Ideal for searching for trout on the bottom, to be carried out with more or less frequent recoveries and breaks. Trout’s attack can occur in both phases, and is mainly caused by the vibrations produced by the sharp edges of the body. The latter has a relatively high weight, compared to the surface in plan, and its center of gravity is moved forward, for obvious ballistic reasons. Of course, color also plays an important role, and here the range is very rich, with UV solutions that can attract the attention of Trout from far distance or in low light.
