Now, assuming you find yourself while tiny flies hatch and the fish take them in the top 20 cm. of the water column. You can rely on your sight if the light conditions
and the surface rippling allow it. Not easy, but definitely possible. For all those cases with limited visibility, a tiny strike indicator is of great help. It can be mounted in the
following way: on the terminating part of the leader, about 20 cm in front of the fly, insert the leader into a silicone tube 3 mm in diameter, creating a loop. In the nylon loop that protrudes
from the silicone ring, insert a tuft of wool. Pull either end of the leader and the wool will be secured in the sili-ring.
