Keep moving and looking until you find a concentration of walleyes. I could have the best spot where I caught 30 fish the night before and go the next night and not see any fish. Most people I know would just go right on fishing it. They fish memories for two or three hours. I find them.
Walleyes bite extremely light at night.
If always running your bait right on the bottom or through weeds, you d set the hook on everything or become complacent and never set the hook at all. But when you know your bait is running free above most obstructions, the slightest tick brings a solid hookset. It s an instinctive reaction. The rod comes forward even before his brain registers the strike. Good electronics and the first few fish tell you what depth most walleye are holding.
