A high-strength sinking plug that targets tuna, bonito, etc. that chase bait on the surface. After landing on the water, the escaping bait repelled by the flock is completely produced with a horizontal forward fall action. A bait-like slender form with low air resistance that hits an overwhelming flight distance, and a robust ABS resin body and penetrating wire that can withstand long-term fights. It has a particularly high track record in situations where the target is eating up to a dense bait.
