Hi-visibility above - clear below. This monofilament is perfect for flipping, jigging, Carolina rigging and dead sticking – applications where strike-detecting line visibility is essential. TransOptic's clear colour vanishes below the surface. Above the surface and exposed to UV light, it turns bright gold for maximum visibility. Trilene's decades-proven nylon co-polymer formula is abrasion- and shock-resistant and has excellent knot strength. Length: 220 yds.
