The Aero Slim Sinker at the tip of gravity gives you an exhilarating cast with a high-flying semi-playing scale. Semi-playable action allows the trimmer to be clearly transmitted to the end of the rod, so even the small trimmer will not miss it. In addition, the joint rolling shaft reduces tangles and thread threads. In addition, the slim sinker not only does it fly, but it also has a little water loud so it wont feel discomfort to fish and sinks quickly in the sea. A convenient new item that makes casting embankment more comfortable.
