For more action and bite, the Black Cat Catfish Clonk is unbeatable. The vibrations caused by this clonk will attract the attention of catfish in every layer of water. The Shallow Water variant is excellent for calm water with a depth of up to 6 meters thanks to the relatively quieter pressure waves. The Deep Water variant causes very strong and far reaching pressure waves which makes it perfect for deeper water from 5 to 20 meters.
