I'm not good at it. plain and simple. I've caught them in day, but a few people can produce time after time. I just cant seem to get the hang of it. But this spring here on my home lake, Smith mtn lake. Really baffled me. Alot of people were catching flatheads during the day, fishing for them and accidently. heard about alot more flats caught then i normaly do. I've tried, just no luck, always ended up catching channels and stripers. Can i ask what are looking for during the day time? I've got to be doing something backwards during the daylight hours. I guess its about time to totaly fish at night for flatheads, atleast on SML the boat traffic gets aweful bad.
