Lots of research was undertaken by Fiiish in France to develop the unique action of the crazy sand eel, which mimics the swimming action of a live sand eel. The Crazy Sandeel offshore head is the most versatile in the Crazy Sandeel jighead range. It can be fished either in a simple cast-retrieve style, sink and draw or simply vertically. The body is infused with a proven formula and the larger sizes incorporate a rattle to imitate the clatter of small baitfish and allow predators to detect the lure.
