The Booyah Boo Rig changes the traditional umbrella rig by adding a flexible center lure arm for crankbaits and other lures. The Boo Rig features four stainless steel outer arms with willowleaf blades to produce flas and vibration, but the center lure arm is flexible, allowing anglers to use any lure. Now anglers can throw, using their Booyah Boo Rig, a shallow-running crankbait on their castable umbrella rig and work it on bottom in any depth.
