ZFISH Keep Net ECO sight is a sight with a so-called "EKO" net. This type of net is textile and the net is very finely woven so that its meshes are as small as possible. These "ECO" nets are therefore absolutely ideal for storing even the smallest fish, without them accidentally escaping or damaging their fins by so-called snagging o meshes. Necessities such as tightening and arresting cords, a reflective float and a lower plastic eye for possible loading and lowering of the sight to the bottom are already commonplace in our sight today.
