Trout and lots of fishes mostly feed on nymphs and aquatics that live in the water, not on the surface. If you want to angle effectively near the bottom in a deep, powerful stream or river or get deeper in a lake. How do you quickly get the fly down deep? Applying slotted tungsten beads with fishing line is rightly the answer.
Slotted tungsten beads are made of tungsten which is about 70% heavier than lead and is more than twice as heavy than brass. It is also corrosion resistance, so that it can adapt to the sea environment, which is salty. Furthermore, which is more important to us, it is non-toxic. Therefore, using slotted tungsten beads is much friendlier to the environment.
Slotted tungsten beads have high density, which is the reason for fishing hook can go deeper in deep sea or lake, and become more powerful in powerful stream. Slotted tungsten beads are preferred by those who have a tendency to fish in deep sea.
