Side-Imaging for the Walleye Crowd


By Joel Nelson, Northland Fishing Tackle
from The Fishing Wire


Walleye-anglers are a traditional bunch in-general.  New techniques and technologies are directly compared to known commodities, and rightly so.  There’s no use making things more difficult than they need to be, yet sometimes along the way what’s learned is in and of itself valuable.  I find that to be especially true in the case of side-imaging electronics for walleye fishing.

So often, structural anglers are used to locating a spot of interest via high definition contours, then picking those locations apart with traditional down-sonar in an effort to locate fish, catch them, and store location (GPS) information in order to return to that spot someday down the road.  Lest we forget, at one time this technology was also new, though its adoption was rapid among the ranks of professionals and casual anglers alike.  Still, I’ve heard it mentioned in even upper echelons of walleye nerdery that side-imaging is only for “bass-guys.”

A staple among tournament bass anglers these days is side-imaging runs that map both structural elements, and individual fish to target.  At last year’s Bassmaster Angler-of-the-Year tournament on Mille Lacs, dozens of complete strangers to the fishery pulled 60lb. bags of smallmouth bass during the 3-day competition, most of them leaning heavily on using their side-imaging to locate large boulders and individual bass off them.  This very application, while being a classic use of the technology, is not a reason to classify it as a “bass-only” benefit.

Shallow water walleyes can be found throughout the warm-water months during big wind events, even in clear water.  That same clarity provides a solid reason to consider side-imaging on your next electronics purchase, as walleyes rarely tolerate overhead boat traffic in clear-water shallows.  The imaging becomes your eyes up shallow, allowing you to stay back off of the fish, and put a multitude of presentations to them without pushing them around and killing the bite.  Shallow fish are typically feeding, so these are the fish you’re looking to target anyway.

While side-imaging proves very valuable for any species relating to shallow structural elements, the same also holds over the depths.  It’s a common misconception that side-imaging isn’t useful at the same depths we’re typically targeting walleyes.  On a recent trip to Grand Rapids, MN, I used my Lowrance Carbon-12 to image an underwater point I’ve fished often, both during open-water and through the ice.  While I knew there was an 8-foot rock-pile along the shallow lip of it, I didn’t give credit to that rockpile and how it affected walleye movements out and away from it.  All of our bites came off the pile some distance in 14-18FOW, as fish staged there before dark awaiting the low-light evening assault on those shallow rocks.  Not surprisingly, immediately out from the pile was a hard-bottom, rock-free shelf.  It was noticeably different from the surrounding break, and drew the majority of those fish.  Once I knew what I was looking for, I could find it on the down-sonar, but it literally jumped out at me on the side-imaging.

An even deeper application can be found on the famed mud flats of Mille Lacs, where savy anglers for many years have known that not all parts of all flats are mud.  There is a surprising amount of rock and gravel in certain locations, though most are in small out of the way places along the edge of the flats.  With a good chop, and the resultant screen display of your sonar showing a “wavy” bottom, it’s difficult to detect the tell-tale signs of rough or un-even rock bottom.  These locations, being different from surrounding substrate for at times, miles, almost always have fish on them or nearby.

Perhaps the best way to introduce yourself to the technology is to image an area you already know, preferably if you know it holds fish.  So often as walleye anglers we stumble onto a mere piece of the puzzle.  We catch fish on one side of a reef for a short period of time in late afternoon, without realizing that we only intercepted fish in a 30 minute window making their way out of the depths and up to structure to feed.  Even if we know fish are likely to be up top and actively eating, we know not what locations have the largest boulders, the most pronounced feeding shelves, or what areas are too weed-choked to effectively fish in low-light.  All of those answers can be gleaned from a quick pass or two around the structure of interest.

Take this technology for a spin on a few locations you’ve fished for years, and be amazed at the depth and level of information it offers you.  Consider it the best real-time map that’s offered today, and get used to seeing and interpreting what information in the plan direction really means to your fishing, rather than just the profile depth direction we’re so used to seeing in the sonar of old.

Garmin Striker Cast GPS Review


Frank Sargeant, Editor
from the Fishing Wire

Garmin Striker Cast GPS—Castable Sonar For the many anglers around the country who fish from shore, piers or docks, it’s always a bit of a mystery how deep the water is within casting range, what structures are on the bottom, and where the fish are in relation to that structure. Without a sonar/GPS screen to tip you off, you’re fishing blind.

Garmin’s Striker Cast GPS puts fish-finding technology into the hands of these anglers, at a very affordable price. It provides quality sonar and GPS on any smart phone.The whole system is encased in a hard plastic housing about the size of a tennis ball. The unit turns on when it’s immersed in water, and links via Bluetooth to your smart-phone once you download the Striker Cast app. You attach the device to your fishing line, cast it out to the water you want to check and presto, a sonar screen appears on the phone.

The Striker Cast is about the size of a tennis ball. It can transmit to your phone from up to 200 feet away.

The device weighs about 3 ounces, so it’s not something you’re going to throw on your light action spinning rod. And it would be easy to pop your line and lose the Striker if you got a dead-stop backlash on a hard cast. I tied it on with 65 pound test Spider Wire braid on the heavy duty snap swivel, just to be sure—that braid will hoist a couple of concrete blocks, so it’s not going anywhere.
Here, a bass hanging over tree limbs on bottom at 8 feet shows clearly. Note the water temperature and depth digital readout on the upper left.

You don’t really cast the Striker—it’s more like lobbing a tennis ball, unless you put it on a 10-foot surf rod. I used a heavy action Shimano Sienna 7-footer and a 4000 size reel that would whip a kingfish, and it was about right.

Manipulating the rod, reel handle and your smart phone all at once is a challenge unless you have three hands. The way I worked it out was to hold the rod in my right hand, the phone in my left and also lightly hold the reel handle. I then rotated rod and reel to retrieve line—it sounds more difficult than it is once you’ve made a few casts.



As with any sonar, the faster the transducer moves, the more the terrain and fish below are compacted, while the slower things move the more they are stretched out. Thus, a foot-long bass going slow under a fixed transducer can look like a 40-pound pike. However, you quickly learn to adjust. The system automatically sets range and gain, or you can adjust both manually at the tap of a virtual scale.

Bottom shows red/yellow, water blue, fish and structure also red if large, yellow if small or scattered. The screen has digital depth and water temperature readouts on the upper left.

The unit also has a very accurate GPS system which allows you to map the area you are graphing. Walk all the way around your favorite pond, casting every 50 feet or so as you go, and it draws a chart of all the water you can reach, complete with depth profiles. You can name and save this, and you can also share it publicly. (I suspect that’s a function not many serious anglers will use!)

The chart was made by repeated casts with the Striker Cast. The opening at the center was where the author walked around a creek, so there’s no graph of that area.

The transducer is not like your boat floating over a fish, which usually flushes anything shallower than 10 feet in most lakes. Fish are not aware of it, and in fact I had a catfish come up and bump it apparently to see how it tasted. So, you can graph an area with a couple casts, spot fish, tie on a lure that gets to their appropriate depth, and hopefully connect.The Striker Cast would also be very useful for ice fishers—it’s compact, easy to carry, and would give you a quick read of what’s happening at each hole you open.

After saltwater use, you’ll want to rinse the connections thoroughly before hooking it up to the included USB charging wire—corrosion is not your friend. I wished the charging LED was a bit easier to see or had an alternate color when fully charged, but that’s a minor inconvenience. The battery lasts 10 hours with a full charge.

Here’s a useful video that teases out the many functions: https://www.youtube.com/watch?v=NEew_HQ90lY.

The Garmin Striker Cast GPS goes for about $180, and it’s sized about right for a stocking stuffer.

Learning Fish Behavior from A Garmin Panoptix

I  have learned a lot from my Garmin Panoptix I installed last November.

This system is a sonar that shows a live picture of what is underwater on the screen, much like shining a spotlight at night shows what is in its beam.  And it shows movement as it happens, not as a line on the screen like older units.

One of my first surprises was how many fish are down there. I see schools of crappie and hybrids and clouds of baitfish suspended over deeper water this time of year.  And I can see fish moving along the bottom, probably catfish and carp.

Fish hovering around stumps, rocks and brush, or holding right on a drop off, are probably bass.


And there are lots of them. But seeing them does not mean they will hit my bait.

Time after time I see my bait move through them and they ignore it. Even worse is when I watch my jig fall on the cast or hop it and see a fish come up to it and follow it back down but never hit it. That does make me change colors, size and baits more often.


When I see fish in brush or on other cover, it makes me make more casts to it. The first tournament I used my Panoptix I saw what looked like fish in a brush pile in front of a dock. Normally i would hit a brush pile two or three times with a bait then move on. But seeing fish in that one made me make multiple casts and I caught a keeper on about my tenth cast!

I have always heard bass move tight to cover in muddy water.  In November and December, Jackson was very clear and I could see bass holding just over rocks and other cover, and they would slowly move around it. But after the rain Jackson muddied up and now I see bright dots indication bass right against the rocks or down in the brush.  And they don’t move, they just sit there.

I know a bait cast out and sinking will swing back toward the boat, and to get it to go straight to the bottom I “feed” line to it as it falls.  That is important when trying to get you bait to the bottom under docks and down to brush.Watching my bait swing back toward the boat as it falls amazes me.  A half ounce jig with a twin curly tail trailer cast on 14-pound fluorocarbon line makes an arch back toward me no matter how much line I feed to it.  It moves back toward me about a foot for every five it falls, so if I cast to a brush pile 20 feet deep I have to cast at least four feet past it to get my bait to hit it.

Another confirmation of fish behavior is the reaction of fish as my boat gets near them. Fish holding over rocks and brush will slowly sink down into it as my boat approaches. In clear water it is very noticeable. Bass over cover 20 feet deep started sinking down into it when my boat got within 30 feet of them.


I saw this happen many times when i moved in to try to jig a spoon or use drop shot. N ow, after seeing it happen, I will try to make very long casts in clear water!

I am just exploring lakes with my Panoptix and hope to learn a lot more in the coming months.

New Technology for Fishing

By David Rainer
Alabama Department of Conservation and Natural Resources
from The Fishing Wire

While perusing social media during this seemingly endless summer, I kept seeing photos of slab crappie that were coming from the Alabama River.Wait, I thought those slabs were caught in the spring when the crappie are spawning or in the fall when the weather and water temperatures have considerably cooled.

Turns out, these anglers were taking advantage of the latest technology to defy the common theory that big crappie are hard to catch during the dog days of summer, which appear set to last into October this year.

I remember well the first Humminbird flasher my late father installed on his boat and how it helped him locate his favorite structure. It was a big deal way back then.Considering we hold far more computer power in our hands when we are using our smartphones than the entire Apollo space program had during their trips to the moon, it shouldn’t be a surprise that the latest fish-finding technology could change the way anglers approach a day on the water.

When I asked Joe Allen Dunn how in the world they were catching those slab crappie, he responded, “You need to come see for yourself.”That’s exactly what happened. While other anglers are using the Humminbird HELIX and Lowrance HDS, Dunn and Brent Crow, a bass-fishing guide and tournament angler on the Tennessee River, opted to go with the Garmin Panoptix with LiveScope.

When Dunn eased his boat into one of the many flats off the main Alabama River at Millers Ferry, I couldn’t imagine crappie of any size would be anywhere but deep water during this oppressive stretch of hot weather.I was wrong, completely. Over went the trolling motor and Dunn began scanning for the structure that are typically crappie havens during cooler weather, or so I thought.Rigged with 16-foot poles and spinning reels, we attached minnows to the double-hook rigs with either bare hooks, jigs with curly-tail plastic baits or Road Runner lures.

We dropped the bait about 8 feet down and started easing toward the structure as Dunn eyed the screen.While I watched the rod tips on my side, Dunn watched the screen as we approached the structure.Suddenly, a rod tip flexed and the hook was set on a nice crappie.On the next approach, Dunn said, “You can even see your minnows, look here.” I looked at the screen and, sure enough, I could see the minnows dangling above the structure.

Then I saw something that I never expected. I saw a swirl in the structure and the fish came up and grabbed the bait. “Holy mackerel” was my response as I set the hook.We started our venture at first light because of the heat and called it a day 4 hours later with 10 nice crappie in the livewell. About twice that many had been caught and released.

“We’ve been trolling for a long time,” Dunn said. “Everybody thinks the slough fish or shallow-water fish are gone or they don’t bite anymore. We proved today that the fish are still there, and they will bite. A lot of people don’t get in the sloughs this time of year and look for structure. Live bait is a big factor until it cools off.”Dunn said before he was introduced to the new technology, the traditional way to catch crappie was to hit the deep river ledges, bouncing baits off the bottom when power production from the dam created current.

“It all revolved around when they were pulling water,” he said. “For river fish, you have to have that moving water. It keeps them tight to the wood, and you can do better.“This new technology is not going to make fish magically appear in front of you. You’ve still got to work to find the fish. The down- and side-imaging helps you locate these fish. But you had to fish so hard to find them.

“Now, I can hit the GPS and mark it. I can drop a buoy and get the boat situated to face into the wind, and then you use the LiveScope to move back and forth on the structure. You don’t have to troll all over the place to find it. It keeps you from disturbing the fish. That’s the key to it. You can keep your bait in the strike zone all the time now.”

Dunn learned about the technology from James “Big Daddy” Lawler, who had been out on crappie guide Gerald Overstreet’s boat equipped with technology.“I’ve been fishing for crappie for 32 years, and I’ve never seen anything like it,” Lawler said. “It’s totally changed the way I look at crappie fishing. I went into Pine Barren Creek and caught fish in 5 feet of water. I never would have believed that.”

Dunn said crappie anglers don’t have to adopt the new technology and will continue to catch fish, but it certainly has changed his thought process.“Used to, we would just give up on these fish when it’s hot,” Dunn said. “We wouldn’t go into these sloughs and work to find them. Now I will.“This is all new to me. Each phase of the season will be a new learning experience. Once the water temperature changes and the fish move around, I’ll have to use this to see where they go.

”Typically, Dunn said when temperatures drop in the fall, crappie anglers are hitting river ledges that are 18 to 20 feet deep. He can’t wait to find out if that pattern is the only way to catch fish when fall finally arrives.“These fish in the sloughs and creeks, I don’t know what they’re going to do,” Dunn said. “They might not even move until it’s time to spawn.

”In the lakes in north Alabama, Crow obviously targets black bass, largemouths and smallmouths.“When you see a fish within 30 feet of the boat, you can see his tail and fins as he swims with LiveScope,” Crow said. “I’ve been running Panoptix and LiveScope for three years. I can’t fish without it. It’s not just seeing fish. It also shows you stumps, grass, drop-offs and ledges. You know exactly where you sit. It eliminates a lot of the guesswork in positioning your boat.

“For suspended fish, it’s just remarkable. I have caught so many fish that I would never have thrown at without it. I would never have had a clue those fish were there. But even at places that are shallow, like Guntersville, it’ll show you the eel grass. You see the edges or isolated clumps of grass. You don’t have to guess.”

Crow said there are limitations for this technology during certain times of the year.“You’re not going to see them if they’re spawning in 3 feet of water,” he said. “Any other time – the summer, winter and fall – it works. At Smith Lake or Lake Martin, you pull up on a point and look with the LiveScope. If there’s not any fish there, you don’t have to spend 15 minutes casting to find that out. You can see it in 30 seconds. It makes you way more efficient.

“You can learn about fish behavior too. They don’t necessarily sit still. You can catch one and see that all the rest of them have moved. Sometimes it’s frustrating because you can watch a fish follow your bait to the boat and never bite. It’s an eye-opening deal. If I get in somebody’s boat that doesn’t have it, I feel like I don’t have a chance. I’m kind of lost.”

Crow said the technology is especially impressive when he’s casting surface lures.“When I’m fishing topwater, you can see your bait on the surface, and then you see the fish come straight up and eat it,” he said. “It’s awesome. When I’m guiding, I’ll watch the client’s bait and see the fish coming. I tell them, ‘He’s fixing to get it.’ They set the hook and say, ‘How’d you know that?’“I had one guy who told me, ‘Don’t tell me that. I jerk too quick.’”

Of course, the new technology is not for everybody. It’s expensive, but that seldom stops anglers. Crow recommends a graph with at least a 9-inch screen, which will cost you about $1,000. The LiveScope tacks on another $1,500. For Crow, he says the benefits far outweigh the cost.Crow said he also found out the technology works in muddy water after a tournament on Toledo Bend on the Louisiana-Texas border.

“The water looked like chocolate milk,” he said. “Every fish I caught during the tournament I saw on the graph. It gives you so much of an advantage over somebody who doesn’t have it, it’s unreal.”

Sad News in the Fishing World

from Lowrance

Darrell J. Lowrance: 1938 – 2019

We are deeply saddened to share news of the passing of Darrell J. Lowrance, founder of the Lowrance brand.

Darrell served as President and CEO of Lowrance Electronics from 1964 to 2006, and was responsible for many breakthroughs in the industry.

In addition to inventing the first recreational sonar product for anglers, the Fish-Lo-K-Tor — known fondly as the “Little Green Box”, he led the development of the first graph recorder, the first integrated sonar/GPS unit, and many others. These innovations form the foundation of today’s Lowrance products and vision.

The first commercial depthfinder from Lowrance

As a leader in the fishing and marine community, Darrell was a member of the Board of Directors for AFTMA (American Fishing Tackle Manufacturers Association – later to become the American Sport fishing Association) from 1978-1986, and again in 1988. He was inducted into the Bass Fishing Hall of Fame in 2013.

“With his passing, the world has lost a great man and a true visionary,” said Leif Ottosson, Navico CEO. “Darrell’s passion for fishing, design, and his dedication to driving the marine electronics industry forward led to innovative ideas and products that have shaped the fishing experiences for millions of anglers globally during the past 60 years.”

In memory of Darrell’s work, many of the competitors at the Knoxville Bassmaster Classic last weekend wore commemorative blue ribbons during Sunday’s final weigh-in.

We mourn this loss and we offer our sincere condolences to Darrell’s wife, Kathleen, and to his family.

Team Lowrance

Fished Germany Creek

On Saturday I fished in Germany Creek where my boat club is located. I sent several hours idling around playing with electronics, working with my Lowrance Carbon side and down scan that I finally got working right. It showed me rocks, brush and stumps on places I have fished for years but did not know were there.

I caught three keepers, one on a crankbait and two on a Carolina Rig. The sunny day had a good many fishermen on the water and some pleasure boaters, too. Clarks Hill is well stocked with stripers and hybrids and that is what most were trying to catch, but there was at least one tournament, too.

Monday was the kind of day I love this time of year. It was cloudy and a little foggy, so everything was muted and quiet. I saw three other boats all day, one of them a group of deer hunters riding to their stands near the lake. It was very peaceful.

Back in the 1970s and 80s I always stayed at the lake Thanksgiving and Christmas holidays, fishing every day. One year I went to my place Christmas afternoon after dinner with my parents and Linda at their house in Dearing. For the next five days I fished every day and never saw another person.

I love it. The only reason I saw someone on the sixth day was I had to go into town and get gas for the boat. The lake is a bit more crowded now, but not too bad.

Again on Monday I spent most of my time on the water studying electronics, marking cover and structure I want to fish later. Some of it I knew about. Some of the brush I marked I put out back in the 1970s. Those cedar trees that stay underwater last a long time, and still hold fish.

I again caught three bass, all on a jig and pig off one ditch. It is similar to places Joshua and I fished on the other side of the lake. Bass like sharp drops this time of year and we used to camp at this place and called it the cliffs, since the ditch runs back and had banks that dropped straight down into the water about ten feet below. Those drops continue underwater, too.
