The hollow, flexible body measures 6 cm, or 9 cm including the appendages. It compresses upon the strike to release the double hook (size 4/0); the entire rig weighs 10.5 g.
Retrieve the line to make the legs flutter, then pause near an opening or the edge of a weed bed. Wait until you feel the fish’s weight on the line before setting the hook, rather than reacting to the splash alone.
