This fishing setup employs a collection of small, spinning lures designed to mimic a school of baitfish. The flash and vibration created by the rotating blades, often metallic or brightly colored, attract predatory fish. These lures are typically arranged on a wire or leader with a central weight, allowing them to be retrieved as a cohesive unit, simulating the movement of a bait ball.
The effectiveness of this approach lies in its ability to trigger a feeding response in predatory species. Fish often target bait balls due to their perceived abundance and vulnerability, making this tactic highly effective. The compact presentation allows anglers to cover a wide range of depths and retrieve speeds, increasing the likelihood of attracting strikes. Historically, mimicking the appearance and behavior of baitfish has been a core principle in fishing lure design, and this specific configuration represents a refined application of that principle.
