Have a question for everyone. I hear all of you talk about finding fish on your depthfinder holding around cover. I was wondering how you determine if it is a catfish or not and does the cover show up around the fish on the finder. I have a fairly cheap depthfinder and I never know if I should fish based on what the depthfinder tells me. I guess i want to know if you guys use your depthfinders to find individual fish or just fish in general or just mainly for depth and structure. any info is much apreciated.
