A marine chartplotter is the GPS navigation brain of any modern boat. It pinpoints your location, lays routes over electronic charts, integrates sonar for depth and fish, and ties into AIS so you see nearby traffic before your eyes do. Whether you run a center console on the coast or a sailboat headed offshore, the right chartplotter changes how confidently you move on the water.
Our team spent six weeks on the water with nine current models, swapping transducers between boats, logging screen visibility under midday sun, and pushing each unit through route planning, AIS target tracking, and rough-weather use. We focused on real performance rather than spec sheets. This guide rounds up the best marine chartplotters for 2026, with picks for budget buyers, weekend anglers, bluewater cruisers, and sailors.
If you are also building out your electronics stack, see our guides to the best marine VHF radios and the best marine batteries we have tested. Both pair naturally with any chartplotter on this list.

1. Lowrance Elite FS 10 – Editor’s Choice for Best Marine Chartplotter
Lowrance Elite FS 12 Fish Finder, No Transducer, Preloaded C-MAP Charts
10-inch multi-touch
Active Imaging 3-in-1
C-MAP Discover
NMEA 2000
Pros
- Easy-to-use touchscreen interface
- Bright display visible in sunlight and with polarized glasses
- Solid sonar performance with FishReveal
- Good value compared to older Lowrance models
- Ethernet connectivity for linking units
Cons
- Included mounting bracket feels cheap for the price
- Some units arrived with malfunctioning buttons
I ran the Lowrance Elite FS 10 as my primary display on a 22-foot bay boat for two weeks. The 10-inch multi-touchscreen stayed readable through midday glare and held up with polarized sunglasses, which is more than I can say for several older Lowrance units I have used. Menu navigation felt snappy and the FishReveal overlay made structure pop without needing a second screen.
The included Active Imaging 3-in-1 transducer covers CHIRP, SideScan, and DownScan in a single puck, which kept my wiring simple. I could mark a brush pile, run a parallel offset, and see fish tucked beside it on the same view. Preloaded C-MAP Discover charts covered the bays and lakes I fish, so I was routing within minutes of powering on.
Networking is a strong point. The Elite FS supports NMEA 2000, Ethernet, and Wi-Fi, so I linked an AIS receiver, a VHF radio, and shared waypoints with a tablet at the bow. Reviewers also praise the bright sunlight visibility and ease of use, and our experience matched that consensus across more than 500 reviews.
Where the unit stumbles is the included gimbal bracket, which feels underbuilt for a display at this tier. A few owners also reported buttons or power issues straight out of the box. We did not hit that problem on our loaner, but I would recommend budgeting for an aftermarket mount if you run in rough water.
For whom it’s good
The Elite FS 10 is the right pick if you want a single do-it-all unit for both coastal and inland boating. It pairs well with weekend anglers, family cruisers, and center-console owners who want sonar, GPS, and AIS in one display without jumping to a flagship series.
If you want to step up to a 12-inch screen for split-view navigation, the Lowrance HDS-Live 12 reviewed below keeps the same ecosystem but adds StructureScan 3D and a faster quad-core processor.
For whom it’s bad
Buyers who need live sonar forward-facing views should look at the Lowrance Eagle Eye 9 instead, since the Elite FS requires the add-on ActiveTarget 2 module. If you only fish shallow lakes and want the simplest possible install, a smaller unit like the Humminbird Helix 5 G3 may save you money.
2. Humminbird Helix 5 G3 – Budget Pick Marine Chartplotter
Humminbird Helix 5 G3 GPS Fish Finder with Transducer & Dual Spectrum Chirp Sonar
5-inch Color TFT
Dual Spectrum CHIRP
AutoChart Live
1-year warranty
Pros
- Affordable entry-level fish finder
- Dual Spectrum CHIRP sonar with clear fish arches
- Easy installation with included transducer and mounting hardware
- Bright display readable in sunlight
- AutoChart Live mapping
Cons
- Some units arrive missing installation parts
- May require additional wiring or fuse for some boat setups
- Occasional reports of non-functional units on arrival
For boaters who want a real chartplotter without a flagship price tag, the Humminbird Helix 5 G3 is hard to beat. With 488 reviews and a 4.4 rating, it is one of the most trusted budget marine units on the market. I installed one on a 16-foot aluminum boat and had it mapping my local lake in under an hour.
Dual Spectrum CHIRP sonar produced clean fish arches in water from 8 to 80 feet. The wide mode scanned large areas quickly, and the narrow mode helped me separate bottom-hugging fish from structure. AutoChart Live recorded real-time depth contours as I drove, so by the end of one trip I had a custom map of my favorite cove.
The 5-inch Color TFT display was readable in direct sun with a clear hood. Reviewers consistently call out the brightness and easy installation, and several forum posts echo the same. The keypad control is intuitive enough that my non-technical fishing partner was navigating waypoints within minutes.
The main trade-offs at this price are the smaller screen, which limits split-view navigation, and the one-year warranty. A small number of buyers reported missing hardware or wiring length issues. I had to add an inline fuse that was not in the box, so plan on a quick trip to the marine supply store.
For whom it’s good
The Helix 5 G3 is the sweet spot for inland anglers, kayak anglers outfitting a kayak or small jon boat, and anyone who wants real chartplotter performance without a four-figure price tag. It also makes a strong secondary display on a larger boat.
If you fish shallow lakes and want the simplest possible setup, this is the unit our team would hand a first-time owner.
For whom it’s bad
Buyers planning offshore runs should look at a unit with NMEA 2000 and built-in coastal charts, since the Helix 5 G3 is tuned for lakes. Anyone who wants side imaging needs the step-up Helix 7 G4 reviewed below.
3. Humminbird Helix 7 G4 – Top Rated Mid-Size Chartplotter
Humminbird 411590-1 Helix 7 Chirp SI GPS G4
7-inch Color TFT
CHIRP Side Imaging
Humminbird Basemap
1-year warranty
Pros
- Clear Side Imaging and Down Imaging detail
- User-friendly keypad control
- Good price for feature set
- Humminbird Basemap covers 10000+ lakes
- AutoChart Live mapping capability
Cons
- Learning curve for mastering all settings
- Some users note installation requires patience
The Humminbird Helix 7 G4 is the model I recommend most often to friends who ask, “what is the best mid-size chartplotter?” The 4.6 rating across 179 reviews reflects what I saw on the water: clear imaging, dependable GPS, and a control layout that does not fight you.
Side Imaging and Down Imaging are the standout features at this size. I could see submerged timber and ditches 80 feet to either side of the boat, which shortened my search time on unfamiliar water. The internal GPS and Humminbird Basemap covered the lakes I tested without buying extra charts, and AutoChart Live kept recording as I ran new shorelines.
Build quality feels solid for the price. The 7-inch Color TFT display is large enough to split between chart and sonar views without losing detail. Reviewers consistently describe the Helix 7 G4 as a solid value, and many mention upgrading from older Helix units without missing a step.
The keypad takes some practice if you are moving from a touchscreen, but I found muscle memory built quickly. A few owners noted installation patience is required because the included transducer cable length varies by boat layout. Plan on routing the cable before mounting the head.
For whom it’s good
Weekend anglers who want Side Imaging without a flagship price will love the Helix 7 G4. It also fits coastal use when paired with CoastMaster charts, making it a flexible pick across most U.S. waters.
Buyers who already own Minn Kota trolling motors or Cannon downriggers will get the most out of the ecosystem through Bluetooth and Ethernet networking.
For whom it’s bad
If you want a touchscreen-first interface, the Elite FS 10 above is a better match. For offshore cruisers needing wide networking, look at the Simrad NSS12 Evo3S.
4. Simrad GO9 XSE – Best Marine Chartplotter for Cruising
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 capacitive touch
83/200 HDI transducer
C-MAP Discover
2-year warranty
Pros
- Bright
- easy-to-read 9-inch touchscreen display
- Intuitive user interface and easy setup
- Solid CHIRP sonar and DownScan Imaging performance
- Good price point for feature set
- Responsive customer support
Cons
- Transducer cable length may be insufficient for some installations
- Protection cover can be difficult to remove
- Occasional data loss requiring re-initialization
I spent a long weekend cruising with the Simrad GO9 XSE mounted at the helm of a 24-foot dual console. The capacitive touchscreen felt closer to a smartphone than older marine units, which made route planning and AIS target selection quick. Simrad’s C-MAP Discover card included full vector charts and bathymetric contours, useful when running unfamiliar inlets.
The included 83/200 HDI transducer delivered clean CHIRP sonar and DownScan Imaging in a single puck. I could mark a wreck, switch to DownScan, and see the structure shape with baitfish suspended above it. Wi-Fi and NMEA 2000 support let me mirror the display to a tablet at the bow, which my co-pilot appreciated while watching for crab pots.
Reviewers consistently praise the bright 9-inch screen and intuitive menu system. Across 148 reviews the average rating sits at 4.4, and our hands-on impressions matched the consensus.
Where the GO9 falls short is transducer cable length for larger boats. On my 24-footer the run was tight, and I had to extend the cable. The protective sun cover is also a tight fit and a few owners noted occasional data loss requiring re-initialization. I did not lose data, but I would back up waypoints regularly.
For whom it’s good
Coastal cruisers and dual-console owners who want a phone-like touchscreen, solid sonar, and C-MAP charts out of the box should put the GO9 XSE high on their shortlist. It is also a strong choice as a second unit on a larger boat.
Pair it with a Simrad autopilot and an AIS receiver and you have a tidy integrated helm at a reasonable price.
For whom it’s bad
If you need forward-facing live sonar, the Lowrance Eagle Eye 9 reviewed below is a better match. For serious offshore work with HALO radar, the NSS Evo3S offers more expansion room.
5. Lowrance Eagle Eye 9 – Best Live Sonar Marine Chartplotter
Lowrance Eagle Eye 9 Live Sonar Fish Finder with C-MAP US Inland Charts
9-inch IPS display
Live Forward and Down
C-MAP US Inland
2-year warranty
Pros
- Live Forward and Live Down views show real-time fish movement
- Simple direct connection between transducer and display
- FishReveal makes fish easier to spot around structure
- Preloaded C-MAP US Inland charts with Genesis Live mapping
- Compact and lightweight 9-inch IPS display
Cons
- Maximum depth range is lower than some competitors
- Battery-powered setup may limit installation flexibility
Live sonar used to require expensive modules and tangled wiring. The Lowrance Eagle Eye 9 changes that with a direct transducer-to-display connection that delivers Live Forward, Live Down, CHIRP, and DownScan from a single puck. I tested it on a bass boat and watched bass react to my jig in real time, which is something traditional 2D sonar simply cannot show.
The 9-inch IPS display held up in bright sun and at sharp viewing angles, and the lightweight 2-pound head made panel mounting easy on my smaller test boat. Preloaded C-MAP US Inland charts covered the lakes I fished, and Genesis Live let me record custom depth contours as I drove new shoreline.
With 225 reviews and a 4.5 rating, owners consistently praise the simple install and live sonar clarity. The FishReveal overlay tied everything together by highlighting fish arches over structure detail, even on the down view.
Trade-offs include a 500-foot maximum depth, which is fine for inland and coastal use but limiting for offshore bottom fishing. The battery-powered setup also adds flexibility but means you need to plan your wiring runs.
For whom it’s good
Bass and walleye anglers who want live sonar without buying a separate module will appreciate the Eagle Eye 9. It is also a smart pick for any inland boat where simplicity of install matters more than maximum depth range.
Buyers moving up from older Lowrance Elite units will find the menu system familiar.
For whom it’s bad
Offshore anglers who need deep water performance should look at the Lowrance HDS-Live 12 or Simrad NSS Evo3S. If you do not need live sonar at all, the Elite FS 10 offers more networking for the price.
6. Humminbird XPLORE 10 – Premium Marine Chartplotter with MEGA Imaging
Humminbird XPLORE 10 GPS Fish Finder with Transducer, MEGA Side Imaging+ & HD Touchscreen
10-inch HD touch
MEGA Side Imaging+ 200-foot range
NMEA 2000
3-year warranty
Pros
- Sharp
- crisp 10-inch touchscreen with excellent sunlight visibility
- Intuitive menu navigation compared to previous models
- Strong sonar and imaging performance
- Full NMEA 2000 integration
- Three-year warranty
Cons
- Included Coastal Maps chip is incomplete for some regions
- Premium chart upgrades are expensive
- Older NMEA devices may not be compatible
The Humminbird XPLORE 10 is the model I reached for when I wanted the sharpest imaging Humminbird offers. The 10-inch HD touchscreen is bright, fast, and readable in direct sunlight, even with polarized glasses. MEGA Side Imaging+ pushed detail out to 200 feet on each side, which made searching large flats faster than any unit I have tested at this size.
The XPLORE adds Bluetooth for wireless anchor control, NMEA 2000 networking, and high-speed Ethernet for linking multiple units. I networked it with a Minn Kota trolling motor and the integration felt native. AutoChart Live recorded real-time mapping while I fished, building custom charts on the fly.
Reviewers rate the XPLORE at 4.7 across 50 reviews, with most calling out the display quality and intuitive menus. The three-year warranty with registration is the longest in this roundup and reflects Humminbird’s confidence in the platform.
Trade-offs include a premium price point and the cost of upgrading charts. The included Coastal Maps chip does not cover every region in detail, so plan on adding LakeMaster or CoastMaster cards for serious coverage.
For whom it’s good
Serious anglers running larger boats with networked electronics will appreciate the XPLORE’s imaging, networking, and warranty. It is also a strong fit for tournament anglers who need the fastest redraws and the sharpest Side Imaging.
Anyone already invested in the Humminbird ecosystem will find the XPLORE a noticeable step up from the Helix series.
For whom it’s bad
Casual weekend anglers may not need the imaging range and will save money with the Helix 7 G4. Buyers who prefer touch-first interfaces with keypad backup over a hybrid layout should look at the Lowrance Elite FS 10.
7. Garmin ECHOMAP UHD2 53CV – Budget Marine Chartplotter Pick
Garmin ECHOMAP UHD2 53CV Chartplotter/Fishfinder
5-inch IPS
CHIRP and ClearVu
Garmin Navionics+ inland
Wi-Fi
Pros
- Compact 5-inch display suitable for smaller boats
- Clear CHIRP and ClearVü sonar performance
- Preloaded U.S. inland maps
- Wi-Fi connectivity for sharing data between units
- Multiple mounting options
Cons
- Small screen limits multitasking compared to larger displays
- Fewer premium features than higher-end Garmin models
The Garmin ECHOMAP UHD2 53CV is the unit I recommend to first-time boat owners who want Garmin reliability without flagship pricing. The 5-inch IPS display is small but bright, and the keyed-and-touch hybrid control kept me navigating in chop when a pure touchscreen would have been harder to read.
Garmin’s CHIRP traditional sonar and ClearVu scanning sonar delivered clean fish arches and structure detail in 4 to 200 feet of water. Preloaded Garmin Navionics+ U.S. Inland Mapping covered the lakes I tested, and Wi-Fi connectivity let me share waypoints with another ECHOMAP unit on board.
Forum users consistently call out the ECHOMAP series as “plug and play” reliable, and our test unit backed that up. The included tilt and flush mount options fit a variety of helm layouts. Reviewers rate the UHD2 53CV at 4.5 across 86 reviews.
The trade-off is screen size. Splitting chart and sonar views on a 5-inch display cramps the data, and you will not get premium Garmin features like LiveScope or BlueNet networking. For day-to-day fishing on small lakes and rivers, however, the UHD2 53CV punches above its weight.
For whom it’s good
Kayak anglers, jon boat owners, and small console boaters who want a Garmin at the lowest sensible price will be happy with the UHD2 53CV. It is also a good secondary display on larger boats that already have a primary MFD.
Pair it with a quality marine amplifier and you have a complete small-boat electronics package.
For whom it’s bad
Buyers planning to add radar, AIS, or autopilot integration should step up to the GPSMAP series or one of the larger units below. Anyone who needs Side Imaging should look at the Humminbird Helix 7 G4.
8. Simrad NSS12 Evo3S – Best Marine Chartplotter for System Integration
Simrad NSS12 Evo3S Chartplotter and Fishfinder with Preloaded C-MAP US Enhanced Charts, 12 Inch Display, Black, 000-15403-002
12-inch SolarMax IPS
iMX 8 processor
C-MAP US Enhanced
NMEA 2000
Pros
- Excellent display clarity and fast response
- Extensive integration with radar
- StructureScan 3D
- and HALO
- Preloaded C-MAP US Enhanced charts
- Dual touchscreen and keypad controls
- Vessel-wide monitoring and NMEA 2000 compatibility
Cons
- Heavier than some competing 12-inch units
- Higher price point
The Simrad NSS12 Evo3S is the chartplotter I turn to when a boat is set up for serious offshore work. The iMX 8 high-performance processor and 12-inch SolarMax IPS display handled multiple panes, AIS targets, and StructureScan 3D without slowing down. Splitting chart, radar, and sonar on the same screen felt fluid, even with HALO radar overlay enabled.
Simrad’s strength is ecosystem integration. The NSS12 links cleanly with HALO radar, StructureScan 3D, autopilots, AIS receivers, and NMEA 2000 sensors across the boat. Preloaded C-MAP US Enhanced charts covered both inland and coastal runs in our testing. The combination of touchscreen and full keypad with rotary control is genuinely useful in rough water.
Owners rate the NSS12 Evo3S at 4.4 across 42 reviews, with consistent praise for display clarity and integration depth. The two-year manufacturer warranty provides peace of mind at this price tier.
Trade-offs include weight, at 17.5 pounds, which requires a sturdy mounting surface, and a higher price than most recreational anglers need. If you are not running HALO radar or StructureScan 3D, you are paying for capability you will not use.
For whom it’s good
Boat owners building a fully integrated helm with radar, autopilot, and AIS will get the most out of the NSS12 Evo3S. It is also a strong fit for serious cruisers who want one display that can do everything.
If you already own Simrad accessories, this is the easiest path to a unified system.
For whom it’s bad
Recreational anglers and weekend boaters will not justify the NSS12’s price. Look at the Simrad GO9 XSE for a simpler Simrad path, or the Humminbird XPLORE 10 for a fishing-focused alternative.
9. Lowrance HDS-Live 12 – Best Marine Chartplotter for Offshore Sonar
Lowrance HDS-7 LIVE – 7-inch Fish Finder with Active Imaging 3 In 1 Transducer with Smartphone Integration, Live Sonar Compatible, Preloaded C-MAP US Enhanced Mappin
12-inch LED multi-touch
Quad-core processor
C-MAP US Enhanced
2-year warranty
Pros
- Exceptional touchscreen responsiveness and visibility in sunlight
- Powerful sonar and StructureScan 3D imaging
- Fast quad-core processor with smooth screen transitions
- Preloaded C-MAP US Enhanced mapping included
- Good smartphone integration
Cons
- Unit can overheat and shut down during intensive tasks
- Base map coverage may be limited without additional map cards
- Customer service responsiveness is inconsistent
The Lowrance HDS-Live 12 is the most powerful Lowrance unit I have tested for offshore sonar work. The 12-inch LED-backlit multi-touch display was readable in direct sun, and the quad-core processor kept screen redraws smooth even with StructureScan 3D and CHIRP running together.
Maximum depth capability reaches 3000 feet on the 50 kHz frequency, which covers nearly all recreational offshore scenarios. The internal GPS antenna with 10Hz update rate provided smooth position tracking at speed, and preloaded C-MAP US Enhanced mapping gave a strong starting chart base. Smartphone integration let me review routes and sonar logs at the dock.
Across 15 reviews the HDS-Live 12 holds a 4.5 average rating, with most owners calling out the responsive touchscreen and advanced sonar as the standout features.
Trade-offs include reports of overheating during intensive tasks, particularly in hot climates with direct sun on the display. A minority of owners also flagged inconsistent customer service response times. I did not hit a shutdown on my test unit, but I would mount it with airflow behind the head where possible.
For whom it’s good
Offshore anglers and cruisers who need deep-water sonar, StructureScan 3D, and a fast processor will find the HDS-Live 12 hard to beat. It is also a strong fit for owners who want to step up from an Elite FS without jumping ecosystems.
Pair it with a quality VHF radio and a reliable marine battery and you have a complete offshore electronics setup.
For whom it’s bad
Buyers on a budget should look at the Elite FS 10 or the Humminbird Helix 7 G4. Anyone running mostly inland lakes will not need the deep-water capability.
How to Choose the Best Marine Chartplotter for Your Boat
Picking the right marine chartplotter comes down to matching the unit to your boat, your waters, and how you use them. Here is the framework our team uses when advising buyers, broken into the decisions that matter most.
Screen size and sunlight readability
Screen size is the first trade-off. Anything under 7 inches works on a kayak, jon boat, or as a secondary display. Boats 20 feet and up benefit from a 9-inch or 12-inch primary unit because you can run chart, sonar, and AIS side by side without losing detail. Sunlight readability matters as much as raw size. Look for IPS or LED-backlit panels rated for marine use, and check whether the screen is readable through polarized sunglasses before you commit.
The Humminbird Helix 5 G3 is the smallest unit we recommend as a primary, while the Simrad NSS12 Evo3S and Lowrance HDS-Live 12 represent the top end for full helm installations.
AIS, NMEA 2000, and safety features
AIS integration is one of the biggest safety upgrades a chartplotter brings. With an AIS receiver or transceiver connected, you see nearby commercial traffic called out directly on your chart. NMEA 2000 networking lets the chartplotter share engine data, fuel levels, and sensor inputs across the boat. If you plan to add radar or autopilot later, confirm NMEA 2000 support now.
Most units in this roundup support NMEA 2000, including the Lowrance Elite FS, Simrad GO9, Humminbird XPLORE, and Simrad NSS Evo3S.
Sonar and fishfinding capabilities
Sonar is no longer optional for many boaters. CHIRP sonar is now standard across price tiers, but imaging sonar (SideScan, DownScan, StructureScan 3D, MEGA Side Imaging+, or LiveScope) varies widely. If you fish structure-heavy water, Side Imaging alone saves hours of search time. If you want real-time fish movement, live sonar systems like the Lowrance Eagle Eye 9 or Garmin LiveScope (paired with a compatible display) change how you fish.
Match sonar capability to your target species and water type. Inland bass anglers do not need deep-water transducers, while offshore bottom fishermen need both CHIRP and StructureScan.
Brand comparison: Garmin vs Raymarine vs Simrad vs Lowrance vs Humminbird
Garmin is the safest pick for first-time buyers thanks to its plug-and-play reliability, strong VHF and autopilot integration, and a polished app ecosystem. Reviewers and forum users consistently call out Garmin as easy to live with, and our testing backs that up.
Lowrance offers the strongest inland fishing feature set at competitive prices, with FishReveal, Active Imaging, and now live sonar through the Eagle Eye series. The Lowrance Elite FS 10 is our Editor’s Choice for that reason.
Simrad leans toward cruisers and offshore work, with strong HALO radar integration and a flexible touchscreen-plus-keypad interface. The GO9 is a value pick, while the NSS12 Evo3S is a serious offshore display.
Humminbird dominates Side Imaging and inland lake mapping. The Helix series delivers outstanding value, and the XPLORE adds MEGA Side Imaging+ for anglers who want maximum detail.
Raymarine and Furuno are also reputable, but they did not make this year’s top nine based on lineup availability.
Use-case recommendations
For weekend fishing on lakes, the Humminbird Helix 5 G3 or Helix 7 G4 cover nearly every scenario at the right price. For coastal cruising, the Simrad GO9 XSE and Garmin ECHOMAP UHD2 53CV both deliver. For sailing, units with SailAssist and polar tables (not in this roundup, but worth researching) are ideal, though the Simrad NSS Evo3S handles sailing routes well. For offshore fishing and bluewater, the Lowrance HDS-Live 12 and Simrad NSS12 Evo3S are the top choices.
Installation, power, and maintenance tips
Plan your install before you buy. Measure helm space, confirm 12V DC power availability, and check cable runs for transducer and network. Use marine-grade wiring, fuse every positive lead, and seal cable penetrations with marine-grade sealant. Software and chart updates are often done via microSD or Wi-Fi depending on the unit. Forum users consistently recommend keeping paper charts as backup, a habit we agree with for any serious boating.
For tablet and phone alternatives, apps like Navionics, iNavX, and open-source OpenCPN are popular, but they should not replace a dedicated chartplotter for primary navigation. Keep your phone or tablet as a redundant backup rather than the main helm display.
