The Big O is the original square-lip crankbait and sold more than one million lures during its first season of production. It is known as one of fishing's most-copied lures, but no other bait captures that shimmy and produces so many violent strikes. Equally effective in lakes and streams, the Big O truly is one of fishing's most legendary lures. It is one of the most-copied baits in history. Identical fish-catching action and buoyant body. Excellent cover-deflecting ability. Proven performer and timeless design. Great for shallow water fishing. 3 different sizes, weights, depths and hook sizes.
