Floating marker designed to find fishing spots on the seabed. It is white for easy identification from the surface. The 30-meter-long white 1.5 mm line guides the diver to the seabed to the place where he left the lead anchor. The central floating bouy, once free, goes up to the surface. It also has a hook and some useful cuts on the sides to lock the line, preventing it from continuing to unfold. Once the line is locked under the surface, it stays vertically on the point at the bottom. It is equipped with a 250 gram rubberized lead to minimize sound as it reaches the bottom. The elastic band has a tear-off strap that allows it to be applied to the belt without having to remove lead.
