Here's a couple things that I do to try and get those 'sniffers' to bite. Neither works all the time but sometimes they do.1. Try lifting your rod a couple inches, while jigging, then stop it. Keep doing this and sometimes they'll bite. I've had fish that have followed it more than 6 feet up off the bottom before they bit.2. Give your reel handle a real fast crank or 2 and then jig the he$$ out of your lure. I think maybe they think the 'prey' is getting away and it can be a deadly trigger. I've had fish that've been looking at a lure forever come up and clobber it after I do this.
A method I try which sometimes works is to lift your bait about 2 feet fairly rapidly. Then give it a couple of jigs at this depth. Hold your bait still for about two seconds, then SLOWLY lower it down again. Feel for the the bite on the way down, if you feel the slightest "tic".....set the hook! Sometimes Walleyes will just "mouth" the bait and unless your really paying attention you will not feel it.
Does anyone use glow beads or glow hooks when fishing for walleye on tip-ups. I seen some people tie on a Swedish pimple and then put a minnow on that. What are your guys best setup for fishing walleye with tip-ups.
