsin Fluorocarbon 4 lb is perfect for targeting crappie or trout in crystal-clear streams, such as those found in the Sierra Nevadas or other high-altitude waters. Its low visibility and supple design provide optimal bait presentation that won’t spook finicky fish. Strong knot performance means fewer break-offs when that cautious biter finally takes the bait. When the bite is difficult, that’s where Opsin Fluorocarbon stands out—turning subtle nibbles into solid hooksets.
