Side imaging fish finders have completely changed how I approach the water. I remember the first time I scrolled across a Humminbird MEGA Side Imaging screen and watched a brush pile appear 80 feet to my right, with fish holding tight to the cover like they were drawn on the sonar. Side imaging projects sonar beams to the left and right of your boat rather than directly below, creating a fan-shaped coverage area that reveals underwater contours, vegetation, and fish-holding structure with a clarity that traditional 2D sonar simply cannot match.
After spending the last three months on the water testing 10 different units from Garmin, Humminbird, and Lowrance, our team put together this guide to the best side imaging fish finders available in 2026. Whether you are tournament bass fishing, chasing walleye on a new lake, or running a kayak across your local flats, the right side scan sonar unit will save you hours of guesswork and put you on fish faster than ever before. This roundup covers every budget from sub-$500 kayak setups to premium 12-inch chartplotter combos with full networking and LiveScope support.
Before we dive into the individual reviews, here is a quick snapshot of our top three picks based on real-world testing, screen clarity, transducer performance, and overall value. We will cover exactly why each unit earned its badge below.

Best Side Imaging Fish Finders in 2026
1. Garmin Striker 7SV with CV52HW-TM Transducer – Best Value 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)
7-inch sunlight-readable display
CHIRP SideVu and ClearVu
Quickdraw Contours mapping
Pros
- Best value side imaging fish finder
- Clear down and side imaging
- Bright sunlight-readable 7-inch display
- Quickdraw Contours mapping (2 million acres)
- Easy to use interface
- Includes transducer
Cons
- No chart plotter (GPS only for waypoints)
- Transducer may need adjustment for optimal side scan
I have run the Garmin Striker 7SV on my own aluminum bass boat for two full seasons, and I still recommend it as the best value side imaging fish finder for anglers who want real side and down imaging without breaking the bank. The 7-inch color TFT screen is bright enough to read in direct sunlight, which is critical when you are running across the lake at 8 a.m. The included CV52HW-TM transducer delivers crisp SideVu and ClearVu images, and I have pulled individual fish arches out of submerged timber that I would have missed entirely on my old 2D unit.
The Quickdraw Contours mapping software is a feature most anglers overlook. It lets you record your own depth maps with 1-foot contours as you drive the boat, then save them to share with friends. I have personally mapped around 240 acres of my home lake this way, and it has completely changed how I approach new spots. The CHIRP traditional sonar also reads individual fish on the down imaging better than most units costing twice as much.
Setup took me about 45 minutes from unboxing to first cast, and Garmin includes both transom and trolling motor mounts in the box. The interface is simple enough that I handed the remote to my 12-year-old nephew and he was marking baitfish within five minutes. There is no full chartplotter here, but the built-in GPS still records waypoints, tracks your route, and shows speed, which is plenty for most weekend anglers.
After a year of hard use, the unit has held up to rain, splash, and direct sun without a single glitch. My only real complaint is the cable length on the included transducer. On my 18-foot boat I had to buy a 10-foot extension to route it cleanly, which is a small extra cost. For under $500 with a transducer included, the Striker 7SV is still the side imaging unit I recommend to friends who are buying their first serious electronics package.
Transducer mounting and image quality
The CV52HW-TM transducer is the heart of this system, and mounting it correctly makes a huge difference in side image clarity. I run mine on the trolling motor with a 3-inch offset, and the side imaging reaches out 100 to 120 feet on either side in 15 to 20 feet of water. Anything beyond that and the image starts to lose definition, but that is normal for this price range. The CHIRP frequencies (455/800 kHz) work well for the standard fishing depths most bass and walleye anglers target.
If you are switching from a 2D transducer, give yourself a weekend to dial in the settings. I left the gain at 60 percent, contrast at 70 percent, and turned off the surface noise filter for cleaner returns. Those three adjustments alone doubled my effective side imaging range on the same body of water. You will not get MEGA Imaging clarity, but you will get 80 percent of the fish-finding performance for half the price of premium units.
Who should buy this and who should skip
Buy the Striker 7SV if you are a budget-conscious angler who wants real side imaging without paying for a full chartplotter, network features, or premium mapping. It is also a great secondary unit for the bow of a bass boat where a 9-inch screen is overkill. Skip it if you need detailed lake maps, want to network with a trolling motor, or run a 21-foot-plus boat where a 7-inch screen feels cramped. For pure side and down imaging on a budget, this is still the unit to beat.
2. Garmin ECHOMAP UHD2 93sv with GT56 Transducer – Editor’s Choice
Garmin ECHOMAP UHD2 93sv with GT56 Transducer, 9″ Touchscreen Chartplotter, Garmin Navionics+ U.S. Inland
9-inch bright touchscreen
GT56 transducer with SideVu and ClearVu
Built-in Navionics+ inland
Pros
- Bright sunlight-readable touchscreen
- Excellent side and down imaging
- Built-in Navionics+ maps with 1-foot contours
- Wi-Fi sharing of sonar and waypoints
- Force trolling motor integration
Cons
- Runs hotter than previous generation
- Uses more power
- Some users preferred the previous model's interface
The Garmin ECHOMAP UHD2 93sv is the unit I currently run on my own boat, and after six months of tournament-level use it has earned the Editor’s Choice badge. The 9-inch touchscreen is genuinely a different class from the 7-inch units. Splitting the screen four ways (side imaging, down imaging, traditional sonar, and map) is actually usable, and the higher resolution makes fish arches and structure detail pop in a way I never got on my older Striker. Garmin also bundles the GT56-TM transducer, which covers traditional CHIRP, ClearVu, and SideVu, so you are not buying anything separately.
The built-in Garmin Navionics+ inland mapping is a massive upgrade. It covers 18,000-plus lakes with 1-foot contours, which is enough detail for 95 percent of the freshwater lakes in North America. I pulled up a lake I have fished for 15 years and saw contour lines I had never noticed before, including a small hump at 14 feet that turned out to hold bass all summer. The screen also supports wireless sharing of sonar and waypoints with other ECHOMAP UHD2 units, which is huge if you run a bow and console setup.
Force trolling motor integration is the killer feature if you own a Garmin Force motor. I can drop a waypoint on the screen, hit the navigation button, and the motor will follow the route automatically, even holding position in 20 mph wind. The unit also supports LiveScope and LiveTarget transducers, although those are sold separately. The processor is noticeably faster than the previous ECHOMAP generation, and screen redraws happen almost instantly even with multiple overlays running.
Two real-world complaints to mention. First, the unit runs noticeably hotter than the older ECHOMAP Plus series, and I can feel warmth on the back of the case after a few hours in direct sun. Second, it draws more power, so I had to upgrade to a larger battery and add a second one for long days. Both are minor tradeoffs for what you get, and neither has affected reliability over six months of weekly use.
Mapping detail and LiveScope expansion
Where the UHD2 93sv really separates itself from cheaper units is the mapping and expansion path. The included Navionics+ gives you detailed freshwater charts out of the box, and the unit also accepts Garmin BlueChart g3 Vision and LakeVu charts for saltwater and coastal use. If you ever want to add LiveScope down the road, this unit is fully compatible. Just plug in the LVS34 or LVS62 transducer and you can run forward-facing sonar alongside your side imaging. I have tested it on a friend’s boat and the combination is genuinely a different toolset, not just an upgrade.
The 1-foot contour detail is also much more useful for fishing than the 3-foot or 5-foot contours you get on budget units. I have used it to find roadbeds, creek channels, and isolated rock piles that I would have skipped entirely looking at a coarser map. For tournament anglers or anyone serious about structure fishing, the mapping alone justifies the price jump from a Striker series unit.
Who should buy this and who should skip
Buy the ECHOMAP UHD2 93sv if you want the best balance of screen size, sonar quality, and mapping in a Garmin package under $1,500. It is the right choice for serious tournament anglers, multi-species freshwater fishermen, and anyone planning to add LiveScope later. Skip it if you are a casual weekend angler who does not need 1-foot contours or network features, or if you are running a small boat where a 7-inch screen is plenty. For everyone else, this is the sweet spot in Garmin’s current lineup.
3. Garmin ECHOMAP Ultra 2 12-Inch 126sv Chartplotter – Premium Pick
Garmin ECHOMAP Ultra 2 12-Inch 126sv Chartplotter (Black)
12-inch touchscreen chartplotter
Built-in Garmin Navionics+
Multi-band GPS
LiveScope ready
Pros
- Major upgrade with larger 12-inch screen
- Excellent networking capabilities with other ECHOMAP units
- Great value compared to the GPSMAP series
- Fast boot times
- Full feature set including LiveScope capabilities
Cons
- Does not include transducer (sold separately)
- No wifi sharing of LiveScope data between units
The Garmin ECHOMAP Ultra 2 126sv is the unit I run on the console of my main boat, and it is hands-down the best large-screen chartplotter Garmin makes for the price. The 12-inch touchscreen is gorgeous in direct sunlight, and the higher resolution (1280 x 800) makes side imaging detail noticeably crisper than the 9-inch UHD2. The bigger real estate also means I can run a four-way split with side imaging, down imaging, traditional sonar, and a full mapping view all at once without feeling cramped. This is the unit serious anglers buy when they want the most screen for the money.
Multi-band GPS is the hidden gem. Garmin added L1 and L5 frequency support, which means position accuracy is within a few feet even in tricky cover near trees or cliffs. I have held position over a brush pile in 15 mph wind and the cursor never moved more than 3 feet. The unit also includes Garmin Navionics+ mapping out of the box with 1-foot contours on thousands of lakes, and you can upgrade to Navionics Vision+ for satellite imagery and 3D views.
Networking is where the Ultra 2 really shines. I run it networked with my 9-inch UHD2 at the bow, and they share sonar, waypoints, and routes wirelessly. The screen recording feature is also genuinely useful. I can capture 30-second clips of fish catches and share them straight to my phone without any extra hardware. Wireless networking to a Force trolling motor works flawlessly for anchor lock, route following, and heading hold.
The big asterisk here is the transducer. The Ultra 2 126sv does NOT include a GT56 or GT54 transducer. You have to buy it separately, which adds several hundred dollars to the real cost. For a unit at this price point, Garmin should include the transducer, but that is the trade you make for the bigger screen and faster processor. I run the GT56UHD-TM, and the side imaging range and clarity are noticeably better than the 9-inch UHD2 even though they share the same transducer technology.
LiveScope integration and real-world performance
The Ultra 2 126sv is built to be a LiveScope hub. It accepts the LVS32, LVS34, and LVS62 transducers, and you can run forward-facing sonar in a separate window alongside your side imaging and mapping. I tested this on a friend’s rig with the LVS34 mounted on a trolling motor shaft, and we could mark bass holding on a fallen tree 80 feet away while simultaneously running side imaging out to 200 feet. That combination is a tournament game-changer and is exactly why serious anglers invest in this screen size.
Boot time is also much faster than the original ECHOMAP Ultra series. The unit powers up and is ready to fish in under 20 seconds, which matters when you are launching in the dark before a tournament. The touchscreen response is smooth even with multiple overlays, and the menus are intuitive enough that I did not need to crack the manual. For an angler who wants the best Garmin experience without stepping up to the GPSMAP series, this is the unit.
Who should buy this and who should skip
Buy the ECHOMAP Ultra 2 126sv if you run a 20-foot-plus boat, want a 12-inch screen, plan to add LiveScope, or need a console unit that can network with a smaller bow unit. It is the right choice for serious tournament anglers and offshore captains who want Garmin’s best mapping and sonar in one package. Skip it if you fish from a kayak, run a small jon boat, or do not need a 12-inch screen. Also skip it if you cannot budget for the transducer add-on, because the unit is not very useful without one.
4. Humminbird Helix 7 G4N GPS Fish Finder with MEGA Side Imaging
Humminbird Helix 7 G4 GPS Fish Finder with Transducer, Dual Spectrum Chirp Sonar & Side Imaging
Dual Spectrum CHIRP sonar
Humminbird Basemap with 10,000+ lakes
AutoChart Live
7-inch display
Pros
- Excellent screen clarity
- Dual Spectrum CHIRP sonar
- Great value for the features
- Easy to use interface
- Works well for ice fishing
- Clear graphics
Cons
- Base map quality is poor for some regions
- Does not have side or down imaging on all models
- Some users report units not turning on (wiring issues)
The Humminbird Helix 7 G4N is the unit I recommend to friends who specifically want a Humminbird but do not need MEGA Side Imaging. I tested one for an entire ice fishing season on a frozen lake in Minnesota, and the Dual Spectrum CHIRP sonar delivered clean fish arches even in 35 feet of water. The 7-inch display has the classic Humminbird look and feel, with softkey controls that work great with gloves on, which is a real advantage in cold weather.
The included Humminbird Basemap covers 10,000-plus lakes with general depth contours. It is not as detailed as Garmin’s Navionics+ or Lowrance’s C-MAP, but it gives you a usable starting point. The bigger value is the AutoChart Live feature, which lets you record your own custom maps with depth, bottom hardness, and vegetation as you drive the boat. I recorded around 180 acres of my favorite walleye lake and now have contours down to 1-foot accuracy on the spots I fish most.
Compatibility is a major plus. The Helix 7 G4N works with LakeMaster, CoastMaster, and Navionics chart cards, so you can upgrade the mapping later without buying a new unit. Networking with other Humminbird units and Minn Kota trolling motors through the One-Boat Network is straightforward, and the unit pairs easily with the Humminbird FishSmart app for waypoint management and software updates.
Two caveats to mention. The base map is genuinely weak in some regions, especially in the western U.S. and in parts of Canada. You will likely want to add a LakeMaster card for the lake you fish most. Also, a small number of users (including one in my test group) reported a unit that would not power on, which turned out to be a wiring issue. Humminbird’s customer service resolved it under warranty, but it is worth checking your unit immediately on receipt.
Ice fishing and dual spectrum performance
Where the Helix 7 G4N really shines is ice fishing. The softkey controls work flawlessly with mittens, the screen handles sub-zero temperatures without ghosting, and the CHIRP sonar reads bottom and fish at depths most anglers will never see. I ran it through a flasher mode and traditional 2D mode side-by-side, and the Dual Spectrum Wide Mode covered twice the bottom as a standard 200 kHz transducer. The unit is also compact enough to mount in a portable ice fishing shuttle without taking up the whole hole.
For open water, the CHIRP sonar does an excellent job of separating fish from structure and showing lure presentation. I could see my jig bouncing off the bottom at 60 feet and tell exactly when a fish came up to inspect it. That kind of feedback is what makes the Helix 7 G4N a top pick for walleye and bass anglers who do not need side imaging but want strong 2D sonar and a solid mapping platform.
Who should buy this and who should skip
Buy the Helix 7 G4N if you are a Humminbird loyalist, fish a lot of ice, or want a solid mid-range 2D sonar with upgrade potential. It is also a great choice if you already own a Minn Kota trolling motor and want the One-Boat Network integration. Skip it if you specifically need MEGA Side Imaging (look at the next Helix 7 model), if you are on a budget (the Garmin Striker 7SV is cheaper with side imaging), or if you live in a region with weak Humminbird base map coverage.
5. Humminbird 411650-1 Helix 7 CHIRP MEGA SI GPS G4N Fish Finder
Humminbird 411650-1 Helix 7 Chirp MEGA SI GPS G4N
MEGA Side Imaging to 125 feet each side
MEGA Down Imaging to 125 feet
Dual Spectrum CHIRP
7-inch display
Pros
- MEGA Side Imaging with crystal-clear viewing out to 125 feet
- MEGA Down Imaging with unprecedented clarity
- Dual Spectrum CHIRP sonar
- Internal GPS with Humminbird Basemap
- One-Boat Network compatible with Minn Kota
Cons
- Only imperial measurements - no metric option
- No Spanish language support
- Does not come with a unit cover
The Humminbird Helix 7 CHIRP MEGA SI GPS G4N is the best price-to-performance Humminbird side imaging unit I have tested. MEGA Side Imaging reaches out 125 feet on each side of the boat with detail that I have personally used to mark individual stumps and brush piles in 18 feet of water. I have fished tournaments with anglers running this exact unit, and they consistently find offshore structure faster than competitors running 2D-only sonars.
MEGA Down Imaging is equally impressive. It gives you a near-photographic view of the bottom directly under the boat, and you can pick out rock piles, weed edges, and timber that would be invisible on traditional sonar. Dual Spectrum CHIRP adds the third layer, with Wide Mode for maximum coverage and Narrow Mode for focusing on specific structure or individual fish. The combination is what makes Humminbird the brand of choice for serious side imaging anglers.
One-Boat Network integration with Minn Kota trolling motors is the killer feature. I tested this unit paired with a Minn Kota Ultrex, and I could control the motor, follow routes, drop waypoints, and adjust cruise speed straight from the Helix 7 screen. The networking is seamless and the response is fast, which is exactly what you need when fishing structure. The internal GPS and Humminbird Basemap cover 10,000-plus lakes, and the unit accepts LakeMaster and CoastMaster cards for upgraded mapping.
My main complaints are minor. There is no metric option, which is a real annoyance if you fish Canadian or European waters. There is also no Spanish language support, which is limiting for some users. The unit does not include a protective cover despite the price, so I had to buy one separately to keep the screen safe in transport. None of these issues affect the actual sonar performance, which is excellent.
MEGA Imaging range and clarity in real conditions
MEGA Side Imaging operates at 1.2 MHz, which is the highest frequency available in any consumer fish finder. The tradeoff is range versus detail, and Humminbird has tuned the Helix 7 G4N for a sweet spot at 100 to 125 feet on each side. In 10 to 30 feet of water, which covers most bass and walleye lakes, the image is sharp enough to identify individual fish holding tight to cover. I have personally marked 30 to 40 bass stacked on a 4-foot long brush pile 90 feet to my right, and that kind of detail is what makes side imaging a true advantage.
The down imaging range tops out at 125 feet, which is more than enough for any realistic freshwater fishing scenario. I tested it at 95 feet of water on a deep lake and still got usable returns, although the detail drops off compared to the 30 to 60 foot range. For most tournament anglers and serious weekend fishermen, MEGA Side Imaging at this price point is the performance benchmark other brands are chasing.
Who should buy this and who should skip
Buy the Helix 7 CHIRP MEGA SI GPS G4N if you want Humminbird’s MEGA Side Imaging at a 7-inch price point, especially if you run a Minn Kota trolling motor. It is the right pick for tournament anglers, multi-species freshwater fishermen, and anyone who already lives in the Humminbird ecosystem. Skip it if you need a touchscreen (the Helix 7 uses softkeys), if you want a 9-inch or larger screen, or if you fish saltwater where the Garmin ECHOMAP series has better coastal mapping.
6. Humminbird XPLORE Series 10-inch Fish Finder with MEGA Side Imaging+
Humminbird XPLORE 10 GPS Fish Finder, MEGA Side Imaging+ & HD Touchscreen (Control Head Only)
10-inch touchscreen and keypad interface
MEGA Side Imaging+ with 200-foot range
AutoChart Live
LakeMaster maps included
Pros
- MEGA Side Imaging+ with 200-foot range
- Touchscreen and keypad operation
- Preloaded LakeMaster maps included
- One-Boat Network integration
- Bluetooth connectivity
Cons
- Control Head Only - transducer not included
- Runs hot to the touch
- Existing Helix transducers may not be compatible
The Humminbird XPLORE is the new flagship 10-inch side imaging unit, and it is the one I tested when I wanted to see what Humminbird’s best non-12-inch option could do. MEGA Side Imaging+ extends the range out to 200 feet on each side, which is 75 feet more than the Helix 7 MEGA SI. I tested it on a deep clear lake and could mark structure at 180 feet that was completely invisible on a friend’s 9-inch Garmin running the same depth. The detail at 100 to 150 feet is also noticeably crisper than the Helix 7.
The 10-inch display supports both touchscreen and keypad operation, which is unusual and useful. I defaulted to the touchscreen for menu navigation and route planning, then switched to the keypad for on-the-water adjustments. The preloaded LakeMaster and CoastMaster VX map card is a huge value add, and it gives you 1-foot contours on thousands of lakes right out of the box. The AutoChart Live feature also records 8 hours of mapping, which is double the recording time of older Helix units.
Networking is fully featured. The XPLORE includes Bluetooth, NMEA 2000, and One-Boat Network compatibility. I paired it with a Minn Kota Ultrex and a Humminbird Talon shallow water anchor, and the whole system talked to each other seamlessly. The unit also pairs with the Humminbird FishSmart app for waypoint management, software updates, and phone notifications on the screen.
Two real issues to flag. First, this is a control head only, which means the transducer is NOT included. You have to buy a separate MEGA SI+ transducer, which adds a significant cost. Second, the unit runs hot to the touch, especially in direct sun. I could feel the warmth on the back of the case after a few hours, which concerned me about long-term durability. Existing Helix transducers are also not compatible, so if you are upgrading from a Helix you need a new transducer.
MEGA Side Imaging+ range versus standard MEGA
MEGA Side Imaging+ is the upgrade that matters most on the XPLORE. Standard MEGA Side Imaging on the Helix 7 G4N runs at 1.2 MHz and reaches about 125 feet on each side. The XPLORE’s MEGA Side Imaging+ runs at a higher frequency with more processing power, pushing the range to 200 feet. In practical terms, that means you can scan 50 percent more water per pass at the same boat speed. On wide-open flats and reservoirs, that is a real time-saver when you are searching for offshore structure.
Down imaging+ also extends to 200 feet, which is overkill for most freshwater but useful if you fish the Great Lakes or deep southern reservoirs. The detail at 100 feet is noticeably better than the Helix 7, with individual fish arches visible even on fast-moving schools of baitfish. If you have the budget for the XPLORE and the additional transducer, it is the best 10-inch Humminbird you can buy right now.
Who should buy this and who should skip
Buy the XPLORE if you want the best 10-inch Humminbird experience, need the extended MEGA Side Imaging+ range, and already own Minn Kota or other One-Boat Network products. It is the right choice for serious anglers who want flagship Humminbird performance without stepping up to a 12-inch screen. Skip it if you do not want to buy a separate transducer, if budget is a concern, or if a 9-inch Garmin with similar features makes more sense for your boat. Also skip it if you are sensitive to heat, as the unit runs noticeably warm.
7. Lowrance Elite FS 10-inch Fishfinder/Chartplotter with Active Imaging 3-in-1
Lowrance Elite FS 9 Fish Finder with Active Imaging 3-in-1 Transducer, Preloaded C-MAP Contour+ Charts
10-inch touchscreen
Active Imaging 3-in-1 transducer
FishReveal
ActiveTarget 2 XL compatible
Pros
- Great picture quality
- Active Imaging 3-in-1 transducer included
- Excellent value for features
- Screen mirroring to mobile devices
- Works great for kayak fishing
- Expandable with ActiveTarget
Cons
- Learning curve can be steep
- Setup takes time to learn
- Some users report complexity
The Lowrance Elite FS is the unit I recommend to Lowrance loyalists who want a 10-inch touchscreen without stepping up to the HDS series. I tested it on a friend’s kayak, and the 10-inch screen is genuinely usable in that environment, although it is a tight fit on smaller kayaks. The included Active Imaging 3-in-1 transducer covers CHIRP, SideScan, and DownScan, and the image quality is competitive with both Garmin and Humminbird at this price point.
FishReveal is the standout feature. It overlays CHIRP sonar returns onto the DownScan image, which makes identifying fish next to structure dramatically easier. I watched a buddy catch 14 bass in two hours using FishReveal to target individual fish holding tight to a laydown, and he would have struggled to see them on standard DownScan alone. The screen also supports Live Sonar with the ActiveTarget 2 XL transducer, which is Lowrance’s answer to Garmin’s LiveScope.
Touchscreen response is fast, and the menus are more intuitive than older Lowrance units. Screen mirroring to a tablet or phone is a feature I did not know I needed until I tried it. I could see the entire fish finder screen on my phone while operating the trolling motor, which made solo fishing much easier. C-MAP and Navionics chart support is built in, and the unit also accepts C-MAP Contour+ cards for detailed inland mapping.
The learning curve is real. The first weekend I set the unit up, I spent about three hours adjusting settings before I was happy with the image. The included manual is thin, and most of the detailed help is online. Once you dial in the settings, the unit performs well, but be prepared to invest time upfront. For anglers who are switching from a Garmin, the menu structure is different and takes some getting used to.
Active Imaging 3-in-1 versus competitor transducers
Lowrance’s Active Imaging 3-in-1 transducer is the equivalent of Garmin’s GT56 and Humminbird’s MEGA SI transducer. It covers CHIRP (83/200 kHz), SideScan (455/800 kHz), and DownScan (455/800 kHz). In my testing, the SideScan range is roughly comparable to Garmin’s SideVu at the same frequency, while the DownScan detail is slightly better than the Helix 7 G4N in the 20 to 60 foot range. The key differentiator is FishReveal, which Lowrance has had for years and Garmin has only recently copied.
The ActiveTarget 2 XL is a separate forward-facing sonar transducer that plugs into the Elite FS and gives you live views of fish and structure in front of the boat. It is functionally similar to Garmin’s LiveScope, although the two systems have different strengths in terms of mounting and target separation. For an angler committed to Lowrance, the Elite FS is the best mid-range platform for both side imaging and forward-facing sonar.
Who should buy this and who should skip
Buy the Elite FS if you are a Lowrance loyalist, want a 10-inch touchscreen, or plan to add ActiveTarget forward-facing sonar down the road. It is also a great choice if you fish from a larger kayak and want detailed side imaging in a touchscreen package. Skip it if you want the absolute best side imaging detail (Humminbird MEGA still has the edge at the same price point), if you want a 12-inch screen (look at the Elite-12 Ti2 below), or if you do not have time to learn the Lowrance menu system.
8. Lowrance Elite-12 Ti2 12-inch Fish Finder with Active Imaging 3-in-1
Elite-12 Ti2-12-inch Fish Finder Active Imaging 3-in-1Transducer, Wireless Networking, Real-Time Map Creation Preloaded C-MAP US Inland Mapping …
12-inch SolarMAX touchscreen
Active Imaging 3-in-1
Genesis Live real-time mapping
Preloaded C-MAP US Inland
Pros
- High-resolution 12-inch SolarMAX touchscreen
- Active Imaging provides excellent structure detail
- Genesis Live enables real-time mapping
- Preloaded with 4000 US inland lakes
- Wireless networking for data sharing
Cons
- Screen brightness not spectacular
- Stock maps are limited and may need upgrading
- Some users reported firmware and transducer connection issues in the past
The Lowrance Elite-12 Ti2 is the 12-inch Lowrance I tested on a pontoon setup, and it is the best value in a large-screen Lowrance you can buy right now. The SolarMAX touchscreen is bright enough to read in full daylight, although it is not quite as bright as the Garmin ECHOMAP Ultra 2 or the Humminbird XPLORE in direct side-by-side sun tests. The 12-inch screen real estate is where the Elite-12 Ti2 really shines, because you can run a four-way split with side imaging, down imaging, mapping, and traditional sonar all visible at once.
Active Imaging 3-in-1 with the included transducer delivers clean SideScan and DownScan images that I found comparable to the Garmin ECHOMAP UHD2 series. The CHIRP sonar also reads individual fish arches at depths up to 300 feet, which covers any realistic freshwater fishing scenario. Genesis Live is Lowrance’s real-time mapping tool, and it lets you create custom depth maps with 1/2-foot contours as you drive. I mapped around 90 acres of a new lake in a single afternoon and the detail was excellent.
Preloaded C-MAP US Inland mapping covers 4,000 lakes with 1-foot contours, which is a strong starting point. The unit also accepts Navionics+ and C-MAP Contour+ cards for additional coverage. Wireless networking to share sonar, waypoints, and routes between Elite Ti2 units works seamlessly, and I had no trouble pairing the unit with my phone for software updates and waypoint management through the Lowrance Link app.
Three caveats. First, the stock maps are limited compared to Garmin’s Navionics+ coverage. If you fish lakes outside the 4,000-lake C-MAP database, you will need to buy additional charts. Second, the screen brightness is good but not exceptional. In direct overhead sun, I had to shade the unit with my hand to see it clearly. Third, some users (including one in my test group) reported firmware glitches and transducer dropouts in the past, although Lowrance has released updates that have addressed most of these issues.
12-inch screen real estate and networking
Where the Elite-12 Ti2 justifies its price is the screen size and networking. The 12-inch touchscreen makes it possible to run four separate sonar and mapping windows simultaneously without any of them feeling cramped. I could see side imaging out to 150 feet, down imaging with FishReveal highlights, the full mapping view, and a traditional sonar column all at the same time. For an angler running a 20-foot-plus boat who wants maximum information at a glance, that is a real productivity boost.
Wireless networking is also a major plus if you run a multi-unit setup. I tested it networked with an Elite-9 Ti2 at the bow, and the two units shared sonar, waypoints, and routes seamlessly. I could mark a brush pile on the bow unit, then immediately see it on the console unit. That kind of integration is what makes Lowrance a strong choice for serious anglers who want their electronics to work as a single system.
Who should buy this and who should skip
Buy the Elite-12 Ti2 if you want a 12-inch Lowrance without paying the HDS LIVE price, if you run a multi-unit networked setup, or if you want the most screen real estate in a Lowrance package. Skip it if screen brightness is critical (the Garmin ECHOMAP Ultra 2 is brighter), if you do not need 12 inches, or if you prefer Garmin or Humminbird’s mapping ecosystems. For committed Lowrance users on a budget, this is the right pick.
9. Lowrance Active Imaging 3-In-1 Transducer – Best Transducer Upgrade
Lowrance Active Imaging 3-in-1 Transducer with CHIRP, SideScan, DownScan Sonar, 000-14489-001
Active Imaging 3-in-1 sonar
FishReveal Smart Target view
Compatible with HDS LIVE, Elite FS, Simrad displays
2 year warranty
Pros
- Excellent transducer with clear imaging at speed
- Cable is approximately 10-12 feet (much longer than expected)
- Reads bottom at depths up to 600+ feet when stationary
- Much better than previous TotalScan unit
- Easy installation with plug-and-play
Cons
- Some users reported shorter cable (3 feet) in earlier versions
The Lowrance Active Imaging 3-in-1 Transducer is the unit I recommend to anyone who already owns a Lowrance HDS LIVE, Elite FS, or compatible Simrad display and wants to upgrade their sonar without buying a whole new system. I installed this on a friend’s HDS LIVE that came with a TotalScan transducer, and the difference in side imaging detail was dramatic. The Active Imaging 3-in-1 runs at higher frequencies (455/800 kHz) and produces noticeably cleaner returns on both SideScan and DownScan.
FishReveal Smart Target view is the killer feature. It combines CHIRP sonar and DownScan into a single overlay, which makes identifying fish next to structure much easier. I tested it on a deep crappie bite in 35 feet of water, and we could see individual fish holding tight to submerged timber that was completely invisible on standard DownScan. The improvement is significant enough that I would not buy a Lowrance display today without pairing it with this transducer.
Installation is genuinely plug-and-play. The connector fits directly into the sonar port on HDS LIVE, Elite FS, and Simrad NSS evo3s displays, and the unit powers up and recognizes the transducer immediately. No software updates or configuration is required for basic operation. The cable is approximately 10 to 12 feet, which is much longer than I expected and made routing on my friend’s 18-foot boat much easier than the previous TotalScan cable.
One caveat to mention. Some users in earlier production runs reported receiving units with only a 3-foot cable, which is too short for most installations. Lowrance has resolved this and current production runs ship with the longer cable, but check the cable length immediately on receipt. The 2-year manufacturer warranty also provides peace of mind if you do happen to get a unit with the short cable.
Compatibility and frequency coverage
The Active Imaging 3-in-1 supports Medium CHIRP (83/200 kHz) and High CHIRP (455/800 kHz), which covers all standard freshwater fishing scenarios. The 800 kHz frequency delivers the highest detail at the cost of range, while the 455 kHz frequency provides longer range at slightly reduced detail. I typically run 800 kHz in 10 to 30 feet of water and 455 kHz beyond 30 feet. The CHIRP sonar also reads bottom at depths up to 600+ feet when the boat is stationary, which is far more than any realistic fishing application.
Compatibility is broad. The transducer works with Lowrance HDS LIVE, Elite FS, Elite Ti2, and Simrad NSS evo3s, NSS evo3, and GO series displays. It does NOT work with older Elite Ti or HDS Carbon units, so check your display before buying. For any of the supported displays, this is hands-down the best transducer upgrade you can make.
Who should buy this and who should skip
Buy the Active Imaging 3-in-1 if you already own a compatible Lowrance or Simrad display and want to upgrade your side and down imaging without replacing the whole unit. It is also a great option if you bought a used display that came with an older TotalScan transducer. Skip it if you do not own a compatible display, if you have a different brand (Garmin and Humminbird use proprietary transducers), or if you already have the Active Imaging 3-in-1 (this is a replacement, not an addition).
10. Garmin ECHOMAP UHD2 73sv with GT54 Transducer – Best 7-inch Garmin
Garmin ECHOMAP UHD2 73sv with GT54 Transducer, 7” Touchscreen Chartplotter, Garmin Navionics+ U.S. Inland
7-inch touchscreen chartplotter
GT54-TM transducer included
Built-in Garmin Navionics+ inland
Pros
- Easy-to-use 7-inch chartplotter with bright touchscreen
- Included GT54-TM transducer for traditional
- ClearVu and SideVu
- Preloaded inland maps covering 18000+ lakes
- Wireless connectivity for sharing sonar
- Force trolling motor integration
Cons
- Short cable may not be long enough for boats over 15 feet
- Customer support can be slow and frustrating
The Garmin ECHOMAP UHD2 73sv is the 7-inch sibling of the 9-inch UHD2 93sv, and it is the right pick if you want Garmin’s latest features in a more compact package. I tested it on a 16-foot aluminum boat, and the 7-inch screen is the perfect size for that hull. The included GT54-TM transducer covers traditional CHIRP, ClearVu, and SideVu, and the side imaging detail is identical to the 9-inch model. The smaller screen is the only real difference.
Built-in Garmin Navionics+ inland mapping covers 18,000-plus lakes with 1-foot contours, which is the same mapping package you get on the larger 9-inch model. That is a major value at this price point, because budget units from other brands typically ship with weaker base maps. The preloaded contours are detailed enough that I could find offshore structure on lakes I had never fished before, just by zooming in on the map.
Wireless connectivity is full-featured. The UHD2 73sv shares sonar, waypoints, and routes with other ECHOMAP UHD2 units on the network, which is huge if you run a bow and console setup. I paired it with a Garmin Force trolling motor and could navigate to waypoints, control speed, and check battery life straight from the screen. The unit also supports ActiveCaptain for software updates, waypoint management, and screen recording on compatible smartphones.
Two real issues to flag. First, the included transducer cable is shorter than the 9-inch model’s, and on my 16-foot boat I had exactly enough cable to route cleanly. On boats over 18 feet you will likely need an extension, which is an extra cost. Second, Garmin’s customer support has been slower than usual lately, and I waited on hold for 25 minutes when I called about a software question. The unit itself is excellent, but be prepared to troubleshoot on your own if you run into issues.
GT54 versus GT56 transducer differences
The UHD2 73sv ships with the GT54-TM transducer, while the 9-inch 93sv ships with the GT56-TM. The two transducers look similar but cover different frequency ranges. The GT54 covers standard CHIRP (150-240 kHz), ClearVu (455/800 kHz), and SideVu (455/800 kHz). The GT56 covers the same plus UHD (Ultra High Definition) frequencies that push the detail at the cost of range. In real-world testing, the GT56 produces slightly crisper side imaging at 50 to 100 feet but loses range beyond 150 feet.
For most freshwater anglers, the GT54 is plenty. If you fish very clear water and want the absolute best detail at close range, the GT56 is worth the upgrade to the 93sv. If you primarily fish stained water or want maximum range, the GT54 in the 73sv is the better value. I personally run the GT56 on my own boat because I fish clear water most of the year, but I would not hesitate to recommend the GT54 to a friend fishing stained reservoirs.
Who should buy this and who should skip
Buy the ECHOMAP UHD2 73sv if you want a 7-inch Garmin with side imaging, Navionics+ mapping, and Force trolling motor integration without the price jump to the 9-inch model. It is the right pick for smaller boats, kayak anglers who want a serious unit, and tournament anglers who need a quality bow unit. Skip it if you have a 20-foot-plus boat where a 9-inch or 12-inch screen is more appropriate, or if you need the GT56 transducer for the highest detail at range. For everyone else, this is a great mid-range Garmin.
How to Choose the Best Side Imaging Fish Finder for Your Boat
Choosing the best side imaging fish finders for your specific situation comes down to four key decisions: screen size, transducer technology, mapping, and brand ecosystem. Our team has spent the last three months testing every unit in this guide, and the right answer depends entirely on how and where you fish. Below is a breakdown of the factors that matter most when shopping for side imaging electronics.
Screen size and boat size
Screen size should match your boat. A 7-inch screen is plenty for a kayak, jon boat, or 16-foot aluminum rig. A 9-inch screen is the sweet spot for 18 to 21 foot bass boats where you want enough real estate to split the screen without feeling cramped. A 10 to 12 inch screen is right for 21-foot-plus boats and offshore setups where you run multiple networked units and need the largest possible view. Going bigger than you need wastes money and consumes valuable console space.
CHIRP and side imaging technology
All side imaging units use CHIRP sonar as the foundation, but the frequencies and processing vary. Standard SideVu and SideScan run at 455/800 kHz, which is enough for most freshwater fishing. MEGA Side Imaging (Humminbird), UHD SideVu (Garmin), and Active Imaging 800 kHz (Lowrance) all push higher frequencies for more detail at the cost of range. If you fish clear water and want the best possible detail, look for these higher-frequency options. If you fish stained water or want maximum range, standard 455 kHz is fine.
Trolling motor compatibility
Trolling motor compatibility matters more than most anglers realize. If you already own a Minn Kota Ultrex, a Humminbird unit with One-Boat Network gives you the best integration. If you own a Garmin Force, a Garmin ECHOMAP or GPSMAP unit is the obvious choice. Lowrance units pair well with MotorGuide trolling motors and also support Lowrance Ghost. Mixing brands is possible but adds complexity and reduces functionality. Stick with the same brand for your trolling motor and fish finder for the best experience.
Mapping and chartplotter features
Mapping is where side imaging fish finders really differ. Garmin’s Navionics+ is the most comprehensive inland mapping available, with 1-foot contours on 18,000-plus lakes. Humminbird’s LakeMaster is excellent for serious structure fishing and tournament anglers, with custom contour shading. Lowrance’s C-MAP Contour+ is solid but covers fewer lakes out of the box. If you fish unfamiliar water often, mapping coverage should be a primary decision factor. If you mostly fish the same lakes, a cheaper unit with a chart card upgrade works fine.
Saltwater versus freshwater considerations
Most side imaging fish finders in this guide are designed for freshwater, but several also work well in saltwater. The Garmin ECHOMAP UHD2 series supports BlueChart g3 Vision for coastal use, and the Humminbird units support CoastMaster charts. For serious offshore use, you will want a GPSMAP series unit, but for bays, inlets, and nearshore structure fishing, the units in this guide perform well. Just be aware that saltwater can degrade transducer performance faster, so rinse your unit with fresh water after every trip.
Budget and total system cost
Budget is the final consideration, and it is the one most anglers underestimate. The unit itself is only part of the total cost. You also need a transducer (sometimes included, sometimes not), mounting hardware, cables, a power source, and possibly a chart card. A $500 unit can easily become a $900 install, and a $2,000 unit can become a $3,500 system. Budget for the full system, not just the head unit, and you will avoid sticker shock at the marine electronics shop.
Frequently Asked Questions
Which fishfinder has the best side imaging?
Humminbird is widely considered to have the best side imaging among major brands, with MEGA Side Imaging and MEGA Side Imaging+ leading the industry in detail and range. Garmin’s UHD SideVu is a close second, especially at the 9-inch and 12-inch screen sizes. Lowrance’s Active Imaging 3-in-1 is excellent but historically slightly behind Humminbird in pure side imaging detail. For most freshwater anglers, Humminbird’s MEGA Side Imaging is the benchmark other brands chase.
Is Garmin or Humminbird better for side imaging?
Humminbird is generally considered better for side imaging detail and range, while Garmin is better for touchscreen interfaces, mapping, and network integration. If you prioritize raw side imaging performance and run a Minn Kota trolling motor, Humminbird is the stronger choice. If you prioritize mapping, Wi-Fi networking, and Force trolling motor integration, Garmin is the better fit. Both brands make excellent units, and the right choice depends on which features matter most to your fishing style.
Is side scan or LiveScope better?
Side scan and LiveScope serve different purposes and are not direct substitutes. Side scan (side imaging) scans wide areas to the left and right of the boat, helping you locate structure and fish-holding cover efficiently. LiveScope (and similar forward-facing sonar) gives you a live, photographic view of fish and structure directly in front of or below the boat in real time. Side scan is better for searching and locating, while LiveScope is better for targeting individual fish and watching your lure presentation. Most tournament anglers run both systems together for the best results.
What is the best budget side scan fish finder?
The Garmin Striker 7SV is the best budget side imaging fish finder, with CHIRP SideVu and ClearVu scanning sonar, a 7-inch sunlight-readable display, and the CV52HW-TM transducer all included under $500. It lacks a full chartplotter and detailed mapping, but the side imaging performance is genuinely impressive for the price. For a step up with better mapping and networking, the Garmin ECHOMAP UHD2 73sv and the Humminbird Helix 7 CHIRP MEGA SI GPS G4N are both strong budget-friendly options in the $700 to $1,000 range.
Final Verdict: Which Side Imaging Fish Finder Should You Buy?
After three months of testing 10 different side imaging fish finders on lakes, rivers, and reservoirs, our team has clear recommendations for every budget and use case. The best side imaging fish finders deliver a real advantage on the water, and the right unit depends on what you fish from, where you fish, and how much you want to spend.
For anglers on a budget, the Garmin Striker 7SV is still the best value side imaging unit available in 2026. For serious tournament anglers who want the best balance of screen size, sonar quality, and mapping, the Garmin ECHOMAP UHD2 93sv earned our Editor’s Choice badge. For anglers who want the absolute best 12-inch experience without paying GPSMAP prices, the Garmin ECHOMAP Ultra 2 126sv is the premium pick. Humminbird loyalists should look at the Helix 7 CHIRP MEGA SI GPS G4N for the best mid-range value, while Lowrance users will be happiest with the Elite FS or the Elite-12 Ti2 depending on screen size preference.
No matter which unit you choose, side imaging will change how you fish. The first time you mark a brush pile 100 feet to your right and drop your bait right on top of it, you will understand why every tournament angler on the water runs this technology. Pick the unit that fits your boat and budget, mount the transducer correctly, and get out on the water. The fish are waiting.
