The Fantastic Waggler swim family is one of the most sensitive even among the swims manufactured for competition purposes due to the shape of the float body. The body of the float is balsa wood, with a stem and antenna made of special polycarbonate material. The thin tube of the Fantastic Waggler 1 and 2 floats also promotes sensitivity. The Fantastic Waggler 1 is made for the finest fishing because it has the thinnest replaceable tube antenna, especially recommended for fly fishing.
