Sorensen will offer two seminars at various times throughout the show. One is "Chasing Open Water Lake Trout," and the other is "Ice-Out Multi-Species Action."

When Sorensen says "open water," he's serious.

"It's anything out in Lake Superior more than 10 miles," Sorensen said. "In July, when you get the stable weather, we'll go out 30 to 55 miles offshore."

One week, he might leave from the Ontario shore, the next week from Michigan or Wisconsin, he said. It depends on the wind and weather patterns. He trailers his 22-foot Lund to various launch points.

"We're just looking for structure," he said. "You might be in water 800 to 1,000 feet deep and get a rise from the bottom up 200 feet — or 10 feet. That's going to hold these fish."

At 28, Sorensen has lots of Lake Superior experience. He's been fishing out there since he was 4, he said.

His "Superior Angling" show on WDIO is in its second year and has about 20 episodes remaining in this season's schedule.

Lots to see

As always, the "boat show" will offer a variety of entertainment and attractions for both adults and children. Live duck racing will take place daily. You can fish for live trout at the trout pond. You can talk boats, tour a camper, walk a dock or book a big-game hunting trip. You can buy a gun, learn how to butcher deer, get tips on Lake Michigan fishing and pet British Labs.

The Rocky Mountain Elk Foundation will bring its display of world-class bull elk taxidermy. Fishing tackle and electronics manufacturers will be available to explain the fine points of their wares. Pheasants Forever will have its Youth Village there, with its indoor slingshot, safe archery and BB gun range. Bring your deer antlers and let the Minnesota Official Measurers score them for you.

Go to school

The Lowrance Marine Electronics University returns to the show after its inaugural run last year. Anglers can sign up now to reserve a spot for one of these 1½-hour seminars on touch-screen fish-finders. Cost is $25, and every participant gets a $25 gift certificate upon completion of the course.

Russ Francisco of Marine General Supply in Duluth persuaded show organizers to bring the classes to Duluth.

"We get so many calls from people who buy the (electronics) units and don't read the instruction manuals," Francisco said. "If we can educate 150 people, they'll touch another 150 people. It'll save us phone time."

Every two participants share a touch-screen unit provided by Lowrance, so they're working with the actual device, Francisco said. Five classes (two Friday, two Saturday, one Sunday) of up to 24 participants will be offered. The sessions nearly sold out last year.

To sign up, call Marine General at (218) 724-8833. Sign-up will be available at the show, too, if space is available.

In one change this year, the show will not offer floor shows as it has in past years. Also, the show will close at 9 p.m. instead of 10 p.m. on Wednesday through Friday.
