I saw in another thread that some of you have tried the "Klonk" and with some good success. That is great. I remember that about the time I drifted away from the board, a couple of you guys were given klonks to try. I also recall that it took some practice and learning to achieve that special sound that called the cats in. I lost track of who was trying these and what results you have had. What I really need to know is what brand of catfish respond to it. I know the Wels in Europe and Spain come a runnin. I have read where you guys have called in flatheads here in the US. :0a21:Has anyone had any luck calling in Channels or Blue Cats? The reason for my question is that about the same time we started looking at the Klonk here on the board I came across electronic fish callers that were working very well on shark and tuna. The S2 Instrument folks were developing calls for other fish and what they told me was that a catfish call was underway. I went back to check on it last night and to my surprise there is a call on the market. From what I could read it is the Klonk sound reproduced electronically or with a recording. I might be interested if it calls channels and blues as well as flatheads.
