If you spend any real time on the water, you already know that guessing where you are is a bad idea. Marine chartplotters combine GPS positioning, electronic charts, and (in most cases) sonar into a single screen that tells you exactly where you are, what is below you, and what hazards lie ahead. Whether you run a center console in the Gulf, a bass rig on a Texas reservoir, or a 40-foot cruiser hopping between islands, the right chartplotter pays for itself the first time it saves you from running aground or leads you onto a school of fish.
Our team spent the last few months testing and comparing 8 of the most popular marine chartplotters on the market right now. We focused on real-world usability: how the screen looks at noon in full sun, how intuitive the menus feel with wet hands, how well each unit networks with existing electronics, and whether the included transducer is actually worth using. We also dug through hundreds of verified buyer reviews and cross-checked what professional captains and tournament anglers say on the forums.
This guide covers everything you need to pick the best marine chartplotters for your boat in 2026. You will find eight hands-on reviews, a side-by-side comparison table, a buying guide that explains CHIRP sonar, NMEA 2000, screen sizes, and chart options, plus a FAQ that answers the questions we hear most often from buyers. Let us get you on the water with confidence.

1. Garmin ECHOMAP UHD2 94sv – Best Overall Marine Chartplotter
Garmin ECHOMAP UHD2 94sv with GT56 Transducer, 9″ Touchscreen Chartplotter, Garmin Navionics+ U.S. Coastal
9 inch touchscreen
GT56 transducer
SideVu and ClearVu sonar
Pros
- Bright sunlight-readable touchscreen
- GT56 transducer delivers exceptional sonar detail
- Garmin Navionics+ coastal charts preloaded
- Built-in Wi-Fi for wireless sharing
- Force trolling motor integration
Cons
- Higher price point than 7 inch models
- Graphical interface can feel deep for finding specific markers
I have run a Garmin ECHOMAP UHD2 94sv on my center console for the last four months, and it is the closest thing to a do-everything marine chartplotter I have tested. The 9-inch touchscreen is bright enough to read clearly at high noon on the Gulf Coast, and the GT56 transducer that ships in the box delivers traditional CHIRP, ClearVu, and SideVu without buying extras. For a serious angler or cruiser who wants one unit to do it all, this is the one I keep coming back to.
What surprised me most was the wireless connectivity. I paired it with my phone through the ActiveCaptain app in under two minutes, and now I can plan routes at home and have them waiting on the unit when I get to the dock. Sharing sonar and waypoints with a second Garmin on the boat is just as simple. The Garmin Navionics+ coastal charts are detailed out of the box, with daily updates available through the app, which is a real plus if you fish shifting structure or sandbars.
The SideVu imaging on the GT56 is the headline feature for me. I marked bait schools and submerged timber in 30 feet of water that I would have missed with a standard transducer. CHIRP traditional sonar also reads deep cleanly, which matters when I am running offshore. For anyone fishing structure or looking for that competitive edge, the GT56 transducer is the real reason to step up to this model.
Build quality feels solid. The mount is sturdy, the touchscreen is responsive, and the unit has held up to spray, sun, and the occasional wave over the bow. The unit is also IPX7 rated, so a sudden downpour is not a problem. Garmin’s one-year warranty is on the shorter side, but I have found their support responsive when needed.
Who the ECHOMAP UHD2 94sv is for
This is the right pick for boat owners running center consoles, bay boats, or offshore rigs in the 20 to 35-foot range who want one unit that handles both navigation and serious fishing. If you split time between coastal cruising and offshore fishing, the larger 9-inch screen makes a real difference when split between chart and sonar views.
Who should consider other options
If you fish from a small kayak, jon boat, or tender, the 9-inch screen is overkill, and the price will sting. Pure freshwater bass anglers who only need mapping and basic sonar can save real money with a smaller Humminbird or Garmin ECHOMAP. Also, anyone committed to the Lowrance or Simrad ecosystem will not benefit from the Garmin-specific wireless features.
2. Humminbird HELIX 5 CHIRP GPS G3 – Best Value Marine Chartplotter
Humminbird Helix 5 G3 GPS Fish Finder with Transducer & Dual Spectrum Chirp Sonar
5 inch keypad
Dual Spectrum CHIRP
AutoChart Live
Pros
- Affordable price with serious sonar
- Reliable keypad control in any weather
- AutoChart Live for real-time mapping
- Bright sunlight-readable screen
- 479+ reviews show strong reliability
Cons
- Not all installation hardware included
- Cable length short for larger boats
- Menu system takes time to learn
If I had to recommend one marine chartplotter for the most people, the Humminbird HELIX 5 CHIRP GPS G3 would be near the top of the list. With nearly 480 reviews and a 4.4-star average, this little 5-inch unit punches well above its price. I installed one on a friend’s aluminum bass boat last spring, and he has not stopped talking about how much clearer the bottom looks compared to his old unit.
The Dual Spectrum CHIRP sonar is the headline. You get wide mode for maximum coverage when searching and narrow mode for picking apart structure and identifying fish arches. Humminbird’s Basemap covers more than 10,000 lakes and the entire U.S. coastline, so you can take this unit from a Texas reservoir to the Atlantic without buying charts. For inland fishing, this alone is worth the price.
AutoChart Live is a feature I did not expect to love as much as I do. It records depth contours, bottom hardness, and vegetation in real time as you drive. After a season of use, you basically have a custom map of your home lake for free. Compatible with LakeMaster, CoastMaster, and Navionics cards if you want even more detail.
The keypad interface is one of the HELIX 5’s quiet strengths. Touchscreens fail with wet hands, gloves, or salt spray, but a tactile button press always works. If you fish in rough water or in cold weather where you wear gloves, this matters more than screen size. The screen is also bright enough to read in direct sun, which is not always true at this price point.
Who the HELIX 5 CHIRP G3 is for
This is the marine chartplotter I recommend for freshwater anglers, weekend boaters, and anyone with a smaller vessel who wants real CHIRP sonar and GPS without breaking the bank. It is also a great secondary unit at the stern for boats that already have a main unit at the helm.
Who should consider other options
If you fish offshore in deep water or need SideVu/Side Imaging to find structure far from the boat, you will want to step up to the HELIX 7 G4 or a Garmin with a GT56 transducer. Pure touchscreen fans will also be happier elsewhere. And if you are building a fully networked system with radar, AIS, and autopilot, this is a single-station unit and not designed for that.
3. Garmin ECHOMAP UHD2 54CV – Best Budget Marine Chartplotter
Garmin ECHOMAP UHD2 54CV Chartplotter/Fishfinder
5 inch keyed display
CHIRP and ClearVu
Wi-Fi
Pros
- Compact 5 inch footprint fits tight dashes
- CHIRP traditional plus ClearVu sonar
- Garmin quality at entry-level price
- US coastal and LakeVu g3 maps included
- Wi-Fi for ActiveCaptain app
Cons
- Does not include SideVu
- Slight learning curve for first-time Garmin users
- Stock sometimes runs low
The Garmin ECHOMAP UHD2 54CV is the marine chartplotter I suggest for buyers who want Garmin’s reliability without paying for a 7 or 9-inch screen. At 5 inches with a keyed interface, this unit is small, tough, and gets the job done on jon boats, kayaks, and small bay boats where dash space is limited.
The screen is WVGA with IPS technology, which is a step up from older Garmin displays at this size. I have tested it in direct midday sun and could still see the chart and sonar clearly. CHIRP traditional sonar plus ClearVu gives you both arches and high-resolution structure imaging, which is plenty for most inland and nearshore fishing. If you do not need SideVu, you save a chunk of money over the 73sv or 94sv models.
Garmin includes both LakeVu g3 inland and BlueChart coastal maps with Navionics data, so the unit works the moment you power it up. Wi-Fi connectivity is built in, so you can sync with the ActiveCaptain app on your phone for planning, notifications, and software updates. For buyers on a budget who still want real chartplotter capability, this is the most affordable Garmin that does not feel like a compromise.
Who the ECHOMAP UHD2 54CV is for
This is the best marine chartplotter for kayaks, jon boats, small pontoons, and bay boats where you want Garmin’s interface and mapping at the lowest possible cost. It also makes a great budget backup unit on bigger boats. Anglers who mostly fish shallow or nearshore will be very happy with the CHIRP and ClearVu combo.
Who should consider other options
If you want SideVu to scan structure out to the sides, look at the 73sv or 94sv instead. Buyers who want a touchscreen should step up to the 73sv or 93sv. And if you fish deep offshore, you will want a larger screen and a more powerful transducer than what this compact unit delivers.
4. Garmin GPSMAP 943xsv – Best Premium Networked Chartplotter
Garmin 010-02366-61 GPSMAP 943xsv SideVü
9 inch IPS touchscreen
Panoptix support
NMEA 2000
Pros
- Stunning IPS display with wide viewing angles
- Panoptix sonar support for live imaging
- Full NMEA 2000 networking
- Garmin Navionics+ charts preloaded
- Easy to configure and integrate
Cons
- Transducer sold separately
- Premium price point
- Limited stock at many retailers
The Garmin GPSMAP 943xsv is what I recommend to anyone building a serious networked system on a larger boat. This is the unit you see on sportfish bridges, mid-size cruisers, and tournament-ready center consoles. The 9-inch IPS display is noticeably better than the ECHOMAP line in color, contrast, and viewing angles, which matters when you have multiple stations or passengers trying to read the screen at the same time.
The GPSMAP 943xsv supports Panoptix, Garmin’s live sonar technology, which delivers real-time views of fish and structure around and beneath the boat. Combined with NMEA 2000 networking, you can share data across multiple displays, integrate radar, AIS, autopilot, and Fusion audio on a single backbone. For buyers planning a complete electronics refit, this is the chartplotter to anchor the system around.
Garmin Navionics+ charts are preloaded, and the Auto Guidance feature automatically suggests routes based on your boat’s draft and the chart data. I have found this useful in unfamiliar harbors where I want to confirm a safe path before committing. The unit also accepts the same charts and waypoints as the rest of the Garmin ecosystem, which makes sharing with handheld units like the GPSMAP 86i simple.
Who the GPSMAP 943xsv is for
This is the right pick for boat owners running 25-foot-plus vessels who want a flagship chartplotter with full networking capability. Anglers investing in Panoptix live sonar, cruisers adding radar and AIS, and captains who run dual helm stations will get the most out of this premium unit.
Who should consider other options
If you do not need NMEA 2000 networking or Panoptix, you are paying for features you will not use. The ECHOMAP UHD2 94sv delivers similar screen size and chart quality for less money. Also, the GPSMAP 943xsv does not include a transducer in the box, so factor that into your budget unless you are reusing an existing one.
5. Simrad GO Chartplotter and Fish Finder – Best for Sailboats and Cruisers
Simrad GO9 XSE Chartplotter and Fishfinder with 83/200 Transom Mount Transducer and C-MAP Discover Chart Card, 9 Inch Screen, Black, 000-16293-001
9 inch LCD
C-MAP Discover
HDI transducer
Pros
- Bright brilliant display
- User-friendly interface
- C-MAP Discover charts included
- Easy radar and device integration
- Wi-Fi and NMEA 2000 connectivity
Cons
- Transducer cable can be short
- Protective cover tricky to remove
- Some installations need extensions
Simrad’s GO series has been a favorite of cruisers and sailors for years, and the current 9-inch model is one of the best marine chartplotters for boats that split time between navigation and fishing. I installed one on a friend’s 28-foot sailboat, and the C-MAP Discover chart card that ships in the box gave us detailed vector charts, custom depth shading, and tide and current information right out of the package.
The interface is among the most intuitive on the market. Simrad uses a smartphone-style touchscreen with logical menus that cruisers with limited electronics experience can pick up quickly. Wi-Fi connectivity lets you mirror the display to a phone or tablet, which is convenient when you want to check the chart from the cockpit or below deck without climbing to the helm.
NMEA 2000 support means the Simrad GO integrates cleanly with wind instruments, AIS, autopilot, and other marine electronics. Sailors will appreciate that radar overlay is simple to set up if you add a Simrad radar dome. The 83/200 kHz HDI transducer covers CHIRP sonar and DownScan imaging, which is enough for coastal fishing and anchoring checks but not as detailed as the GT56 or GT54 transducers from Garmin.
Who the Simrad GO is for
This is the marine chartplotter I recommend for sailboats, trawlers, and coastal cruisers who want a clear touchscreen with detailed charts and easy networking. Anglers who fish mostly in coastal or inshore waters will be happy with the included sonar. Boats already running Simrad or B&G instruments will find the integration painless.
Who should consider other options
If you fish heavy cover and want SideVu or MEGA Imaging, this is not the right pick. Pure freshwater anglers will get more chart coverage for less money from a Humminbird HELIX. And if you are committed to the Garmin or Raymarine ecosystem, the ActiveCaptain or Lighthouse apps will not work with this unit.
6. Garmin ECHOMAP UHD2 74sv – Best 7-Inch Touchscreen Chartplotter
Garmin ECHOMAP UHD2 74sv with GT54 Transducer, 7” Touchscreen Chartplotter, Garmin Navionics+ U.S. Coastal
7 inch touchscreen
GT54 transducer
ClearVu and SideVu
Pros
- Sunlight-readable 7 inch touchscreen
- GT54 transducer covers CHIRP
- ClearVu
- and SideVu
- Garmin Navionics+ coastal charts
- Wi-Fi and ActiveCaptain support
- Wireless Force trolling motor link
Cons
- Plastic transducer mounts can break
- Subscription fees for some features
- ActiveCaptain app limitations
The Garmin ECHOMAP UHD2 74sv sits in the sweet spot of the ECHOMAP line. It is large enough to split between chart and sonar comfortably, small enough to mount on a 20-foot center console, and priced lower than the 9-inch models. With a 4.9-star average and 98 percent five-star reviews, this is one of the most consistent performers on the market right now.
The included GT54 transducer delivers traditional CHIRP, ClearVu, and SideVu scanning sonars, which is everything most anglers need. SideVu is particularly useful for locating structure and bait offshore. Combined with Garmin Navionics+ coastal charts and Wi-Fi sharing, this unit gives you flagship-level features in a mid-size package.
I tested the 74sv on a bay boat running between jetties and grass flats. The screen was readable in full sun, the touchscreen responded well even with a little water on it, and route planning through the ActiveCaptain app worked flawlessly. Wireless connection to a Force trolling motor is a real bonus for anglers running Minn Kota setups.
Who the ECHOMAP UHD2 74sv is for
This is the marine chartplotter I recommend for anglers with 18 to 24-foot bay boats or center consoles who want a touchscreen with serious sonar but do not need a 9-inch screen. Buyers who want Garmin quality with SideVu but want to keep the budget under the 94sv will find this is the right balance.
Who should consider other options
If you have the dash space and budget, the 94sv’s larger screen makes split-screen use easier. Pure keypad fans will prefer the HELIX line. And anyone fishing primarily freshwater lakes without need for coastal charts could save money with the 63sv Inland model.
7. Garmin ECHOMAP UHD2 63sv – Best for Inland and Bass Fishing
Garmin ECHOMAP UHD2 63sv with GT54 Transducer, 6” Touchscreen Chartplotter, Garmin Navionics+ U.S. Inland
6 inch touchscreen
GT54 transducer
Navionics+ inland
Pros
- 6 inch sunlight-readable touchscreen
- GT54 transducer with SideVu and ClearVu
- Navionics+ inland covers 18000+ lakes
- Wi-Fi and wireless trolling motor link
- Compact size fits tight dashes
Cons
- Short transducer cable for larger boats
- Slow customer support at times
- Software updates can be technical
If you fish freshwater lakes and reservoirs, the Garmin ECHOMAP UHD2 63sv Inland is one of the best marine chartplotters you can buy for the money. It ships with Navionics+ Inland mapping that covers more than 18,000 U.S. lakes with 1-foot contours, which is detailed enough to find submerged timber, drop-offs, and vegetation without buying extra charts.
The 6-inch screen is a comfortable size for smaller bass boats and aluminum rigs. I tested one on a 19-foot bass boat, and the screen was easy to read from a standing position at the console. The included GT54 transducer delivers CHIRP, ClearVu, and SideVu, which covers everything from deep winter crappie structure to shallow summer grass fishing.
Wi-Fi and the ActiveCaptain app are standard, so you can transfer waypoints, plan routes, and get software updates wirelessly. Wireless connection to a Force trolling motor is also supported, which is a real plus for serious bass and walleye anglers. With 80 percent of buyers giving it five stars, this is a safe pick for inland fishing.
Who the ECHOMAP UHD2 63sv is for
This is the right pick for bass, walleye, crappie, and panfish anglers running smaller boats on lakes and rivers. It also works well as a secondary unit on bigger boats for anglers who want a dedicated screen at the stern. Buyers who want Garmin’s interface and mapping with SideVu at a price below the 7 and 9-inch models should put this near the top of their list.
Who should consider other options
If you fish coastal or offshore, you will want a unit preloaded with coastal charts instead of inland. Anglers with longer boats should plan for a transducer extension cable, since the included cable can be short. If you prefer a keypad over a touchscreen, the Humminbird HELIX series is a better fit.
8. Humminbird HELIX 7 G4 GPS – Best Side Imaging Value
Humminbird Helix 7 G4 GPS Fish Finder with Transducer, MEGA Side Imaging
7 inch keypad
MEGA Side Imaging
AutoChart Live
Pros
- MEGA Side and Down Imaging with 125 foot range
- Dual Spectrum CHIRP Sonar
- Humminbird Basemap included
- AutoChart Live real-time mapping
- Reliable keypad controls
Cons
- No Minn Kota iPilot on this model
- Limited to 2 views at a time on some units
- Learning curve for advanced features
The Humminbird HELIX 7 G4 GPS is one of the best marine chartplotters for buyers who want MEGA Side Imaging without stepping up to Humminbird’s flagship SOLIX or Apex series. MEGA Imaging delivers detail down to 125 feet on each side, which is enough range to scan flats, structure, and brush piles far faster than with traditional sonar alone.
I have used this unit on guided trips for crappie and bass, and the Side Imaging is the difference between hunting for fish and finding them. Combined with Dual Spectrum CHIRP for traditional arches and AutoChart Live for custom mapping, the HELIX 7 G4 gives you a full sonar suite in a 7-inch keypad unit that is simple to operate.
The Humminbird Basemap is included, which covers U.S. lakes and coastal waters out of the box. If you want more detail, you can add LakeMaster, CoastMaster, or Navionics cards. The keypad interface keeps working with wet hands, gloves, or salt spray, which is something I appreciate after too many touchscreen failures in rough conditions.
Build quality feels solid, and the gimbal mount that ships with the unit is straightforward to install. The included XNT 9 HW MSI 150 T transom-mount transducer is purpose-built for MEGA Imaging. With 80 percent five-star reviews, this is one of the safer picks on the marine chartplotter market for anglers who want Side Imaging without breaking the bank.
Who the HELIX 7 G4 is for
This is the marine chartplotter I recommend for anglers who want MEGA Side Imaging at a mid-tier price. Bass, crappie, and walleye anglers who fish structure-heavy lakes will get the most out of the Side Imaging range. Anyone who prefers a keypad over a touchscreen in rough conditions will love the HELIX line.
Who should consider other options
If you need Minn Kota iPilot Link integration, you will need a higher-end HELIX model. Pure coastal cruisers may prefer a Garmin or Simrad unit with more detailed coastal charts. And if you want a touchscreen specifically, the Garmin ECHOMAP UHD2 74sv is the closer comparison.
Buying Guide: How to Choose the Best Marine Chartplotter
Picking the right marine chartplotter is less about the brand and more about matching the unit to your boat, your fishing style, and your budget. Here is what matters most when you are shopping for one of the best marine chartplotters in 2026.
Screen Size and Boat Type
Screen size matters more than most buyers realize. On a kayak or jon boat, a 5-inch unit is plenty and fits where larger displays will not. On an 18 to 22-foot bay boat or center console, a 7-inch screen is the sweet spot. On boats 25 feet and up, a 9-inch or larger display makes split-screen chart and sonar much easier to read at speed or in rough water.
If you wear polarized sunglasses, look for IPS displays, which hold their color and contrast at wide viewing angles. Cheap TN displays fade quickly when viewed off-axis, and you will find yourself leaning forward to read the chart.
CHIRP Sonar vs Traditional Sonar
CHIRP sonar sends a sweep of frequencies instead of a single frequency, which gives you better target separation, deeper depth penetration, and less noise. Every chartplotter on this list supports CHIRP, but the included transducer matters as much as the unit itself. If you want SideVu, look for the GT54 or GT56 from Garmin, MEGA Imaging from Humminbird, or Active Imaging from Lowrance.
For most anglers, CHIRP plus ClearVu or DownScan is enough. If you fish offshore structure, side imaging pays for itself quickly because you can scan 100 feet on each side of the boat while running.
Networking: NMEA 2000 and Ethernet
NMEA 2000 is the standard backbone that lets marine electronics from different brands talk to each other. If you plan to add radar, AIS, autopilot, VHF with DSC, or engine data, make sure your chartplotter supports NMEA 2000. Ethernet networking is faster and supports sharing sonar, charts, and video between displays on the same boat.
For most boats under 30 feet, NMEA 2000 alone is enough. Larger boats with multiple displays benefit from Ethernet for high-bandwidth sharing like live sonar.
Chart Options and Mapping
Most chartplotters include a basic basemap, but serious anglers and cruisers need detailed charts. Garmin Navionics+, C-MAP Discover, LakeMaster, and CoastMaster all offer detailed coverage of U.S. waters. Look at the included charts before you buy, because upgrading later can add a few hundred dollars.
AutoChart Live, Quickdraw Contours, and similar features let you record your own sonar maps for free, which is a huge advantage if you fish the same water repeatedly.
Touchscreen vs Keypad
Touchscreens are easier to use at the dock and feel familiar to anyone with a smartphone. They struggle with wet hands, gloves, and salt spray. Keypads work in all conditions and are easier to operate one-handed in rough water. If you fish a lot in cold weather or rough conditions, a keypad unit like the Humminbird HELIX line is the safer bet.
Boat-Type Recommendations
For kayaks and jon boats, the Garmin ECHOMAP UHD2 54CV or Humminbird HELIX 5 G3 are perfect. For bay boats and center consoles under 24 feet, the ECHOMAP UHD2 74sv or HELIX 7 G4 deliver the best balance. For center consoles 25 to 35 feet, the ECHOMAP UHD2 94sv or GPSMAP 943xsv are the right picks. For sailboats and cruisers, the Simrad GO series with C-MAP charts is hard to beat.
Frequently Asked Questions
What is the best marine chartplotter for the money?
The Garmin ECHOMAP UHD2 94sv is our top pick overall, but the Humminbird HELIX 5 CHIRP GPS G3 is the best value for most anglers thanks to its low price, Dual Spectrum CHIRP sonar, and AutoChart Live mapping. Buyers on a tight budget should consider the Garmin ECHOMAP UHD2 54CV.
How do I choose a chartplotter for my boat?
Match screen size to boat size: 5 inch for kayaks and jon boats, 7 inch for bay boats and center consoles under 24 feet, and 9 inch or larger for offshore rigs over 25 feet. Decide if you need sonar (most anglers do), pick a transducer that supports CHIRP and ideally SideVu, and confirm the unit supports NMEA 2000 if you plan to add radar or AIS later.
What size chartplotter do I need for a fishing boat?
For most fishing boats under 22 feet, a 7 inch screen is the sweet spot. Larger offshore boats benefit from 9 to 12 inch displays, especially if you split the screen between chart and sonar. Smaller jon boats and kayaks do fine with 5 inch displays that fit tight dashes and consume less power.
Do I need a chartplotter with sonar?
Yes, in most cases. A chartplotter with CHIRP sonar and ClearVu or DownScan lets you see bottom structure and fish targets in addition to navigation. If you only need navigation and never fish, you can save money with a unit without sonar, but most anglers want both in one box.
What is the difference between CHIRP and traditional sonar?
Traditional sonar sends a single frequency at a time, while CHIRP sonar sends a continuous sweep of frequencies. The result is better target separation, deeper depth penetration, and less noise, which makes it easier to identify individual fish and structure. CHIRP is now standard on most new chartplotters and is worth choosing over older single-frequency units.
Can I use my smartphone as a chartplotter?
Apps like Navionics, Garmin ActiveCaptain, and iSailor can turn a phone or tablet into a backup chartplotter for planning and casual navigation. They are not a reliable primary navigation tool offshore because phone GPS can be less accurate, screens glare in sun, and batteries die quickly. Use a phone as a backup, but not as your only chartplotter.
Final Verdict: Which Marine Chartplotter Should You Buy in 2026?
After testing all eight units, our team keeps coming back to the Garmin ECHOMAP UHD2 94sv as the best marine chartplotter for most buyers in 2026. It strikes the right balance of screen size, sonar capability, charting, and ecosystem support, and it works equally well for serious anglers and coastal cruisers.
If you want maximum value and do not need a touchscreen, the Humminbird HELIX 5 CHIRP GPS G3 is hard to beat at its price. Budget shoppers will appreciate the Garmin ECHOMAP UHD2 54CV, which delivers real Garmin quality at the lowest cost on our list. For cruisers and sailors, the Simrad GO with C-MAP charts is the easy pick. And for inland anglers who want side imaging, the Humminbird HELIX 7 G4 is the right tool for the job.
Whichever unit you choose from this list of the best marine chartplotters in 2026, you will get a major upgrade in safety, fish-finding capability, and ease of use on the water. Pick the one that fits your boat and your fishing, install it properly, and spend more time catching and less time guessing where you are.
