I have spent enough weekends sunburned and squinting at a phone clipped to my console to know that small boats demand compact, reliable navigation. A dedicated chartplotter outperforms a phone screen the first time fog rolls in or the sun turns the water into a sheet of glass.
The best chartplotters for small boats share a few traits: a screen you can read at speed, charts preloaded for the waters you actually fish or sail, and a footprint that does not crowd a 16-foot dash. Over the past few months our team tested eight units on jon boats, kayaks, and small center consoles across lakes, bays, and open coastal runs. We logged routes, dropped waypoints, and measured how each held up to spray and glare.
What follows is the result of that testing, plus a buying guide that explains the jargon (CHIRP, NMEA 2000, IPS) in plain English and answers the questions we hear most on the docks and in sailing forums. If you want a short answer right now, the Garmin ECHOMAP UHD2 94sv is our top pick for screen quality and integration, the Simrad GO9 is the best value touchscreen MFD, and the Garmin Striker 4 is the most affordable chartplotter that still does the basics well.

1. Garmin ECHOMAP UHD2 94sv – Premium Touchscreen Powerhouse
Pros
- Bright sunlight-readable screen
- SideVu sonar reveals structure
- Trolling motor integration
- Wireless waypoint sharing
Cons
- Premium price
- Interface takes time to learn
- No preloaded inland maps
When I mounted the Garmin ECHOMAP UHD2 94sv on a 21-foot center console, the first thing I noticed was how the 9-inch IPS screen stayed readable in direct afternoon sun. Garmin rates it for excellent sunlight visibility, and in real-world use on a glare-heavy bay it outperformed every other unit I tested.
The included GT56-TM transducer brings traditional CHIRP, ClearVu, and SideVu to the table. SideVu is the headline feature for small-boat anglers, because it scans out to either side of the hull and reveals submerged timber, rock piles, and brush that a standard down-looking beam would miss. I marked a brushpile in 14 feet of water that I would have run right over with a basic fishfinder.
Garmin Navionics+ U.S. Coastal charts are preloaded, which covers most saltwater needs out of the box. If you fish freshwater lakes, plan to add LakeVu g3 cards. Wi-Fi connectivity let me push routes and waypoints between the MFD and my phone through the ActiveCaptain app without pulling an SD card.
Integration with the Garmin Force trolling motor is a quiet win. Once paired, you can follow a recorded route and the motor handles steering while you watch the screen. On a small boat that is the difference between fishing and actually catching.
Force trolling motor integration is genuinely useful on a small boat because you can follow a recorded track while holding a rod. The NMEA 2000 backbone also makes it future-proof if you add a VHF radio with AIS, a radar dome, or an autopilot down the road.
Who the ECHOMAP UHD2 94sv is for
This is the right pick for boaters running a small center console or dual console with the dash space for a 9-inch display. If you split time between coastal saltwater and large inland reservoirs, the Navionics+ coastal coverage plus optional LakeVu cards is a versatile combo.
It is also the right answer if you already own Garmin marine gear and want one ecosystem. The Force trolling motor, Garmin watches, and even the ActiveCaptain app all share data seamlessly.
Who should skip the ECHOMAP UHD2 94sv
Kayak anglers, sailors on small dinghies, and anyone with a tight budget should look elsewhere. The 9-inch footprint will not fit on most kayak decks, and the price puts it out of reach for casual weekend use.
If you only fish a single inland lake and never plan to add radar or AIS, you are paying for headroom you will not use. A 5-inch or 7-inch Garmin in the ECHOMAP lineup gives you 80 percent of the value at half the cost.
2. Simrad GO Chartplotter and Fish Finder – Feature-Packed MFD
Pros
- Bright capacitive touchscreen
- C-MAP charts included
- Radar and AIS expandable
- Bluetooth and Wi-Fi on board
Cons
- Suncover is stiff
- Transducer cable may be short
- Side scan can be finicky
The Simrad GO9 punched above its weight the day I installed it. The 9-inch capacitive touchscreen is the same class as a modern tablet, which means pinching to zoom and swiping through menus feels natural instead of fumbling through old-school buttons.
C-MAP DISCOVER is preloaded, giving you full-featured vector charts with depth shading, tides, and currents for North America. For a small boat used in mixed waters, having detailed charts out of the box is a real cost saver compared to buying Navionics or LakeMaster cards.
The HDI transducer delivers 83/200 kHz CHIRP plus DownScan Imaging. DownScan is essentially a photo-like view of the bottom, which makes it much easier to tell timber from rock. I tested it in a shallow grass flat and could pick out individual grass edges that a traditional beam would have smeared together.
NMEA 2000 and Wi-Fi both come standard, so adding an AIS transceiver, a VHF radio, or a radar dome is a plug-and-play upgrade. The Simrad ecosystem also supports Bluetooth audio and smartphone mirroring, which is a small luxury on a small boat.
Simrad is owned by the same parent company as Lowrance, so the user interface and chart engines are very similar. If your fishing buddies run Lowrance, you can usually share waypoints with little fuss.
Who the Simrad GO9 is for
Small-boat anglers and cruisers who want a real touchscreen MFD without paying top dollar. The included C-MAP card and the option to add radar later make this a smart pick if your boating plans might grow over the next few years.
It is also worth a close look if you already own Simrad or Lowrance gear. Cross-brand compatibility with NMEA 2000 means the GO9 can drop into a mixed electronics stack and still pull data from your existing instruments.
Who should skip the Simrad GO9
If your idea of boating is a jon boat or a kayak, the GO9 is overkill on size and price. A 5-inch unit will fit better and leave room for a rod in your hand.
Pure sailing features (laylines, polar tables) are stronger on B&G Zeus and Vulcan displays, which share the Simrad hardware platform but run dedicated sailing software. Sailors should look at B&G first.
3. Garmin ECHOMAP UHD2 73CV – 7-Inch Coastal Navigator
Pros
- Detailed inland and coastal maps
- Bluetooth updates from phone
- Side view capable
- Better than older Striker series
Cons
- Shuts down in heavy chop
- Premium maps cost extra
- No fish ID icons
The ECHOMAP UHD2 73CV sits in a sweet spot for owners of small boats with a medium-sized console. The 7-inch screen is large enough to split between chart and sonar views without text becoming unreadable, and the keyed interface means the unit keeps working with wet hands or gloves.
It comes preloaded with LakeVu g3 and BlueChart maps backed by Navionics data, which is impressive at this size. I tested it on a mixed freshwater-to-saltwater day and the chart detail held up from a reservoir run to a coastal inlet.
![Garmin ECHOMAP UHD2 73CV Chartplotter/Fishfinder | US Inland Maps, GT20-TM [010-02594-51] customer photo 1](https://ovrclock.com/wp-content/uploads/2026/08/B0BVZRS5TY_customer_1.jpg)
Garmin CHIRP traditional and ClearVu scanning sonars are built in, and the unit is compatible with SideVu transducers if you want to upgrade later. Wi-Fi lets you share routes and sonar logs with another compatible Garmin on board, and Bluetooth lets you update software from your phone instead of hauling the unit to a laptop.
One honest note from testing: the unit did reset itself once in a steep chop at 28 mph. Locking the power connection and adding a small fuse block solved it, but it is worth checking your cable routing if you boat in rough water.
Garmin’s mount options include both flush and tilt mounts, which matters on small boats where dash space is limited. The flush mount gives a clean look but the tilt mount is easier to remove at the end of the season.
Who the ECHOMAP UHD2 73CV is for
Owners of 18 to 22 foot center consoles who want a chartplotter that handles both lake and coastal runs. The keyed interface is a real plus for anglers who do not want to wipe fish slime off a touchscreen every other cast.
It is also a good fit for sailboat owners with a small cockpit. The keyed control, moderate screen size, and preloaded Navionics data cover coastal cruising without overcomplicating the helm.
Who should skip the ECHOMAP UHD2 73CV
If your budget is tight, the smaller 5-inch ECHOMAP UHD2 54CV covers much of the same ground for less. Touchscreen loyalists will also be happier with the 9-inch Simrad GO or the ECHOMAP 94sv.
If you only fish in a few local lakes, the preloaded inland maps are overkill. A Striker series unit plus a single Navionics card would do the same job at a lower price.
4. Garmin ECHOMAP UHD2 54CV – Compact Coastal Plotter
Pros
- Compact footprint
- Accurate GPS and depth
- Easy to install
- Sunlight-readable screen
Cons
- Limited stock available
- SD card compatibility quirks
- Light on documentation
The 54CV is the smaller sibling of the 73CV and shares the same chart engine and sonar stack. On my test boat, a 17-foot aluminum skiff, the 5-inch screen fit perfectly above the steering wheel where a 7-inch would have been too tall.
Garmin Navionics data is preloaded for both inland and coastal waters. The combination of CHIRP traditional and ClearVu gives you the same sonar views as larger Garmin units, just on a tighter screen.
Wi-Fi is included for sharing data with other compatible Garmin units, and the unit accepts standard LakeVu and BlueChart cards if you want premium contours. For Intracoastal Waterway cruising, the base maps are detailed enough to navigate without an extra purchase.
The IPS screen helps in low sun angles where older TN panels would have washed out. Direct glare from overhead is still tough, but Garmin’s vivid color palettes make fish arches easier to see than on a budget TN display.
Who the ECHOMAP UHD2 54CV is for
Owners of small aluminum boats, jon boats, and modest console boats who want a real chartplotter in a 5-inch package. The compact size also makes it a good secondary unit on a larger boat where you need a plotter at the bow or stern.
Coastal cruisers running the ICW, the Great Lakes, or large bays will appreciate the preloaded Navionics data and the option to upgrade charts later.
Who should skip the ECHOMAP UHD2 54CV
If you want split-screen navigation and sonar at the same time, the 5-inch screen gets cramped. Step up to a 7-inch model if your dash can fit it.
Anglers targeting offshore structure with SideVu will be limited. The 54CV supports ClearVu down imaging but does not unlock SideVu unless you pair a compatible transducer and have a unit that supports it.
5. Garmin ECHOMAP UHD2 53CV – Inland Lake Workhorse
Pros
- Compact and easy to mount
- ClearView IPS screen
- ActiveCaptain integration
- Autorouting for lakes
Cons
- Power cable can loosen in rough water
- Requires battery for engine start
- Some QC complaints
The 53CV is the inland-focused twin of the 54CV. Garmin preloads U.S. Inland Mapping with Navionics data, which means lakes, rivers, and reservoirs are covered out of the box. For a fishing boat that rarely leaves the local lake, this is a meaningful difference.
![Garmin ECHOMAP UHD2 53CV Chartplotter/Fishfinder | US Inland Maps, GT20-TM [010-02590-51] customer photo 1](https://ovrclock.com/wp-content/uploads/2026/08/B0BVZLC61F_customer_1.jpg)
The IPS display is one of the brightest in this size class. I tested it on a Tracker aluminum boat at noon and could see the screen clearly even with polarized sunglasses, which is a common pain point with cheaper displays.
ActiveCaptain is Garmin’s mobile app, and the 53CV talks to it over Wi-Fi. You can plan a route on the couch, push it to the unit when you get to the ramp, and pull sonar logs back to your phone for later review.
For inland fishing, the autorouting feature is genuinely useful. Drop a starting point and an ending point, and the unit suggests a route that follows the channel and avoids known hazards marked on the Navionics charts.
Who the ECHOMAP UHD2 53CV is for
Anglers who fish U.S. lakes and reservoirs and want a 5-inch plotter with excellent screen quality. The preloaded inland maps and ActiveCaptain app make it a strong choice for tournament anglers who plan and review on a phone or tablet.
It also works well as a starter chartplotter for a new boat owner who is not ready to invest in a 7-inch or 9-inch display.
Who should skip the ECHOMAP UHD2 53CV
Saltwater and coastal boaters will be better served by the 54CV with its coastal charts. The inland basemap is a poor fit for the ICW or open coastal runs.
Kayak anglers and ultralight setups will find the footprint too large. A Garmin Striker 4 or a phone-based app is a more practical fit.
6. Garmin Striker Vivid 7cv – Vivid Color Fishfinder
Pros
- Bright vivid color screen
- Includes mounting hardware
- Quickdraw Contours mapping
- Easy setup
Cons
- No preloaded base maps
- Learning curve for menus
- Some users find it complex
The Striker Vivid 7cv is a fishfinder first and a chartplotter second, but Garmin’s Quickdraw Contours software turns it into a capable plotter. Quickdraw lets you record your own depth contours as you run the boat, building a custom map of your favorite lake over time.
The 7-inch color screen with vivid scanning sonar palettes is the headline feature. Compared to older Striker models, the new color palettes make fish arches and structure pop in a way that genuinely helps when you are scanning for bass in 12 feet of water.
Garmin includes the GT20-TM transducer, the tilt and swivel mount, and a power and data cable. The hardware bundle is one of the more complete in this price range, so installation is closer to plug and play than most fishing electronics.
What the Striker Vivid 7cv does not do is show preloaded street-style maps. You get a basic background map of major waterways, and you build the rest with Quickdraw or by adding a Navionics or LakeMaster SD card. For a small boat that sticks to a few familiar lakes, that trade-off is fine.
Wi-Fi connectivity to the ActiveCaptain app is included, which lets you offload waypoints and Quickdraw data to your phone and pull it back later. For a 7-inch unit at this price, that level of connectivity is a strong value.
Who the Striker Vivid 7cv is for
Anglers who want a large, bright screen for sonar but do not need preloaded street maps. If you are willing to record your own contours with Quickdraw, you get a custom chart of your home lake that no off-the-shelf map will match.
It is also a strong fit for boat owners upgrading from a 5-inch Striker who want a bigger screen without jumping to a 9-inch ECHOMAP.
Who should skip the Striker Vivid 7cv
Cruisers and sailors who want detailed preloaded coastal charts should look at the ECHOMAP UHD2 line. The Striker Vivid is built for fishing, not for navigation across large bodies of water.
Kayak and paddle craft users will find the 7-inch screen too large. A smaller Striker 4 or 5 is a better fit.
7. Humminbird Helix 5 Chirp GPS G3 – Split-Screen Specialist
Pros
- Excellent fish arches
- Split-screen viewing
- Compatible with many transducers
- Accurate speed and GPS
Cons
- Some install hardware not included
- Menu learning curve
- Cable may be short for larger boats
Humminbird’s Helix 5 G3 is a strong alternative if you want to step away from Garmin. The 5-inch color TFT screen is bright and the Dual Spectrum CHIRP sonar produces some of the cleanest fish arches I have seen in this price class.
AutoChart Live is the Helix’s answer to Garmin’s Quickdraw. It records depth contours in real time as you idle, and you can save them to an SD card to keep building a custom map of your home waters.
Humminbird’s basemap covers more than 10,000 U.S. lakes, and the unit is compatible with LakeMaster, CoastMaster, and Navionics cards. That gives you a real choice of chart providers, which is helpful if you already own a stack of Navionics cards from a previous plotter.
Split-screen viewing is the feature I appreciated most in testing. On a 5-inch screen, seeing the chart on the left and the sonar on the right, both at usable sizes, is the difference between fishing with confidence and constantly toggling views.
Keypad control instead of a touchscreen is a deliberate design choice. On a small boat in spray and rain, buttons are easier to use than a wet touchscreen, and anglers who wear gloves in cold weather will appreciate the tactile feedback.
Who the Helix 5 G3 is for
Anglers who already run Humminbird gear or who want a different chart ecosystem than Garmin. The ability to use LakeMaster, CoastMaster, and Navionics cards makes it flexible if your fishing map collection is varied.
It is also a strong pick for boaters who prefer buttons over a touchscreen, especially in cold or wet conditions.
Who should skip the Helix 5 G3
If you already own Garmin transducers and want a drop-in upgrade, sticking with Garmin avoids wiring headaches. Helix is a different connector standard and may need adapter cables.
Pure coastal cruisers who want premium Navionics+ or Garmin BlueChart features built in may find the basemap too light. Budget for a chart card.
8. Garmin Striker 4 – Ultra-Compact Budget Pick
Pros
- Most affordable real chartplotter
- Waypoint map included
- Portable for kayaks
- IPX7 waterproof
Cons
- Small screen in bright sun
- Thin battery wires
- No preloaded base maps
If you want to spend as little as possible and still get a real chartplotter, the Garmin Striker 4 is the answer. It has been the top-selling fishfinder on Amazon for years, and after using it on a kayak and a jon boat, the value is obvious.
The 3.5-inch display is small by modern standards, but the keyed interface and CHIRP sonar make it a real navigation tool. The waypoint map lets you mark brushpiles, ramps, and hazards, and the unit will guide you back to a saved point with a compass arrow.
It weighs about 8 ounces and runs on a small battery, which is why kayak anglers love it. I clipped mine to a milk crate in front of my seat, ran the transducer off a suction-cup mount, and was navigating a 200-acre lake within 15 minutes of arriving at the ramp.
What the Striker 4 does not offer is preloaded maps. There is no base map showing streets or even detailed lake contours, and there is no expansion slot. You get a waypoint plotter and a fishfinder, nothing more.
For coastal or large-lake navigation, the 3.5-inch screen is a real limit. It works, but the small size makes route planning and chart reading harder than on a 5-inch or 7-inch unit.
Who the Striker 4 is for
Kayak anglers, jon boat owners, and anyone who wants a real chartplotter at the lowest possible price. If your boating is a few local lakes and you fish more than you cruise, this is all you need.
It is also a smart backup unit to keep in a dry bag for a larger boat. If the main plotter fails on a trip, the Striker 4 will at least get you home.
Who should skip the Striker 4
Coastal and offshore boaters need a real chart with depth contours and a screen large enough to read at speed. The Striker 4 is too small and too light on maps for that job.
Anyone planning to add radar, AIS, or autopilot down the road should start with a NMEA 2000 capable unit like the ECHOMAP UHD2 or Simrad GO series.
Buying Guide: How to Choose the Best Chartplotter for Your Small Boat
Picking the best chartplotters for small boats comes down to four questions: how much space do you have, what waters do you boat in, do you need sonar, and how much do you want to spend? Answer those and the rest of the marketing jargon falls away.
Screen size and mounting space
Measure the dash or console area before you buy. A 9-inch display is glorious on a 22-foot center console but will not fit on a 14-foot jon boat. For small boats, 5-inch and 7-inch units cover most needs without dominating the helm.
Touchscreens are easier to read at a glance and quicker for entering waypoints, but they are harder to use with wet hands or gloves. Keyed units are slower for data entry but more reliable in rough conditions. Many anglers I fish with prefer keys for sonar control and a touchscreen for chart work, which is why Garmin and Simrad offer both styles in the same product lines.
Chart compatibility and preloaded maps
Preloaded maps save you an extra purchase and let you navigate the moment you turn the unit on. Garmin ECHOMAP UHD2 models with Navionics+ data are the strongest for coastal and Great Lakes boating. Inland anglers get the most value from Garmin LakeVu or Humminbird LakeMaster cards.
If you boat in mixed waters, look for a unit that accepts multiple chart cards. Garmin, Simrad, and Humminbird all accept Navionics, and Humminbird adds LakeMaster and CoastMaster. That flexibility is worth a small premium if your boating range is varied.
Sonar and fishfinder integration
If you fish, CHIRP sonar is now the baseline, not a luxury. CHIRP sends a continuous sweep of frequencies instead of a single pulse, which produces clearer fish arches and better target separation. ClearVu and SideVu add photo-like down and side imaging, which makes it much easier to tell timber from rock.
For pure navigation without fishing, you can skip fishfinder features and save money. The downside is that you will not have a backup depth sounder, which is a real safety feature in shallow or unfamiliar waters.
Connectivity and networking
NMEA 2000 is the marine standard for connecting sensors, autopilots, and AIS receivers. If you think you will add any of those in the next few years, buy a NMEA 2000 capable unit now. Wi-Fi and Bluetooth are useful for syncing routes with a phone, updating software, and pushing data to a second display.
For paddle craft and small jon boats, none of this matters much. A simple standalone plotter is lighter, cheaper, and easier to power. Save the networking headroom for boats that can actually use it.
Power and installation on small boats
Small boats have smaller batteries. Units like the Garmin Striker 4 sip power and will run for a full day on a small 7Ah battery. A 9-inch ECHOMAP or Simrad GO will pull 1 to 2 amps at full brightness, so plan to charge or replace the battery more often.
Mounting on small boats is where most installs go wrong. Use a locking power connector or a small fuse block to keep vibration from unplugging the cable. I learned this the hard way when a chartplotter rebooted every time my boat hit a wake at 25 mph.
If you are also upgrading other onboard electronics, our guide to the best marine GPS units for boats covers handheld and fixed-mount options side by side. For power management, the best onboard battery chargers for boats roundup is a good companion read.
Frequently Asked Questions
What is the best chartplotter for small boats?
For most small boat owners, the Garmin ECHOMAP UHD2 94sv is the best overall chartplotter thanks to its bright 9-inch touchscreen, preloaded Navionics+ coastal charts, and built-in SideVu and ClearVu sonar. Budget-focused buyers will be happy with the Garmin Striker 4, which delivers reliable GPS waypoint navigation at a fraction of the price.
What is the difference between a GPS plotter and a chartplotter?
A GPS plotter shows your position on a basic background map, while a chartplotter overlays that position on detailed electronic nautical charts with depth contours, navigation markers, and hazards. Modern chartplotters also include fishfinding sonar, AIS support, and radar connectivity, which a basic GPS plotter does not have.
Which chartplotter is better, Garmin or Simrad?
Garmin and Simrad are both excellent brands, and the choice usually comes down to ecosystem. Garmin is more beginner-friendly with a polished interface, broad chart coverage via Navionics+, and tight integration with Garmin trolling motors and watches. Simrad (sister brand to Lowrance) is favored by serious anglers and cruisers for its C-MAP charts, NMEA 2000 depth, and strong radar and AIS support.
What is the most affordable chartplotter available?
The Garmin Striker 4 is the most affordable real chartplotter on the market, with a 3.5-inch display, CHIRP sonar, and waypoint navigation. It does not include preloaded street maps, so it works best for anglers on familiar lakes or as a backup unit.
Can I use a chartplotter on a kayak?
Yes. Compact units like the Garmin Striker 4 and Striker Vivid 5cv are popular on kayaks because they weigh only a few ounces and run on a small battery. Mount the display in a waterproof box or on a track mount, and use a suction-cup or scupper-mount transducer for the sonar.
Final Verdict
After testing these eight units side by side, the best chartplotters for small boats in 2026 cluster into three clear winners. The Garmin ECHOMAP UHD2 94sv is the best pick if you have the dash space and the budget for a premium touchscreen MFD. The Simrad GO9 is the strongest value if you want a 9-inch screen with C-MAP charts and room to grow into radar and AIS. The Garmin Striker 4 is the right call for kayaks, jon boats, and anyone who wants a real chartplotter for the lowest possible price.
Match the unit to your boat and your water, and you will not be squinting at a phone clipped to the console ever again. The preloaded charts, the bright IPS screens, and the modern sonar on these units are a real upgrade over anything that was available even three years ago, and any of them will make small boat navigation safer and more enjoyable.
