Highly advanced product, an innovative sinker, pierced and equipped with 2 interchageable poles of different sizes, made of a special plastic material; rigid but at the same time flexible, it will be difficult that it will get stucked.When the sinker arrives on the bottom it will go back faster towards the surface favouring a fast recovery of it.In situation where the bottom presents a lot of asperities it is recommended to use the sinker with wings equipped with the longest pole.Its aerodynamic shape allows a clean fly without producing oscillations; so it is particularly indicated for mixed bottom fishing and for surface fishing techniques.If it is used in high grammages and with the short pole it can be employed for long distances casts with thin rigs.This sinker is supplied with 2 white poles of different colours.
