Walleye Pros Crack Code With Humminbird® 360 Imaging™
Epiphany, experimentation and verification with technology results in tournament win
from The Fishing Wire
EUFAULA, Ala. (May 13, 2014) – Water bodies and the fisheries they contain are dynamic systems, changing over time. A good example is famed Minnesota walleye fishery Mille Lacs, which has been the focus of a heated debate over the past several years.
Yet, whatever side of the debate you line up on, one thing is certain, changing fisheries require new and innovative approaches to catching fish.
Case in point, the recent success of tournament walleye anglers Jon Thelen and Mike Christensen, who took first place and lapped the field at the Minnesota Tournament Trail event held on Mille Lacs.
“Since the introduction of zebra mussels into Mille Lacs, the water clarity has steadily increased to eight feet or more. As a result, walleye behavior has changed on many different levels, forcing us to adapt,” says Jon Thelen.
But Thelen is quick to admit that he and Christensen spent four hours during pre-fishing scratching their heads trying to figure out where the fish were.
“Experience told me that given the water temperature and conditions, walleyes should have been sitting on top of rock piles in 17-23 feet of water. But, idling with the big motor over textbook spots on my LakeMaster map and using 2D sonar to find fish, they just weren’t there. I knew there was something strange going on.”
That’s when Thelen and Christensen wondered if the fish were pushing off the structure when they passed over it. “So, I deployed the 360 Imaging unit on my transom and started looking at these same areas without motoring over the top with the big motor. The fish were there clear as day – and right up on top of the rock piles.”
But Thelen didn’t stop there. He wanted proof that the boat was spooking fish off the rocks.
“We experimented with it. I trolled right over the top and we literally watched the walleyes scatter off to the sides – and leave the structure – on the 360 screen. Just proves that you can spook fish over clear, deep waters.”
The rest of the pre-fishing day was spent moving from rock pile to rock pile, looking for fish on 360. If they saw fish, they’d throw out slip bobber rigs, wait for confirmation, and then move on, dropping waypoints on their LakeMaster map for tournament time.
“During pre-fishing, I was able to move the 360 cursor to see exactly how many feet and in what direction the fish were. I like to keep the range at about 100 feet. Unlike the pro bass guys, who are running Bow 360 and moving forward, we may be anchored or positioned sideways in relation to the structure, but because of the directional GPS antenna, I’m able to know exactly where the structure and fish are in relation to my boat and scroll to them. It may be 35 feet off the bow to the right and I know exactly where to cast to those fish – and that’s exactly how we did it.”
From pre-fishing epiphany, experimentation and verification, the team put their findings to the ultimate test a couple days later during the tournament.
“We knew that during the tournament all we had to do was to anchor upwind of these rock piles and throw our floats over the top,” says Thelen.
“When the lake went glass calm on game day, I had a pretty good feeling. We rolled into our first spot and on the second cast we had a keeper in the box. The next two hours we caught a dozen fish, tanked our four fish limit and weighed in by 10:30 a.m.”
Although the fish behavior had changed, the presentation was kept classic: a 1/32-ounce pink and white Lindy jig head tipped with a leech under a Thill slip float.
“Without 360, I never would have been able to verify that the walleyes were sitting up on those rock piles. It saved hours of what may have been fruitless searching.”
At the end of the day, tournament check in hand, Thelen says he learned a valuable lesson running 360 Imaging on Mille Lacs.
“The lake went flat and everybody kept fishing the way they always fish. Could’ve easily been us. It’s undeniable proof that the way we fished just a couple years ago may not work today. Water clarity has increased and fish have gotten spookier. So, you have to adapt. We verified that fish were still on top of the same kind humps we’ve always hunted; we simply had to distance ourselves from the structure and play the stealth game. I know we were the only anglers using 360 Imaging in the tournament and it paid dividends.”
