Side imaging fish finders project sonar beams out to port and starboard from a single hull-mounted transducer, painting brush piles, rock ledges and baitfish as bright returns and shadows on coloured bands either side of a black depth channel. That picture lets a bass boat read an entire flat without running over it, which is why the best side imaging fish finders for bass boats are the first piece of electronics most tournament rigs are built around. We compared 10 of them for this guide.
The argument for side scan over forward-facing sonar comes down to what each one is for. Forward-facing sonar shows you a fish and a lure in real time at close range, which is a presentation tool. Side scan covers 100 to 200 feet of water per pass, which is a search tool. Anglers run the search first, mark the structure, then switch to a bow unit or down riggers for the close work.
Getting that picture reliably depends on the transducer, not just the screen. Height, angle and hull speed change how clean the image looks, and shallow water collapses range fast. Our picks below account for all three, and the table further down lines up every unit side by side.
If you are still building out an electronics package from scratch, our broader fish finder roundup covers portable, ice and boat-mounted options outside this list. For cheaper setups, see our picks for fish finders under 500 dollars.

How We Picked the Best Side Imaging Fish Finders for Bass Boats
Every unit here was judged against the same six criteria, chosen for what actually decides whether a bass angler can use side scan on the water.
Range per side at readable quality. Advertised maximums are marketing; we weighted the number of feet where detail still holds together at cruise speed.
Image clarity. Target separation on baitfish and the crispness of the shadow behind a brush pile.
Install effort. What the package needs in the hull and at the console, and whether the transducer cable reaches.
Mapping path. Built-in charting, custom contour mapping and how well the unit shares data with a phone or a second screen.
Shallow water behaviour. How the image holds up when you are working a flooded creek at three feet.
Owner feedback. Long-term reports on brightness, software stability and support, not just first impressions.
Two rules were non-negotiable. Every unit here must carry side imaging hardware, either in the box or as a clearly flagged transducer variant, because a control head that only shows CHIRP cannot do the job this guide is about. And every screen we considered sits between five and ten inches, since a console on a bass boat has a finite dash width.
1. Garmin STRIKER 7SV: The Best Side Imaging Fish Finder Overall
Garmin Striker 7SV with Transducer, 7″ GPS Fishfinder with Chirp Traditional, ClearVu and SideVu Scanning Sonar Transducer and Built in Quickdraw Contours Mapping Software, 7 inches (010-01874-00)
7-inch color TFT
SideVu and CHIRP ClearVu sonar
Quickdraw Contours
Wi-Fi with ActiveCaptain app
Pros
- Clear and effective SideVu imagery for spotting structure
- Bright sunlight-readable 7-inch display
- Quickdraw Contours builds 1-foot maps as you run
- Transom and trolling motor mounts in the box
- Easy to install and simple to operate
Cons
- No chartplotter so charts need a separate device or phone
- Side scan is sensitive to transducer height and angle
- ActiveCaptain navigation is awkward in bright sun
This is the unit we kept reaching for during testing. The SideVu picture is crisp enough that isolated stumps and small brush piles separate from the background without cranking the gain, which matters on water where you have three hundred feet of ledge to cover before the next spot.
Quickdraw Contours is the underrated part. It records your depth as you run and turns it into 1-foot contour lines you save and reload, so the third trip to an unfamiliar lake starts with a map instead of a guess. Owners report a noticeable lift in catch rates once they stop idling over structure they already know.
The package is complete for a trolling motor install. The CV52HW-TM transducer, a 4-pin to 12-pin adapter cable, transom and trolling motor mounts and a tilt/swivel bracket all come in the box, and the whole head weighs 1.7 pounds.
What you give up is mapping. There is no chartplotter here, so charts come from the ActiveCaptain app on your phone or a separate display. Reviewers also note that side-scan output is sensitive to how the transducer is mounted and that a few boxes showed artifacts before the unit was re-mounted properly.
Who the Garmin STRIKER 7SV side imaging fish finder suits
This is the right pick for a single-screen bass boat that needs good side scan without a permanent console refit. It bolts to a trolling motor shaft or transom in an afternoon, and the brightness holds up on a bright lake at noon.
It is also the practical choice if you fish primarily for brush piles, stumps and creek channels rather than running deep offshore ledges. Thirty to eighty feet to each side is where this unit is at its most confident.
Where the Garmin STRIKER 7SV side imaging fish finder falls short
If your boat already has a chartplotter, this unit is redundant on that front. It also cannot be split into three panes usefully at seven inches, so running side scan alongside a chart means squinting at two small panes.
Owners who fish tight to banks and in heavy wind report more shadowing and false returns than they expected. Proper mounting height fixes most of it, but it is a real consideration before you buy.
2. Lowrance Elite FS 10: The Best All-Around Side Imaging Fish Finder for Bass Boats
Lowrance Elite FS 9 Fish Finder with Active Imaging 3-in-1 Transducer, Preloaded C-MAP Contour+ Charts
10-inch touchscreen
3-in-1 CHIRP SideScan and DownScan
C-MAP DISCOVER charts
2-year warranty
Pros
- CHIRP SideScan and DownScan plus 2D sonar from one 3-in-1 transducer
- Large 10-inch touchscreen shows sonar and charts together
- C-MAP DISCOVER charts cover inland coastal and Canadian waters
- Wireless NMEA 2000 and Ethernet networking for bow to stern
- Live sonar upgrade path when you are ready
Cons
- ActiveTarget 2 live sonar is a separate purchase
- Touchscreen controls take practice while running
- 10-inch and larger sizes push cost above entry level
Side scan is only half the story on this one. The same 3-in-1 transducer gives you CHIRP down imaging and traditional 2D at the same time, so a single pane handles the whole picture while you work a grass edge.
The 10-inch touchscreen is the real advantage on a bass boat console. Split it two ways for chart plus side scan and both stay legible without leaning in, which is exactly what you want at 60 miles per hour.
C-MAP DISCOVER charts load as standard, covering inland, coastal and Canadian water, so the unit works as a chartplotter out of the box. Wireless, NMEA 2000 and Ethernet connectivity let you mirror or link to a bow unit later.
Anglers describe it as fishable on factory settings, which is more than can be said for several competitors. The catch is that live sonar needs an ActiveTarget 2 module bought separately, and the menus need a few trips to learn.
Who the Lowrance Elite FS side imaging fish finder suits
Pick this one if you want one screen to do everything and you would rather not maintain a separate mapping head. It suits a solo angler running a single console who covers a lot of water and wants charts without a subscription.
It also fits multi-screen plans well, since the networking is standard rather than an add-on. Start with this at the console and add a forward-facing unit at the bow when the budget allows.
Where the Lowrance Elite FS side imaging fish finder falls short
A 10-inch screen needs real dash space. On a smaller bass boat console you may be cutting into a moulded panel that was not designed for a head this size.
Side scan image quality on Lowrance has improved a great deal, but longtime anglers still rank Humminbird higher for raw picture detail in the same price band. Touchscreens also misbehave with wet hands, and this is a capacitive panel.
3. Humminbird HELIX 7 CHIRP SI GPS G4: Best Premium Side Imaging Fish Finder Pick
Humminbird 411590-1 Helix 7 Chirp SI GPS G4
7-inch color TFT
CHIRP Side and Down Imaging
Dual Spectrum CHIRP
Basemap over 10,000 lakes
Pros
- CHIRP side imaging filters clutter for a cleaner look beside the boat
- Bright screen readable in direct sunlight
- Dual Spectrum gives wide coverage and narrow detail modes
- Transom transducer and gimbal bracket included
- AutoChart Live builds your own contour maps
Cons
- Settings and menus take real practice to learn
- Range per side is shorter than MEGA Side Imaging models
- Side imaging range drops fast in shallow water
This is the unit we trust most in the category it occupies. CHIRP Side Imaging filters noise that cheaper units pass straight through, and the result is a cleaner image when you are running a flooded timber edge at speed.
AutoChart Live with eight hours of built-in recording time means you can map a lake across a weekend and still have recording space left. Owners who fish new water weekly tend to come back to Humminbird mapping first for a reason.
Humminbird Basemap covers more than 10,000 lakes plus US coastal water, and the unit accepts LakeMaster, CoastMaster and Navionics cards if you want more detail. Internal GPS handles waypoints and routes without another box.
The trade-off is range. Standard CHIRP side imaging here does not reach as far as MEGA Side Imaging models, and the menu system asks more of a first-time user than the Garmin and Lowrance interfaces do.
Who the Humminbird HELIX 7 side imaging fish finder suits
It fits anglers who fish lakes they do not know and intend to learn them. Mapping quality and side scan detail are both a step above what you get at the same tier elsewhere.
Smallmouth anglers in particular tend to land here, because the clearer return helps them separate stumps from rock in stained water where the usual picture turns to mush.
Where the Humminbird HELIX 7 side imaging fish finder falls short
Range is the honest limitation. If you need to sweep a deep lake from one pass, this is not the head for the job and the XPLORE or a MEGA Side Imaging model is the better answer.
The keypad and softkey menus are dated next to a touchscreen, and buying open-box from a marketplace seller instead of an authorised dealer can complicate warranty service when something fails.
4. Garmin STRIKER Plus 7sv: Best Side Imaging Fish Finder for a Quick Install
Garmin STRIKER Plus 7sv with CV52HW-TM Transducer and Protective Cover, 7 inches 010-01874-00
7-inch color TFT
SideVu plus CHIRP ClearVu sonar
Quickdraw Contours
Cover included
Pros
- Clear bright screen readable in direct sun
- SideVu paired with traditional and ClearVu sonar
- Quickdraw Contours builds custom maps on unmapped water
- Straightforward setup and operation
- Protective cover included in the box
Cons
- No chartplotter so a separate mapping display is needed
- Screen glare shows in harsh midday sun
- Reading the manual is needed to get full value from the features
This is the same SideVu platform as our top pick, packaged as a transom-ready kit with a protective cover. That cover matters on a bass boat, because the console sits in sun all day and seven inches of bare screen gets hot and scratched.
Side scan output is genuinely effective for finding structure, and pairing SideVu with CHIRP ClearVu means you can watch a brush pile from beside and beneath at once without switching modes.
Quickdraw Contours does the same job as on the STRIKER 7SV: record depth as you run, save it, reload it next trip. For an angler breaking down a new lake without a mapping subscription, that is the whole value proposition.
Owners like the crisp display and the simple setup. The recurring complaints are glare in direct sun and the absence of built-in charts, which pushes navigation to a phone or a second unit.
Who the Garmin STRIKER Plus 7sv side imaging fish finder suits
It suits anyone who wants the top pick in a package that can go straight onto a trolling motor or transom. Owners consistently describe installation and setup as simple.
It also works as a portable unit. Anglers who move between a bass boat and a jon boat commonly carry this head and the transducer with them.
Where the Garmin STRIKER Plus 7sv side imaging fish finder falls short
It is a fish finder, not a chartplotter. Anyone who navigates unfamiliar water seriously will want charts on the same screen, and this cannot do it.
At seven inches you cannot usefully run three panes, so side scan plus chart plus down imaging means squinting. For older anglers the small screen is a genuine strain after a full day.
5. Humminbird XPLORE 10: Best Side Imaging Fish Finder for Long Range per Side
Humminbird XPLORE 10 GPS Fish Finder with Transducer, MEGA Side Imaging+ & HD Touchscreen
10-inch HD touchscreen
MEGA Side Imaging+ 200 ft per side
MEGA Down Imaging+
3-year warranty
Pros
- MEGA Side Imaging+ covers 200 feet to each side
- Large improvement in resolution and brightness over older Humminbird heads
- Touchscreen with favorites and customisable panes
- NMEA 2000 Bluetooth and Ethernet networking
- Includes a LakeMaster VX map card
Cons
- Steep learning curve for first-time Humminbird users
- Included coastal chart detail is thin in some near-shore areas
- Older non-NMEA 2000 sensors will not work
- 9-inch model feels cramped when panes are split
Two hundred feet to each side is the headline number, and in practice it holds up on deep, open water where there is nothing to reflect off but bottom and structure. That is exactly the situation on a big reservoir ledge fish.
The display is the other story. Owners moving up from older Humminbird heads describe the jump in resolution and brightness as night and day, and the touchscreen with favourites is far faster than working through hard buttons.
Networking is genuinely complete: NMEA 2000, Bluetooth, high-speed Ethernet, plus direct integration with Minn Kota trolling motors and Cannon products. A LakeMaster VX card for US and Canadian regions is included.
AutoChart Live maps depth contours, bottom hardness and vegetation with eight hours of recording time built in, which is why forum anglers still call Humminbird mapping the gold standard for self-made charts.
Who the Humminbird XPLORE side imaging fish finder suits
This suits an angler who runs open water and wants to cover a whole ledge system in one pass rather than three. It also fits a boat already wired for one-boat network integration.
If you own a Minn Kota trolling motor, the built-in integration removes most of the networking friction that trips people up with mixed-brand rigs.
Where the Humminbird XPLORE side imaging fish finder falls short
The learning curve is real. Owners upgrading from older units love it, and new users describe the setup as demanding, with a manual that omits some steps including how to seat a Zero Line SD card at boot.
Reliability is the other question mark. Forum discussion of Humminbird hardware runs warm on side scan quality and cool on failure rates, so support through an authorised dealer matters more here than with the others.
6. Humminbird HELIX 7 G4 MEGA SI: Best Side Imaging Fish Finder for Shallow Cover
Humminbird Helix 7 G4 GPS Fish Finder with Transducer, MEGA Side Imaging
7-inch color TFT
MEGA Side Imaging 125 ft per side
MEGA Down Imaging
Transducer included
Pros
- 125 feet of coverage to each side with three times the detail of standard imaging
- Transducer included in the box
- Bright 7-inch display with softkey controls that work in any weather
- AutoChart Live maps contours bottom hardness and vegetation
- Dual Spectrum CHIRP separates arches from structure
Cons
- Seven-inch screen is compact against 9 and 10-inch units
- Premium chart cards are a separate purchase
- Keypad menus take practice to master
MEGA Side Imaging at 125 feet per side is a bigger claim than the standard CHIRP side scan on our third pick, and the extra detail is what keeps brush piles readable in stained water. This is the head we would mount on a boat that lives in a creek-heavy lake.
Dual Spectrum CHIRP gives you a wide mode for coverage and a narrow mode for detail, which matters when you are deciding between a stump and a rock at 90 feet.
The keypad is an advantage, not a compromise. Softkeys work with wet hands, in rain and while wearing gloves, and that is worth more on a fishing boat than a touchscreen is on a desk.
Who the Humminbird HELIX 7 MEGA SI side imaging fish finder suits
It suits anglers who want more side scan reach than a basic CHIRP unit without stepping up to the XPLORE tier. The transducer is in the box, which removes the most common install mistake.
It is also a good bow unit on a multi-screen boat, giving the front of the boat side scan detail while a chartplotter stays at the console.
Where the Humminbird HELIX 7 MEGA SI side imaging fish finder falls short
Range per side is half what the XPLORE offers, and detail drops off faster in the shallows. On water under ten feet you are reading structure at close range whether this unit is on the console or not.
Serious mapping requires a LakeMaster, CoastMaster or Navionics card on top of the base map, and seven inches is cramped once you are splitting panes.
7. Lowrance HDS PRO 10: Best Side Imaging Fish Finder for Large Consoles
Lowrance HDS PRO 9 Fish Finder with Active Imaging HD 3-in-1 & C-MAP
10-inch SolarMAX HD touchscreen
Active Imaging HD SideScan
C-MAP DISCOVER
Ethernet and wireless
Pros
- High-definition SideScan and DownScan from the included 3-in-1 transducer
- SolarMAX HD screen visible at wide angles and through polarised lenses
- C-MAP DISCOVER charts preloaded for US and Canadian waters
- Ethernet NMEA 2000 wireless and Bluetooth connectivity
- Available in 9 10 12 and 16-inch sizes
Cons
- Highest cost in this group with the lowest average rating
- Live sonar hardware sold separately
- Setup and configuration take more effort than simpler heads
Active Imaging HD raises the resolution of the SideScan and DownScan channels, and on a SolarMAX HD panel the return stays visible at wide viewing angles. If your console sits under a hardtop with shade across the dash, that matters.
The 9, 10, 12 and 16-inch options are unusual in this category. A bass boat rigged for a triple-screen layout can order matched panels, which is the one configuration competitors mostly cannot offer.
Connectivity is exhaustive: Ethernet, NMEA 2000, wireless and Bluetooth, with radar and trolling motor integration. C-MAP DISCOVER charts cover US and Canadian inland and coastal water from the box.
The honest drawback is that this group carries the lowest average rating and the smallest review pool. Owners who have it like it, and the complaints are about value against the Elite FS rather than about the picture.
Who the Lowrance HDS PRO side imaging fish finder suits
It suits a larger console or a multi-panel layout where screen real estate is the constraint. Polarised sunglasses wearers get a real benefit from the display optics.
Anyone already running Lowrance elsewhere on the boat can keep one ecosystem across the dash and the bow rather than mixing brands.
Where the Lowrance HDS PRO side imaging fish finder falls short
Setup is more involved than the Elite FS. Reviewers describe configuration as the most demanding part of getting this unit running, and first-time owners should budget time for it.
At 4.1 stars from a small pool, long-term reliability is simply not well documented yet. ActiveTarget 2 live sonar is a separate purchase on top of an already high outlay.
8. Simrad GO9: Best Side Imaging Fish Finder Outside the Big Three Brands
Simrad GO9 XSE Chartplotter and Fishfinder with 83/200 Transom Mount Transducer and C-MAP Discover Chart Card, 9 Inch Screen, Black, 000-16293-001
9-inch touchscreen MFD
C-MAP DISCOVER card
83/200 kHz HDI transducer
NMEA 2000 and Wi-Fi
Pros
- Bright 9-inch touchscreen readable in direct sun
- Intuitive interface that is easy to upgrade into from an older GO
- Included C-MAP DISCOVER card with custom depth shading and contours
- Radar and additional transducer options add capability later
- Screen mirroring to a phone or tablet
Cons
- Base 83/200 kHz bundle is CHIRP and DownScan only and needs the Active Imaging 3-in-1 transducer for side scan
- Some owners reported losing stored waypoints and tracks after a software update
- Transducer cable length can run short
Simrad is the one brand on this list that the big three roundups skip, and the GO series is a reasonable alternative for a boat that also needs radar. The screen mirrors to a phone or tablet, and NMEA 2000 support is solid.
The 9-inch panel is bright and the interface is clean enough that owners upgrading from an older GO report little relearning. The C-MAP DISCOVER card includes vector charts, custom depth shading, tides and currents and bathymetric contours.
One thing to check before buying: the base 83/200 kHz HDI transducer gives you CHIRP and DownScan, not side scan. You need the Active Imaging 3-in-1 transducer variant for this list to be the right choice for your boat.
Connectivity covers Bluetooth, Ethernet and Wi-Fi, with dashboard, panel and bracket mounting options. That flexibility makes it a decent middle unit between a bass boat and a centre console.
A few owners reported losing stored waypoints and tracks after a software update, and the transducer cable length can be too short for a console run without an extension.
Who the Simrad GO9 side imaging fish finder suits
It suits an angler who wants a hybrid marine setup, where the same head handles sonar, chartplotter and later a radar dome. The mounting options are the reason.
If you are already deep in the Simrad or Navionics ecosystem, or you fish both a bass boat and a centre console, this avoids a relearning curve.
Where the Simrad GO9 side imaging fish finder falls short
The transducer question is the big one. Get the base bundle by mistake and you have a fine fish finder with no side scan, which is precisely what this guide is about.
Community coverage is thin compared with Humminbird, Garmin and Lowrance, so troubleshooting advice is harder to find. The awkward suncover is a smaller annoyance that owners mention repeatedly.
9. Lowrance HOOK Reveal 5 SplitShot: Best Budget Side Imaging Fish Finder Entry Point
Lowrance HOOK Reveal 5 SplitShot – 5-inch Fish Finder with SplitShot Transducer, Preloaded C-MAP US Inland Mapping
5-inch SolarMAX display
SplitShot CHIRP plus DownScan
4,000 US inland lakes
1-year warranty
Pros
- Works out of the box and loads lake maps immediately
- SolarMAX 5-inch screen is crisp in direct sunlight
- SplitShot adds DownScan structure detail over basic CHIRP
- Autotuning sonar adjusts settings between trips
- Light at 14.4 ounces for tight console spaces
Cons
- Five-inch screen is genuinely small especially for older anglers
- SplitShot is CHIRP plus DownScan and gives no side imaging
- Cable routing through the boat wiring channel is tedious
- Some buyers had transducer to head-unit communication failures
Be clear about what this is. The SplitShot transducer combines wide-angle high CHIRP with DownScan Imaging, and it gives you no side imaging at all. It is the budget starting point that most anglers buy first and then outgrow.
What you do get works well. The SolarMAX screen is readable in daylight, autotuning sonar adjusts itself between trips, and maps of almost 4,000 US inland lakes load immediately with Genesis Live for custom contours.
At 14.4 ounces it mounts anywhere, including a small bass boat console with limited dash room or a jon boat where space is tight. Setup is close to plug and play for anyone who has installed a fish finder before.
The complaints are consistent: the screen is small, the cable routing is a tedious job, and a minority of units had transducer to head-unit communication failures that needed troubleshooting.
Who the Lowrance HOOK Reveal 5 side imaging entry point suits
It suits a weekend angler on a small boat who wants DownScan structure pictures and inland mapping without spending much. We would start here and add side imaging later.
If you fish a jon boat or a small bass boat, the size and weight work in your favour where a 10-inch head physically will not fit. See our portable fish finder picks for smaller craft.
Where the Lowrance HOOK Reveal 5 side imaging entry point falls short
The lack of side imaging is the decisive limitation for this topic. You cannot read a ledge to the side of the boat without it, and no amount of screen tuning changes that.
Five inches is small for anyone over fifty or anyone who wears glasses. Split panes become unreadable at that size, and older anglers regularly report straining to read it.
10. Garmin GPSMAP 943xsv: Best Side Imaging Fish Finder for Full Navigation
Garmin 010-02366-61 GPSMAP 943xsv SideVü
9-inch IPS display
SideVu and ClearVu sonar
Navionics+ mapping
Flush mount installation
Pros
- Ultra high-definition scanning sonar across SideVu and ClearVu
- Navionics+ charting preloaded and ready to run
- Improved IPS display optics for bright sunlight
- Flush mount suits a permanent console install
- Panoptix sonar support for future expansion
Cons
- Flush mount is not a simple swap for an existing transom unit
- Networking and transducer configuration suits experienced installers
- Premium cost against a small review base for long-term reliability
This is the navigation-first option. Navionics+ charts load as standard, so the unit functions as a full chartplotter rather than a fish finder that needs a phone to show you where you are.
Sonar is no slunch either. Ultra high-definition scanning sonar runs across SideVu, ClearVu and traditional CHIRP, and owners report spotting small structure at 60 to 100 feet with minimal settings work.
The IPS display optics are the quiet advantage. Flush mounting puts it level in the console, and owners switching from an older transom-mounted unit say the screen quality and layout make the boat look factory rather than assembled.
Who the Garmin GPSMAP 943xsv side imaging fish finder suits
It suits an angler whose console is already a permanent install and who wants chartplotter and side scan in one nine-inch panel. Navionics+ coverage makes it the pick for water you navigate by chart.
Panoptix support means the head can take on a forward-looking or 360 view later, which covers the question anglers ask most about adding live sonar down the road.
Where the Garmin GPSMAP 943xsv side imaging fish finder falls short
Flush mount is not a weekend swap. If your current unit hangs on a bracket you will be cutting a hole in the console and running cable behind the dash, or paying an installer.
The review pool is small, which makes long-term reliability hard to judge. Owners also point out that side scan detail on nine-inch Garmin screens is thinner than the very largest models in the range.
How to Choose Side Imaging Fish Finders for a Bass Boat
Screen size is the first decision, and the honest answer is that bigger is better only until you split the screen. A nine or ten inch panel gives you side scan plus chart plus down imaging in three legible panes, while seven inches forces a choice.
Sonar technology is the second. Garmin uses SideVu, Humminbird uses MEGA Side Imaging or CHIRP Side Imaging, Lowrance uses SideScan within Active Imaging and Simrad relies on Active Imaging hardware. These are not interchangeable, so comparing range across brands is rough; compare instead the number of feet where the picture still resolves detail.
Range per side is where the marketing runs ahead. Two hundred feet is an open-water maximum under ideal conditions. Pros we have spoken with treat 60 to 100 feet as the number that actually matters on a typical bass lake, and they build their routes around that.
Mapping is the third decision. Humminbird’s LakeMaster and AutoChart Live are regarded as the best self-made charting, Lowrance ships C-MAP DISCOVER onboard its mid and upper units, and Garmin relies on Quickdraw Contours plus Navionics. If you break down new lakes every season, spend your money here.
Networking matters if you plan more than one screen. NMEA 2000 is the common thread across all these brands, and matching your electronics brand to your existing trolling motor brand removes most of the headaches. Minn Kota integration is the most commonly praised pairing in forum discussion.
Transducer mounting is where budget installs fail. Through-hull gives a stable, clean image and is worth doing properly on a permanent rig. A transom or trolling motor mount is faster but sensitive to height and angle, and that sensitivity shows up as inconsistent side scan detail.
Power is the last piece. A single head draws modestly, but a triple-screen rig with forward-facing sonar needs heavy-gauge wiring and a dedicated lithium battery to run a full day. Plan the electrical before you plan the screens.
How to Read Side Scan on a Bass Boat Side Imaging Fish Finder
Side scan reads differently from forward-facing sonar, and the confusion is usually about what the shapes mean rather than whether the unit works.
Start with the black bar. The vertical black channel down the middle of the screen is the depth directly beneath the boat. Marking your trolling motor track along it is how you record a path across a flat.
Read outward from the bar. Water directly beside the hull is always clearest. Image degrades with distance, so the first ten feet to each side are the ones you can trust for fine detail.
Look for the shadow. Hard objects return a bright mark and cast a dark shadow behind them. A bright return with a long shadow behind it is a rock, log or brush pile. A bright return with no shadow is often a fish holding tight.
Trace the bottom line. A flat bottom returns a continuous, even line. A ledge shows as a sudden jump, and the shadow behind it marks the drop. Weed edges appear as a fuzzy, textured band.
Mark and move on. Baitfish show as small scattered marks in open water. Rather than chase them, mark the spot and use forward-facing sonar or down riggers for the final approach.
One tuning note that matters more than people expect: set the colour palette before you set the gain. A high-contrast palette separates brush from bottom better in stained water, while a muted palette reads cleaner in a clear reservoir.
Shallow Water Limits of Side Imaging Fish Finders for Bass Boats
Side scan performs worst in water under ten feet, and this is the most common unresolved complaint in bass fishing forums. There is a physical reason: the beam needs water to travel through, so a beam that reaches 100 feet in a reservoir may only show 20 or 30 feet across a flooded creek.
The picture also gets busier. Your own hull, docks, overhanging branches and tree shadows all come back as returns, so the screen fills with structure that is not fish-holding. Filtering helps, but there is no setting that invents range.
What works in practice is to treat shallow side scan as a close-range tool. Use it for brush piles and creek structure within a few boat lengths, where image quality is highest, and switch to down imaging for anything directly under the hull.
Product choice matters here too. Heads with higher-frequency side scan channels hold detail better in the shallows, and the MEGA Side Imaging models hold up better than the entry-level CHIRP side imaging units in our testing.
Humminbird vs Garmin vs Lowrance Side Imaging Fish Finders for Bass Boats
Forum consensus, and our own testing, lands in the same place: Humminbird for mapping and side scan detail, Garmin for navigation and a clean interface, Lowrance for value and for being fishable on default settings.
Garmin wins on menus. Nobody fumbles a Garmin unit, and the ActiveCaptain app handles notifications and waypoint transfer without ceremony. Side scan detail is the trade-off, and it is thinner below ten inches than the equivalent Humminbird.
Humminbird wins on the picture and the mapping. LakeMaster and AutoChart Live remain the tools of choice for building your own lake charts, and MEGA Side Imaging gives the longest usable reach. Forum discussion does raise a fair question about hardware failure rates, so buying through an authorised dealer is the sensible move.
Lowrance wins on value and on simplicity. Active Imaging 3-in-1 puts side scan, down imaging and CHIRP behind one transducer, and anglers report running them on factory settings competitively. Side scan detail has improved a great deal and is no longer the gap it once was.
Simrad is the outsider worth knowing. The GO series handles NMEA 2000 and radar well, though you must choose the Active Imaging 3-in-1 transducer package to get side scan.
Frequently Asked Questions
Which fish finder has the best side view?
For bass boats, the Humminbird XPLORE 10 leads on range per side with MEGA Side Imaging+ at 200 feet, while the Garmin STRIKER 7SV is the strongest all-round choice because it pairs SideVu scanning sonar with Quickdraw Contours mapping at a much lower outlay. The Humminbird picture resolves more detail at range; the Garmin is easier to run.
What is the best fish finder for a bass boat?
It depends on your console and trolling motor. A single-screen boat usually does well with a 7 to 9 inch unit such as the Garmin STRIKER 7SV or the Humminbird HELIX 7 CHIRP SI G4. A console that will host three screens wants a 10 inch networked head like the Lowrance Elite FS 10 or the Humminbird XPLORE 10.
Is Humminbird side imaging better than Garmin?
Generally yes on image detail and on mapping tools, especially at 9 inches and above. Humminbird’s MEGA Side Imaging and AutoChart Live are widely preferred by bass anglers. Garmin is easier to operate, has better navigation and stronger live sonar options, but its side scan detail on smaller screens is thinner. Below ten inches the gap narrows.
What is the best budget side imaging fish finder?
The Garmin STRIKER 7SV is our budget side imaging pick because it ships with a SideVu capable transducer, transom and trolling motor mounts and Quickdraw Contours mapping. For a strict entry point below that, the Lowrance HOOK Reveal 5 SplitShot is cheaper but gives no side imaging, only CHIRP and DownScan.
Is side imaging worth it for bass fishing?
Yes. Side scan lets you cover 100 to 200 feet of water per pass and read structure without running over it, which lets you mark and revisit spots instead of fishing them once. Most anglers side scan an area, mark the structure, then switch to forward-facing sonar or down riggers for the final approach.
What are the disadvantages of side scan sonar?
Side scan is weaker in shallow water under ten feet, where the beam has little room to travel. Docks, trees and your own hull create shadowing and false returns. Range falls off quickly outside the advertised maximum, the picture tells you little about what the target actually is, and adding live sonar to a full rig costs power and wiring.
What do fish look like on side imaging?
Fish show as small bright marks or short arcs in open water, often with no shadow behind them, while rocks, logs and brush piles return a bright mark with a dark shadow behind it. A baitfish ball shows as a loose cluster of marks near the bottom or off a drop-off, and the black depth bar down the centre of the screen gives you the depth beneath the boat.
How far to each side can side scan realistically read?
Treat 60 to 100 feet per side as the number that matters in practice, not the advertised maximum of 200 feet. Professional bass anglers build their trolling motor tracks around that range. Maximum figures are measured in open water under ideal conditions, and on a normal lake with structure and stained water the readable range is shorter.
Final Verdict on the Best Side Imaging Fish Finders for Bass Boats
The Garmin STRIKER 7SV is our pick for the best side imaging fish finders for bass boats because it does the one thing this category exists for, clearly and simply, and it ships with everything needed to mount it on a trolling motor. If you need more screen and a chartplotter in the same head, the Lowrance Elite FS 10 is the step up. If you fish open water and want the longest reach, the Humminbird XPLORE 10 wins on MEGA Side Imaging+.
Whichever you choose, install the transducer properly before you judge the picture. A through-hull mount on a permanent rig, or correct height and angle on a transom mount, makes more difference to your side scan than any setting on the unit.
