You need a chartplotter fishfinder combo to see what is under your boat and to mark the exact spot where you found fish so you can return to it. Your choice hinges on your fishing style and the screen size you can read in direct sun.
I’m Mo Maruf — the founder and writer behind The Tools Trunk. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
Screen size, sonar type, and mapping capability decide which combo fits your boat.
Our Picks at a Glance
How To Choose The Best Chartplotter Fishfinder Combo
A chartplotter fishfinder combo pairs a GPS navigation screen with sonar that reads the water below. Before you pick one, match the sonar type and screen size to the kind of fishing you do most, because a unit built for ice fishing behaves very differently from one built for a fast center console.
Sonar Types: 2D, Side Imaging, and DownScan
Traditional 2D sonar shows fish arches directly under the boat. Side imaging scans a wide swath to the left and right, letting you spot structure and fish before you cast over them. DownScan gives a photo-like view of the bottom straight below. Many combos combine two or three of these, so think about whether you fish open water, tight cover, or a mix of both.
Screen Size and Readability
Bigger screens show more detail and split-view options, but they cost more and take up more console space. A 5-inch display suits a small boat or kayak, while a 7-inch or 10-inch screen makes side imaging and mapping much easier to read. Look for a bright, sunlight-readable panel — a washed-out screen is useless on a sunny day.
Mapping and GPS Features
Built-in maps save you from buying chart cards, but some units only mark waypoints and build contours as you drive. Quickdraw Contours and AutoChart Live create and store depth maps while you boat, so you never rely on preloaded data. If you fish unfamiliar water, a unit with preloaded lake coverage or a bundled map card is worth the extra cost.

In-Depth Reviews
1. Garmin Striker Vivid 7sv
Our pick — over 4.5★ from 450+ verified ratings; the strongest balance of quality and price.
The side-scan king that turns a 7-inch screen into your underwater eyes.
This is the combo that helped a kayaker upgrade from the older Striker 7sv and start spotting fish on side scan, casting over to that area, and catching them — the exact workflow everyone hopes for. The 7-inch color display runs vivid scanning sonar color palettes that separate fish from structure at a glance, so you are not squinting at gray blobs.
It supports Garmin CHIRP traditional sonar plus CHIRP ClearVü and CHIRP SideVü scanning sonars through the included GT52HW-TM transducer, which bolts on with a tilt/swivel mount. The high-sensitivity GPS marks waypoints, creates routes, and shows your boat’s speed, while built-in Quickdraw Contours mapping lets you build your own depth charts as you drive.
Wi-Fi connects the unit to the ActiveCaptain app on a compatible smartphone, which handles waypoint transfers, smart notifications, and software updates. The honest trade-off is that it ships without factory maps — if you want preloaded charts, you need a different model. On a small 12-foot semi-v, owners find it works well, and the controls are intuitive enough that the install feels simple.
What wins people over
- Side scan is the standout — owners learn to spot fish and cast right to them
- Easy install and intuitive controls on a 7-inch vivid display
- Wi-Fi to ActiveCaptain app for waypoint and software management
What to know before buying
- No factory maps included — you build contours yourself
- Mapping-focused anglers may want a model with preloaded charts
Reach for this if: you want SideVü scanning and a bright 7-inch screen without paying for preloaded maps.
Look elsewhere if: you need turnkey lake charts from the start — this unit expects you to create them.
2. Humminbird Helix 5 Chirp GPS G3
A compact keypad-controlled unit that packs real GPS mapping onto a 5-inch screen.
For anglers who want navigation muscle without a touchscreen, this Helix 5 delivers Dual Spectrum CHIRP sonar with two search modes — Wide Mode for broad coverage and Narrow Mode for fine detail. The low-profile footprint fits a 20-foot pontoon boat, where buyers report the included cable was just enough to reach the console.
Enhanced GPS comes standard with Humminbird Basemap, giving you coverage of 10,000+ lakes and continental U.S. coastlines right from the start, and it is compatible with premium LakeMaster, CoastMaster, and Navionics charts when you want more detail. Real-time AutoChart Live builds maps of depth contours, bottom hardness, and vegetation while you boat, with eight hours of built-in recording time.
What wins people over is the functionality — split-screen views let you watch speed, route, and sonar at once, while the softkey controls stay reliable in any weather. The depth measurement draws mixed feedback: some find it super accurate, while others note it does not read while under way at speed. For a basic, economical unit with crisp, sunlight-readable screen clarity, it is a fair price for quality equipment.
Solid all-rounder: real GPS mapping, AutoChart Live, and keypad reliability in a compact 5-inch package.
One caveat: depth readings can drop out when you are moving fast, so plan around trolling or anchored use.
3. Garmin STRIKER Plus 5cv
A no-manual-needed 5-inch combo that marks fish spots while you troll.
This entry-level unit pairs a 5-inch sunlight-readable display with the CV20-TM transducer for built-in Garmin CHIRP traditional sonar plus CHIRP ClearVü scanning sonar. Owners call it a really good budget setup — one that needs no manual and works straight from the start.
Built-in GPS marks waypoints, creates routes, and views your boat’s speed, and the Quickdraw Contours software lets you create and store maps with 1-foot contours for up to 2 million acres. Owners mention it maps and marks fish spots while trolling, accurate to a few feet along routes — a consistent strike zone for lake trout.
The rugged design suits every fishing environment, but there is a real limit: no depth reading above 15 MPH, so it is solid at trolling speeds but not built for high-speed running. For a tabletop-mounted unit on a small boat, that trade-off is easy to live with — and the intuitive interface is the reason it earns near-universal praise.
Why it is a keeper
- Truly easy to use with no manual needed
- Accurate waypoint marking while trolling — within a few feet
- Compact 5-inch display that stays readable in sunlight
The honest limit
- No depth reading above 15 MPH — trolling only
- Smaller screen means less split-view room
Choose this for: a first combo on a kayak or small boat where simplicity beats raw power.
Think twice if: you run fast between spots and expect continuous depth readouts.
4. Garmin Striker Plus 7Cv
A 7-inch screen made for aging eyes that still keeps install dead simple.
This 7Cv brings a bright, sunlight-readable 7-inch WVGA display and an intuitive interface that one owner found much easier on old eyes than a smaller Striker 4. The CV20-TM transducer delivers built-in Garmin CHIRP traditional sonar plus CHIRP ClearVü scanning sonar, so you get clean bottom detail without juggling multiple transducers.
It steps up from the 5-inch STRIKER Plus 5cv with a display that is 40% larger — a meaningful jump when you are trying to read contours in glare. Built-in Wi-Fi connects to the ActiveCaptain app for smart notifications, Quickdraw Contours Community access, and waypoint transfers, while the built-in GPS marks waypoints, creates routes, and shows boat speed.
Owners call it the best thing they ever bought for their boat, praising easy installation and a 16-hour battery life for the unit itself. The recurring complaint is that it arrives without maps — you build contours with Quickdraw Contours, and some buyers were surprised there was no chart card included. It is also worth knowing you have to be in the water to adjust the keel offset.
Big-screen value: a 7-inch WVGA panel and Wi-Fi app support make this the comfortable middle ground.
Read the fine print: no preloaded maps, and keel offset only adjusts while the boat is in the water.
5. Humminbird Helix (Portable Bundle)
A grab-and-go Helix with its own battery that shines for ice fishing.
This portable Helix bundles the fish finder control head with a suction cup mount transducer, a shuttle bag, and a 7Ah AGM battery with charger — everything you need to fish from a kayak, rental boat, or an ice hole. Owners who love it for ice fishing say it is much better than a flasher, with clear images that show what is actually below.
The sonar is the same Dual Spectrum CHIRP found on the fixed Helix units, with Wide and Narrow modes, and the built-in GPS includes Humminbird Basemap covering 10,000+ lakes and continental U.S. coastlines. AutoChart Live recording gives you eight hours of built-in time to map depth contours, bottom hardness, and vegetation as you fish.
Customers note the screen is clear and the data is rich, but there is a learning curve — one owner called it a beautiful tool that takes time to learn to read. The included 2D skimmer transducer only works up to about 15 MPH, so this is not a high-speed dash unit. The maximum measuring depth of 3000 feet gives you serious range for deep water.
Why it travels well
- Comes with battery, charger, and shuttle bag for true portability
- Clear screen and rich data that beat a traditional flasher
- 3000-foot max depth for deep water and ice fishing
What to expect
- Steep learning curve for reading the rich sonar data
- Transducer tops out around 15 MPH
Grab this if: you want one unit that moves from ice shack to rental boat without rewiring.
skip it if: you need a permanent high-speed dash installation.
6. Simrad GO9 Chartplotter
A 9-inch touchscreen multifunction display that turns your boat into a connected command center.
This GO9 is a true multifunction display — add GPS navigation, sonar support, and radar capability to sportboats, center-consoles, and smaller cruisers. The large touch screen and brilliant display make charts and echo easy to view in any conditions, and owners upgrading from a GO7 say the Simrad Go series is super intuitive and user-friendly.
The included C-MAP DISCOVER card brings full-featured Vector Charts, Custom Depth Shading, Tides & Currents, and high-resolution bathymetric contours with ultra-wide coverage across the US and Canada. A built-in 83/200 kHz HDI transducer supports clear CHIRP sonar and DownScan Imaging to identify bottom structure and fish targets, so you get real chartplotting value right from the start.
Built-in Wi-Fi and NMEA 2000 support let you mirror the display to a smartphone or tablet, giving you access to charts and radar from anywhere on board. Owners praise the quality and price point, with one noting it provides way more info than previous units and works right from the start on a 1958 32-foot Chris Craft Commander.
Super intuitive: a fast touchscreen and C-MAP Discover card make this the easiest premium unit to live with.
Know this: built for boats that can use its network features — radar and NMEA 2000 integration are where it truly shines.
7. Lowrance Elite FS 10
A 10-inch touchscreen that shows exactly which side of the boat the fish are on.
This Elite FS 10 pairs a large 10-inch touchscreen with an Active Imaging 3-in-1 transducer that delivers CHIRP, SideScan, and DownScan with FishReveal sonar. One owner on Lake Stevens credits it for six straight trips pulling limits of kokanee — when the sonar shows a school off to the side, you switch to side scan, find the side the fish are on, and mark them.
It is live sonar compatible with ActiveTarget 2 XL, so you can add real-time views later, and the high-detail contour mapping highlights ledges, drop-offs, and productive fishing zones. The touchscreen interface makes it easy to adjust sonar and charts in changing conditions, and it integrates with trolling motors and marine electronics for centralized boat control.
Reviewers point out crisp image quality and a straightforward setup that comes with everything required for installation. The catch is a learning curve — anything with this many options takes time to master, and some find the value-for-money slightly mixed. At 1000 feet of maximum measuring depth, it has plenty of range for most freshwater and coastal fishing.
Why it is a favorite
- 3-in-1 transducer with SideScan, DownScan, and CHIRP
- Live sonar compatible with ActiveTarget 2 XL for future upgrades
- Large 10-inch touchscreen with high-detail contour maps
The trade-off
- Steep learning curve with so many options and functions
- Value-for-money opinions are mixed among owners
Best for: serious anglers who want side imaging and live sonar readiness on a big touchscreen.
Consider otherwise if: you want simple, instant operation — this unit rewards patience and setup time.
8. Garmin ECHOMAP Ultra 2 LiveScope Plus Bundle
LiveScope Plus turns a 10-inch touchscreen into real-time underwater video of fish and structure.
This bundle pairs the ECHOMAP Ultra 2 with a LiveScope Plus transducer, giving you real-time sonar views that show fish moving in live motion — a considerable upgrade to any boat. The crisp, bright, sunlight-readable touch-screen display uses vivid, high-contrast color palettes, and owners say it is versatile enough for ice fishing as well as open water.
Built-in Garmin Navionics+ mapping comes with a 1-year subscription for daily updates, so your charts stay current without buying new cards. Wi-Fi lets you wirelessly share information with other Ultra 2 or UHD2 fish finder and chartplotters on your boat, and the touchscreen works alongside button inputs for quick adjustments.
Owners describe it as amazing — the reason they would not boat without it — though a few note the unit may arrive as older stock with out-of-date software that needs updating. One reviewer noted a screen size discrepancy, which is worth verifying before purchase. At 17 pounds for the bundle, this is a substantial investment in seeing fish in real time before you cast.
Why it is a standout
- LiveScope Plus shows fish and structure in real-time motion
- Navionics+ built-in with a 1-year daily-update subscription
- Wireless sharing with other compatible Garmin units
What to watch for
- Some units arrive as older stock with outdated software
- Heavy bundle at 17 pounds — plan your mounting and wiring
Step up to this if: you want the most advanced live sonar view available and fish both open water and ice.
Think twice if: you are new to sonar — the learning curve and price point suit experienced anglers.
Understanding the Specs
CHIRP Sonar
CHIRP (Compressed High-Intensity Radiated Pulse) sends a sweep of frequencies instead of a single tone, which gives you sharper target separation and cleaner fish arches. Traditional 2D sonar shows a simple cone below the boat, while CHIRP variants like ClearVü and SideVü give you photo-like down views or wide side scans. If you mostly fish structure or need to distinguish fish from weeds, CHIRP is the feature that matters most.
Screen Size and Readability
Screen size determines how much you can see at once — a 5-inch display is fine for basic 2D sonar, while 7-inch and 10-inch panels let you run split views of mapping and side imaging side by side. Brightness matters just as much: a sunlight-readable display keeps charts visible on a glare-heavy day. Match the screen to your boat console space and your eyesight.
