The Thumper mimics the vibrations from striped bass, hybrid striped bass, white bass, sandbass, catfish, perch and other species feeding on baitfish. The vibrations attract fish from the surrounding water and bring them directly to your boat! The Thumper is portable and is used from your boat by connecting to your battery or plugging it into your 12V outlet. The thumper works on aluminum or fiberglass boats including bass boats, bay boats, center consoles, kayaks and pontoon boats!
