Has any one ever heard of or used a clonk to call catfish? (Clonking). Its an old European tool used to produce a combination of sound and vibration that stirs inactive catfish to investigate and feed. It looks like a big ladle. Yes I know TNT will work too but just heard of this and wondering if its fact or fiction.<br /> http://www.kansasangler.com/archive/0502pro.html
