Spinner rigs are deadly weapons for catching walleyes as summer marches on.

These fish-catching combinations of beads, blades and hooks work wonders when you need to cover water hunting for fish scattered along various edges such as depth changes, deep weedlines and transitional areas where different types of bottom meet.

Spinner rigs also excel for fishing other late-summer hotspots such as large feeding flats and weedtops where hungry ’eyes are ambushing prey.

Baiting options vary, but Lindy pro Mike Christensen often prefers a juicy nightcrawler on a two-hook setup like Little Joe’s time-tested Crawler Harness, especially during insect hatches.

When threading a crawler on the hooks, the veteran Mille Lacs Lake guide runs the lead hook through very tip of the nose, so the bait doesn’t spin. Then he rigs the second hook so there is a bow in the harness line, not the nightcrawler.

Many fishermen toss crawlers after the tail gets nipped off by a small perch or walleye, but not Christensen. In fact, he often pinches off part of the posterior himself.

“Trimming the tail releases extra scent into the water, and moves the end of the bait closer to the trailing hook,” he said, noting that both benefits boost your odds of hooking up with more late-summer walleyes on every trip.
