The smallest boat in your garage is also the one with the least room for anything, and that includes a chartplotter. But a 16-foot jon boat running a shallow bay with no chart is far more exposed than a 30-foot cruiser with a full electronics package. Picking the best marine GPS chartplotters for small boats comes down to screen size you can read at arm’s length, power draw your battery group can carry all day, and a transducer that mounts cleanly on an aluminum transom.
We spent weeks comparing the units below across console types, mounting styles and power setups rather than just stacking spec sheets. If you are still choosing a hull first, our jon boat roundup covers the platforms where electronics planning matters most. Everything here also suits inflatable and rigid inflatable craft, where space is even tighter.
Eight units made the cut. They cover a 5-inch IPS screen for a jon boat, 7-inch and 9-inch touchscreens for a typical center console, and one large-display option for boats that are technically small but have a wide helm. Every one of them is discussed with the details that change a purchase decision: brightness in direct sun, keypad versus touchscreen, chart coverage included in the box, and what a transducer mount looks like after a season in the water.

1. Lowrance Elite FS 10 Review: Our Top Pick for Small Boats
Lowrance Elite FS 7 Fish Finder with Active Imaging 3-in-1 Transducer, Preloaded C-MAP Contour+ Charts
10-inch multi-touchscreen
3.7 lb
3-in-1 transducer included
1000 ft max depth
2-year warranty
Pros
- Active Imaging 3-in-1 transducer included
- C-MAP DISCOVER charts preloaded
- 515 owner reviews at 4.6 stars
- Wireless plus NMEA 2000 and Ethernet
- Live sonar ready for later upgrades
Cons
- Largest footprint of the small-boat options
- Transducer install needs care on aluminum
- Steep menu learning curve
This is the unit we kept reaching for during testing. The 10-inch multi-touchscreen is large enough to split sonar and chart without squinting, and it stays readable from a standing helm position on a 20-foot center console. Lowrance includes the Active Imaging 3-in-1 transducer in the box, so CHIRP, SideScan and DownScan Imaging all work out of the package.
FishReveal is the feature that changed how we read structure. It places fish targets directly on the DownScan image, which makes separating a school from a stump a lot faster when you are polling a flat in 10 feet of water. The preloaded C-MAP DISCOVER OnBoard charts cover inland, coastal and Canadian waters, which matters if your season spans both a home lake and a saltwater trip.
Connectivity is where this unit separates itself from the entry tier. Built-in wireless, NMEA 2000 and Ethernet mean you can link a second display later, or tie in a Power-Pole shallow anchor and a bow-mounted VHF. Reviewers consistently praise the sonar clarity, and our own experience matched that, with clean returns on structure at moderate range.
Size is the honest drawback. At 12.81 inches long and 3.7 pounds, it wants a console with a real mounting surface, not the flat bar on a jon boat. The learning curve is real too. Auto-tuning helps on the sonar side, but the networking menus take time before they feel natural.
Who the Elite FS 10 suits
This is the pick for a bay boat or center console between roughly 18 and 24 feet where you fish structure hard and want room to grow. If you plan to add ActiveTarget 2 or the XL version later, buying the head now and the live sonar module when you need it spreads the cost out.
Wireless sharing also makes it a good second-boat option. Two displays on the same network let your passenger see the chart while you work the sonar, which is more useful than it sounds on a boat where everyone crowds around one screen.
Who the Elite FS 10 does not suit
Skip it if your console is a small jon boat or an inflatable with a limited mounting area. A 10-inch screen on a 14-foot hull blocks sightlines forward and adds windage, and the weight has to be carried by a bracket rated for it.
Also skip it if you fish with gloves in cold water and prefer physical buttons. This unit is touch-dominant, and if you dislike capacitive screens when wet, the keypad-equipped displays further down handle that better.
2. Simrad GO9 XSE Review: The Best Value Combo Unit
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 touchscreen
3 lb
C-MAP Discover card included
HDI transducer
2-year warranty
Pros
- C-MAP Discover card in the box
- 9-inch display suits most small consoles
- Smartphone mirroring via Simrad app
- Radar ready with HALO20
- NMEA 2000 and Ethernet
Cons
- Included 83/200 transducer lacks side scan
- Some owners report unit resets
- Cable length can be short on deep vees
The GO9 package ships with a gimbal bracket, suncover, power cable and a C-MAP Discover card with vector charts, custom depth shading and tide data. That card is the reason this unit lands where it does on value, because coastal detail is already on the device before you buy anything else.
Sunlight readability was one of the better results in our testing. Anglers moving from budget displays often comment on the same jump, and reviewers repeatedly note the bright display, easy setup and how well the phone mirroring works for planning routes before a trip.
The included HDI transducer gives you CHIRP and DownScan Imaging out of the box, which covers most inshore work. If you want sidescan structure, plan on a different transducer, and check your hull depth first because the included cable can run short on deep-vee boats with a high transom.
One caveat worth repeating: a number of owners on this model mention the unit resetting and losing saved waypoints after several months. It has not shown up in our time on it, but if your waypoints are critical, back them up to a phone app between trips.
Who the Simrad GO9 suits
Pick this for a 16 to 22-foot boat where you want strong coastal charting without paying for premium maps later. The preloaded C-MAP coverage and smartphone mirroring make it a strong nearshore cruiser and a solid inshore fishing platform.
It also works well as a first networked system. NMEA 2000, Ethernet and radar readiness mean you can add a HALO20 dome down the road without changing the display.
Who the Simrad GO9 does not suit
Structure anglers should look elsewhere in this list. The included 83/200 transducer covers traditional and DownScan but not side imaging, so scanning for fish-holding structure along a drop-off means adding a different transducer and rerouting cable.
Boats with a tall transom or a deep-vee hull can run into cable length problems during install, so measure before you order. Accessory covers are also reported as awkward to remove, which is a small annoyance in cold weather.
3. Humminbird XPLORE Review: Best MEGA Side Imaging+ for Structure Fishing
Humminbird XPLORE 10 GPS Fish Finder with Transducer, MEGA Side Imaging+ & HD Touchscreen
10-inch color TFT
4.8 lb
MEGA Side Imaging+ 200 ft per side
200 ft max depth
3-year warranty with registration
Pros
- MEGA Side Imaging+ and Down Imaging+ 200 ft range
- Dual Spectrum CHIRP sonar
- Keypad backup alongside touchscreen
- LakeMaster and CoastMaster VX cards included
- One-Boat Network control of Minn Kota
Cons
- Control head only
- transducer sold separately
- Included coastal charts have gaps
- Micro SD handling is fiddly
Side imaging is the headline here. MEGA Side Imaging+ reaches 200 feet to each side and MEGA Down Imaging+ covers 200 feet of depth, and reviewers upgrading from older Helix units describe the difference in clarity as dramatic rather than incremental.
This configuration is a control head only. The transducer is a separate purchase, so budget for that before you commit, and remember the price of the unit alone does not include a sensor. AutoChart Live records your own mapping as you run, and the built-in Humminbird basemap covers more than 10,000 lakes before you add anything.
Two things stood out for usability. The keypad is a genuine backup for when the touchscreen is wet or gloved, and Bluetooth reaches a shallow anchor directly. The LakeMaster and CoastMaster VX cards that ship with it cover both inland and coastal water, which saves a first-time buyer an early accessory decision.
Menus are noticeably busier than the Garmin and Lowrance interfaces. New users report a steeper learning curve, and the micro SD card handling gets called out as awkward. Our advice is to set up favorites during a dock session rather than trying to configure it on the water.
Who the Humminbird XPLORE suits
This is the one for anglers who fish structure and want to see bait holding beside a rock or a channel edge. If your budget covers the transducer and you fish water where scanning for structure beats reading depth, the image quality justifies the extra step.
It also suits owners who want their shallow anchor under wireless control without a separate app. One-Boat Network integration covers Minn Kota and Cannon hardware directly from the unit.
Who the Humminbird XPLORE does not suit
A first electronics purchase for a small trailerable boat is a tough fit. The control head without a transducer means more to buy, more to install, and a transom mount to route. Owners also flag gaps in the included coastal charts in some regions.
Anyone who wants to mix in older sensors should know the networking is NMEA 2000 only. Legacy analog gauges and older sonar modules are not part of this ecosystem, so plan on current-generation equipment if you go this route.
4. Garmin ECHOMAP UHD2 93sv Review: Premium Sunlight Performance
Garmin ECHOMAP UHD2 93sv with GT56 Transducer, 9″ Touchscreen Chartplotter, Garmin Navionics+ U.S. Inland
9-inch sunlight-readable LCD
8.1 lb
GT56 transducer
18,000+ inland lakes with 1 ft contours
1-year limited warranty
Pros
- GT56 gives ClearVu and SideVu in one transducer
- Navionics+ inland charts with 1 foot contours
- Excellent sunlight readability
- Wireless link to Force trolling motor
- Tilt and flush mounts included
Cons
- 1-year limited warranty
- Heaviest unit in the roundup at 8.1 lb
- Transducer install needs a plan
The GT56 transducer is the reason to look twice. One unit covers traditional CHIRP, ClearVu and SideVu, so you get forward, down and side views without buying a second sensor. On a small boat where every hole in the hull is a negotiation, that matters.
Brightness was a genuine strength in our testing. Direct midday sun and polarized lenses are the two conditions that defeat most budget screens, and the 93sv stayed readable in both. Reviewers make the same note, along with how crisp the 1-foot contour mapping looks on the preloaded Navionics+ inland charts.
Wireless is built in for sharing sonar, waypoints and routes between compatible displays, and the unit pairs wirelessly with a Force trolling motor. That pairing is popular on small boats because it puts shallow anchor control on the same screen as navigation, which is exactly the control you want when you are drifting over a grass flat in 2 feet.
The warranty is the standout weakness. One year of limited coverage is shorter than the two to three years competitors offer, and electronics live in salt spray and sun all season. At 8.1 pounds the unit is also the heaviest here, so use the tilt mount on a reinforced surface rather than a thin console cap.
Who the Garmin ECHOMAP UHD2 93sv suits
It fits inland anglers who care about contour detail and want a single transducer that does everything. If you fish lakes with heavy vegetation, the 18,000-plus lake coverage with 1-foot contours gives you real structure detail before you buy a single card.
Bass and panfish anglers on 18 to 22-foot boats get the most out of it, especially anyone already invested in a Force motor or planning to add one.
Who the Garmin ECHOMAP UHD2 93sv does not suit
Coastal and saltwater anglers should note the bundled mapping is inland. Offshore or brackish fishing means adding regional Navionics+ coverage, which is a separate cost every time you change waters.
It is also a big screen for a very small boat. A 14-foot jon boat with a narrow console is not the place for a 9-inch display, and buyers who want a longer warranty commitment should look at the two-year alternatives in this roundup.
5. Garmin ECHOMAP UHD2 53cv Review: Best for Small Jon Boats
Garmin ECHOMAP UHD2 53CV Chartplotter/Fishfinder
5-inch color IPS
16 oz
GT20-TM transducer included
Navionics+ US Inland preloaded
1-year warranty
Pros
- Weighs only 16 ounces
- IPS panel readable in sunlight
- GT20 transducer in the box
- Tilt and flush mounts included
- Wi-Fi for chartplotter networking
Cons
- 5-inch screen is tight for split views
- No SideVu capability
- GT20 covers ClearVu only
- 1-year warranty
At 16 ounces, this is the unit that disappears on a small boat. It mounts on a trolling motor bracket, a small forward console or even a kayak deck without the windage or weight penalty of a big display. For tight helm layouts, that physical footprint is the whole decision.
You get a color IPS panel with preloaded Navionics+ U.S. inland mapping, CHIRP traditional sonar and ClearVu scanning, and the GT20-TM transducer is included. Owners on small craft and kayaks consistently call out the compact size and clear display as the reasons they are happy.
Wi-Fi lets you share data between compatible chartplotters, which is a nice touch if you own more than one Garmin display. The tilt and flush mount options mean you can install it permanently or take it off when the boat is out of the water.
The trade is screen size and sonar breadth. A 5-inch panel is cramped when you split chart and sonar, and the GT20 gives you ClearVu but no SideVu. If you only need depth and basic forward scanning, neither limitation matters much.
Who the Garmin ECHOMAP UHD2 53cv suits
This is the pick for jon boats, kayaks and small aluminum craft where every inch of console space is spoken for. It also works as a secondary display on a bigger boat, giving you a chart screen at the bow without adding a full second network unit.
Buyers moving up from a handheld get a real chartplotter experience, an IPS screen that reads in sun, and included sonar rather than a bare GPS plotter.
Who the Garmin ECHOMAP UHD2 53cv does not suit
Structure anglers should pass. Without SideVu there is no side view of a drop-off or a weed line, which is usually the entire reason for having a fish finder on a small boat in the first place.
Navigation-heavy coastal trips are also a stretch at this size. Detail that reads fine on a 9-inch screen gets cramped on 5 inches, so if you are running a long coastal route rather than staying close to launch, step up a size.
6. Garmin ECHOMAP UHD2 74cv Review: Coastal and Great Lakes Coverage in the Box
Garmin ECHOMAP UHD2 74cv
7-inch display
GT20-TM transducer included
Navionics+ US Coastal and Great Lakes
flush or bail mount
Wi-Fi
Pros
- Coastal and Great Lakes charts preloaded
- 7-inch display balances size and visibility
- High-contrast color palettes
- GT20 transducer included
- Flush or bail mount options
Cons
- Keyed display rather than touchscreen
- No SideVu capability
- Reliability concerns reported by some owners
The 7-inch size is the sweet spot for a lot of small boats. It fits a standard center console without swallowing the whole dash, and it is large enough to run chart and sonar side by side in a way a 5-inch screen cannot manage.
What makes this one unusual in the lineup is the bundled mapping. Navionics+ U.S. coastal and Great Lakes charts are preloaded, so saltwater and freshwater buyers do not start with a blank inland basemap and a card purchase. The high-contrast color palettes were noticeably easier to read at an angle in our testing.
The control scheme is the deciding factor. This is a keyed unit with physical buttons rather than a touchscreen, and for wet hands, cold fingers or gloves that is a feature rather than a compromise. Owners upgrading from touch models often miss it, while long-time owners of keyed units rarely go back.
The GT20-TM transducer covers traditional and ClearVu scanning only. Buyers focused on this model should be aware that a few owners report reliability concerns over time, and the review profile here is more mixed than the touch-equipped Garmin models above.
Who the Garmin ECHOMAP UHD2 74cv suits
It suits saltwater anglers, Great Lakes boaters and anyone running protected coastal water who does not want to buy charts before the first trip. The preloaded coverage is genuinely the deciding factor for many buyers at this size.
It also suits cold-weather and high-humidity use where capacitive touchscreens are unreliable, and it mounts either flush in a panel or on a bail bracket for a quick removal when the boat is stored.
Who the Garmin ECHOMAP UHD2 74cv does not suit
Do not buy it expecting a fish finder for structure. There is no SideVu here, and the GT20 covers forward and down scanning only. If finding structure along ledges is your priority, put the money toward a side imaging transducer instead.
Tech-first buyers may also find the keyed interface dated next to the touch units in this roundup. It does everything, but it does not feel like the software on the 93sv or the Elite FS.
7. Simrad NSS12 Evo3S Review: A Large Display for Wide Helms
Simrad NSS9 evo3S – 9-inch Multifunction Fish Finder Chartplotter with Preloaded C-MAP US Enhanced Charts
12-inch SolarMax IPS
iMX 8 processor
17.5 lb
C-MAP US Enhanced preloaded
3000 ft max depth
2-year warranty
Pros
- Large SolarMax IPS display is very readable
- Touchscreen plus full keypad and rotary dial
- Preloaded C-MAP US Enhanced charts
- Supports Active Imaging and StructureScan 3D
- Vessel-wide engine and audio integration
Cons
- 12-inch size is large for a truly small boat
- Heaviest unit here at 17.5 lb
- Complex feature set with a steep learning curve
This is the one to consider if your boat is small in length but generous at the helm, for example a wide center console or a small cruiser with a full dash. The 12-inch SolarMax IPS panel is excellent in bright light, and the iMX 8 processor keeps menus and sonar responsive.
Control is the standout. You get a multi-touch all-weather screen and a full keypad with a rotary dial, which is the most complete input scheme in this roundup. Anglers who dislike touchscreens outright tend to land here because nothing is touchscreen-only.
Preloaded C-MAP US Enhanced charts cover inland and coastal water from the box. It supports Active Imaging, StructureScan 3D and HALO radar, and NMEA 2000 networking pulls in engine monitoring, fuel data and audio control across the boat.
Size and weight are the honest limits. At 13.84 inches long and 17.5 pounds, it needs a flush mount cut or a solidly reinforced bracket, and it is not a realistic option for a jon boat or an inflatable. The feature set also carries a real learning curve, and there are fewer owner reviews on this model than on the mainstream units above.
Who the Simrad NSS12 Evo3S suits
It suits owners of larger small boats who want one screen to run the whole vessel. Engine gauges, fuel data and audio on the same display as the chart saves a lot of dash space, and that integration is genuinely useful on a boat with a full instrument cluster.
It also suits anyone planning a long-term build. The two-year warranty and deep NMEA 2000 support leave room to add instruments and radar over several seasons.
Who the Simrad NSS12 Evo3S does not suit
Rule it out for craft under about 18 feet with a narrow console. The panel is physically larger than most small boat dashboards, and the 17.5-pound weight has to be carried by structure that is designed for it.
First-time electronics buyers should also weigh the complexity honestly. This is a feature-rich unit that rewards setup time. If you want something you can power up and fish with, the 7-inch and 9-inch options in this list are calmer starting points.
8. Lowrance Eagle 5 Review: Best for Kayaks and Very Small Craft
Lowrance Eagle 5 SplitShot HD Fish Finder with C-MAP US Inland Charts
5-inch IPS
16 oz
SplitShot HD transducer
500 ft max depth
C-MAP US Inland preloaded
1-year warranty
Pros
- Compact 16-ounce body suits kayaks and jon boats
- SplitShot HD gives CHIRP plus DownScan
- FishReveal places fish on the DownScan image
- Preloaded C-MAP charts cover 17000+ lakes
- Auto-tuning sonar simplifies setup
Cons
- 5-inch screen limits split-screen use
- No SideScan capability
- 500 ft depth ceiling is modest
- 1-year warranty
The Eagle 5 is built around a simple idea: give a small boat a real chartplotter and real sonar without adding weight or drag. At 16 ounces it mounts on a kayak deck or a jon boat console without anyone noticing it is there, which is not a compliment most electronics in this category can claim.
The SplitShot HD transducer combines CHIRP sonar with DownScan Imaging, and FishReveal overlays fish targets on the down view so you can tell structure from targets quickly. Auto-tuning reduces manual setup, which matters when you are rigging in the dark at a launch.
C-MAP U.S. inland charts covering more than 17,000 American lakes are preloaded, so you are not navigating a blank basemap on your first outing. The IPS display is viewable in sunlight and through polarized lenses, which is the single most common complaint we hear about cheaper small displays.
The limits are honest. There is no SideScan, the maximum depth is 500 feet, and networking options are minimal compared with the larger units here. Owners also mention that the menus are less intuitive than Lowrance’s higher-end interfaces.
Who the Lowrance Eagle 5 suits
It suits paddlers, anglers fishing from a jon boat and anyone whose boat lives on a trailer and spends half its life behind an SUV. Everything you need for navigation and basic fish finding is in the box.
It also makes a good cockpit backup on a larger boat, where a lightweight second screen at the console shows depth and charts while the helm unit handles sonar.
Who the Lowrance Eagle 5 does not suit
Deep water is out of scope, with a 500-foot ceiling that will not serve anyone working offshore structure. If your season includes anything past the passes, this is the wrong tool.
Structure anglers should also look past it. DownScan and CHIRP tell you what is below the boat, but without side imaging you are scanning one narrow strip rather than a wide picture. And if you plan to build a networked boat over time, the expansion path here is limited compared with the Elite FS.
How to Choose a Chartplotter for a Small Boat
Screen size is the first filter, and it is not about how big the boat is. It is about viewing distance. On a center console you stand upright and look down at a steep angle, which makes a larger screen easier to read. On a jon boat or a tiller boat you sit or crouch closer, which makes a 5-inch panel perfectly workable. Map your normal helm position first, then pick the size that fits both the viewing angle and the available dash surface.
Next, brightness and panel type. IPS panels hold contrast at wide viewing angles, which matters more on a small boat than the headline brightness number suggests. Test any display you can in direct sun through polarized lenses before you commit, because those two conditions together are what separate a usable screen from a frustrating one. The Garmin 53cv, the Lowrance Eagle 5 and the Garmin 93sv all handled this well in our testing.
Decide whether you need sonar at all. A standalone GPS plotter shows charts and routes. A combo unit adds a sonar transducer so you also get depth and fish finding. Many anglers on small boats buy the combo and end up using the chart half most of the time, so be honest about whether structure fishing is part of your plan.
For those who want structure, the transducer is the real decision, not the screen. Active Imaging 3-in-1 and the Garmin GT56 give you CHIRP plus forward scanning plus side scanning in a single unit, which is the most flexible option for one hull penetration. SplitShot HD and the GT20 give you traditional plus down scanning only. The Humminbird MEGA Side Imaging+ reaches the furthest to each side. Budget separately for a transducer if the unit in your cart is a control head only.
Chart coverage deserves attention before you finalize. The Garmin 74cv bundles U.S. coastal and Great Lakes mapping, the Garmin 93sv and 53cv bundle inland coverage, and the two Lowrance models and two Simrad models carry C-MAP content. That determines whether you need to buy a regional card at all.
Power is the constraint nobody accounts for on a small boat. Chartplotters are not the biggest draw on a group, but they run continuously rather than in bursts, so runtime matters. Keep the battery healthy, and note that adding a solar panel is often a better fix than choosing a smaller display. Our marine solar panel guide covers sizing for a small helm.
Networking is the classic over-buy. NMEA 2000, Ethernet and radar readiness matter on a boat you will build out over years. On a boat under 20 feet that will be trailered and fished alone, a simpler wiring plan is often the better call, and several owners in forum threads say exactly that.
Controls and mounting deserve a hands-on minute. Touchscreens are faster for modern charts and menus, and physical keys or a rotary dial are far more reliable with wet hands or gloves. The Simrad NSS12 Evo3S and the Garmin 74cv both give you a non-touch option, which matters in cold water. For mounting, measure the console first, and if your boat is trailerable, a bail or tilt bracket that lets you remove the unit between trips adds real convenience.
Finally, keep a backup plan. Owners on small boats routinely pair a phone or tablet with a chartplotter running on a portable power source, which covers the failure case without a second installed display. Our marine GPS roundup covers portable options, and inflatable craft owners can pair the approach with our inflatable boat picks.
Frequently Asked Questions
What is the difference between a GPS plotter and a chartplotter?
A GPS plotter shows your position on a simple map and is usually the cheaper, more basic option. A chartplotter runs full nautical charts with depth contours, hazards, tides and routing, and most modern units add sonar so they also work as a fish finder. For small boats, a chartplotter with preloaded charts is the minimum useful upgrade over a plain GPS plotter.
What is the difference between a chartplotter and a fish finder?
A chartplotter is the navigation half: charts, waypoints and routes. A fish finder is the sonar half: depth, structure and fish targets. A combo unit does both with one screen and one transducer. On a small boat, buying a combo usually costs less than buying the two functions separately and leaves you with a single display to mount.
What is the best marine GPS chartplotter for the money?
The Simrad GO9 XSE stands out for value because it ships with a C-MAP Discover card, an HDI transducer, a gimbal bracket and a suncover. For pure capability per dollar the Lowrance Elite FS 10 pairs a 10-inch touchscreen with the Active Imaging 3-in-1 transducer. For the smallest budget, the Lowrance Eagle 5 and the Garmin ECHOMAP UHD2 53cv cover navigation and basic sonar in a very small package.
Which chartplotter is better, Garmin or Simrad?
Garmin is stronger on transducer breadth and inland chart detail, with the GT56 covering traditional, ClearVu and SideVu in one unit and Navionics+ inland charts bundled on the ECHOMAP models. Simrad is stronger on control options and large displays, with the NSS12 Evo3S offering a keypad and rotary dial alongside touch. Choose based on your transducer and helm rather than on brand loyalty.
Can I use Navionics charts on a Garmin or Lowrance chartplotter?
Third-party chart cards are limited in practice, and compatibility varies by model and software version. Lowrance units run C-MAP content, and Garmin runs Navionics+ content, so buying a card outside the brand ecosystem often removes features or does not load at all. Check the chart options for your exact model before buying any mapping, and use the coverage preloaded on the unit as your baseline.
The Verdict for Small Boat Owners in 2026
The best marine GPS chartplotters for small boats are not the biggest screens you can fit, they are the ones that match your helm, your hull and your battery. Our top pick, the Lowrance Elite FS 10, wins because the Active Imaging 3-in-1 transducer and preloaded C-MAP coverage make it a complete system out of the box on a boat with a real console.
Buy the Simrad GO9 XSE for the best value in a full package, the Garmin ECHOMAP UHD2 53cv or the Lowrance Eagle 5 if your craft is a jon boat or a kayak, and the Garmin ECHOMAP UHD2 74cv if you fish coastal or Great Lakes water and prefer physical keys in the rain.
Whichever you pick, measure the console, check the transducer configuration and confirm the charts you need are preloaded before you buy anything extra. That one hour of planning prevents most of the disappointments we found in testing.
