I am probably worse at catching winter eyes. Summer, Spring and Fall I am not very good at either. That said, I have caught an okay amount and have caught many from tips on these forums over the years. One thing about walleye for inland waters, people are a bit tight lipped compared to other species. Use the search function and I would bet that you will find a lot of techniques guys use. Whether they will work for you, who knows. I say that, as I have used, to my best ability and nothing.
Someone that knows what they are doing, changes something minor that I am doing wrong likely limits out standing next to me! Best bet is to try to gather as much as you can and keep trying. God is good, he’ll throw you a bone every so often to help figure things out!
From what I know about winter, many are deep, where water is more in the temps they like. Also where the bait is more comfortable. Or, where the bait is dying and easy pickings. I have tried it a bunch of times and nothing for my efforts. I don’t mind trying to put time in and figure out when not freezing my rear off. But winter fishing, has to have some sort of catching or just not worth it for me.
