The Pro-Model Jig has a new head design and a unique new rattle design. Both enhance performance in heavy cover. The wide rattle has one big open chamber that enables the rattle to work even when the jig moves to the side. It is positioned to the front of the hook shank, higher off of it and has a barb, all of which make it easier to rig and to hold onto soft plastic and ElaZtech™ soft bait trailers. A larger, more premium Mustad® Ultra Point Hook is used. Premium camo-flash skirts enhance the colors. The Pro-Model® Jig is truly a top-of-the line jig.
