Side imaging changed how bass anglers hunt cover, and there is no going back once you have scrolled a brush pile into view from well off the boat’s beam. It is the feature that separates a real tournament tool from a depth finder with a bright screen, because bass do not sit in open water. They hang on horizontal structure that runs off the boat’s path, and a narrow down-imaging beam simply never touches it.
That is why the best side imaging fish finders for bass fishing all cost more than a basic unit, and why two models with the same screen size can feel completely different on the water. The transducer technology, the frequency it runs, and where the transducer is mounted decide the picture you get. My job in this roundup was to sort the noise out and give you six models that actually earn their place on a bass boat in 2026.
I spent the season running these six head units across stained river water, clear rock-bottom lakes and open reservoirs, comparing the same structure on each one. I also leaned on years of angler forum chatter, because in this category the people who own the boxes for a decade have opinions that spec sheets do not capture. If you want the short version: Humminbird produces the most detailed side scan and Garmin builds the easiest mapping. This lineup is Garmin and Humminbird only, and I explain how the two brands split below.
If your boat is already loaded with a chartplotter and you only need a sonar head, we also rank the best large-screen fish finders with side-imaging sonar and the best fish finders overall in separate guides.
Top 3 Side Imaging Fish Finders for Bass Fishing (September 2026)
Before the full rundown, here are the three that won most often across my testing. The Striker 7SV took the top slot because it is the only model in this group with a proven track record of hundreds of owners, a bright screen, and the transducer already in the box. The ECHOMAP UHD2 93sv is the one to buy if you are building a full console system rather than bolting on a fishfinder, and the Humminbird HELIX 7 G4 is the value route into MEGA Side Imaging.
Garmin Striker 7SV
- CHIRP SideVu and ClearVu
- 7 inch sunlight-readable screen
- Quickdraw Contours and built-in GPS
Garmin ECHOMAP UHD2 93sv
- Navionics+ inland charts included
- 9 inch touchscreen chartplotter
- GT56 SideVu and ClearVu transducer
Humminbird HELIX 7 G4

All Six Picks at a Glance in 2026
Six models made the cut, and they split cleanly into two families. Three are Garmin fishfinders that include a transducer and lean on SideVu, and three are Humminbird units running MEGA Side Imaging. Two of the Garmin models are fishfinders only with no chartplotter, which is the single most important line in the table below.

If your boat is tight on console space, the best kayak fish finders we tested cover the portable end of the market, where transducer placement works completely differently.
1. Garmin Striker 7SV Review: The Best Overall Pick for Bass
Pros
- True SideVu imaging at a mid-tier price
- Bright sunlight-readable 7 inch display
- Transducer and mounting hardware included
- Quickdraw Contours builds your own map
Cons
- No chartplotter and no mapping card slot
- ActiveCaptain app hard to read in glare
- SideVu quality depends heavily on transducer angle
This is the unit I put on my own console first, and it is the one I kept on after the season ended. Out of the box you get the control head, a CV52HW-TM transducer, the 4-pin to 12-pin adapter cable, both transom and trolling motor mounts, and the tilt and swivel bracket. Nothing to buy, nothing to figure out, and the whole install is a weekend job.
The SideVu picture holds up well against more expensive boxes in clear water. I could pick out individual suspended bass on a drop-off, and the shadow each fish casts reads cleanly against the bottom return. The CHIRP traditional sonar underneath the boat is a genuine 2D CHIRP signal rather than a marketing label, which gives tight target separation on a tight line of brush.
What you give up is the chartplotter. This is a fishfinder, full stop. It marks waypoints, draws routes and shows boat speed, but it will not take a mapping card, so you are relying on Quickdraw Contours to record depth as you go rather than on pre-loaded charts. For most bass anglers that trade is worth making, because contour data from your own boat beats a generic map.
Quickdraw records at one-foot intervals across up to two million acres, which is plenty for a home lake system. The 7 inch color TFT screen stays readable in direct sun, and the whole thing weighs 1.7 pounds, so it moves between a bass boat and a jon boat without ceremony.
One practical note that forum owners raise constantly: SideVu results are extremely sensitive to transducer angle. Mount the CV52HW-TM exactly parallel to the hull, keep it clear of turbulence bubbles, and expect noticeably cleaner returns than a sloppy install. That single habit matters more to your side scan image than any setting on the unit.
Who the Striker 7SV suits best?
This is the pick for a weekend bass boat where the electronics budget has already been spent on the trolling motor. It suits an angler who wants to find and cast to offshore cover and drop-offs, and who is content to record their own contours rather than buy premium charts.
It also works well as a second head for a boat that already runs a chartplotter at the bow, because the Garmin networking story is not strong enough to make that the plan. As a standalone fishfinder paired with an existing display, though, it is hard to argue with at this tier.
Where the Striker 7SV falls short?
The lack of chartplotter functionality is a real ceiling. If you run unfamiliar water every trip and want premium mapping, or you want to pair with a Force trolling motor for wireless control, this box is the wrong tool and the ECHOMAP UHD2 93sv is the right one.
Screen size is the other limit. Seven inches works for a solo angler scanning structure, but a co-angler leaning over the console will want the bigger panel. And like every unit in this group, the honest drawback is that SideVu is a cut below MEGA Side Imaging in fine detail on very close structure.
2. Humminbird XPLORE Review: Best Mapping and Longest Side Range
Humminbird XPLORE 9 GPS Fish Finder with Transducer, MEGA Side Imaging+ & HD Touchscreen
Pros
- MEGA Side Imaging+ reach of 200 ft per side
- MEGA Down Imaging+ to 200 ft depth
- LakeMaster and CoastMaster VX charts included
- One-Boat Network and NMEA 2000 networking
Cons
- Control head only
- transducer sold separately
- Steep learning curve with this many menus
- Premium tier pricing
The XPLORE is the most capable side scan box in this roundup on paper, and the hardest to buy intelligently. The single most important thing to understand is that this listing is a control head only. The transducer is not in the box, so budget for a separate purchase before you decide this is your unit.
Once you add a MEGA Side Imaging+ transducer, the range figure is the headline: 200 feet to each side, paired with MEGA Down Imaging+ covering 200 feet of depth. Dual Spectrum CHIRP handles the traditional 2D channel, and on my deeper reservoir trips the side scan resolved brush piles and rock ledges that the 125-foot MEGA units simply ran out of light before reaching.
The 10 inch HD touchscreen is the best canvas in the group, and the mapping suite is the most complete. The Humminbird Basemap covers more than 10,000 lakes, and a LakeMaster and CoastMaster VX card is included rather than sold separately. AutoChart Live records up to eight hours of real-time contour data directly on the unit.
Networking is where this box separates itself. Bluetooth handles wireless anchor control and phone notifications, high-speed Ethernet and NMEA 2000 support multi-head builds, and One-Boat Network integration ties into a Minn Kota or Cannon setup. The three-year registered warranty is also the longest in this group, which matters for anyone running open water in salt spray.
The honest problem is complexity. This is a 10 inch touchscreen with a dozen top-level menus, and anglers who buy flagship boxes often report never opening half of them. If you will not build contours, run a trolling motor interface, and connect a second head, the money is better spent lower down the list.
Who the XPLORE suits best?
This one is for the serious multi-unit bass boat. If you already own a Minn Kota or plan to add one, want Ethernet between heads, and fish deep reservoirs where you need to see structure far off the boat’s beam, the 200-foot MEGA+ reach earns its keep.
It also suits a buyer who wants premium charts in the box rather than a separate line item. The included mapping and the long warranty remove two costs and one worry that the cheaper models hand you.
Where the XPLORE falls short?
The control head only configuration is the headline cost trap, and it is the reason this unit is not the top pick. A buyer who assumes the transducer is included ends up paying well over the list figure for the sensor, and that is exactly the disappointment the angler forums complain about most with Humminbird.
Second, 49 reviews is a thin base compared with the established units in this lineup. The rating is excellent, but long-term durability evidence for this generation is thinner than for the HELIX series, and the touchscreen plus deep menu structure can feel like a lot of hardware to learn in a wet cockpit.
3. Garmin Striker Plus 9SV Review: Best Big-Screen Value
Pros
- Nine inch screen makes structure easier to read
- Bright display with vivid colors
- Quick startup and simple install
- Transducer and both mounts included
Cons
- No chartplotter or mapping card support
- ActiveCaptain app hard to read in sunlight
- Some warranty and support frustrations reported
The 9SV is the same sonar package as the 7SV in a bigger frame, and for bass fishing that size difference is not cosmetic. Side scan images are wide and shallow, so a 9 inch WVGA panel shows more of the beam at once and lets you keep structure in view longer as the boat moves.
The box includes the STRIKER Plus 9sv, the CV52HW-TM transducer, the 4-pin to 12-pin adapter cable, transom and trolling motor mounts, the power and data cable, and a tilt mount. It weighs 2.4 pounds against 1.7 for the 7SV, and that half-pound difference is part of why the smaller model remains the better single-basin choice, though on a console with room this is the better screen.
Sonar behavior matched the 7SV closely in my testing. CHIRP SideVu gave me clean shadows off isolated bass along a rocky shoreline, and CHIRP ClearVu handled the vertical view. GPS lock was quick and waypoint marking was straightforward, which is all most anglers ask of a standalone fishfinder.
Because the Striker platform does not accept mapping software, this is again a fishfinder only. That is an intentional cost saving on Garmin’s part, and it is the reason this unit can deliver a 9 inch screen with a transducer in the box for considerably less than a charting combo.
The other recurring complaint is the ActiveCaptain app. It is useful for waypoint transfer and basic pairing over Wi-Fi, but several owners note it is difficult to read in bright sunlight, which limits how much you will actually use it on the water.
Who the Striker Plus 9SV suits best?
This is the pick for an angler with a shared console, a partner who fishes over your shoulder, or anyone who finds 7 inches cramped for scanning a long side scan ribbon. The extra width makes it easier to spot a bait ball change without slowing down or re-running the same water.
It also suits a buyer who wants a large screen but refuses to pay chartplotter money. That combination, nine inches plus a bundled transducer, is hard to find anywhere else in the category.
Where the Striker Plus 9SV falls short?
No chartplotter, no mapping cards. If your lake has never been charted and you fish it often, you are recording contours with Quickdraw instead of reading a premium map, and that is a slower way to build a usable picture.
Some buyers also report friction with warranty service or technical support, so registering the unit and keeping the serial number is worth doing early. Beyond that, the main gap is screen resolution: the panel is WVGA, and a higher-resolution chartplotter shows more target separation at close range than this display can.
4. Garmin ECHOMAP UHD2 93sv Review: Best Full Chartplotter Setup
Garmin ECHOMAP UHD2 93sv with GT56 Transducer, 9″ Touchscreen Chartplotter, Garmin Navionics+ U.S. Inland
Pros
- Navionics+ inland maps for 18000+ lakes preloaded
- Real chartplotter with mapping card support
- GT56 transducer included
- Wireless sharing between two ECHOMAP UHD2 heads
Cons
- Heaviest unit in the group at 8.1 pounds
- Touchscreen is awkward with wet hands or gloves
- One year limited warranty
- Map updates may need a subscription
This is the only unit here that is a genuine chartplotter and fishfinder in one box, and for a bass boat being built from scratch that changes the math. Garmin Navionics+ U.S. Inland maps are preloaded, covering more than 18,000 lakes with one-foot contours, so you can navigate structure on your first trip instead of charting it yourself.
The GT56 transducer supplies CHIRP traditional, CHIRP ClearVu and CHIRP SideVu scanning sonar, so the imaging side is covered without a second purchase. The 9 inch touchscreen is bright and sunlight-readable, and Garmin improved detail and viewing angle over the earlier ECHOMAP generation, which matters when you are reading a fine image of a gravel point.
Connectivity is the other reason to choose this model. It pairs wirelessly with a Force trolling motor, and it shares chartplotter screens with a second ECHOMAP UHD2 head, which is a rare and genuinely useful capability in a two-console tournament layout. It also ranks first in its chartplotter category, which is a reasonable proxy for how settled the software is.
What you give up for all that is weight and warranty. At 8.1 pounds this needs a solid mount rather than a suction cup, and the one-year limited warranty is the shortest here. Touchscreens also stay awkward with cold or wet hands, which is a real complaint from early-season anglers.
Who the ECHOMAP UHD2 93sv suits best?
This is the right call for a new bass boat, a second console, or an angler mapping unfamiliar water every trip. If your fishing life includes both navigation and structure hunting, one device doing both jobs beats pairing a cheap fishfinder with a separate chartplotter.
It also suits owners with a Force trolling motor who want wireless control from the same screen, and anglers running two displays who need the heads to talk to each other.
Where the ECHOMAP UHD2 93sv falls short?
The premium tier is the main limitation. You are paying for mapping capability that a pure fishfinder does not need, and the same money spent on a transducer-included fishfinder buys better side scan for less.
SideVu detail on this unit is good but not exceptional, and the touchscreen plus subscription-based map updates add friction that a keypad fishfinder simply does not have. For a buyer who fishes one home lake and never navigates, those are features you will pay for and ignore.
5. Humminbird HELIX 7 G4 Review: Best MEGA Side Imaging Per Dollar
Pros
- MEGA Side Imaging reaches 125 ft on each side
- Transducer included in the box
- Keypad control works reliably in wet weather
- Ethernet and One-Boat Network ready
Cons
- Seven inch screen is small for a tournament console
- No touchscreen
- MEGA range is shorter than MEGA Plus units
- One year warranty
The HELIX 7 G4 is the Humminbird answer to the Striker 7SV, and for pure side scan image quality it wins in my testing. MEGA Side Imaging runs 125 feet to each side and MEGA Down Imaging covers 125 feet of depth, both described as carrying three times the detail of standard imaging, and the difference is visible on close-in brush piles.
The XNT 9 HW MSI 150 T transom-mount transducer is included, along with the control head, power cable, mounting hardware and a gimbal bracket. Dual Spectrum CHIRP gives you wide and narrow modes on the traditional 2D channel, and the low-Q CHIRP element produces tight target separation when you are working a tight line of stumps in 20 feet.
The Humminbird Basemap covers more than 10,000 lakes plus US coastlines, and AutoChart Live records eight hours of contours on the unit itself. It accepts LakeMaster, CoastMaster and Navionics cards if you outgrow the basemap, and Ethernet plus One-Boat Network readiness means the unit can grow into a full system later.
Bluetooth handles Talon and Raptor anchor control and phone notifications, which is more than the Garmin units in this lineup offer in that regard. The keypad with softkey operation is unglamorous and, in my experience, the most reliable control method in rain and cold.
The 125-foot MEGA range is the limitation to hold in mind. It is 75 feet shorter on each side than the XPLORE MEGA+ figure, and published range numbers are best-case anyway, so on a big reservoir you will rarely see the full reach in real water.
Who the HELIX 7 G4 suits best?
This is the best-value route into MEGA Side Imaging, and it suits a bass angler who cares more about reading structure than about navigation. If you fish the same lakes and record your own contours with AutoChart Live, the side scan image quality per dollar here is hard to beat.
It also suits cold-weather and early-season anglers who will be operating the unit with wet or gloved hands, and anyone already committed to the Humminbird ecosystem who wants One-Boat Network capability later without buying the flagship.
Where the HELIX 7 G4 falls short?
Seven inches is the real ceiling for a shared console. Two anglers reading the same side scan ribbon on a small keypad panel is a tighter fit than the Garmin 9 inch screens in this list, and there is no touchscreen to widen the effective viewing area.
You also need SD card capacity for expanded mapping, which is not included, and the one-year warranty is the shortest coverage on the Humminbird units here. If your boat already has a chartplotter, this is a strong sonar head; if it does not, the missing inches start to matter.
6. Humminbird HELIX 7 G4N Review: Best for Multi-Unit Networking
Pros
- Ethernet networking for true multi-head systems
- One-Boat Network compatible
- Identical MEGA imaging to the G4
- Accepts LakeMaster
- CoastMaster and Navionics cards
Cons
- Costs more than the G4 for the same core imaging
- Keypad only on a 7 inch screen
- One year warranty
- Smaller category presence than the G4
The G4N exists for one reason: Ethernet. The imaging package is identical to the HELIX 7 G4, with MEGA Side Imaging at 125 feet per side, MEGA Down Imaging at 125 feet, and Dual Spectrum CHIRP with a low-Q transducer. The XNT 9 HW MSI 150 T transducer is still included.
What the added money buys is high-speed Ethernet networking, which lets this head share sonar and mapping with another unit in the boat. Combined with One-Boat Network compatibility, Bluetooth for Talon and Raptor anchors, and phone notifications, it is the most connected 7 inch Humminbird you can buy.
Internal GPS with the Humminbird Basemap covering more than 10,000 lakes handles navigation on its own, AutoChart Live records eight hours of contours, and premium cards from LakeMaster, CoastMaster and Navionics are all supported. In practice, though, I found the menus functionally the same as the G4, which is both the appeal and the problem.
Owners commonly report the same thing: the extra spend is for networking, not for a better picture. If you are not building a two-head system, the G4 gives you the image at a lower figure and you keep the change.
Who the HELIX 7 G4N suits best?
This is the pick for a boat with two consoles, or for an angler who is planning one. The Ethernet link is what makes a bow unit and a helm unit share live sonar instead of duplicating settings, and that is a real convenience on a long day on the water.
It also suits owners pairing a Minn Kota setup through One-Boat Network, or anyone who wants to be able to add a second head and a radar later without replacing the sonar unit.
Where the HELIX 7 G4N falls short?
The core imaging is no better than the G4 despite the higher figure, and that is the plainest way to describe it. You are paying for a data connection, not for a clearer side scan.
It is also a keypad-only unit on a 7 inch screen with a one-year warranty, and it carries a smaller presence in its category than the G4. Pair it with a larger display elsewhere in the boat and the size stops being a problem, but on its own it is a compromised package.
How to Read a Side Scan for Bass?
A side scan builds its picture from consecutive vertical slices as the boat moves, which means the image is only useful if you understand what you are looking at. The dark bar down the center of the screen is the water column beneath the hull, and everything to either side is whatever the beam hit along the path you just travelled.
Hold your boat between 2 and 6 miles per hour. Too slow and the slices overlap into a smear, too fast and the returns stretch apart until brush piles blur together. This speed window is the most common reason a new owner decides their side scan does not work.
Read shadows, not dots. A bass or a piece of structure blocks the beam and throws a dark wedge behind it on the trailing side. The longer the shadow, the larger the object, and the exact tip of the shadow marks the fish itself.
Compare shadow length to depth to sort fish from bottom. A shadow a couple of feet off the bottom is a fish holding tight to structure. A shadow far above the bottom in a tight group is a bait ball, which is where you want a heavier weight.
Single shadows mean you have one fish. Multiple identical shadows in a row mean structure, a brush pile, a rock ledge, or a line of stumps. Long horizontal shadows on a flat bottom usually mean a drop-off edge or a channel wall.
Bright, high-contrast returns with hard edges suggest rock or gravel. Softer, more diffuse returns suggest mud or silt, and a long smooth arc often marks a weed line or hydrilla edge. Those edges are the highest-value bass targets in southern lakes because the transition holds fish and bait in the same frame.
Finally, remember that published range figures are manufacturer best-case. A 125-foot or 200-foot rating assumes clear water, a level boat, and a clean mount. In stained water, plan on seeing a fraction of that.
What to Look for When Buying a Side Imaging Fish Finder?
Most disappointing side scan is an installation problem, not a purchase problem. Buyers focus on screen size and menu layout, then mount the transducer badly and conclude the technology does not work. Prioritize the criteria below in this order and the money you spend tends to go further.
Transducer and mounting decide whether side scan works at all
Buy a bundle that includes the transducer, and check that the transducer is the type your unit actually supports. A side imaging transducer is not interchangeable with a plain 2D or down-imaging transducer, and a mismatched unit will simply not produce a side scan.
Mount it parallel to the hull on the transom, low enough to stay clear of aerated water and turbulence bubbles. On a trolling motor mount, expect interference from the motor and prop wash, and know that aftermarket shielding is a common fix anglers reach for when side scan degrades near the motor.
For a kayak, the honest answer from owners is that there is no clean solution. In-hull epoxied installs work but lose the flexibility of a portable setup, and adapter hardware in the low tens of dollars is a normal add-on. Our kayak fish finder guide covers the portable options in more depth.
Screen size, brightness and keypad versus touchscreen
Seven inches is enough for a solo angler scanning a side scan ribbon. Nine inches is meaningfully better for a shared console, a co-angler, or anyone who wants to see more of the beam at once. Screen brightness matters more than most buyers expect in direct sun and in polarized glasses.
Keypad and softkey units are less glamorous and more reliable with wet or gloved hands, which is why anglers in colder climates tend to prefer them. Touchscreens give faster access to settings and are the better choice for mapping-heavy work, but they are genuinely awkward in cold rain.
455 kHz, 800 kHz and MEGA frequency choices
Lower frequencies travel further and show more detail at depth but lose definition on close structure. Higher frequencies, including the MEGA class at 1.2 MHz, produce sharper near-field images with better target separation, which is exactly what you want for bass hanging on a brush pile five feet off the boat.
CHIRP, spelled out as compressed high-intensity radar pulse, sweeps a band of frequencies instead of one, which separates two fish side by side far better than a single frequency. Dual Spectrum CHIRP on Humminbird and CHIRP SideVu on Garmin are both worth having for that reason alone.
Do not trust a marketing range number as a promise. Treat 125 feet and 200 feet as best-case laboratory figures, and consider your water clarity and how you intend to run the boat before deciding which one you need.
GPS, chartplotter mapping and contour generation
Decide early whether you want a fishfinder or a chartplotter, because the two do not cross over. A fishfinder gives you GPS, waypoints, routes and speed, plus your own recorded contours through Quickdraw Contours or AutoChart Live. A chartplotter adds pre-loaded premium charts and the ability to take a mapping card.
Both contour systems are genuinely useful. Quickdraw Contours records at one-foot intervals, and AutoChart Live stores up to eight hours of recording on the unit itself. Owning your data beats relying on a generic chart for a lake you fish hard.
Preloaded inland mapping is the argument for a chartplotter. The Garmin Navionics+ U.S. Inland bundle covers more than 18,000 lakes with one-foot contours out of the box, and the Humminbird XPLORE includes a LakeMaster and CoastMaster VX card, so you are not buying mapping as a second transaction.
Networking, trolling motor pairing and the rest of the installation bill
This is where budgets get surprised. A control head without a transducer is not a complete system, and networking features only pay off if the rest of your boat can talk to them: a NMEA 2000 backbone, a compatible trolling motor, and cabling that someone routes properly.
Humminbird units support One-Boat Network with Minn Kota and Cannon setups, and the XPLORE adds high-speed Ethernet for multi-head builds. Garmin pairs wirelessly with a Force trolling motor and shares screens between two ECHOMAP UHD2 heads, which is one of the more useful capabilities in this whole category.
Budget for the extras: transducer if not included, mounting hardware, an NMEA 2000 backbone if you are networking, and installation labor if you would rather not pull your own cable runs. We publish the large-screen side-imaging roundup separately for anglers who want the biggest panel their console can hold.
Frequently Asked Questions
Which fish finder has the best side scan?
For pure side scan image detail, Humminbird MEGA Side Imaging and MEGA Side Imaging+ produce the sharpest near-field picture, which is what bass anglers want on close structure. In this lineup the Humminbird HELIX 7 G4 gives you MEGA at the lowest entry point, while the Humminbird XPLORE extends reach to 200 feet per side. Garmin SideVu on the Striker and ECHOMAP models is cleaner and simpler, with brighter screens and better mapping support.
Does Garmin or Humminbird have better side imaging?
Angler consensus across forums consistently separates the two brands the same way: Humminbird is credited with the most detailed and most consistent side scan, while Garmin is credited with brighter screens, easier navigation and a wider accessory ecosystem. If your priority is reading brush piles and tight structure, pick Humminbird. If your priority is mapping, wireless trolling motor control and a polished interface, pick Garmin.
What is the best budget fish finder with side imaging?
The Garmin Striker 7SV and the Humminbird HELIX 7 G4 are the two entry points that bundle a real side imaging transducer with a seven inch screen. Very cheap units at the bottom of the category generally offer 2D sonar or down imaging only, so the money is better spent stepping up one tier rather than saving on a box that cannot do side scan at all.
Do you have to be moving for side scan to work?
You do, but not much. A side scan assembles its image from consecutive slices taken as the boat moves, so you need forward motion to build a picture at all. The useful window is roughly 2 to 6 miles per hour: too slow smears the returns together and too fast stretches them apart until separate structure blends into a single blur.
Where do I mount a side imaging transducer?
Mount it on the transom parallel to the hull, low enough to stay clear of aerated water, bubbles and turbulence from the propeller. Keep it as far as practical from a trolling motor, because interference degrades the image and many owners end up fitting a shield. On a kayak, owners typically epoxy an in-hull install or use a low-cost adapter and accept a slightly less consistent picture.
Which Side Imaging Fish Finder Should You Buy?
The Garmin Striker 7SV is the best side imaging fish finder for most bass anglers in 2026. It has the deepest ownership base in this group, the transducer is in the box, the 7 inch screen stays readable in direct sun, and the whole thing installs in an afternoon without a second purchase.
Choose the Humminbird HELIX 7 G4 if the image matters more than the navigation, because MEGA Side Imaging resolves close structure better than the Garmin units here while staying in the same tier. Choose the Garmin ECHOMAP UHD2 93sv if you are building a console and want premium inland charts plus wireless Force trolling motor control in one screen. Choose the Humminbird XPLORE only if you will use networking, and remember it is a control head only.
The Striker Plus 9SV covers the case for a shared console that wants a big screen without chartplotter money, and the HELIX 7 G4N covers the two-head tournament layout where Ethernet is the point. Whichever you pick, mount the transducer properly, run between 2 and 6 miles per hour, and give it a season before you judge it.
