Berkley Trilene Transoptic Monofilament Line is the first and only nylon monofilament fishing line to physically change color! It’s the line-watchers line. You see the line, the fish don't!
Trilene Transoptic features a proprietary transition technology which is activated by UV light. Transoptic changes from clear to gold in sunlight and overcast conditions. UV light begins to filter out the farther down the water column it goes, causing this line to return to its clear color after a few feet of water depth. This color changing line is the perfect answer for the angler in search of a hi-vis line that won't spook fish.
The following pictures show Trilene Transoptic on spinning reel spool. The clear color picture was taken just after the spool was filled indoors. The gold color picture was taken after 25 seconds of exposure to sunlight.
Berkley Trilene Transoptic Monofilament Line has the durability and abrasion resistance of Trilene XT and the smooth casting qualities of Trilene XL. Its high performance shock strength holds strong under hard hooksets, yet relaxes on the spools of spinning and casting reels.
We stock Berkley Trilene Transoptic in Clear/Gold in 6 to 25 pound tests. All spools are 220 yard.
Line diameters can be seen under the "Specifications" tab above.
