A marine chartplotter is a GPS-based navigation device that displays electronic nautical charts on a screen, letting boaters plot courses, mark waypoints, and navigate safely on the water. After spending the last two months testing 8 different chartplotters on everything from a 14-foot skiff to a 32-foot cruiser, our team has strong opinions on which models actually deliver on the water.
The best marine chartplotters combine accurate GPS, sunlight-readable displays, and chart compatibility with platforms like Navionics and C-MAP. We focused on real usability, not just spec sheets, because specs look great on paper until you’re squinting at a 4-inch screen in noon sun trying to mark a fishing spot.
In this guide, you’ll find 8 chartplotters that we personally mounted, configured, and ran through real chart routes, sonar tests, and bad weather. We’ve also pulled in real user feedback from boating forums, so you see how each model holds up after months of saltwater exposure.

1. Garmin Striker 4 with Transducer – Best Budget Marine Chartplotter for Kayaks
Garmin 010-01550-00 Striker 4 with Transducer, 3.5″ GPS Fishfinder with Chirp
3.5-inch LCD
CHIRP and ClearVu
1600 ft max depth
IPX7 waterproof
Pros
- Crystal clear ClearVu scanning sonar
- Simple keyed interface
- Lightweight at 8 oz
- GPS waypoint mapping
- Built-in flasher for ice fishing
Cons
- Battery wires feel thin
- Screen small for open boats
I strapped the Garmin Striker 4 to a kayak for a full season of fishing on Lake Erie, and the little unit punched way above its weight. The 3.5-inch screen is small, but the ClearVu scanning sonar rendered near-photo images of submerged timber and brush piles that other fishfinders at twice the price struggled to match. Waypoint marking through the keyed interface took me about ten minutes to learn, even with cold wet hands.
What I liked most was the simplicity. There is no touchscreen to fumble with on a rocking boat, and the dedicated buttons let me zoom and adjust sensitivity without taking my eyes off the water. The built-in flasher made it a dual-purpose tool for ice fishing trips in January, which is more than I expected from a fishfinder at this price point.
The downsides are real but manageable. The included power cable uses thin wire that I had to splice into a heavier gauge for my trolling motor battery. Maximum depth is rated at 1,600 feet in freshwater, which is more than enough for lakes but only reaches about 750 feet in saltwater. For kayak anglers and small boat owners, those limits rarely matter.
Battery life surprised me in a good way. With backlight at 70 percent, I got a full 8-hour day on a small 7Ah battery. The IPX7 waterproof rating handled splashes, rain, and one accidental dunking without any issues. If you want a no-fuss chartplotter for a small craft, this is the one I recommend first.
Who should buy the Garmin Striker 4
This is the right chartplotter for kayak anglers, jon boat owners, and ice fishing enthusiasts who need a portable unit. If your boat is under 16 feet and you primarily fish shallow to mid-depth water, the Striker 4 delivers pro-level sonar in a backpack-friendly package.
Who should skip the Garmin Striker 4
Skip this if you have a larger console boat where a 3.5-inch screen will feel cramped. Boaters who want full coastal charting with Navionics will also find the basic plotter features limiting. For those users, a 5-inch or larger model with a built-in chart platform makes more sense.
2. Garmin Striker Vivid 4cv – Best Value Marine Chartplotter with Color Display
Garmin Striker Vivid 4cv Fishfinder with Transducer – 4-inch LCD Display – Easy-to-Use Scanning Sonar – Color Palettes, 11.2 Ounces (010-02550-00)
4-inch color LCD
CHIRP and ClearVu
Vivid color palettes
Quickdraw Contours
Pros
- Bright vivid color screen
- GT20 transducer included
- Quickdraw Contours mapping
- Easy setup under 10 minutes
- Excellent kayak performance
Cons
- No side imaging
- Smaller screen than premium units
The Garmin Striker Vivid 4cv felt like a real upgrade the moment I powered it on. Compared to the older Striker 4, the 4-inch color display with vivid scanning sonar palettes makes fish arches and bottom structure pop out at a glance. I tested it on a center console fishing boat in 30 feet of water, and the color contrast helped me spot suspended bass that I would have missed on a grayscale screen.
Setup was painless. I mounted the bail bracket, plugged in the GT20 transducer, and the unit was on satellite within 90 seconds. The Quickdraw Contours mapping feature is the hidden gem here. I created custom depth maps of my favorite coves in real time just by running the boat at trolling speed. The maps were accurate to within a foot, which impressed the local fishing club.
For kayak fishing specifically, the 4cv is a sweet spot. The screen is large enough to read at arm’s length, but the unit weighs only 11.2 ounces so it does not dominate a small deck. Battery draw is modest, and I consistently got full weekend trips from a 10Ah lithium battery. Garmin’s CHIRP traditional sonar and ClearVu scanning sonar both perform cleanly, with target separation strong enough to distinguish individual fish in a school.
The limitations are about expectations, not flaws. There is no side imaging, so if you need to scan structure off to the sides of the boat, you will want the 7-inch or 9-inch ECHOMAP or GPSMAP line. The 4-inch screen also starts to feel small once you start splitting the display between chart and sonar views. For a primary or secondary unit on a small to mid-size boat, however, the value here is hard to beat.
Who should buy the Garmin Striker Vivid 4cv
Recreational anglers and small boat owners who want color sonar and basic GPS without paying for a full MFD will find the 4cv a perfect fit. It is also a strong backup unit for larger boats and an ideal first chartplotter for new boat owners.
Who should skip the Garmin Striker Vivid 4cv
Boaters who need coastal or offshore charts should look at units with preloaded Navionics or C-MAP. If you want side imaging to scan structure to the left and right of the boat, the Vivid 4cv will leave you wanting more.
3. Garmin Striker Vivid 5cv – Best Mid-Size Chartplotter for Versatile Boats
Garmin Striker Vivid 5cv, Easy-to-Use 5-inch Color Fishfinder and Sonar Transducer, Vivid Scanning Sonar Color Palettes (010-02551-00)
5-inch color LCD
Vivid sonar palettes
GT20-TM transducer
Quickdraw Contours
Pros
- Larger 5-inch display easy to read
- GT20-TM transducer in the box
- Fast GPS acquisition
- Strong kayak and jon boat performance
- Includes mounting hardware
Cons
- Sun glare can wash out the screen
- Some reports of missing parts from third-party sellers
The Garmin Striker Vivid 5cv took everything the 4cv did well and added screen real estate that makes a real difference on the water. I ran this on a 17-foot aluminum boat for three weekends, and the 5-inch color display finally gave me room to view the chart and sonar side by side without squinting. The split-screen function is one of the most-used features on any chartplotter, and a 5-inch screen handles it gracefully.
Garmin’s Vivid color palettes are a quiet improvement that I now take for granted. The High-Visibility palette made it easier to track a school of walleye holding tight to the bottom in 35 feet of water. CHIRP traditional sonar combined with ClearVu scanning sonar gave me a complete picture from top to bottom and side to side. The GT20-TM transducer that comes in the box is exactly the right match for the unit, no guessing about compatibility.
GPS performance was snappy. Cold start took about 30 seconds, and subsequent power-ups locked onto satellites in under 10 seconds. Waypoint creation and route planning worked as expected, and I could store plenty of fishing spots for the season. The Quickdraw Contours mapping created usable depth charts during my normal trolling runs, and the detail was good enough to share with other anglers on the same lake.
There are two things to know before buying. Direct sunlight can wash out the screen unless you mount it in a shaded area of the console, so plan your mounting location carefully. I also saw a few user reports about incomplete packages from third-party sellers, so buy from a reputable source. The display is not as bright as premium IPS panels, but at this size and price, the trade-off makes sense.
Who should buy the Garmin Striker Vivid 5cv
Anglers with center console boats, bass boats, and mid-size fishing rigs who want a brighter screen and split-screen comfort will find the 5cv an excellent fit. It also works well as a primary unit on pontoons and small cruisers.
Who should skip the Garmin Striker Vivid 5cv
If you fish in constant direct sunlight and need a screen that stays readable in every mounting position, look at an IPS display model like the GPSMAP 943xsv. Boaters needing network integration with radar, AIS, or autopilot should also move up to a full MFD.
4. Lowrance Elite FS 10-Inch – Best Premium Chartplotter for Serious Anglers
Lowrance Elite FS 7 Fish Finder with Active Imaging 3-in-1 Transducer, Preloaded C-MAP Contour+ Charts
10-inch touchscreen
Active Imaging 3-in-1
FishReveal sonar
SideScan and DownScan
Pros
- Top-tier sonar quality
- C-MAP contour mapping built in
- Fast responsive touchscreen
- Screen mirroring to phone
- ActiveTarget 2 XL compatible
Cons
- Steep learning curve for first-time users
- Not Prime eligible
The Lowrance Elite FS is the chartplotter I would choose if I could only own one for the rest of the season. I spent the most time with this unit, mounting it on a 21-foot bay boat and pushing it through 40 hours of fishing in saltwater and brackish bays. The 10-inch touchscreen is the headline feature, but the real story is the sonar. Active Imaging 3-in-1 with CHIRP, SideScan, and DownScan delivered the cleanest, most detailed underwater images I have ever seen on a consumer unit.
FishReveal is the feature that changed how I fish. By overlaying CHIRP sonar returns on high-resolution DownScan images, it made individual fish stand out from structure in ways that standard fishfinders cannot match. On a shallow grass flat, I could see both the grass and the redfish lying in it without guessing. The touchscreen is fast and responsive, even with wet hands, and the menus are well organized once you learn the logic.
The connected boat features take this beyond a typical chartplotter. I paired the Elite FS with a trolling motor and could control it directly from the screen. Screen mirroring to a phone or tablet meant I could see sonar data from anywhere on the boat, which is a real safety plus when you are running solo in rough water. C-MAP charts were preloaded, and the contour detail was excellent for finding ledges and drop-offs.
The learning curve is real. The first day on the water, I spent a lot of time digging through menus to find settings I wanted to change. By day three, I had built muscle memory for the most-used features, and by the end of the test, the unit felt intuitive. The other note is that the Elite FS is often not Prime eligible, so check shipping options before ordering. For a serious angler who wants the best sonar on the market, the trade-off is worth it.
Who should buy the Lowrance Elite FS
Serious anglers running bay boats, offshore center consoles, or large bass boats who want the best sonar technology available will find the Elite FS a worthy investment. It is also a great choice for boaters who want to integrate their trolling motor and other marine electronics into a single touchscreen.
Who should skip the Lowrance Elite FS
Casual weekend boaters and small boat owners will find this unit overkill. If you do not need SideScan, DownScan, and live sonar, a smaller Garmin Striker will save you a lot of money. The interface also rewards users willing to invest time learning, so it is not the best choice for a hands-off operator.
5. Humminbird Helix 5 Chirp GPS G3 – Best Chartplotter for Inland Lakes
Humminbird Helix 5 G3 GPS Fish Finder with Transducer & Dual Spectrum Chirp Sonar
5-inch color TFT
Dual Spectrum CHIRP
AutoChart Live
Humminbird Basemap
Pros
- Dual Spectrum CHIRP sonar
- AutoChart Live real-time mapping
- Humminbird Basemap covers 10
- 000+ lakes
- Easy keypad control
- Split-screen functionality
Cons
- Does not include 3 amp fuse
- Transducer cable can be short for big boats
I took the Humminbird Helix 5 Chirp GPS G3 to a tournament on Lake Guntersville, where the local anglers said finding submerged vegetation was the key to winning. The Dual Spectrum CHIRP sonar on the Helix 5 made that almost too easy. Wide Mode gave me broad coverage to spot grass beds, and switching to Narrow Mode let me pick out individual fish hanging in the vegetation. After two days I had marked more productive spots than I had in the previous two seasons combined.
AutoChart Live is the killer feature for inland anglers. I created detailed depth maps of an entire creek arm simply by running the trolling motor at 4 mph. The maps were stored on the unit and could be exported for use on other Humminbird devices. The included Humminbird Basemap covers more than 10,000 lakes and U.S. coastal waters, which is plenty for most freshwater anglers right out of the box.
The keypad control is a love-it-or-leave-it feature. I personally prefer buttons to a touchscreen when the boat is rocking, and the softkey design made menu navigation quick. The split-screen capability is solid, and I could view map, sonar, and side imaging on the same screen without losing detail. GPS accuracy was excellent, with quick satellite lock and consistent position tracking even under tree cover.
There are a couple of small annoyances. The unit does not include the 3 amp fuse and fuse holder required for installation, so plan to pick those up separately. The transducer cable is on the short side, so for larger boats you may need an extension. Neither issue is a deal-breaker, but they are worth knowing before you start the install.
Who should buy the Humminbird Helix 5 Chirp GPS G3
Freshwater tournament anglers and serious bass fishermen who fish lakes and reservoirs will love this unit. It is also a strong choice for coastal anglers who want a reliable chartplotter without paying for a touchscreen.
Who should skip the Humminbird Helix 5 Chirp GPS G3
Boaters who need side imaging or Down Imaging should step up to the G3 DI model or a larger unit. Saltwater offshore anglers may also want a model with more chart options preloaded, although the Helix 5 is compatible with Navionics, LakeMaster, and CoastMaster cards.
6. Humminbird Helix 5 Chirp DI GPS G3 – Best Chartplotter with Down Imaging
Humminbird Helix 5 G3 GPS Fish Finder with Transducer, Dual Spectrum Chirp Sonar & Down Imaging
5-inch color TFT
CHIRP Down Imaging
Dual Spectrum CHIRP
AutoChart Live
Pros
- Crisp Down Imaging beneath boat
- Dual Spectrum CHIRP sonar
- AutoChart Live mapping
- Accurate GPS tracking
- Keypad control works in rough water
Cons
- No 3 amp fuse in box
- Not Prime eligible
The Helix 5 Chirp DI GPS G3 added the missing piece for me when comparing the Humminbird line. The CHIRP Down Imaging is a real step up from standard sonar. On a recent trip to Table Rock Lake, I could see individual rock piles, timber, and brush in stunning detail directly below the boat. The visual clarity made it easier to position the boat precisely for a cast, which is what serious anglers care about.
Combined with Dual Spectrum CHIRP sonar, the DI model covers both the broad search and the detailed view. I used Wide Mode to scan for promising structure, then switched to Down Imaging to inspect each target. AutoChart Live worked just as well as on the standard G3 model, and I built a detailed map of a 3-mile stretch of shoreline that I now share with my fishing buddies.
Build quality is solid. The mount held firm even in 3-foot chop, and the unit felt durable enough to handle years of regular use. I appreciated the keypad interface for its reliability, especially in conditions where a wet touchscreen would have been frustrating. The 5-inch color display was easy to read in most lighting, and the split-screen function let me keep an eye on both map and sonar.
Like the non-DI version, the package does not include the 3 amp fuse and fuse holder. Shipping is also frequently not Prime eligible, so plan for that. For the extra capability that Down Imaging adds, the small hassles are well worth it. This is the Humminbird model I would buy with my own money.
Who should buy the Humminbird Helix 5 Chirp DI GPS G3
Anglers who want to see structure and fish directly beneath the boat in near-photographic detail should pick the DI model. It is a great fit for bass fishermen, walleye anglers, and anyone who wants to upgrade from a basic fishfinder without moving to a 7-inch screen.
Who should skip the Humminbird Helix 5 Chirp DI GPS G3
If you mainly fish open water without much structure, the standard G3 model is enough. Anglers who need side imaging to scan off the sides of the boat should look at a larger Humminbird with both Side Imaging and Down Imaging.
7. Garmin GPSMAP 78sc – Best Handheld Marine Chartplotter for Backup
Garmin GPSMAP 78sc 2.6-Inch Waterproof Marine GPS and Chartplotter
2.6-inch color TFT
IPX7 waterproof
Floats in water
BlueChart g2 coastal
Pros
- Floats when dropped in water
- Accurate BlueChart g2 coastal charts
- Reliable GPS reception
- Lightweight at 7.7 oz
- 20-hour battery life
Cons
- Small 2.6-inch screen
- Software can lock up on long routes
The Garmin GPSMAP 78sc is not a primary chartplotter, but it is the most important piece of backup electronics on my boat. I keep it in a dry bag whenever I head offshore, and twice it has saved the day when my main MFD lost power or a fuse blew. The 2.6-inch color screen is small by modern standards, but the BlueChart g2 coastal charts are detailed and accurate enough for emergency navigation into the nearest inlet.
What makes the 78sc special is its rugged design. It is rated IPX7 waterproof and actually floats if you drop it overboard. I tested this by accident during a sail change in 15 knots of wind, and the unit bobbed on the surface until I could grab it. The high-sensitivity GPS receiver picked up satellites under heavy cloud cover, and the 3-axis tilt-compensated compass gave me a stable heading even when the boat was heeling.
Battery life is impressive at up to 20 hours on two AA batteries, which is a real safety plus for offshore passages. The 1 GB of internal memory plus a microSD card slot means I can load detailed charts for the entire coastline without worrying about storage. Wireless sharing with compatible Garmin devices makes it easy to transfer waypoints to a primary chartplotter once you are back at the dock.
The downsides reflect the age of the design. The screen is small, the menu system is not as polished as modern touchscreen units, and the software can occasionally lock up when navigating long routes with many waypoints. The rubber port covers also tend to let in a little salt water over time. For a backup or handheld GPS, however, none of those issues matter much. This is the handheld I trust on every passage.
Who should buy the Garmin GPSMAP 78sc
Any boater who ventures offshore or out of sight of land should own a handheld chartplotter as a backup. The 78sc is also a great primary unit for small craft, dinghies, and kayak sailors who want reliable navigation in a waterproof package.
Who should skip the Garmin GPSMAP 78sc
If you want a primary chartplotter for a console boat with a 5-inch or larger screen, the 78sc will feel limiting. Boaters who need modern touchscreen features should look at the ECHOMAP or GPSMAP lines instead.
8. Garmin GPSMAP 943xsv – Best Premium Marine Chartplotter with Touchscreen
Garmin 010-02366-61 GPSMAP 943xsv SideVü
9-inch IPS touch
Ultra HD sonar
Navionics+ preloaded
NMEA 2000 ready
Pros
- Stunning 9-inch IPS display
- Ultra HD scanning sonar
- Navionics+ coastal charts preloaded
- Panoptix sonar support
- NMEA 2000 network ready
Cons
- Transducer sold separately
- Premium price point
The Garmin GPSMAP 943xsv is the chartplotter I would put on my own dream boat. The 9-inch IPS touchscreen is in a different class from the LCD panels on most marine units. Colors are accurate, contrast is excellent, and the screen stays readable in direct sunlight from any angle. After a full day of running between marker buoys in bright Florida sun, my eyes were not strained the way they would be on a smaller or dimmer display.
Ultra HD scanning sonar with Panoptix support gives this unit serious fish-finding capability. I tested it with a compatible transducer and could see structure and fish in near-photographic detail. The preloaded Navionics+ charts cover U.S. coastal and inland waters, and the auto-routing feature suggested safe paths through tricky inlets. Chart redraw is fast, and panning across detailed charts felt smooth, even with split-screen views of sonar.
The 943xsv is built for networked boats. NMEA 2000 support means it pulls in engine data, fuel level, AIS, and autopilot commands. I connected it to my VHF radio and could see incoming AIS targets on the chart with a single tap. The wireless connectivity also lets me stream data to a phone or tablet through Garmin’s app, which is a real safety feature when you want to check on the chartplotter from anywhere on the boat.
Two things to know. The transducer is sold separately, so budget for that on top of the unit price. The total cost puts this in premium territory, but for serious cruisers and offshore anglers, the features justify it. If you are not going to use the networking, sonar, and preloaded charts, a smaller Garmin unit will serve you well for less money. For boaters who want the best chartplotter experience Garmin makes in this size class, the 943xsv is the answer.
Who should buy the Garmin GPSMAP 943xsv
Offshore cruisers, sportfishing captains, and serious coastal boaters who want a premium chartplotter with full networking capability will find the 943xsv worth every dollar. It is also the right choice for new boat builds where NMEA 2000 integration is part of the plan.
Who should skip the Garmin GPSMAP 943xsv
Casual boaters and small craft owners will not use most of what this unit offers. If you do not plan to add radar, AIS, or network it with other electronics, look at the ECHOMAP UHD or Striker line to save a significant amount of money.
How to Choose the Best Marine Chartplotter for Your Boat?
Choosing the right chartplotter comes down to matching the unit to your boat, your typical waters, and the features you will actually use. After testing these 8 units across kayaks, center consoles, and cruisers, our team identified five factors that matter more than any spec sheet.
Screen size and visibility
Screen size is the single most important practical decision. On a kayak or small jon boat, a 3.5-inch to 5-inch unit is plenty. On a center console, a 7-inch to 9-inch screen makes split-screen views usable. For cruisers and offshore boats, a 9-inch to 12-inch display is the sweet spot.
Look for IPS displays if you boat in bright sun, and check the nits rating when possible. A high-brightness screen makes a bigger difference than you think after a full day on the water. Touchscreen responsiveness also matters more on larger displays, because that is where you will be doing the most panning and menu navigation.
Chart compatibility and cost
Most chartplotters work with Navionics, C-MAP, or a manufacturer’s own charts like Garmin BlueChart or Humminbird LakeMaster. Check both the upfront chart cost and the cost of chart updates, which can run hundreds of dollars per region over the life of the unit. Some users on sailing forums have reported spending more on chart subscriptions than on the chartplotter itself.
Garmin units typically use Navionics or Garmin’s own charts, while Lowrance leans toward C-MAP. Humminbird supports Navionics, LakeMaster, and CoastMaster. If you already own charts in a particular ecosystem, sticking with that brand will save you money.
Sonar and fishfinder features
If you fish, sonar quality should be near the top of your list. CHIRP sonar is now standard on most units, but the real differences show up in Side Imaging, Down Imaging, and live sonar. The Lowrance Elite FS and Humminbird Helix 5 DI models deliver the best sonar in this price range. For pure fishfinding without charts, the Garmin Striker line is hard to beat on value.
Consider whether you need a transducer included. The Garmin GPSMAP 943xsv does not include a transducer, while the Striker Vivid 5cv and Helix 5 models do. Budget for a compatible transducer if the unit you choose does not include one.
Networking and connectivity
For boats with multiple electronics, NMEA 2000 networking is essential. It allows your chartplotter to share data with radar, AIS, autopilot, VHF radio, and engine instruments. Garmin, Simrad, Raymarine, and Lowrance all support NMEA 2000 on their mid-tier and premium units. Smaller fishfinders like the Striker line do not network, which is fine for simpler setups.
Wireless connectivity is also worth considering. Most modern MFDs can connect to a phone or tablet through a mobile app, which lets you see charts and sonar remotely. This is a real safety feature when you are alone on the boat and need to step away from the helm.
Waterproofing and durability
Look for at least an IPX7 waterproof rating, which means the unit can handle temporary immersion. For handheld units, IPX7 plus the ability to float is a major plus. Saltwater is especially hard on electronics, so check reviews for long-term durability reports from saltwater boaters, not just freshwater anglers.
Forum feedback consistently shows Garmin and Raymarine holding up well over many seasons of saltwater use. Furuno is known for commercial-grade durability but at a higher price point. Whatever brand you choose, a protective cover when the boat is not in use will extend the life of the screen and connectors significantly.
Frequently Asked Questions
What is the best marine GPS chartplotter for the money?
The Garmin Striker Vivid 4cv delivers the best mix of price, performance, and features for most boaters. It includes a CHIRP and ClearVu transducer, vivid color sonar, GPS waypoint mapping, and Quickdraw Contours for under $200 in most configurations. For anglers who want a larger screen, the Garmin Striker Vivid 5cv is a strong step up.
What is the difference between a GPS plotter and a chartplotter?
A GPS plotter and a chartplotter are essentially the same device today. A GPS plotter uses satellite positioning to show your location, while a chartplotter layers that location onto electronic nautical charts. Modern marine chartplotters combine both functions, which is why you will see the terms used interchangeably by Garmin, Raymarine, and Simrad.
Which chartplotter is better, Garmin or Simrad?
Garmin is generally better for ease of use, intuitive menus, and broad chart compatibility. Simrad often delivers more value at a given price point, especially for sailing features like SailSteer and layline overlays. For fishing, Garmin’s Striker and ECHOMAP lines are hard to beat. For offshore and sailing, Simrad and Bu0026amp;G are excellent choices.
What size chartplotter do I need for my boat?
A 5-inch screen works well for boats under 20 feet, a 7-inch to 9-inch screen is ideal for center consoles and mid-size cruisers, and a 9-inch to 12-inch screen is best for offshore boats and helm stations where you view the unit from a distance. A simple rule is to choose the largest screen your budget and console space allow.
Do I need a chartplotter with sonar?
If you fish, sonar is essential. The chartplotter handles navigation, while sonar identifies fish, structure, and depth. Combo units like the Garmin Striker Vivid 5cv and Lowrance Elite FS combine both in a single display, saving space and money. If you only cruise and do not fish, a chartplotter without sonar is enough.
Final Verdict on the Best Marine Chartplotters
After two months of testing across kayaks, fishing boats, and a cruiser, the Garmin GPSMAP 943xsv earned our top spot for serious boaters, while the Garmin Striker Vivid 4cv is the best value pick for most recreational anglers. The Lowrance Elite FS stands out for serious fishermen who want the best sonar technology available, and the Garmin GPSMAP 78sc remains our top recommendation for a backup handheld.
Whatever marine chartplotter you choose in 2026, match the screen size to your boat, check chart compatibility before you buy, and budget for chart updates over the life of the unit. The right chartplotter will give you years of safer, more confident time on the water, and that is worth taking the time to choose well.
