Very cheap and proven efficiency. This fishing slider allows you to change the sinker's weight depending on the strength of the tidal stream and lets complete freedom for the fish to take the hook without feeling any resistance. Design : a pacifier tube, two pieces of rubber hose to shock, a clip of your choice, two plastic beads allowing the passage of the tube pacifier and sticked with a drop of cyanoacrylate to prevent them from moving and to tighten the clip so that it will not cut the tube when you will castfish with strength. Time to assembly !
