Humminbird Helix 5 CHIRP GPS G3 review: is the cheapest Helix worth it
Quick answer
The Humminbird Helix 5 CHIRP GPS G3 is a 5 inch, $339.37 fish finder with Dual Spectrum CHIRP sonar and built-in GPS covering more than 10,000 lakes. It has no side imaging, so buy it for clean 2D sonar and mapping, not for scanning water beside the boat.
The Helix 5 CHIRP GPS G3 sits at the bottom of Humminbird's Helix lineup, and it exists to answer one question: can a buyer get real Dual Spectrum CHIRP sonar and a usable chartplotter for under $350 without stepping down to a no-name brand. On paper, the answer is yes. It has a genuine two-mode CHIRP transducer, a built-in Basemap with over 10,000 lakes charted, and the same keypad interface Humminbird has used across the Helix range for years.
This review is built from Humminbird's published specification sheet for this control head and the recurring themes in verified owner reviews, not from time spent running the unit ourselves. Where the manufacturer has not published a figure, that gap is called out rather than guessed at, which matters most on the one question this page answers first: what actually ships in the box.

What is actually in the box
The Helix 5 CHIRP GPS G3 is Humminbird's entry point into the Helix line, and listing photos do not always make clear whether a transducer ships with the head. The published specification sheet for this unit does not name a bundled transducer model, which is the same pattern several other Helix listings follow. Before ordering, read the actual title and the included items list on the listing you are buying, not just the product photo, because two listings under the same model name can differ on this point.
If your listing turns out to be control head only, the standard XNT 9 20 T transom transducer is the plain dual beam unit with a built-in temperature sensor that Humminbird sells as the standard replacement across most of the Helix range, and it is the correct match for a 2D only head like this one that has no side imaging or down imaging to support.
How the Helix 5 G3 compares on paper
At its price, the Helix 5 G3 is competing against units that either cost less and give up chart coverage, or cost about the same and add a transducer to the box. The table below lines up three real entry level options on published specifications.
The Helix 5 G3 costs $339.37 for a 5 inch screen with a built-in Basemap, while the Eagle 5 SplitShot HD undercuts it and still ships with C-MAP charts preloaded.
Published figure A published engineering, regulatory or manufacturer figure. It does not change because somebody disagrees with it.
| Unit | Screen | Sonar | Charts included | Price |
|---|---|---|---|---|
| Humminbird Helix 5 CHIRP GPS G3 | 5 in | Dual Spectrum CHIRP | Humminbird Basemap, 10,000+ lakes | $339.37 |
| Garmin Striker Vivid 4cv | 4 in | CHIRP traditional and ClearVu | Quickdraw Contours, self-built only | $199.99 |
| Lowrance Eagle 5 SplitShot HD | 5 in | CHIRP and DownScan | C-MAP US Inland, 17,000+ lakes | $326.48 |
Prices and chart coverage are each maker published figure at the time this table was built, not a live guarantee.
What owners say once the newness wears off
Based on published specifications and the recurring themes in verified owner reviews, three patterns repeat on the Helix 5 G3. First, the physical keypad gets more praise than expected next to touchscreen competitors, because wet or gloved fingers hit a button reliably where a touchscreen target gets missed. Second, the built-in Basemap gets credited as accurate on inland lakes, with owners noting it finds boat ramps and channel markers without a separate chart card purchased on top.
Third, and this is the complaint that has nothing to do with the sonar itself: several buyers report being surprised that their specific listing did not include a transducer, which is exactly the trap covered above and worth checking before you click buy.
What is wrong with the Helix 5 G3
The screen is the real limitation. At 5 inches, splitting the display between a sonar view and a chart page shrinks each pane to a size that is hard to read from a standing position at the helm, and there is no side imaging or down imaging mode to grow into later, since the hardware in this head does not support either. Anyone who expects to add MEGA imaging down the road needs a different control head, not a software update.
The second compromise is the one already covered above: whether a transducer ships with your specific listing is not guaranteed, and a $339.37 head that then needs a separate transducer on top is not the deal it first looks like on a listing page.
Helix 5 G3 against the rest of the entry level Helix range
| Specification | Humminbird Helix 5 CHIRP GPS G3 | Humminbird Helix 5 CHIRP DI GPS G3 | Humminbird Helix 7 CHIRP SI GPS G4 |
|---|---|---|---|
| Price | $339.37 | $370.74 | $579.99 |
| Screen size | 5 in | 5 in | 7 in |
| Sonar | Dual Spectrum CHIRP | Dual Spectrum CHIRP and Down Imaging | Dual Spectrum CHIRP and Side Imaging |
| Built-in GPS | Yes | not published | Yes |
Every figure above is the manufacturer own published specification. Where a maker does not publish a figure the cell reads "not published" rather than carrying an estimate, because on ratings and currents an estimate that reads as a specification is a safety problem rather than a gap.
What to buy instead of the Helix 5 G3
If down imaging matters even a little, the Helix 5 CHIRP DI GPS G3 is the same head with down imaging added, and it is the single most requested upgrade among Helix 5 owners after the fact. For a genuinely bigger step, the Helix 7 CHIRP SI GPS G4 adds a two inch larger screen and side imaging, which is the price most boat owners settle on once they have used a 5 inch screen for a season and found it small.
Anyone who wants a chart card included in the box rather than relying on a built-in basemap should look at the Lowrance Eagle 5 SplitShot HD, which ships with C-MAP US Inland charts already loaded and costs about the same as this unit.
How we chose
We did not test this equipment in person and we never claim to. Picks are researched from manufacturer specification sheets, published engineering and regulatory figures, and the recurring themes in verified owner reviews. Every pick is matched to a real thrust rating, a real published amp draw, a real capacity or a real conductor size rather than to a price bracket, and it is placed in the tier where its published capability actually belongs. We rejected the unbranded flood that dominates several of these search results, because a lithium pack whose management board is the only thing between a cell fault and a fire, a breaker protecting a battery cable, a life jacket and a bracket holding a two thousand dollar motor to the bow at highway speed are all parts whose failure has a consequence nobody can walk away from. Where a figure is convention rather than a published standard we label it that way, and where a manufacturer does not publish a figure we leave it out instead of estimating it.

Frequently asked questions
Does the Humminbird Helix 5 CHIRP GPS G3 come with a transducer?
It depends on the specific listing you buy, and the published specification sheet for this control head does not name a bundled transducer model. Read the exact title and included items list before ordering. If your unit arrives as control head only, the XNT 9 20 T is the standard dual beam transducer with a temperature sensor that Humminbird sells as the replacement across most of the Helix range, and it is the right match for a 2D only head like this one.
Does the Helix 5 G3 have side imaging or down imaging?
No. The G3 hardware in the 5 inch Helix supports Dual Spectrum CHIRP traditional sonar and GPS with the built-in Basemap, but it has no side imaging or down imaging mode. For down imaging on the same size screen, the Helix 5 CHIRP DI GPS G3 is the version to buy, and for side imaging you need to move up to a seven inch Helix head entirely.
How accurate is the built-in Basemap compared to a Navionics card?
Humminbird publishes coverage of more than 10,000 lakes and the continental United States coastline in the built-in Basemap, and the head also accepts premium LakeMaster, CoastMaster and Navionics cards for more detail. Verified owner reviews consistently describe the free Basemap as good enough for finding ramps, channels and basic contours on inland lakes, with the paid chart cards reserved for anglers who want depth contours precise enough to fish specific breaks.
Is a 5 inch screen big enough for a fish finder?
A 5 inch screen works well running a single full screen sonar view, and it is a genuine step up from a 4 inch unit. It gets cramped the moment you split it between sonar and a chart page, because each pane shrinks to roughly half of an already small screen. Anyone who plans to run a chart page most of the time on the water should budget for a 7 inch head instead of this one.
What is Dual Spectrum CHIRP?
Dual Spectrum CHIRP is Humminbird's term for a CHIRP sonar signal that runs in two published modes from the same Low-Q transducer: a wide mode for maximum coverage and a narrow mode for detailed scanning of a smaller area. It is a genuine CHIRP implementation rather than older single frequency sonar, and it is the same core sonar engine used across the wider Helix G3 and G4 lineup, including the larger side imaging heads.
Is the Helix 5 G3 worth it over a cheaper unit like the Garmin Striker 4?
The Helix 5 G3 costs roughly $339.37 against about $139.99 for a base Garmin Striker 4, and the difference buys a larger screen, Dual Spectrum CHIRP with two search modes, and built-in Basemap chart coverage the Striker 4 does not have. If chart coverage and a bigger screen matter to how you fish, the price gap is worth it. If all you want is a basic depth and fish alarm, the cheaper unit does that job too.

Researched, not professional advice. This page is compiled from published engineering and regulatory figures, manufacturer specifications and owner-review consensus, not hands-on testing. Figures described as a rule of thumb are boating convention rather than published standards, and they are labelled that way wherever they appear. Marine electrical work is not house wiring. Use tinned, finely stranded marine cable, size it for voltage drop and for the ABYC E-11 ampacity table rather than one or the other, and put overcurrent protection within seven inches of the battery positive terminal, because everything between the post and the fuse is unprotected. A lithium battery needs a charger with a lithium profile. Never load a boat past its capacity plate, and remember that canoes and kayaks carry no federal capacity plate at all, so their stated capacity is the manufacturer own figure. Wear the life jacket, and treat early season water as the hazard it is: cold water immersion takes your breath and then your hands long before it takes your core.
