Fluorocarbon technology has now advanced past the stiff, hard leader to a soft, manageable, easy-casting fishing line. Berkley Vanish refracts light exactly like water does, making it virtually invisible to fish. Berkley Vanish just may make the difference in clear water situations where fish are highly pressured or “line shy”. The first truly fishable fluorocarbon line, Berkley Vanish lays out nicely and casts easily, just like nylon monofilament, making it great for finesse presentations. Berkley Vanish doesn’t absorb water, so it’s able to maintain 100% of its knot and line strength when wet. And its low stretch formula increases sensitivity and handles the most powerful hook sets with outstanding fish fighting power.
