8 best marine gps chartplotters for small boats (October 2026)

If you own a RIB, a jon boat, a bay boat, a bowrider, a pontoon or a center console under about 22 feet, the navigation electronics market is stacked with 12-inch helm units that were designed for something else entirely. We looked at the compact class instead: the 5-inch, 7-inch and 9-inch multi-function displays that actually mount to a small console, plus one portable kit for the boat that lives in a garage. Every pick below is a real unit we examined spec by spec, and the shortlist is deliberately narrow so the comparison is meaningful.

Our headline answer first. The Lowrance Elite FS is our Editor’s Choice, the best marine GPS chartplotter for small boats overall, because it bundles a 3-in-1 CHIRP, SideScan and DownScan transducer, comes with C-MAP DISCOVER charts already onboard, and networks properly, which is capability you normally only get on a much larger helm unit. For the many boats whose console is genuinely small, the Garmin Striker Vivid 7cv is the better physical fit, and if you are strictly budget-bound the Humminbird Helix 5 CHIRP G3 covers the essentials without a subscription argument.

One thing we will say up front, because it is what surprises small-boat owners most: the display is rarely the whole bill. A unit sold without a transducer means a second purchase, and a mount, wiring, fusing and install labour sit on top of that. We have broken that out in the total cost of ownership section near the end, and we have flagged in every review whether a transducer is in the box. If you are still working out whether you need a fixed display at all, read our handheld GPS guide first, since a portable unit solves a surprising share of small-boat navigation problems.

Top 3 Chartplotters for Small Boats in 2026

These are the three units we would put on our own boats first. The Elite FS wins on raw capability, the Striker Vivid wins on balance, and the Helix 5 wins on entry cost. Everything else in the list is a specialist worth knowing about but not our default.

All 8 Chartplotter Picks at a Glance in 2026

Here is the shortlist in one view, with what each unit gives you out of the box. Where a transducer is not included, we say so, because that is the single most expensive surprise in this category.

1. Lowrance Elite FS 10-Inch MFD Review – Full Capability on a Mid-Size Console

The Elite FS is the most capable machine on this list, and the 515 owners who have rated it broadly agree on why: you get a real 3-in-1 Active Imaging transducer in the box, so CHIRP traditional, SideScan and DownScan all arrive without a second purchase. For a small boat that means one box on the transom, one cable run, and three sonar views.

What stands out in the spec sheet is the preloaded C-MAP DISCOVER coverage. It includes inland, coastal and Canadian charts already on the unit, which removes the single most common complaint we see about entry-level chartplotters, namely that they arrive blank and expect you to buy charts. The connectivity story is also unusually complete for a boat this size: wireless, NMEA 2000 and Ethernet, so a second display or a live sonar module can be added later without starting over.

The math only works if your console can host it. This is a 10-inch multi-touchscreen unit weighing 3.7 pounds, and the listed footprint is 12.81 inches long by 8.26 inches high. On a 20-foot bay boat with a full-width console that is realistic. On a 16-foot skiff with a narrow helm, it is not, and no mount option changes that physical fact.

Sonar range is listed at 1000 feet of maximum measuring depth, which is far more than a small boat will ever need in shallow coastal water but tells you the processing is not being throttled. Owners describe the image as detailed and the screen as clear, and the consensus view is that this is a capable all-in-one rather than a unit that needs a second box to be useful.

One buyer-facing detail worth planning around: the package includes a suncover, fuse and fuse holder, a corner clip kit, a mounting bracket with knobs, and the power cable. That bracket-and-knobs arrangement is a surface mount, which is the easiest install but also the one most sensitive to console vibration on a trailered boat over a rough launch ramp.

Why the Elite FS works on a mid-size boat

Because the transducer and the charts are already in the box, the total install is closer to a single weekend than to a season of projects. The three sonar views let you fish a wreck, a shoreline and a drop-off without changing hardware. And the ActiveTarget 2 path means the live-sonar upgrade, if you ever want it, plugs into an ecosystem the unit already speaks.

When to skip the Elite FS

Skip it if your helm is under about 14 inches of usable flat surface, because a 10-inch multitouch panel in that space will fight you for glare and reach. It is also overkill for a boat that only runs on a lake, where the side-scan range will never be used. In those cases the Striker Vivid 7cv below gives you most of the practical value at a much smaller size.

2. Garmin Striker Vivid 7cv Review – The Best All-Round Small-Boat Chartplotter

This is the unit we keep coming back to, and with 574 ratings averaging 4.5 the owners are not a small sample. It is a 7-inch color fishfinder with a high-sensitivity GPS, and the GT20-TM transducer is in the box with CHIRP traditional and CHIRP ClearVu scanning sonar already configured.

For a small-boat buyer the box contents are the story: unit, transducer, power and data cable, tilt and swivel mount, hardware and documentation. That is a complete install for most hulls. The tilt and swivel bailmount means you can adjust the angle once you find the sightline from a standing position at the helm, which is a small thing that matters enormously when the sun is behind you.

The catch is maps, and it is a real one. There are no preloaded charts on this unit, so your positioning comes from the built-in GPS and from waypoints you mark yourself, with Quickdraw Contours letting you build depth contours from your own sonar history. That is genuinely useful on a lake you work, and genuinely thin on unfamiliar coastal water.

Reviewers describe consistent fish arches and dependable depth returns from kayaks, small boats and even ice shacks, which tells you the sonar quality holds up across very different hulls. The ActiveCaptain app over Wi-Fi is the bridge to phone-based chart downloads, route planning and community data, and it is why the mapping limitation is manageable rather than disqualifying.

Weight and dimensions are worth noting for the mount: 4.4 pounds, with a listed size of 11.4 by 8.9 by 8.2 inches including the transducer packaging. The bracket mount is the standard surface install, so all you need is a flat spot and a drilled pass-through for the cable.

Why the Striker Vivid 7cv fits most small boats

Seven inches is the sweet spot for a console under about 16 inches wide, and this is the one we would put on a 16-to-20-foot center console without hesitating. The included bracket gives you tilt and swivel adjustment, so you can set the glare angle from the driver’s seat rather than guessing at the dock. And the CHIRP ClearVu scanning layer finds fish and structure that a straight 2D view misses.

When to skip the Striker Vivid 7cv

Skip it if you navigate unfamiliar coastal water and do not want to depend on your phone for chart data at the helm. It is also the wrong pick for anyone whose priority is side-imaging coverage, since the ClearVu scanning view is not the same thing as SideScan. For the smallest possible footprint with charts already loaded, the ECHOMAP UHD2 53CV is the alternative.

3. Humminbird Helix 5 CHIRP G3 Review – The Budget Console Mount That Still Charts

With 488 ratings averaging 4.4, the Helix 5 CHIRP G3 is a well-established no-frills option here. It is a 5-inch color TFT with a keyed softkey interface, Dual Spectrum CHIRP sonar in Wide and Narrow modes, and a transom-mount XNT 9 HW T transducer in the box.

This is the unit to look at if your console genuinely has no room for anything larger. The listed dimensions are 4.64 by 3.3 by 7.55 inches at 2.1 pounds, and it mounts on a gimbal bracket that tilts to your sightline.

Navigation comes from the Humminbird Basemap covering more than 10000 lakes and the continental U.S. coastline, and it accepts LakeMaster, CoastMaster or Navionics cards if you want more detail later. AutoChart Live records your own sonar data in real time and converts it to contour, hardness and vegetation mapping, with eight hours of built-in recording.

Owners consistently frame it as a capable essentials-only machine: CHIRP sonar, GPS, mapping and waypoints, without the premium extras. The split-screen layout lets you watch speed and sonar together, which is the view most small-boat skippers actually use all day. Reviewers also single out the keypad as usable with wet hands or gloves, which matters more than it sounds on a wet helm in cold weather.

The recurring complaint is installation hardware. The box does not include an inline 3A fuse or additional cable length, and on a small boat with a long run from the console to the transom that becomes a second hardware errand. Plan for it before the first launch rather than after.

Why the Helix 5 is the right budget answer

It combines real CHIRP sonar with a GPS and waypoint marking, and the transducer is included, at the entry point of this list. On a 14-to-18-foot jon boat or a small pontoon where the budget is genuinely tight, this delivers the three things that matter: depth, fish arches and a mark for the spot worth coming back to.

When to skip the Helix 5

Skip it if you run a lot of water you have never fished, because the bundled basemap is general rather than navigational-grade charting. A 5-inch screen also makes true split-screen chart and sonar work cramped. And if your boat has a modern NMEA 2000 backbone already, the physical keypad and the absence of network ports make this a standalone island rather than part of a system.

4. Simrad GO9 Review – The Networking and Radar-Ready 9-Inch

The Simrad GO9 is the pick if you want a small boat to be part of a networked system rather than a standalone box. It has built-in GPS, Wi-Fi, Bluetooth, Ethernet and NMEA 2000, which is the most complete connectivity list of any 9-inch unit here, and it is radar-ready through optional HALO dome or open-array hardware.

Out of the box you get a 9-inch MFD, the transducer, a suncover, a preloaded C-MAP DISCOVER card, a gimbal bracket with knobs, and the power cable. The C-MAP card carries vector charts, depth shading, tides and currents, and bathymetric contours, so the charting story is strong out of the gate rather than something you add later.

Sonar comes from an included 83/200 kHz HDI transducer that provides CHIRP and DownScan Imaging. That is a solid freshwater and inshore package, but it is not side-imaging, and if scanning structure is your priority you will want a 3-in-1 transducer or a HALO radar package alongside it. Worth knowing before you buy, not after.

The 148 ratings average 4.4, and the owner commentary is consistent: bright screen, straightforward interface, and a sense that this is a cost-effective entry into a networked MFD. Simrad and Navico support is frequently praised for patient setup guidance, which matters if you are wiring a NMEA 2000 backbone yourself for the first time.

Two practical notes from owners. The included transducer cable can be too short to reach the display in certain hulls, so measure your run before ordering. And a handful of reviewers report GPS or waypoint loss after several months of use, so back up your waypoints to a computer or phone if you have built up a valuable library.

Why the GO9 suits a growth path

At 3 pounds with a 10.35 by 3.54 by 7.24 inch footprint, the GO9 is lighter and narrower than the Elite FS while still giving you a 9-inch screen. The Ethernet and NMEA 2000 ports mean you can add a second display, a radar dome or an autopilot later, and screen mirroring means you can push the chart to a phone when you are walking around the boat.

When to skip the GO9

Skip it if side-imaging sonar is non-negotiable, because the bundled HDI transducer will not give it to you. Also skip it if the shortest cable run from your transom to the console is tight, since the included cable is the most common install complaint. For pure side-scan value with no networking ambitions, the Helix 7 G4 covers more water per dollar.

5. Humminbird Helix 7 G4 Review – Wide Sonar Coverage and Side Imaging

The Helix 7 G4 is the sonar specialist of this list. It includes an XNT 9 HW MSI 150 T transom-mount transducer and delivers MEGA Side Imaging and MEGA Down Imaging, with listed coverage of 125 feet to each side and 125 feet below. On a small boat, that is a genuinely wide view of what is around you for relatively little money.

The build is straightforward: a 7-inch color TFT control head, power cable, the transducer, mounting hardware and a gimbal mounting bracket. It also supports in-dash mounting, which is the option to think about on a boat where the console face has a molded recess and a surface bracket would sit too proud.

Humminbird Basemap covers more than 10000 lakes and the continental U.S. coastline, and the unit accepts LakeMaster, CoastMaster or Navionics cards when you want more. AutoChart Live records your own data and converts it into contour, hardness and vegetation mapping, with eight hours of recording built in. Dual Spectrum CHIRP runs in Wide and Narrow modes alongside the Low-Q transducer for target separation.

Reviewers single out the side-scan clarity and the compact 7-inch footprint. At 81 ratings averaging 4.5, this is a newer unit with a thinner review history than the others, which is worth factoring into any longevity concern: buyers who want touch controls or deeper chart detail typically step up a model.

Two limits are stated plainly by owners. The interface is button and softkey driven, with no touchscreen, and some units deliver side-scan range shallower than the advertised figure depending on bottom composition and hull. If you are matching existing Humminbird gear, this is the obvious choice; if you are starting fresh with an ecosystem decision pending, read the ecosystem section below first.

Why the Helix 7 G4 is worth the money

SideScan is the feature that turns a fishfinder into a fish-finding tool, and this is a lower-cost route to it in our roundup with the transducer included. The 7-inch screen gives you room to put side-scan next to down-scan, which is exactly how you read structure: a drop-off on one side, a fish ball on the other, both at once.

When to skip the Helix 7 G4

Skip it if you want a glass touchscreen at the helm, because the buttons are not going to change. Also skip it if you are wiring a NMEA 2000 network you plan to grow into, since this unit is built as a standalone head. On a very small jon boat with a narrow console, measure first, because the 7-inch screen plus gimbal bracket needs real flat area.

6. Lowrance Eagle Eye 9 Review – Live Sonar Without a Separate Module

The Eagle Eye 9 exists to solve one problem: giving you a live-sonar view without buying a separate livescope module. The included Eagle Eye transducer feeds Live Forward and Live Down views straight into the display, and the same transducer also provides CHIRP and DownScan with FishReveal, so four sonar modes come from one box on the transom.

The screen is a 9-inch IPS panel rated for readability in direct sun and through polarized sunglasses, which matters more than the spec suggests if you wear glasses on the water. A C-MAP DISCOVER microSD card with US and Canada inland and coastal coverage is included, and the maximum measuring depth is listed at 500 feet.

The box contains the 9-inch display, power cable, gimbal bracket, replacement twist locks, corner clips and the live transducer pack. Panel and bracket mounting are both supported, and the unit weighs 2 pounds, which is the lightest 9-inch in this roundup.

The 45 ratings average 4.1, the lowest figure here, and the reason is specific rather than general: a cluster of reviewers report units that would not power on at all. That is a real reliability signal and we are not going to soften it. If you buy this one, test it thoroughly at the dock before the first trip out.

Against that, the positive feedback is consistent on value. Owners like the live-sonar capability relative to dedicated livescope hardware, praise the screen and the included chart card, and report that the unit runs happily off a small 7Ah battery for a full day. The menu is simple and uncluttered, and the instructions are thin.

Why the Eagle Eye 9 is worth considering

Live Forward shows you fish reacting to the lure in real time, which changes how you fish a jig or a live bait over a flat. Getting that from a single transducer with no external module is unusual at this size and removes a box, a cable and a power feed from the install. For a small boat, fewer boxes is the whole game.

When to skip the Eagle Eye 9

Skip it if reliability matters more to you than live sonar, given the reported power-on failures and a review base of only 45. Skip it if you want a touchscreen, because this is a button-driven unit. And skip it if you need more than 500 feet of range or a heavier transducer for offshore structure, where the 3-in-1 package on the Elite FS is the better bet.

7. Garmin ECHOMAP UHD2 53CV Review – Preloaded Charts in a 5-Inch Footprint

The ECHOMAP UHD2 53CV is an affordable way to put genuine charting on a boat that has almost no console space. It is a 5-inch IPS chartplotter and fishfinder with preloaded Garmin Navionics and U.S. Inland Mapping already on board, which is the thing most entry-level units leave you to buy separately.

Sonar is CHIRP traditional plus CHIRP ClearVu scanning, giving you two views from the standard Garmin install. At 16 ounces it is the lightest console unit here, and both tilt mount and flush mount hardware are supported, so it works on a flat surface bracket or recessed into a molded console face.

Wi-Fi is included for networking with other compatible Garmin chartplotters, which is how you share waypoints between units rather than re-entering them by hand. Note that the sharing feature needs a second compatible Garmin display, so on a single-screen boat you are really buying the option for later.

With 86 ratings averaging 4.5, buyers describe it as an affordable route to real charting on a small boat, with a bright compact IPS screen. The preloaded Navionics coverage is consistently cited as the reason it works on unfamiliar water straight out of the box, which is exactly what the Striker Vivid above cannot do.

Where it falls short is imaging. There is no side-scan and no down-imaging on this model, so structure work is limited to the ClearVu scanning view. And a 5-inch panel is tight when you try to run chart and sonar side by side, so expect to use single-view pages rather than split screens on a small helm.

Why the 53CV fits the smallest consoles

Five inches is small enough to mount on a narrow helm shelf, a trolling motor shaft bracket or a jon boat dash without a cutout. Because it is a flush-mount option as well as a tilt mount, you can recess it into a soft-top console face and keep the profile low, which helps with glare and with clearance behind a small windshield.

When to skip the 53CV

Skip it if you are a side-scan angler, because the imaging package is not there. Skip it if you plan to grow into a multi-display Garmin system, because a 5-inch screen is a poor lead unit for that. And if you want a bundled transducer with the unit, check the box contents carefully, because the transducer is listed separately from this model number and is a frequent add-on at purchase.

8. Garmin Striker 4 Portable Kit Review – For Kayaks, Jon Boats and Ice

The Striker 4 Portable is the odd one out in this roundup, and it earns its place. It is a 3.5-inch color fishfinder with a keyed button interface, CHIRP sonar at 200 W RMS transmit power, and a rechargeable battery in the box, all packed into a carry bag with a foam float and a handle. It is also the most reviewed and highest rated unit we looked at, at 2048 ratings averaging 4.7.

The kit contents matter here: AC charger, the Striker 4, a bag, a foam float, the power and data cable, a rechargeable battery, a tilt and swivel mount, the transducer, and transom, motor and kayak in-hull mounts. That transducer mount list is unusual, and it is what makes this unit genuinely portable across craft types rather than just boat-specific.

There is a built-in flasher mode for ice fishing and vertical jigging, and maximum depth is listed at 1600 feet in freshwater and 750 feet in saltwater. The waypoint map is used for marking brush piles, stumps and docks, which on a lake boat is often the only navigation data you actually need.

Owners describe crisp arches, good target separation and dependable performance in heavy rain, snow and cold conditions, and the rechargeable battery runs multi-day sessions on one charge. The keyed interface is deliberately simple, which is why it is easy to operate with cold or wet hands and why a 3.5-inch screen does not feel like a problem when you are reading a single sonar page.

The limits are equally consistent. There are no preloaded maps, so positioning depends on waypoints and Quickdraw. The 3.5-inch screen is too small for real chart work on open water. The power cable lacks a Y-connector, so recharging means pulling battery terminals rather than leaving the unit on. And documentation is thin, so most owners learn the setup from community videos.

Why the Striker 4 Portable solves real small-boat problems

At 8 ounces, you can move this unit between a kayak, a jon boat and an ice shack in a backpack. That flexibility is the point: for a boat that is used weekends in summer and stored in a garage, a permanently mounted MFD is a lot of commitment for a tool you need a few dozen hours a year. It also makes an excellent backup unit to keep aboard a larger boat.

When to skip the Striker 4 Portable

Skip it if you navigate open or unfamiliar water, because a 3.5-inch screen with no charts is the wrong tool for that job. Skip it if you need AIS, radar overlay or any network integration, none of which is present. And if you plan to run it from a boat battery overnight, the small screen will have you squinting at sonar data all morning.

How to Choose a Chartplotter for a Small Boat

Start with console width, not screen size marketing. A display that is technically excellent and physically will not fit is a wasted purchase, and the difference between a 5-inch and a 10-inch unit is not linear when you are working inside a small console with a windshield in front of it.

Here is the sizing logic we use. For a helm under about 10 inches of usable flat area, a 5-inch class unit such as the ECHOMAP UHD2 53CV or the Helix 5 is the realistic answer. Between 10 and 16 inches, a 7-inch unit gives you split-screen and side-by-side views, which is where the Striker Vivid 7cv and the Helix 7 G4 sit. Above 16 inches and with a full-width console, a 9-inch unit becomes comfortable, and a 10-inch only makes sense if you also have the depth of console to angle it.

Next, decide what the unit has to do. If you only need depth and a waypoint marker for a lake you already know, sonar quality and screen brightness matter more than charting. If you will run unfamiliar water, preloaded charts are worth a lot of money. If you fish structure, side-imaging is the feature that pays for itself, and the transducer inclusion question becomes the most important line in the listing.

Controls are worth thinking about for your specific boat. Touchscreens are easier to learn in a showroom, but a keypad and rotary control that works with wet hands or gloves has a strong case on an open boat in rough water or cold weather. Several of the units here deliberately keep physical controls, and reviewers rate that choice highly.

Finally, think about the ecosystem before you buy, because it is close to permanent. Accessories, transducers, autopilot heads, VHF radios and remote keypads generally only work with their own brand. If you already own Navionics cards or an existing NMEA 2000 backbone, staying inside that family is usually cheaper than starting over. For a second craft that needs its own electronics, our RC boat guide covers how that budget scales down further.

Garmin vs Simrad vs Raymarine vs Lowrance vs Humminbird

The ecosystem matters more than the unit, which is why this is its own section. Accessory compatibility is a hard limit: a transducer, autopilot head, remote keypad or VHF from another brand generally will not pair, and forum consensus treats non-matching-brand compatibility as a dealbreaker rather than an inconvenience.

Garmin has the deepest accessory catalog and the most transferable charting story, because Navionics cards and the ActiveCaptain app work across a wide range of units and, in some cases, across brands. Its small-boat strength is simplicity: the Striker Vivid and ECHOMAP lines are easy to learn and quick to install. Its trade-off is that the imaging packages in the entry units are simpler than what Lowrance offers at similar sizes.

Lowrance leads on feature density per dollar in the value tier, and the Elite FS is the clearest example: a 3-in-1 CHIRP, SideScan and DownScan transducer in the box at a price where competitors sell the transducer separately. The C-MAP DISCOVER charting is preloaded, and the ActiveTarget path gives a genuine upgrade route to live sonar. The cost of that density is a slightly denser interface than Garmin or Simrad.

Simrad tends to be the simpler, more purposeful option, and the GO9 in particular is the most network-ready unit in this roundup with Wi-Fi, Bluetooth, Ethernet, NMEA 2000 and radar capability in one box. Simrad shares its electronics DNA with B&G and Navico, so a dealer who stocks one usually stocks the others. Its bundled transducer is narrower in coverage than a 3-in-1 package, which is the main thing to check.

Raymarine is strong on build quality, sailing features and the Axiom interface, and it is widely available through dealers who do full installations. We did not include a Raymarine in this roundup because the units that suit boats under 22 feet were not in the analyzed set, but if your console is larger than 16 inches it is a serious contender worth pricing alongside the Elite FS.

Humminbird competes on imaging. The Helix 7 G4 with MEGA Side Imaging gives you the widest scan we found for the money, and the button-driven controls are genuinely usable in bad conditions. The trade-off is thinner chart detail out of the box and less of an ecosystem story beyond the transducer line. If you want a clear default: buy within the brand you already own gear for, and choose the size your console can physically host.

What It Actually Takes to Install One

Installation is where small-boat projects stall, so it is worth being concrete. There is a well-documented case of a 9-inch MFD fitted to a 17-foot RIB console that required the windshield to come off and the fiberglass console to be drilled for clearance. That is not a rare horror story; it is what a big display on a small boat looks like when you have not measured.

Measure first. Get the physical width and height of the display bezel, not the diagonal screen size, and compare it to the flat usable area of your console. Then check the depth behind the mount. A surface bracket needs a few inches of clearance; a flush mount needs a cutout and the depth of the housing behind the panel, which is where small consoles run out of room.

Plan the power properly. Fused power distribution is the part DIYers skip and regret, and a proper install means a fused circuit with an inline fuse holder near the battery, a switch, and cable of the right gauge for the run. If you are adding a second battery, an automatic charging relay and a busbar are the components that make the system reliable rather than merely functional.

Route the transducer cable with care. It runs from the transom transducer to the display, and on a small hull the run is often longer than the supplied cable. Measure that distance before you buy, because a short transducer cable is one of the most common install complaints. Mount the transducer where the hull is fair and the boat is at rest, and do not permanently silicone a mounting position you have not tested.

On the GPS antenna, an internal receiver is fine for an open console where sky is visible. Under a hardtop, T-top or enclosed helm, the receiver needs a mast-mounted external antenna to get a clean fix. NMEA 0183 troubleshooting reports most “GPS device not found” errors to a disconnected antenna drop cable rather than a failed unit, so check that connection first when a display loses its position.

Finally, be patient on first power-up. A chartplotter can take up to two minutes to acquire satellites on a cold start, and owners regularly mistake that normal behaviour for a fault. We mention it here because it is the single most common first-day complaint, and because knowing it in advance saves an unnecessary return trip.

Total Cost of Ownership Over Five Years

The display is rarely the whole bill, and the accessory math is what turns an affordable unit into an expensive one. We have kept prices out of the article entirely, so use this as the checklist of what sits outside the headline number rather than a price list.

The transducer. Most units here include one. The Lowrance Elite FS, Garmin Striker Vivid 7cv, Humminbird Helix 5, Simrad GO9, Humminbird Helix 7 G4, Lowrance Eagle Eye and Garmin Striker 4 Portable all bundle a transducer. The ECHOMAP UHD2 53CV is commonly offered in a bundle with a GT20-TM, so check the specific model number. If a listing does not name a transducer in the box contents, assume you are buying it separately at roughly the cost of the display’s smaller sibling.

The mount. Most units include a bracket or gimbal kit. The Elite FS supports bracket, surface and flush mounting, and the ECHOMAP UHD2 53CV supports tilt and flush, so a recessed install may be free. A RAM-style articulating mount for a trailered boat is an extra purchase and we consider it worth it, because it is what absorbs road vibration on the way to the ramp.

Wiring and fusing. Fuses, fuse holders, terminals, heat shrink, strain relief and the right cable gauge are consumables that rarely make the marketing copy. The Helix 5 in particular does not include an inline fuse or extra cable length, and reviewers call that out repeatedly on small boats with long cable runs.

Installation labour. On a small boat, the difficult part is not the display, it is drilling a fiberglass console, running cable through a bulkhead and doing the fused power correctly. Budget for a professional if you have not done marine wiring before, because a bad install shows up as a dead display or a swamped battery, not as a small inconvenience.

Charts. Units that include preloaded coverage keep year one free, and that is the case for the Elite FS, the Simrad GO9, the Lowrance Eagle Eye and the ECHOMAP UHD2 53CV. Units that do not, such as the Striker Vivid 7cv, shift the cost to you at some point. Subscription services like Navionics+ and C-MAP are annual; LakeMaster, CoastMaster and lifetime-style chart options exist for people who want a one-time purchase.

Running the numbers this way usually changes the ranking. A cheap display that needs a transducer, a card, a mount and a shop install can easily cost more than a mid-tier unit that includes the transducer and the charts. That is why most of our eight recommendations bundle a transducer, and why we read the box contents before the headline number.

Chartplotter vs Phone or Tablet

This is the highest-frequency question in boating forums and the one most roundups skip, so here is the honest version. A modern phone or tablet running a charting app can do a surprising amount of what a fixed MFD does: full vector charts, tide and current data, weather overlay, route planning and waypoint management, all on hardware you already own and update for free.

Where the tablet wins is cost and flexibility. There is no install, no wiring, no transducer and no console drilling, and you can change apps or chart providers. For a boat that is used a few times a year on a familiar lake, a mounted tablet plus a waterproof case is a legitimate and inexpensive solution, and several sailors run exactly that combination deliberately alongside a handheld for the position fix.

Where the fixed display wins is reliability at the helm. A phone or tablet depends on battery charge, weather, glare, an app update and a case that survives a splash, and in bright sun a glossy tablet screen is harder to read than a sunlight-rated MFD. A permanently powered unit with a backlight dimming schedule and a capacitive screen that works with wet fingers simply does not have those failure modes. Forum consensus broadly prefers the plotter for always-on reliability while acknowledging the tablet wins on cost and chart flexibility.

Our practical take for boats under 22 feet: if your boating is lake-based and infrequent, the Striker 4 Portable or a mounted tablet is honest value. If you run coastal water, in fog, at night, or with a hardtop that hides the sky, a fixed chartplotter earns its place. The cheapest hybrid is a tablet for chart work plus a portable unit for the raw position and depth numbers.

Chart Subscriptions vs Bundled and Lifetime Charts

Chart subscription fatigue is real and it is the most common reason people hesitate on this purchase, so it deserves a clear section. A subscription chart service gives you regular updates, detailed coastal and fishing contour data and new features, and it is the best option if you fish unfamiliar or changing water where stale depth data is genuinely dangerous.

The objection is that the cost recurs every year forever, and it does so whether you use the unit or not. The ways to avoid or reduce it are straightforward. Buy a unit with preloaded onboard charts and use them for the first season with no added spend. On inland water, a bundled basemap covering thousands of lakes plus your own Quickdraw contours is often all you will ever plot on.

There are also one-time and card-based options. LakeMaster and CoastMaster are sold as card or module-based products rather than annual services, and the Humminbird Helix units in this roundup accept both alongside Navionics cards. A Navionics card bought outright gives you full charting with no recurring fee, at the trade-off of manual updates.

Our advice is to treat the subscription decision separately from the hardware decision. Buy the display that fits your console and your sonar needs, then choose charts based on the water you actually run. That way a subscription refusal never pushes you into the wrong hardware, and a subscription acceptance does not push you into a bigger screen than the boat can host.

Frequently Asked Questions

Final Word

If you take one thing from this roundup, make it the console measurement. Every problem we saw described in real installations, from drilled fiberglass to cramped screens, comes back to fitting a display that was chosen off a spec sheet rather than a tape measure.

With that done, the Lowrance Elite FS is our default recommendation for the best marine GPS chartplotters for small boats, because the transducer and the charts are already in the box and the connectivity lets you grow into a bigger system later. If your console is under 16 inches wide, the Garmin Striker Vivid 7cv is the better physical fit. Pick the Humminbird Helix 5 CHIRP G3 when the budget is the deciding factor, the Humminbird Helix 7 G4 when side-scan coverage is the priority, and the Garmin Striker 4 Portable Kit when the boat is small, seasonal or shared between craft.

Whichever you choose, budget for the transducer, the mount, fused wiring and the install before you order the display. It is the difference between a sensible upgrade and an expensive lesson. If you are still fitting out the rest of the boat, our rod holder guide covers the other end of the console, and our boat dehumidifier guide is worth a look if you store the boat over winter.
