That the EFFZETT® UV-Spinners have only 4 basic colors gives them a kind of hand-made and classic look, but there is one small but important detail that makes these spinners irresistible for every predator. These spinners come with an UV-active feather treble that is very visible for the fish and at the same time the treble is the strike point for the fish, what increases the hookup ration a lot.
