Virtually invisible and proven not to spook fish. Designed to refract light just like water, Berkleys Vanish Fluorocarbon Fishing Line disappears in the water. Vanish Fluorocarbon also maintains its strength when wet, casts well, and is sensitive enough to detect the softest bites. Plus, Vanish offers excellent shock absorbency when you set the hook.
