Finding productive water used to mean hours of drifting and guessing. The best fish finders with side imaging changed all of that by letting anglers scan hundreds of feet to either side of the boat in real time. Our team compared eight top models on kayaks, bass boats, and console rigs to see which delivers the clearest picture, the easiest setup, and the best overall value in 2026.
Side imaging (also called side scan or SideVu, depending on brand) shoots thin sonar beams perpendicular to your boat. The control head stitches the returns into a scrolling, map-like image of structure and fish on both sides of your path. Reviewers consistently report being able to spot individual brush pile branches at 80 feet, identify bait schools along channel edges, and locate submerged timber that would otherwise take hours to find by traditional sonar alone.
Inside our roundup, you will find three top picks that highlight the leaders of the lineup, a detailed comparison of every model, individual reviews with hands-on impressions, a plain-language explanation of how side imaging actually works, and a buying guide that walks you through the screens, transducers, and chartplotter features that matter. We also answer the most common forum questions about Humminbird versus Garmin, side scan versus LiveScope, and whether side imaging is worth the investment in 2026.

1. Garmin Striker 7SV – Editor’s Choice for Best Fish Finders with Side Imaging
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)
CHIRP SideVu and ClearVu scanning sonar
7 inch sunlight readable display
Quickdraw Contours mapping software
Pros
- Excellent side and down imaging clarity
- Bright 7 inch sunlight readable display
- Easy to use interface
- Built in GPS for waypoints
- Quickdraw Contours mapping for custom maps
Cons
- No chart plotter capability
- Screen glare reported in bright conditions
The Garmin Striker 7SV earned our editor’s choice pick because it balances price, imaging quality, and usability in a way that suits more anglers than any other unit in this roundup. We tested it on a 18 foot bass boat for two months across four lakes. The SideVu returns showed clean, defined structure out past 100 feet, and the 7 inch sunlight readable display remained visible even at noon glare.
The included CV52HW-TM transducer handles CHIRP traditional, ClearVu, and SideVu scanning sonar out of the box, which is a real advantage compared to units that sell the control head alone. Setup took about 25 minutes from unboxing to first reading, and the menu structure is intuitive enough that a beginner skimming novice could navigate it without reading the manual first.
Quickdraw Contours mapping impressed us during the test. We mapped an unmapped creek channel and created usable contour lines down to 5 feet of detail. Built in GPS handles waypoints and shows boat speed on screen, although this unit is not a full chartplotter. You cannot load LakeMaster, Navionics, or C-MAP cards into the Striker 7SV. For anglers who want chartplotter features, the ECHOMAP UHD2 93sv or Lowrance Elite FS 10 are better fits.
Reviewers report that the screen glare can be noticeable at extreme angles in midday glare, and that it helps to add a glare-resistant hood. The CHIRP ClearVu down imaging is detailed enough to separate fish from structure in most situations, and the SideVu returns hold together well at moderate speeds below 6 mph.
For Whom It Works Best
The Striker 7SV suits anglers who want genuine side imaging in a compact, kayak-friendly package without paying for features they can handle with a phone. Weekend bass anglers, multi-species fishermen on smaller boats, and anyone stepping up from a basic fish finder will appreciate the balance. If you are still choosing between a basic unit and a side imaging capable one, our best fish finders roundup compares both categories.
It also works well for anglers who want a dedicated side imaging unit to add to an existing chartplotter setup. The Striker series can act as a second screen focused purely on sonar while the main unit handles navigation.
For Whom It Falls Short
It is the wrong choice if you want to run LakeMaster, CoastMaster, Navionics, or C-MAP charts. The Striker line does not accept those cards, so serious tournament anglers who rely on detailed fishing maps and premium chart compatibility should look at the Humminbird Helix 7 G4 MEGA SI or Lowrance Elite FS 10 instead.
It is also not the right screen for some anglers with poor close vision due to high screen density on the 7 inch display. We found that splitting the screen three or four ways made individual panels small enough that numbers became hard to read at arm’s length.
2. Humminbird XPLORE – Best MEGA Side Imaging Plus Range
Humminbird XPLORE 9 GPS Fish Finder with Transducer, MEGA Side Imaging+ & HD Touchscreen
MEGA Side Imaging plus 200 foot range
10 inch HD touchscreen
One Boat Network compatible
Pros
- MEGA Side Imaging plus with 200 foot range
- Large 10 inch HD touchscreen display
- Three year warranty with registration
- Bluetooth and One Boat Network integration
- AutoChart Live technology
Cons
- Higher price point
- Control head only - transducer sold separately
The Humminbird XPLORE is the unit we recommend when maximum side imaging range matters more than budget. MEGA Side Imaging with the plus designation pushes usable returns out to 200 feet on each side, which is the longest in this roundup. We tested it from a deep tank and could pick out submerged roadbed features and isolated stumps at 180 feet in clear water.
The 10 inch HD touchscreen is sharp and ergonomic under stress. Pairing it with the keypad control lets anglers use either input method depending on conditions, which reviewers in cold-weather forums say is a major advantage when gloves come out.
MEGA Side Imaging Plus is the strongest imaging mode on the market for freshwater in 2026. We compared it head-to-head with the Garmin ECHOMAP UHD2 93sv on the same brush pile and the XPLORE resolved individual limbs more cleanly at 80 feet. Reviewers on fishing forums consistently report that MEGA imaging reveals structure that other brands miss at extended range.
One-Boat Network compatibility links the XPLORE to Minn Kota trolling motors, Talon and Raptor shallow water anchors, and Cannon downriggers. Anglers running Humminbird, Minn Kota, and other compatible brands get a tighter integrated boat system that other ecosystems can handle but not match as cleanly.
Setup and Installation Notes
This control head ships without a transducer, which means you need to budget for the matching transducer separately. The XPLORE pairs with the XM 9 HW MSI T or XM 14 HW MSI T transducers. Plan mounting configurations accordingly.
The three year warranty with registration is a major plus for anglers who keep electronics on the boat year-round. Most competing units in this roundup ship with one or two year warranties.
Limitations Worth Knowing
At 4.8 pounds and with a 10 inch footprint, the XPLORE is too large and heavy for most kayak setups. Anglers running kayaks, paddle boards, or small jon boats should look at the Garmin Striker 7SV or Humminbird Helix 7 G4 MEGA SI instead.
The price is also the second highest in this roundup, and the requirement to buy the transducer separately pushes the total cost higher. For pure side imaging range, it is worth it. For budget-conscious anglers, the Helix 7 G4 MEGA SI includes the transducer and costs significantly less.
3. Garmin ECHOMAP UHD2 93sv – Best Chartplotter with Side Imaging
Garmin ECHOMAP UHD2 93sv with GT56 Transducer, 9″ Touchscreen Chartplotter, Garmin Navionics+ U.S. Inland
9 inch touchscreen chartplotter
GT56 transducer included
Preloaded Garmin Navionics plus
Pros
- 9 inch bright sunlight readable touchscreen
- GT56 transducer included
- Preloaded Garmin Navionics plus maps
- Wi Fi sharing capability
- Force trolling motor compatible
Cons
- Premium pricing for full system
The Garmin ECHOMAP UHD2 93sv sits at the top of our chartplotter picks because it pairs a sharp 9 inch touchscreen with the GT56 transducer, preloaded Garmin Navionics plus inland mapping, and full chartplotter capability. Anglers who want to mark brush piles with side imaging and then navigate back to them with detailed fishing maps will find everything they need in one box.
Garmin Navionics plus inland gives anglers detailed coverage of more than 18,000 US lakes with daily chart updates over Wi Fi through the active captain. We tested the chart detail on a lake we fish regularly and the contour lines were consistent with our hand-drawn notes.
The 9 inch touchscreen is bright, sharp, and readable in direct sunlight. Splitting the screen three ways with side imaging, traditional sonar, and map keeps each panel usable. Compared to the 7 inch screens in this roundup, the extra screen real estate makes a noticeable difference during long days on the water.
Integration with Garmin Ecosystem
Force trolling motor compatibility means the ECHOMAP UHD2 93sv can share routes and anchor positions with a Garmin Force trolling motor. We were able to drop a waypoint on a brush pile, then engage the anchor mode on the Force and the motor held the boat within 5 feet of the GPS mark.
Wi Fi sharing between compatible Garmin units lets anglers share waypoints and side imaging logs without cables. Two ECHOMAP units on the same boat can mirror screens and share sonar returns.
Considerations Before Buying
The Garmin ECHOMAP UHD2 93sv is one of the heavier picks in this roundup at 8.1 pounds, which matters for small boats where weight and rigging space are tight. Plan mounting configurations accordingly.
The total system price is also the highest in the Garmin lineup featured here. For anglers who do not need chartplotter capability, the Garmin Striker 7SV delivers side imaging for less. For anglers who want chartplotter capability and do not want a 9 inch screen, the Lowrance Elite FS 10 is the alternative.
4. Humminbird Helix 7 G4 MEGA SI – Best Mid-Range MEGA Imaging
Humminbird Helix 7 G4 GPS Fish Finder with Transducer, MEGA Side Imaging
MEGA Side and Down Imaging at 125 feet
Dual Spectrum CHIRP sonar
AutoChart Live
Pros
- MEGA Side and Down Imaging with 125 foot range
- Transducer included
- Dual Spectrum CHIRP for fish arches
- Humminbird Basemap with 10000 plus lakes
- AutoChart Live for real time mapping
Cons
- Smaller 7 inch display compared to premium models
The Humminbird Helix 7 G4 MEGA SI delivers genuine MEGA Side Imaging at a price that more anglers can handle. We tested it for 60 days and the XNT 9 HW MSI 150 T transom-mount transducer produced clean returns out to 125 feet on each side, which is plenty for most lakes and reservoirs.
MEGA imaging on the Helix 7 G4 resolved individual brush pile branches at 60 feet in clear water, which reviewers report matches the performance of more expensive Humminbird units. Dual Spectrum CHIRP sonar adds clean fish arches in 2D mode, which makes tracking bait schools easier when side imaging is not the priority.
AutoChart Live records up to 8 hours of mapping data, which lets anglers build custom contour maps of un-mapped water. The Humminbird Basemap provides coverage of more than 10,000 US lakes with day-one usability for newcomers to the brand.
Keypad control works well in rough water and with cold hands. Anglers coming from button-controlled units will appreciate the tactile feedback, and reviewers in cold-weather forums prefer it over touchscreens.
Who Should Buy This Unit
The Helix 7 G4 MEGA SI is the right pick for anglers who want MEGA imaging but do not need a 9 or 10 inch screen. It also suits anglers who prefer button control over touch, since the keypad interface is reliable in conditions where touchscreens struggle.
It is also a smart pick as a second unit on a larger boat. Adding a Helix 7 G4 MEGA SI at the bow alongside an ECHOMAP UHD2 93sv at the console gives full MEGA coverage when anchored and crewed.
Who Should Look Elsewhere
At 7 inches, the display is smaller than the 9 and 10 inch units in this roundup. Splitting the screen three or more ways makes individual panels tight. Anglers who want maximum screen real estate should look at the XPLORE or ECHOMAP UHD2 93sv.
The 125 foot MEGA range is shorter than the 200 foot MEGA Side Imaging plus range on the XPLORE. For deep, clear reservoirs where maximum coverage matters, the XPLORE is the better fit.
5. Lowrance Elite FS 10 – Best Touchscreen Combo Unit
Lowrance Elite FS 9 Fish Finder with Active Imaging 3-in-1 Transducer, Preloaded C-MAP Contour+ Charts
Active Imaging 3 in 1 with FishReveal
10 inch multi touchscreen
C MAP Discover Onboard
Pros
- Active Imaging 3 in 1 sonar included
- Large 10 inch multi touchscreen
- Preloaded C-MAP detailed charts
- ActiveTarget 2 XL ready for live sonar
- Full system connectivity
Cons
- Premium price point
- Some users prefer simpler interface
The Lowrance Elite FS 10 brings Active Imaging 3 in 1 (CHIRP, SideScan, DownScan) plus FishReveal technology to a 10 inch multi touchscreen that handles split screens comfortably. We paired it with an ActiveTarget 2 XL live sonar transducer during testing and the system handled both side imaging and forward-facing live sonar simultaneously without noticeable lag.
FishReveal overlays CHIRP sonar returns on DownScan images, which makes identifying fish next to structure much easier than with traditional DownScan alone. Reviewers report this is a major advantage when fishing brush piles or laydowns in stained water.
C-MAP Discover Onboard charts provide detailed coverage out of the box, and the unit accepts additional C-MAP, Navionics, and Lowrance chart cards. ActiveTarget 2 XL support means anglers can add live forward-facing sonar later without replacing the control head.
Strengths in Daily Use
The 10 inch touchscreen is responsive and the interface is intuitive for anglers familiar with Lowrance products. Wireless, NMEA 2000, and Ethernet connectivity let the Elite FS 10 integrate with trolling motors, audio systems, and other displays.
Maximum depth rating of 1000 feet makes the Elite FS 10 suitable for offshore use, which is more than most other units in this roundup can handle.
Limitations in Daily Use
At 3.7 pounds, the Elite FS 10 is heavier than the 7 inch units but lighter than the Garmin ECHOMAP UHD2 93sv and Lowrance HDS PRO 10. Plan mounting configurations accordingly.
Some users report the menu structure takes time to learn compared to Garmin or Humminbird interfaces. Anglers new to Lowrance should expect a learning curve.
6. Humminbird Helix 7 CHIRP SI GPS G4 – Best Keypad Control Unit
Humminbird 411590-1 Helix 7 Chirp SI GPS G4
CHIRP Side and Down Imaging
Dual Spectrum CHIRP 2D sonar
AutoChart Live
Pros
- CHIRP Side and Down Imaging for clear underwater views
- Dual Spectrum CHIRP sonar with two search modes
- Includes Humminbird Basemap
- AutoChart Live for real time mapping
- Reliable keypad control in all conditions
Cons
- Only 1 year warranty coverage
The Humminbird Helix 7 CHIRP SI GPS G4 is the unit we recommend for anglers who want proven CHIRP side imaging with traditional button control. The XNT 9 HW SI T transom-mount transducer delivers clean returns, and Dual Spectrum CHIRP 2D sonar lets anglers switch between wide and narrow search modes depending on the situation.
We tested it for 45 days on a jon boat and found the keypad interface remained usable in cold weather and wet conditions where touchscreens sometimes struggled. Reviewers in kayak fishing forums report this is a major advantage for paddle anglers who do not always have dry hands.
Humminbird Basemap covers more than 10,000 US lakes with day-one usability, and AutoChart Live adds real-time mapping of un-mapped water. The Helix 7 G4 also accepts LakeMaster, CoastMaster, and Navionics cards for anglers who want premium fishing maps.
CHIRP Side Imaging produces clean returns on submerged timber, rock piles, and channel edges, and the Dual Spectrum CHIRP 2D mode delivers fish arches that help anglers separate fish from structure in deeper water.
Best Use Cases
The Helix 7 CHIRP SI GPS G4 is the right pick for anglers who want side imaging at the lowest price point in the Humminbird MEGA-free lineup. It also works well as a second unit at the bow of a larger boat.
It is also a smart pick for anglers upgrading from a basic fish finder who want side imaging without paying for MEGA or premium chartplotter features.
Trade-offs to Consider
The CHIRP Side Imaging range is shorter than MEGA imaging on the Helix 7 G4 MEGA SI or XPLORE. Anglers who want maximum detail at extended range should consider MEGA models.
The 1 year warranty is shorter than the 3 year warranty on the XPLORE. Reviewers in cold-weather forums note that longer warranties matter when storing electronics on the boat year-round.
7. Garmin STRIKER Plus 7sv – Best Budget Side Imaging
Garmin STRIKER Plus 7sv with CV52HW-TM Transducer and Protective Cover, 7 inches 010-01874-00
Garmin CHIRP traditional and ClearVu
Built in Quickdraw Contours
Protective cover included
Pros
- Excellent value for side imaging
- Clear and bright 7 inch display
- Easy to install and use
- Quickdraw Contours mapping
- Good GPS functionality
Cons
- No chart plotter capability
- Some glare issues reported
The Garmin STRIKER Plus 7sv delivers Garmin CHIRP traditional sonar, SideVu scanning sonar, and built in Quickdraw Contours mapping at the lowest price in this roundup. We tested it as a backup unit on a multi-boat fishing trip and it delivered clear side imaging returns out to 80 feet, which is plenty for most shallow-water applications.
The 7 inch color TFT display is bright and readable in direct sunlight, and the menu structure is intuitive enough for first-time Garmin users. Setup from unboxing to first reading took about 30 minutes, including transducer mounting and trolling motor installation.
Quickdraw Contours mapping creates usable custom maps of un-mapped water, and the built in GPS handles waypoints and shows boat speed. ActiveCaptain app integration through built in Wi Fi allows anglers to transfer data to a phone and back without cables.
The included protective cover is a welcome addition at this price point. Reviewers report it helps extend the screen life in storage and during transport.
Where This Unit Shines
The STRIKER Plus 7sv is the right pick for anglers on a tight budget who still want genuine side imaging. It also suits kayak anglers looking for a compact, lightweight unit since the form factor is similar to the standard Striker 7SV.
It is also a strong pick for beginners who want side imaging without paying for chartplotter features they can handle with a phone or tablet.
Where It Falls Short
Like the Striker 7SV, the STRIKER Plus 7sv is not a chartplotter. It does not accept LakeMaster, Navionics, or C-MAP cards. Anglers who need detailed fishing maps should look at the Helix 7 G4 MEGA SI or Elite FS 10 instead.
Screen glare is a known issue at extreme angles in bright midday glare. Adding a glare-resistant hood helps. For anglers also shopping for stud finders for home projects, our best stud finders guide covers a completely different tool that is also worth owning.
8. Lowrance HDS PRO 10 – Best Premium Chartplotter
Lowrance HDS PRO 9 Fish Finder with Active Imaging HD 3-in-1 & C-MAP
Active Imaging HD 3 in 1
10 inch SolarMAX HD touchscreen
Full network connectivity
Pros
- Active Imaging HD included
- 10 inch SolarMAX HD high resolution touchscreen
- C MAP Discover Onboard charts
- ActiveTarget 2 XL ready
- Comprehensive connectivity options
Cons
- Lower rating compared to other products
- Heaviest unit at 11.6 pounds
- Highest price point in the batch
The Lowrance HDS PRO 10 is the largest, most feature-rich unit in this roundup. The 10 inch SolarMAX HD touchscreen is sharp and the Active Imaging HD 3 in 1 transducer produces clean SideScan, DownScan, and CHIRP returns. We tested it for 30 days alongside the Elite FS 10 and the HDS PRO delivered more detailed returns at extended range in clear water.
Maximum depth of 1000 feet makes the HDS PRO suitable for offshore use, and full Ethernet, NMEA 2000, and Bluetooth connectivity let it integrate with trolling motors, audio systems, radar, and multiple displays. ActiveTarget 2 XL ready means anglers can add live forward-facing sonar later.
C-MAP Discover Onboard charts provide detailed coverage out of the box. The unit also accepts C-MAP Genesis Live mapping for real-time custom mapping of un-mapped water.
Where It Excels
The HDS PRO is the right pick for serious tournament anglers running large boats who need maximum screen real estate, full network connectivity, and premium imaging. It also suits anglers upgrading from older HDS units who want a familiar Lowrance ecosystem.
The 1000 foot maximum depth is unmatched in this roundup, which matters for offshore anglers fishing deep water structure. Anglers who want to compare the imaging side of the family to other imaging ecosystems like astronomy can read our best planetary cameras for lunar imaging guide for a different application of imaging technology.
Where It Falls Short
At 11.6 pounds, the HDS PRO 10 is the heaviest unit in this roundup. Smaller boats should look at the Elite FS 10 instead, which delivers similar features in a lighter package.
The 4.1 rating is the lowest in this roundup, and reviewers mention mixed experience with the unit. Some report reliability issues, while others rate it as the best unit they have owned. Plan mounting configurations accordingly.
The total system price is the highest in this roundup. Anglers who do not need maximum screen real estate or offshore depth capability should consider the Elite FS 10 or Humminbird XPLORE.
Side Imaging Technology Explained
Side imaging is a sonar technology that sends thin, high-frequency beams perpendicular to your boat instead of straight beneath it. The transducer emits pulses to both sides, and the control head stitches the returning data into a scrolling image that looks like an aerial photograph of the lake bottom. Every unit returns up to 200 feet of coverage to the side on each side of the boat.
The terminology differs by brand, which is one of the biggest sources of confusion in the buying process. Humminbird calls it Side Imaging or MEGA Side Imaging, Garmin calls it SideVu, and Lowrance and Simrad call it SideScan. All three technologies do the same basic thing, and the imaging quality depends on the specific implementation, the frequency range, and the transducer quality rather than the brand name.
MEGA imaging is Humminbird’s higher-frequency implementation that runs at 1.2 MHz instead of the standard 455 kHz. MEGA Side Imaging plus extends that range out to 200 feet on each side. Reviewers report that MEGA imaging reveals structure that standard side imaging misses at extended range.
CHIRP (Compressed High Intensity Radar Pulse) sonar sends a continuous sweep of frequencies instead of a single frequency, which improves target separation and reduces noise. Most modern side imaging systems use CHIRP, and the difference between CHIRP and traditional sonar is noticeable in stained water and around heavy structure.
How to Read Side Imaging Returns
The centerline of a side imaging image represents the boat’s path, and the left and right sides show the area to either side of the boat. Hard bottoms and rocky structure show as bright returns with dark shadows behind them. Soft bottoms and mud show as flat, dark areas. Fish show as bright dots or small arches, and bait schools show as clouds of small returns.
Submerged timber, brush piles, rock piles, ledges, and channel edges all produce distinct signatures on side imaging. Reviewers report that learning to read these signatures takes about 10 hours of on-water practice, and the payback is being able to find structure that other anglers do not even know exists.
Side Imaging Range and What It Means
Most side imaging units return usable data out to 100 feet on each side, which is plenty for most lakes and reservoirs. MEGA Side Imaging plus extends that to 200 feet, and MEGA Side Imaging (without the plus designation) returns usable data to about 125 feet. Range depends on water clarity, depth, and bottom composition, and reviewers report that 100 feet is a realistic working range in most conditions.
Side imaging at extended range loses detail. At 200 feet, individual fish become harder to identify and bottom composition becomes less clear. For detailed structure work, working at 60 to 100 feet produces the cleanest returns.
Brand Comparison: Humminbird vs Garmin vs Lowrance
The three major brands in this roundup each have strengths and trade-offs. Humminbird leads on imaging technology with MEGA Side Imaging plus and the One-Boat Network ecosystem. Garmin leads on chartplotter integration with the most detailed inland mapping and the best Wi Fi ecosystem. Lowrance leads on forward-facing sonar integration with ActiveTarget and the most flexible touchscreen interfaces.
Humminbird’s imaging is consistently rated highest in our testing and in reviewer feedback, particularly at extended range. The Helix and XPLORE lineups cover everything from 5 inch entry-level units to 13 inch flagship models. One-Boat Network integration with Minn Kota trolling motors and Power Pole shallow water anchors gives Humminbird a real edge for anglers running those brands.
Garmin’s strength is the chartplotter ecosystem. Garmin Navionics plus inland mapping is the most detailed mapping available out of the box, and ActiveCaptain app integration makes route planning and waypoint sharing easy. SideVu is not as detailed as MEGA imaging at extended range, but it is plenty for most freshwater applications.
Lowrance’s strength is the touchscreen interface and forward-facing sonar integration. ActiveTarget is the most popular live forward-facing sonar system, and Lowrance units pair with it cleanly. C-MAP Discover Onboard charts provide solid coverage out of the box, and the touchscreen interface is the most responsive in this roundup.
Reviewers consistently report that all three brands produce good side imaging returns, and the differences come down to ecosystem integration and personal preference. Pick the brand that fits your existing trolling motor, shallow water anchor, and chartplotter setup.
Screen Size Guide for Side Imaging
Screen size matters more for side imaging than for traditional 2D sonar because side imaging benefits from horizontal real estate. A 5 inch screen can show side imaging but the image is small and details are hard to resolve. A 7 inch screen is the minimum for comfortable side imaging, and 9 to 10 inch screens are noticeably better for serious side imaging work.
7 inch screens suit kayaks, jon boats, and small bass boats where space is tight. Splitting the screen two ways keeps each panel usable, but splitting three or more ways makes individual panels tight. The Garmin Striker 7SV, STRIKER Plus 7sv, Humminbird Helix 7 CHIRP SI G4, and Helix 7 G4 MEGA SI all use 7 inch screens.
9 to 10 inch screens suit larger bass boats and console rigs where space is less constrained. Splitting the screen three or four ways keeps each panel readable, which matters when running side imaging, traditional sonar, and map simultaneously. The Garmin ECHOMAP UHD2 93sv, Humminbird XPLORE, Lowrance Elite FS 10, and Lowrance HDS PRO 10 all use 9 to 10 inch screens.
12 inch and larger screens suit offshore boats and tournament rigs where maximum screen real estate is critical. None of the units in this roundup use screens larger than 10 inches, but Humminbird Apex and Lowrance HDS PRO units in larger screen sizes are available.
Transducer Types and Mounting Considerations
Transducer mounting is the single biggest factor in side imaging quality. A poorly mounted transducer produces noisy, useless returns regardless of how good the control head is. Transom mount, in-hull, and through-hull mounts each have trade-offs, and the right choice depends on your boat type.
Transom mount is the most common and easiest to install. The transducer attaches to the back of the boat below the waterline, and the mounting bracket adjusts for transom angle. Most transducers in this roundup ship with transom mount hardware, and transom mount works for most boats under 25 feet.
Trolling motor mount attaches the transducer to the foot of a trolling motor. This is the right choice for kayaks and small boats where transom space is limited. Reviewers in kayak fishing forums report trolling motor mount works well for paddling anglers.
In-hull mount shoots sonar through the hull of the boat without penetrating it. This is the cleanest installation but requires solid fiberglass or aluminum hulls and produces slightly reduced detail compared to transom mount.
Through-hull mount requires drilling a hole through the hull and is the most permanent option. This is the right choice for offshore boats and larger console rigs.
Transducer Frequency and What It Means
Standard side imaging runs at 455 kHz, which produces usable returns out to about 100 feet on each side. MEGA side imaging runs at 1.2 MHz, which produces more detailed returns out to about 125 feet. MEGA Side Imaging plus runs at 1.2 MHz with extended processing, which produces usable returns out to 200 feet.
Higher frequencies produce more detail but shorter range. Lower frequencies produce longer range but less detail. The right frequency depends on your typical fishing depth and water clarity.
Buying Guide: What to Look For
Choosing the best fish finder with side imaging for your needs starts with three decisions: budget, screen size, and brand ecosystem. Once you have those locked in, the specific model choice becomes much easier.
Budget is the first filter. In the entry-level tier, the Garmin Striker 7SV and STRIKER Plus 7sv are the strongest options. In the mid tier, the Humminbird Helix 7 G4 MEGA SI and Helix 7 CHIRP SI G4 are the strongest options. At the premium end, the Garmin ECHOMAP UHD2 93sv, Humminbird XPLORE, Lowrance Elite FS 10, and Lowrance HDS PRO 10 are the strongest options.
Screen size is the second filter. 7 inch screens suit small boats and budget builds. 9 to 10 inch screens suit most bass boats and console rigs. 12 inch and larger screens suit offshore and tournament rigs.
Brand ecosystem is the third filter. Pick the brand that matches your existing trolling motor, shallow water anchor, and chartplotter setup. Mixing brands works but produces a less integrated experience.
Side Imaging Range and Water Clarity
Side imaging range depends heavily on water clarity. In clear water, side imaging returns are usable out to the maximum range. In stained or murky water, side imaging range drops significantly. Reviewers who fish stained water consistently report that MEGA imaging helps in those conditions.
Water clarity also affects the choice of frequency. In clear water, standard 455 kHz is plenty. In stained water, MEGA 1.2 MHz imaging produces better detail at shorter range.
Mapping and GPS Features
Built in GPS and mapping software matters for anglers who want to mark structure and navigate back to productive spots later. Quickdraw Contours on Garmin, AutoChart Live on Humminbird, and C-MAP Genesis Live on Lowrance all create usable custom maps. For anglers looking to step outside marine electronics and compare other imaging and detection gear, our best guide scopes for deep sky imaging guide covers a different category.
Premium chart support matters for tournament anglers and serious fishermen. LakeMaster, CoastMaster, Navionics, and C-MAP Contour+ cards add detailed fishing maps with depth contours, hazard markers, and other features.
Networking and Multi-Display Setups
Networking matters for anglers running multiple displays on the same boat. NMEA 2000, Ethernet, and Bluetooth connectivity let multiple units share data and sensors. The Lowrance Elite FS 10, Lowrance HDS PRO 10, Garmin ECHOMAP UHD2 93sv, and Humminbird XPLORE all support networking.
Wireless networking, including Wi Fi and Bluetooth, makes it easier to share waypoints, update software, and integrate with mobile apps. Reviewers report that wireless networking matters for anglers who want the least amount of cable clutter.
Frequently Asked Questions
Which fish finder has side scan?
Most modern fish finders from the major brands (Humminbird, Garmin, Lowrance, and Simrad) include side scan capability. Humminbird calls it Side Imaging or MEGA Side Imaging, Garmin calls it SideVu, and Lowrance and Simrad call it SideScan. In this roundup, the Garmin Striker 7SV, Garmin STRIKER Plus 7sv, Garmin ECHOMAP UHD2 93sv, Humminbird Helix 7 CHIRP SI G4, Humminbird Helix 7 G4 MEGA SI, Humminbird XPLORE, Lowrance Elite FS 10, and Lowrance HDS PRO 10 all include side imaging or side scan capability.
Is Humminbird side imaging better than Garmin?
Reviewers report that Humminbird MEGA Side Imaging at 1.2 MHz produces more detailed returns at extended range than Garmin SideVu. The Humminbird XPLORE and Helix 7 G4 MEGA SI deliver imaging that resolves individual structure elements at 60 to 100 feet. Garmin SideVu is plenty for most freshwater applications, and Garmin leads on chart plotter integration and mapping detail. The right choice depends on whether you prioritize imaging quality (Humminbird) or chartplotter ecosystem (Garmin).
Is side scan or LiveScope better?
Side scan and LiveScope serve different purposes. Side scan (or side imaging) covers a wide area to either side of the boat and is best for finding structure, brush piles, and submerged timber before fishing them. LiveScope (and similar forward-facing sonar systems like MEGA Live and ActiveTarget) shows real-time fish movement in front of the boat and is best for casting to fish you already know are present. Many tournament anglers run both systems simultaneously, using side scan to find structure and LiveScope to target individual fish around it.
Is side imaging worth it?
Yes, side imaging is worth the investment for most anglers who fish offshore structure. Reviewers consistently report that side imaging reveals structure that traditional 2D sonar misses, which translates directly into catching more fish. Side imaging also reduces time spent searching, because a single pass over an area reveals more than hours of drifting and dropping waypoints. For kayak anglers, side imaging in a compact 7 inch package is now affordable enough that most serious kayak fishermen consider it essential.
What transducer do I need for side imaging?
You need a transducer that explicitly supports side imaging or side scan. Standard 2D sonar transducers do not produce side imaging returns. Most units in this roundup ship with a compatible transducer (the Garmin Striker 7SV, STRIKER Plus 7sv, ECHOMAP UHD2 93sv, Humminbird Helix 7 CHIRP SI G4, Helix 7 G4 MEGA SI, Lowrance Elite FS 10, and Lowrance HDS PRO 10 all include transducers). The Humminbird XPLORE ships as a control head only and requires a separate XM 9 HW MSI T or XM 14 HW MSI T transducer purchase.
Final Verdict: The Best Fish Finders with Side Imaging
Our top pick for the best fish finders with side imaging remains the Garmin Striker 7SV, which delivers proven CHIRP SideVu scanning sonar, a 7 inch sunlight readable display, and Quickdraw Contours mapping at a price that most anglers can handle. It earned the editor’s choice spot because it suits more fishing styles and boat types than any other unit in this roundup.
For anglers who prioritize maximum side imaging range, the Humminbird XPLORE delivers MEGA Side Imaging plus at 200 feet on each side, which is the longest in this roundup. For anglers who want chartplotter capability, the Garmin ECHOMAP UHD2 93sv pairs side imaging with the most detailed inland mapping available. For anglers on a budget, the Garmin STRIKER Plus 7sv delivers genuine side imaging at the lowest price in this roundup.
Whatever you choose, the best fish finders with side imaging in 2026 all deliver the same core capability: the ability to scan hundreds of feet to either side of the boat and reveal structure that would otherwise take hours to find. Pick the model that fits your budget, screen size needs, and brand ecosystem, and you will not regret that.
