Shimano Lucanus Flat Fall Jigs are hybrid lures between the original Shimano Lucanus and the Shimano Butterfly Flat Fall jigs. These type of jigs can be simply dropped to the bottom, winded slowly moving the jig through the desired depth, drop to the bottom and repeat. The Shimano Lucanus Flat Fall Jig features a sliding action in a horizontal position, similar to Shimano's Butterfly Flat-Fall jig. This action keeps this jig in the strike zone longer. Fish will often strike on the drop causing a slack in the line.
