Big Indiana Bass: Sonar

August 07, 2016

DI vs 2D Comparison

Once I was able to finally get on the water yesterday, I had a great afternoon fishing with a buddy of mine. I have my boat set up to where I can run as many as 3 sonar units simultaneously, which makes for some interesting side by side comparisons at times. Yesterday was one of those times.

On top, a view of what we were seeing on the 2D - fish stacked tight to the bottom, both on the flat and on the drop.

Next, the DI unit showing the exact same area/spot at the exact same time. Notice how the individual fish stand out a bit better using this view.

What were these fish that we were marking? Crappie!

Final tally for the day as I sat waiting for my buddy to get the truck and ramp out - an action filled day!

Humminbird Screenshot Interpretation

Graph1

I took this Humminbird screenshot Thursday afternoon. The weekend before, I had been out on this same lake and immediately noticed the same thing on the graph, something not normally seen this time of year. I also immediately thought I knew exactly what was going on, as I've seen this happen on this lake and others before. Turned out I was right. Here's the deal.

As you can see, almost all the fish are stacked into the top 12' or so of the water column, especially at the bottom of that band of water. For those that guessed thermocline, you have the right idea, but not quite the right answer. So our waters are definitely starting to heat up as suggested by the 81 degree surface temps, but it is still early in the year in the big scheme of things. Yes, the thermocline is starting to develop, but I don't think many anglers quite fully grasp the entire concept around this. Much of the online bassing sites and articles don't help in this regard.

The thermocline is basically equivalent to the middle layer of the water column, also known as the metalimnion. It is in this layer that you get the quick drop in water temps. Technically, a thermocline is defined as the area of water with the fastest drop in temperature, usually at least 1 degree Celsius per meter, or just over half a degree F per foot. The upper layer of water is the epilimnion, and the lowest layer of water is the hypolimnion. In these two bands of water, the temperature stays relatively stable regardless of depth. As such, the thermocline can be a pretty wide band of the water column, especially early in the year when we are first getting separation of layers. That is what is currently happening on most Indiana reservoirs at the moment.

As the year goes on, that middle layer will get squeezed and become smaller and smaller, and also get pushed to the shallower side. In the screenshot, as on most other Indiana waters, the bottom layer of the thermocline is beginning to form around that 20-25' range. This bottom level of the thermocline, the one most commonly seen on sonar units, is due to the settling of particles, aquatic organisms, and the like. Right now, the top of the thermocline is forming around 10-15' on these same waters. Normally, the warm water fish such as bass, bluegill and catfish will tend to stay near the upper level of the thermocline or shallower, while the cool water fish like trout, stripers, pike and walleye will tend toward the bottom layer of the thermocline. So why are pretty much all the fish in this screenshot staying around that 12'-13' depth band without any being graphed deeper?

160616_0001 The answer is the lake I was on had received an algae treatment about a week and a half ago. As the algae have started to die off and settle, their decomposition has started consuming all the oxygen in the water. To confirm this, I borrowed a YSI ProODO dissolved oxygen meter and went out on the lake to test/confirm this. Sure enough, at the surface, there was 8.75 ppm of oxygen, and the water was about 110% saturated. This oversaturation occurs during the day while the plant life is producing oxygen as part of it's photosynthetic process. It actually puts more oxygen into the water than what that water at the same temperature would hold otherwise. But as we lowered the probe down to about the 10' level, the oxygen dropped to 5.8 ppm and a 71% saturation level.

Slowly, we dropped the probe down a few more feet to the 13.5' level, and the oxygen level continued to dive. At that point we were down to just 1.75 ppm and only 22% saturation. Biologists generally consider 2 ppm as the lower level of oxygen content that can safely sustain fish life for any extended length of time. Once you hit the 15' level, for all intents and purposes, oxygen was gone from the water column. So the reason you don't see any fish pushing further down into the developing thermocline, even though those temperatures are perfectly suitable for fish life, is because they have been stripped of oxygen. This was not the case last year, where at this same time, you could easily find fish down to 20'-22' of water or more.

So the mystery is solved. This exact situation can occur on any of our reservoirs where algae treatments take place. For those who might remember over a decade ago, the initial large treatment at Eagle Creek Res. did the same thing, not only wiping out the oxygen levels to a worse degree than this, but also lead to the death of a lot of fish that were copper sensitive (copper in some form is the active ingredient in many algae applications). That experience, plus a lot of research by local universities, have led to a change in how we now treat these algae outbreaks in most of our state waters.

Behind the TTBC Win: Matt Herren Talks Money Bass Patterns

Humminbird^®/Minn Kota^® pro Matt Herren stays flexible, wins first big tournament in nine years

Racine, WI (May 25, 2016): In the past 14 years Alabama-based BASS Elite pro Matt Herren has qualified for five Bassmaster Classics and six FLW Cups, but hasn’t taken first since the 2007 Wal-Mart FLW Series BP Eastern on Arkansas’ Lake Dardanelle.

“It’s been a grind. I’ve had a string of seconds and thirds. Just wasn’t my time until now,” says the battle-weary Herren.

But everything fell into place for the Alabama-based pro at the 2016 Toyota Texas Bass Classic (TTBC) on Lake Ray Roberts this past weekend, where Herren demonstrated flexibility despite changing water levels and weather conditions. On Day 1 Herren weighed 19-8; 15-0 on Day 2; and 17-4 on Day 3. He edged out second place finisher Bryan Thrift by a mere eight ounces and took home $100,000.

“I won’t lie, it was a tough tournament. It was difficult to stay consistent, which was the key to winning. Guys had 12 and 13 pound days mixed in with 19 pound bags.”

He continues: “Practice was cloudy and windy, and there was a lot of frontal stuff going on. Wasn’t until the afternoon of practice Day 2 that I started figuring out what the bass were doing. We finally got a little sun and that’s when the fish showed up. I had three or four bites that afternoon, and I was really focused on what’s going to happen. I knew conditions were changing rapidly and the key to winning would be staying flexible,” says Herren.

Bark at the Moon

Based on water temperature and moon phase, Herren had a good idea bass would be shallow. In his words, it was simply a matter of figuring out “where, when and how.”

“You’d think May in Texas would have bass in post-spawn and moving out. But we had a full moon, and on the first day of practice the water temperature was 68 degrees, so I knew there would be bluegills and shad spawning; tail-end of the crawfish spawn, too. So, the primary food sources were shallow, despite falling water and everything else. Bass only have two things in their lives that are a must: they’re gonna spawn and they’re gonna eat. Knowing that 90% of their food source is in 10’ or less makes it easy lock in depth zones.”

At that point, the tournament began to set up perfectly for the shallow-water ace. “Everybody thinks shallow is 2’ deep, but to me it’s 15’ to the bank. I love fishing visible patterns like wood and rock. If I can see something and duplicate it, you’re stepping right into my wheelhouse. It’s like being a fast ball hitter standing at the plate – don’t throw me a fast ball ‘cause I’m gonna hit it,” laughs Herren.

Matt on Mapping

But Herren’s visual style of fishing is more than just chunk and winding or flipping to cover.

“When I say ‘see something’ that also means being able to dial in on a particular place or contour on my Humminbird Lakemaster mapping, which could be a certain contour along a channel or whatever. So, it’s visual with my eyes above water, and it’s visual on my mapping. I’m using my mapping all the time, even shallow. I look at contours, breaks, inside turns, outside turns, and all kinds of stuff. The Lakemaster Depth Highlight feature allows me to eliminate 90% of the water on a lake from the get-go, speeding up my pre-fishing a hundred-fold.”

Case in point, how Herren locked in his plan on Lake Ray Roberts.

Photo courtesy of B.A.S.S.

“One of the keys to winning the TTBC was recognizing that the lake was falling drastically. The lake started out 2’ high, but by Day 3 was only 6 inches high, so I had to go into my Humminbird ONIX and HELIX units and adjust the Water Level Offset feature, which redrew the entire map for me. I realized the fish were pulling out of the shallow brush and the willows and into what they call ‘drains’ in Texas—what we’d call creeks everywhere else. The bigger bass started to leave the willows in the 2’-4’ drains and pull out to the 7’-8’ original creekbeds on flats. Lakemaster had every single drain marked, and I could go straight to them, pinpoint the salt cedars, and that’s right where the bigger bass were.”

Developing a Pattern

In terms of developing a pattern, Herren says all he needs is a first bite and a confirmation bite. After that, he studies contours on his HELIX 10 SI GPS, asking himself questions: Is it a main creek? A pocket? Main lake? Then he sets his sights at duplicating those bites by seeking out similar structure, contours and cover.

“Let me put it to you this way: the main difference between pro and college football is the speed of the game. Same thing at the level I fish. Just look at how fast these guys can take one or two bites and turn it into a 20 pound limit. We ask ourselves the ‘why’ questions after every bite. My computer is constantly analyzing information, and I’m using my eyes, my electronics, every tool I have available, and it’s a constant equation, analyzing, calculating, spitting out information to instantly readjust,” says Herren.

Based on his Ray Roberts calculations, that meant employing two primary presentations: flipping 5/8 oz. Santone M-Series jigs and Reactions Innovations Twerk trailers (both in watermelon red) in willows and salt cedars on Day 1 and 2, and running shad-colored PH Custom Lures 2.0 cranks along rip-rap on Day 3.

Boat Control: This Ain’t Russian Roulette

But to make every cast count, he says boat control was critical, especially in the willows and cedars.

“The wind was really pushing the willows around. Add tight quarters and the fact I was I trying to pitch 20’ back into a spot the size of a coffee cup, and boat control really comes into play. All I had to do was tap the Minn Kota Talon foot switch twice and lock that boat down to make absolutely precise presentations. And that’s the difference in catching them or not. This ain’t Russian roulette. Those bass are sitting in specific places, and I’ve got to be able to put my bait right there. Without the Minn Kota Fortrex 112 to put the boat there and the Talon shallow water anchors to lock it down, none of that happens. I typically log about 200 hours on my outboard engine so there’s probably ten times that on my trolling motor at the end of the year. That’s incredible. No internal failures. No cable failures. Nothing. And I’m rough on it. You could plant acres on the fields I’ve tilled up in two feet of water this year.”

Photo courtesy of B.A.S.S.

But it was Herren’s ability to adapt that ultimately won the 2016 TTBC.

“My primary cedar pattern died on Day 3. It got cloudy and the wind changed direction, which really messed with me. But I made the key decision early to go with what was happening and fish some different water. Instead of wasting the morning, I did something else. Turned out a smart decision because I caught 16 pounds by 10 am cranking bridge points.”

While Herren now assumes the TTBC mantle, everyone involved in the Fourth Annual Toyota Texas Bass Classic emerged a winner. Proceeds raised from the TTBC help underwrite Texas Parks & Wildlife Department youth fishing, Community Fishing Lakes (CFL) and other fisheries projects throughout the state. To date, the tournament has donated $2.25 million to the TPWD. To learn more, visit http://www.toyotatexasfest.com/.

KVD’s Comeback: In His Own Words

KVD’s Comeback: In His Own Words

How Humminbird pro Kevin VanDam cracked Toledo Bend’s big bass code

Eufaula, AL (May 17, 2016) - Bass fishing is a lot like any sport. Fall into a slump and critics crawl out of the woodwork. And with today’s multitude of media, there are way too many opinions flying around – most of all the realm of social media, where everyone’s an expert.

But the squawk boxes are it’s a little quieter this week for Kevin VanDam as bass fishing’s icon commanded a wire-to-wire win at the A.R.E. Truck Caps Bassmaster Elite on Louisiana’s Toledo Bend, ending a five-year drought between major wins.

With the world watching, the four-time Bassmaster Classic champion and seven-time AOY weighed a whopping 96-2 four-day total, eclipsing second place by nearly eight pounds. The $100,000 brings VanDam’s career winnings to just shy of $6 million.

For Kevin, this win was personal. It was a long and torturous road filled with late nights, early mornings, miles of travel, and weeks of being away from home. But there was one thing that didn’t change, his Iron-forged perseverance.

We sat down and talked with Kevin about how it all happened and how it feels to be back on top. Here’s a peek inside the boat and the mind of someone who could be angling’s greatest of all-time.

How did you feel going into the event?

KVD: I didn’t know what to expect going into the first day. Practice was really windy, which made it hard to fish offshore, but I got a few bites, so I knew I’d get to fish how I like. I spent a lot of time studying the new Toledo Bend LakeMaster map on my HELIX 10 and just graphing with Side Imaging, Down Imaging and 2D Sonar.

What kind of offshore structure was key?

KVD: Bass were in transition from post-spawn to summer structure, which on Toledo means deeper ledges, humps and spots close to creek channels or the main river channel itself. The water was also really high, so they were pulling some water and the current through the lake moved these bass to outside points. So I tried to find areas like these outside large spawning flats that would hold a large concentration of fish.

What role did mapping play?

KVD: It played a big role. I know the Humminbird LakeMaster guys surveyed Toledo Bend when the water was low and basically destroyed two boats and a bunch of props to get the very best detail possible. That says a lot. So I knew every Humminbird pro was going to have an advantage over the competition. The Toledo Bend map on the new LakeMaster Mid-South States card version 3 is almost overwhelming because there’s so much detail. I fished around Housen in Six Mile, two major creeks in the lower end of the lake, and it was stunning what that map revealed. But it’s the same thing with LakeMaster HD maps everywhere I go, from Kentucky Lake to Guntersville. Sam Rayburn, too. There are no more secrets. For me, it’s actually kind of bittersweet, because now everybody can see the same things that I used to have to work so hard to find. But it’s going to help a lot of anglers become better fishermen.

If you don’t have LakeMaster you’re at a huge disadvantage.

How deep were the bass?

KVD: I had some spots where fish were as shallow as 15’ or as deep as 30’. One of the biggest fish I caught was on a 28’ hump. So, the big thing for me was zooming in and out when I got to these areas. On a 500-foot scale mapping with LakeMaster, you get a great view of everything that’s in the region – how the spot you’re looking at lays out and what’s surrounding it and how fish might funnel to it. But it’s also critical to zoom into the 50-foot scale so you can get the precise line and cast off the ends of these points, especially after I graphed them. Once I had that plot trail I’d use it as a line to make my cast.

Besides mapping, what technologies helped you dial in fish?

KVD: Because there was so much timber and structure, I used a lot of 2D SONAR and Down Imaging in split-screen view. Being able to see both images side-by-side allowed me to discern the different types of fish, was the key. There are so many baitfish, white bass, and yellow bass in Toledo Bend that a critical part is being able to tell what’s what on your electronics.

When they weren’t pulling water, the bass were setting up on or just outside points and ledges and hanging close to the bottom. The white bass were a lot higher up and farther off the drops. The largemouths would be one or two feet off the bottom and I could actually see them on my Humminbird, turn around, make a cast and catch ‘em. And that’s what I found in practice and was able to expand on during the tournament.

Tell us about your winning crankbait program.

KVD: I like to fish crankbaits during post-spawn because I can be very efficient—not only can I cover a lot of water, I can tell the difference between hard and soft bottom. If I’m in 15’ to 20’, I’m going to throw a Strike King 6XD; if I’m in that 19’ to 24’, I like the 8XD; if I’m anywhere from 20’ to 30’ zone, the 10XD is the way to go, especially if you’re trying to target big fish on Toledo. The whole family of baits allows me to cover the 15’ to 30’ zone really well.

I have a cranking system that I worked with Quantum to develop that includes 7’ 10” or 7’ 11” medium-heavy or heavy- action composite cranking rods and my signature 5.3:1 gear ratio reel for power. Depending on the crankbait, I use 12- to 17 lb. fluorocarbon.

Speaking of big fish, tell us about your 8-11 from Day 3.

KVD: I reeled my crankbait down over a hump that topped out at 28’, and I got hung up in brush. As soon as I popped it free that fish bit it. I set the hook, loaded up, and I knew it was a big one. It immediately swam into a tree top, so I just kept pressure on it, eventually getting it to swim out of the tree. Once the fish was inside the boat I was so excited that I jerked the hook out of the fish and into my hand! I had the fish in one hand and had to cull a little pound and half fish and put that big one in the live well with a Strike King 10XD 2/O Mustad treble stuck in my hand. Fortunately, I had a camera guy pretty close and walked him through the procedure for the painless hook removal and it worked like a charm.

Following your win, how do you feel about the rest of the season?

KVD: I’ve had an up and down season to this point. I had a couple good events to start off and was in good shape, but I’ve had a couple really bad days, too, the last at Wheeler. To have a great event here at Toledo Bend, unarguably the best bass lake in the country, really makes it special. I could not have done it without my Humminbird units and LakeMaster mapping. It’s a one-two punch with the Side Imaging, Down Imaging, and the LakeMaster map that is second to none. I’m proud to be with a company that understands the importance of investing in accurate mapping.

Bass Tech Master Class with KVD

KVD shares tech tips to find and catch early-season bass

KVD1 As you’re reading this, bass are in transition, migrating from wintering areas to pre-spawn and spawn habitat, signaling an end to difficult cold-water fishing conditions.

What’s your early-season gameplan? Return to the same spots and do the same things you've done year in, year out? Whether fishing with family, trying to set a new personal best, or working our way up a tournament leaderboard, reducing the time it takes to find and catch fish is paramount. Seldom is that accomplished by a "fishing a memory.” A better approach is to pay close attention to weather and water conditions, adjusting where and how you fish.

This month we discuss the topic with four-time Bassmaster Classic Champion and seven-time AOY Kevin VanDam, a man with an almost machine-like ability to cover water fast, find, and catch bass. A champion on many levels, KVD shares his thoughts on early-season bass and how to utilize electronics that will make for perfect advice for everyone behind the scenes who outfit anglers or rig their rides.

“A lot of people get hung up fishing spots where they caught fish in the past and it’s the wrong time of year, the wrong conditions,” says VanDam. “If I don’t see something positive on a spot in 10 minutes, I’m typically gone. You can’t catch fish there where they’re not. The most important factor in successfully catching fish is finding them. Location is key.”

Q. What can anglers do right now to find early-season bass?

KVD: Monitor the weather, not necessarily the water temperature. Warming or cooling patterns will give you a guideline for what areas of the lake to study ahead of time. Also look at lake topography, which will determine if bass are earlier or later in that spring process than they might be in another body of water. This can help you choose the right lake to fish. Like choosing a shallower lake vs. a deep, clear lake. Shallower, stained waters warm quicker and the fish start that spring process sooner than they do in deep, clear waters.

Q. What are your key early-season presentations?

KVD: This time of year I like techniques that are going to be really efficient for the depth, terrain, cover, and water quality where I’m fishing, so I’m using moving lures: spinnerbaits, jerkbaits, swim jigs, and crankbaits.

Q. What’s the next step after picking a lake?

KVD: I try to think about areas utilized by bigger populations of bass. Spawning areas may be in large bays, large flats, or other shallow water. Look closely at northerly banks, shores or bays. If there’s a cooling pattern I look for structural features that are close to those areas, like a deep break or a channel swing that comes close to a large spawning bay or flat. The predominant sun in the south is going to warm those areas first. And if it’s a full-on warming trend, then bass may be all the way back in those spawning areas.

Turn on your Humminbird and study the LakeMaster chart before you even hit the water. I like to use the Depth Highlight feature. Early-season I’m looking at 10 feet and under. I’ll highlight everything five feet and shallower in red and five to 10 feet in green. That makes the big flats and spawning areas really stick out on your map. And it’s great for highland-type reservoirs like Table Rock or Dale Hollow where the flats are much smaller. If you can find one little flat area and there’s deep water all around that area, boy, that one little stretch can be a goldmine! Depth Highlight makes those areas stand out. Eliminates a lot of searching.

Q. How do you deal with fluctuating water levels this time of year?

KVD: I use Lake Level Offset to adjust the map. If it’s a reservoir that’s drawn down, you can dial in the true depth relationship on your map and then highlight whatever zone you want. I want my map to be as accurate to depth scale as I possibly can. LakeMaster makes it easy. Look at Grand Lake; the Grand Lake Authority has an app that gives you the current lake level right on your phone, so can easily adjust your LakeMaster offset to be current with it. Or adjust it to what you’re seeing consistently on your 2D SONAR.

There’s also the safety issue. Like Florida lakes with treacherous shallow-water areas. Using Lake Level Offset is a simple thing that you can do to make sure your map is spot-on for safe travel. Why guess? You’re crazy not to use Lake Level Offset all the time.

Q. Any other tips for using LakeMaster maps and GPS more efficiently?

KVD: I run my units Course Up; some people prefer North Up. I love the responsiveness of the map and GPS. And the accuracy is a matter of feet! I can put myself right on top of the same brush pile or I can know I’m 30 feet from it to make the perfect cast.

Use the Casting Rings feature, which I worked closely with Humminbird engineers to develop, to help you make perfect casts. Turn on Casting Rings and you now have distance and direction orientation on your LakeMaster map screen anytime you drop a waypoint on a piece of cover, a school of fish, a stump or any other target. This tells me I’m a specified distance from it to make the perfect cast. Again, it’s about efficiency. This is another reason 360 Imaging is awesome. It’s a real-time, updated casting ring that continually shows your position and relationship to the target.

Just making a cast and hitting the ledge with a crankbait is okay, but I’ve found that if I can get a precise distance, so my crankbait releases off the ledge and starts off the bottom toward the boat, bass can be triggered into biting. You have to know your precise distance from that target zone to be able to do that. That’s where the casting rings and 360 really help you.

Q. Are you using AutoChart Live?

KVD: I have and it’s a game-changer. If you go to Kentucky Lake and look at your LakeMaster chip, it’s amazing. But even there, there are places that you could improve on the map. And for anglers in regions of the country with a lot of smaller unmapped waters – like the North – you can now create your own map. For example, my parents live on a small, private lake that hadn’t been mapped. So I used AutoChart Live to make one. But on a lot of the big lakes that I fish tournaments on, you just don’t have time to re-write an entire map. But you dang sure can for certain areas that you’re fishing. So, the next level of mapping accuracy is creating your own maps for areas that haven’t been mapped. And it’s easy to use: basically turn on your Humminbird, hit a button, and fish while it’s mapping and working for you. You can get as extensive as you want, doing transects like LakeMaster surveyors do, or you can go out and just fish and slowly build the map at the pace that you fish those areas. Plus, you’re building it in real-time, right on your HELIX or ONIX. No uploading. That’s the other thing—your data is kept private.

Q. What about SmartStrike?

KVD: Humminbird’s SmartStrike is a great pre-fishing tool. Enter your various criteria like season, weather conditions, etc. and it’ll automatically highlight high-probability areas of the lake to fish. Used to be an ONIX-specific feature, but now it’s available for the HELIX 9, 10 and 12 with a free software update and card purchase, which is amazing. Then, once you get on the water, you can use SmartStrike to narrow it down even more. It’s kind of like having your own guide or local knowledge.

Q. How are you using Side Imaging on a day-to-day basis?

KVD: The depth of the water, type of cover, and structure all determines how I use my Side Imaging. Typically, I have my SI set to look 50 feet left and right in the Amber 2 color palette, which is best for my eyes and helps me read nuances in bottom composition. If I’m looking for isolated large objects, I may got out as far as a 100 feet. The closer the range, the better the detail, the better the target separation, the better you can see individual bass, cover and structural elements. As a general rule, if I’m idling along at 5 mph or less, I’ve got my Side Imaging on to mark brushpiles and other cover. Especially during early-season, I love to Side Image around docks. You can find really interesting pieces of cover: old lawn chairs and other stuff that has blown off of docks, or intentionally-place brushpiles, Christmas trees – all stuff good for holding fish. Side Imaging is probably the most significant development in my fishing career. Instead of just seeing a small area right underneath the boat, you can look off each side.

Q. When are you running 360?

KVD: It really depends on the depth, cover and terrain on the lake where I’m fishing. That determines how much or how little I’ll use 360. If I’m flipping grass mats, I’m probably not going to use it. But if I’m trying to follow an underwater grass line, it’s absolutely critical. Or if I’m in the back of a pocket on a highland reservoir, it can be key for finding brush piles and other cover you might not find otherwise. 360 is another great tool. One HELIX 10 on my bow is dedicated solely to 360, which I’m running a lot of the time.

Q. Walk us through your boat electronics.

KVD: I have four units on my boat: a HELIX 10 and ONIX 10 at the console and two HELIX 12 CHIRP units on the bow, all networked together, so if I drop a waypoint on a brush top on my console unit I can see it on any of my units. That’s a really great feature. You definitely want to have your bow and console unit(s) networked together.

At the console, I have a HELIX 10 dedicated to mapping, which I run in full-screen LakeMaster map or split screen to view a large area and a very focused-in area. The ONIX 10 is used for Side Imaging, Down Imaging and SONAR.

On the bow, one of my HELIX 12 units is used solely for 360 Imaging when I’m on the trolling motor. The other one typically runs SONAR and my LakeMaster map in split screen.

The ONIX 10 SI and DI units have the absolute finest imaging I’ve ever seen. But I fell in love with HELIX for two primary reasons: the flush, flat screen and the improvement in brightness of the actual screen itself. I’m super impressed. I started using them last fall and have to say that in real-world applications the imaging is pretty darn close to ONIX.

The thing that I’m really proud of is the tremendous value that Humminbird has put into the HELIX Series. It is an incredible, detailed and quality picture at an amazing price. It’s an amazing value across the line! It’s incredible. For the features you get, the quality and size of the screen – and the price – it’s amazing.

The other thing is ease of use. There are a lot of anglers who have experience with an 898, 999 or 1199, and the great thing about the HELIX is the menu system is very similar to what we already know.

And just the improvement in the screen as far as visibility and brightness goes. It’s stunning! What I love about the new HELIX is it has the best screen brightness for any light condition – and a simple operating system with all the features that I need with uncompromised reliability. They’re just bullet-proof.

Mine the Spring Bass Motherlode

Insights from BASS Elite Pro Matt Herren

EUFAULA, AL (April 4, 2016) - Spring is in the air, and with it comes the most enjoyable season for fishing. As everything comes alive, hungry bass take note, prowling the shallows in preparation for the spawn. Step one on their list is to eat everything in sight, and bass anglers enjoy taking advantage of the gluttony.

Matt Herren is a tournament champion with a history of high finishes all across the country. A 6-time Bassmaster Classic qualifier, Herren has proven he’s got what it takes to fish in all seasons, coast to coast. His favorite time to fish, though, is during the spring across the mid-south regions of the US, specifically the famous string of reservoirs along the Tennessee River system.

These bass factories, with names like Guntersville, Wheeler and Kentucky, are well-known to bass fishermen around the world for the ability to crank out endless stringers of big bass. With such reputations, one would think that scoring big during the pre-spawn and spawning season would be a breeze. However, through decades of experience, Herren has discovered many understated intricacies that are needed to find the springtime motherlode.

First, it’s important to understand that these bodies of water have vast areas of shallow water, often conducive to springtime staging and spawning, that are unlike those found in most lakes. To further explain, Herren breaks down spawning habitat into two types: typical protected coves and shoreline areas, and offshore areas we’ll call “intermediate ledges.” Like main river ledges—those structures often highlighted in discussions of summertime hotspots—intermediate ledges are flat areas on the edges of submerged creek channels. However, in this case, Herren keys on those ledges that top out at fairly shallow water depths - usually under 8 feet. There, fish interested in spawning can group up and stage prior to moving, or even complete the cycle on the ledge itself.

To start, Herren narrows down his search by selecting areas somewhat protected from current: ledges downstream from major points or other structural elements, or on inside turns of the main channel. However, a quick look at any LakeMaster chip often reveals dozens of areas that match this criteria. How, then, is Herren able to isolate the protective spots?

The key is the efficient use of his electronics. In today’s age of depthfinders that look down, out and all around the boat, Herren has found it necessary to get intimately familiar with such technology in order to stay one step ahead of his competition.

The first and most important step, he says, is to locate areas with hard bottoms. Herren does so by selecting several intermediate ledges that fit his criteria based on lake level, water color and temperature, and graphing with the Side Imaging feature on his Humminbird ONIX. But, rather than do so utilizing the factory default setting, Herren first makes one small, but important, display change. “I always set my unit on Amber 1 color mode” he says. Doing so allows hard-bottomed areas to brightly glow on the screen, easily revealing key spots.

Herren’s user-customization doesn’t end with a quick display change. “I also play with frequency changes (on his depthfinder) a bunch” he points out. Herren has found that the best 2D SONAR frequency setting on his ONIX often changes as he moves from lake to lake. Whether such an oddity is the result of a chemical change in the water, or the amount of small particles floating within, is not totally understood by Herren; he just knows that changing frequency (say, from 83 to 200 kHz) often reveals the best set-up on a day-by-day basis.

Once hard-bottomed areas are located, Herren keeps a careful eye on his water temperature read-out, knowing such plays a major factor in the stage of the spawn. With water temps in the mid-fifties, bass often group up and stage; spawning beginning when the thermometer passes sixty. Herren notes that bass utilizing main lake areas for spawning often do so several weeks after those in protected bays, lengthening the springtime bonanza associated with this season.

Whereas summertime fish will often school on a bare-spot, like a small shellbed, Herren finds springtime fish prefer objects, likely due to these spawning tendencies. “They want to protect their blindside” Herren mentions of the tendency of spawning bass to nest up against and object like a stump or seawall. This behavior applies to open-water areas as much or more to those near the shoreline, as a bit of cover helps bass guard against nest predators.

When a potentially productive area is located through Side Imaging, Herren scrolls across the ONIX screen and marks each with a waypoint. Then, he deploys his trolling motor and utilizes a different electronic approach to investigate the spot, using both 360 Imaging® and Down Imaging.

First, it’s important to understand Herren’s view on each of Humminbird’s technologies. “360 Imaging is a fishing application, not a search tool, ” he says. By this, Herren means that he utilizes 360 only when on the bow and casting, not for idling purposes, as the 360 sweep time is most conducive as a fishing application. In addition, Herren often isolates the sweep of 360 to reveal objects directly in front of him, within casting distance, making the update time on his screen display much quicker. As credit to the effectiveness of this technology, Herren noted that he’s often found new, key areas in spots he’s fished for decades by utilizing 360, opening his eyes to a vast new world.

Side Imaging is Herren’s bread and butter for fine tuning a spot. While he uses the new Humminbird HELIX units primarily for mapping, Herren sticks with ONIX for depthfinding, especially Side Imaging. “There’s nothing like it” he states, adding “I’ve seen things with that unit that I’d never see with any other.”

As Herren fine-tunes a chosen spot on the trolling motor, he’s constantly continuing his search for small, hard-bottomed areas, or isolated objects that could yield a big bass or two. Herren mentions that he often finds fish on the exact same spot, year after year, during the spring season.

Once “on the juice” Herren’s approach to fishing is fairly basic, using an arrangement of tried-and-true springtime lures. “I like a rattlebait a lot, as well as a chatterbait or spinnerbait.” After getting dialed-in to specific pieces of cover, Herren often wields his trademark Santone Jig to mop up on the competition.

But just what makes a good spot great? “It’s a combination of things. Bottom type and cover matter, but maybe so do things like unknown current patterns,” says Herren. It’s a big mystery, it seems, and one Herren admits to constantly trying to better understand. Perhaps we’ll never solve the case, but, with advancements each year in technology, we’re drastically closer all the time.

Humminbird 678DI and Prespawn Crappie

Picked up a Humminbird 678DI unit over the winter and installed it on the boat the previous weekend. Took a couple trips to get the unit and settings dialed in to where I wanted them, but I think I've got things headed in the right direction. Met up with buddy Lee Dilley yesterday afternoon and put the unit to the test. Found a nice tree sitting on the bottom of the river channel in 32 feet of water with a load of crappies hanging around the general area and proceeded to rain some jigs down on their heads. Ended up with around 50+ crappies caught, and a nice limit of fish for the photo op.
