Garmin Striker vs Humminbird Helix: Which Line Fits How You Fish
Garmin Striker vs Humminbird Helix: ClearVü down imaging and your own Quickdraw maps, or CHIRP sonar with a preloaded basemap. Who each one suits.
Updated October 29, 2026
Garmin Striker vs Humminbird Helix is mostly a choice between imaging and charts at the entry level. The Garmin Striker Vivid 5cv adds ClearVü down imaging to its 2D sonar, and Garmin lists no preloaded charts for it; you build your own contour maps with Quickdraw Contours as you drive. The Humminbird HELIX 5 CHIRP GPS G3 lists Dual Spectrum CHIRP sonar and names no imaging view, according to its Amazon listing, but it comes with the Humminbird Basemap and live mapping. If you fish one home lake and want to see brush and rock under the boat, the Striker is the better fit. If you trailer to different lakes and want a preloaded lake basemap from day one, the HELIX makes more sense.
Both names cover families. Garmin’s runs from the 3.5 in Striker 4 to the Striker Vivid units and the Striker Cast; we leave the Striker Plus aside because several of its U.S. pages did not load. In the listings we read, the HELIX line runs from the HELIX 5 to the HELIX 7 G4 and G4N with MEGA imaging. Humminbird lists the HELIX 5 CHIRP GPS G3 among its current HELIX products; HELIX screen, power, and imaging figures here come from Humminbird’s HELIX operations manual and control head installation guide, the rest from the Amazon listings.
This guide is general product information, not repair or electrical safety advice. Follow the installation, wiring, and charging instructions in your product’s manual, stop using any battery, charger, or electronics that overheat, swell, or smell of burning, and contact the manufacturer.
The Two Units in This Comparison
We compare the Garmin Striker Vivid 5cv and the Humminbird HELIX 5 CHIRP GPS G3, two entry-level units sold with a transducer in the box. They stand in for their families and are not a ranking. Neither listing had owner review text we could read, so this comparison rests on the maker’s documents for the Garmin and the listings for both.
The score on each card is its AnglerTechLab Score, calculated with the published method on our How We Review page; it is one factor in how we describe a product, not the result of a head-to-head comparison. Neither score has an editorial adjustment.

Garmin Striker vs Humminbird Helix: Specs Side by Side
Sources: Garmin’s Striker Vivid 5cv page, Garmin’s GT20-TM transducer page, the STRIKER Vivid owner’s manual, Humminbird’s HELIX manual and installation guide, and the two Amazon listings. HELIX figures marked per Humminbird come from its documents; the rest are from its listing. Where no source states a figure, the cell says so.
| Feature | Garmin Striker Vivid 5cv | Humminbird HELIX 5 CHIRP GPS G3 |
|---|---|---|
| 2D sonar | Traditional 50/77/200 kHz, CHIRP mid and high (per Garmin) | Dual Spectrum CHIRP with Wide and Narrow modes (per the listing) |
| Imaging | ClearVü down imaging with the included GT20-TM (per Garmin) | None named in the listing |
| Transducer in the box | GT20-TM, with transom and trolling motor mounts (per Garmin’s GT20-TM page) | XNT 9 HW T transom-mount transducer (per the listing) |
| Display | 5.0 in (about 2.6 x 4.3 in), 800 x 480 pixels (per Garmin) | 5 in, 800 x 480 pixels (per Humminbird) |
| Preloaded charts | None; Garmin says its Quickdraw maps do not contain detailed mapping | Humminbird Basemap with 10,000+ lakes and continental U.S. coastlines (per the listing) |
| Map you record | Quickdraw Contours, 1 ft contours, up to 2 million acres (per Garmin) | AutoChart Live: depth contours, bottom hardness, vegetation, eight hours of recording (per the listing) |

| Controls | Keyed (per Garmin) | Keypad and softkeys (per the listing) |
| Power input | 12 to 20 Vdc (per Garmin) | 10 to 20 VDC; 12 VDC supply with a 3 A fuse (per Humminbird) |
| Warranty | 2-year limited (per the listing) | 1 year (per the listing) |
Sonar: Down Imaging on the Striker, No Imaging Named for the HELIX 5
This is the biggest gap between the two units. The Vivid 5cv’s GT20-TM runs traditional CHIRP for fish arches plus ClearVü, which the STRIKER Vivid manual says produces “a clearer, picture-like image of what is beneath the boat.” On a brush pile or a rock hump you already have marked, that picture shows the shape of the cover rather than a blob on the bottom line.
The HELIX 5 CHIRP GPS G3 listing describes Dual Spectrum CHIRP with two search modes, Wide for coverage and Narrow for detail, and names no down or side imaging. That reads depth, bottom, and fish arches, but not a picture of structure. If you want imaging in the HELIX family, Humminbird puts it on other models: the HELIX 7 G4N MEGA DI reaches 125 ft below the boat with its MDI transducer, and Humminbird’s manual lists the HELIX 7 G4 MEGA SI (Amazon listing) at 125 ft to each side and 75 ft below; that listing gives 125 ft for both. On the Garmin side, the Striker Vivid 7sv and 9sv add SideVü, per Garmin’s Vivid lineup specs. Our side imaging vs down imaging comparison covers which view suits which kind of fishing.
Maps: Record Your Own or Start With a Basemap
Here the HELIX 5 pulls ahead. Its listing says it ships with the Humminbird Basemap covering 10,000+ lakes and continental U.S. coastlines, is compatible with LakeMaster, CoastMaster, and Navionics charts, and adds AutoChart Live, which records depth contours, bottom hardness, and vegetation as you drive, with eight hours of built-in recording time and AutoChart Zero Line SD cards for more. On a lake you have never fished, a preloaded basemap gives you something on the screen before you launch; the listing does not say how much detail it holds.
The Striker Vivid 5cv takes the opposite approach. Garmin lists Quickdraw Contours as its only map support and notes that Quickdraw “does not contain detailed mapping” and that the content is user-generated. On a home lake you fish every weekend, Quickdraw lets you build a 1 ft contour map of exactly that water, up to 2 million acres per Garmin; on a new reservoir it starts blank. Both units have GPS, per Garmin and the HELIX listing, so the deciding factor is the map, not navigation.
Screen, Controls, and Connectivity
Garmin lists the Vivid 5cv at 5.0 in diagonal with 800 x 480 pixels. Humminbird’s HELIX manual lists the same 5 in and 800 x 480 pixels for the HELIX 5 CHIRP GPS G3, so on paper the two screens match. Both are button-driven: Garmin lists keyed input, and the HELIX listing describes keypad and softkey controls.
Neither listing names networking for these two units. Garmin’s Vivid specs list a Wi-Fi network for the ActiveCaptain app on the 7 in and larger Vivid models, not on the 4cv or 5cv. In the HELIX line, the HELIX 7 G4N listing names Ethernet ports, Bluetooth, and built-in NMEA 2000, plus integration with Minn Kota and Cannon products; the HELIX 5 listing mentions none of those. If you want your fish finder to talk to a trolling motor, look at the G4N, and note that its listing is for the control head only, with no transducer.
Mounting, Power, and Portable Use
The Garmin’s GT20-TM ships with both transom and trolling motor mounts, per Garmin’s transducer page, which also tells you to follow the installation instructions carefully to avoid damaging your boat. The HELIX 5 listing names an XNT 9 HW T transom-mount transducer and does not list a trolling motor mount, so if you fish off a bow-mounted trolling motor, check what mount you would need.
Garmin lists a 12 to 20 Vdc power input for the Vivid 5cv, and the STRIKER Vivid manual says the device will not turn on below 12 Vdc. Humminbird’s manual lists a 10 to 20 VDC power input for the HELIX 5, and its installation guide calls for a 12 VDC supply with a 3 A fuse. For the wiring itself, follow each maker’s installation instructions and leave anything beyond them to a qualified marine electrician.
For kayaks and portable use, Garmin has the clearer path on paper. Its Portable Fishing Kit page says the optional kayak in-hull mount secures a GT20-TM to the kayak, and the kit adds a bag, battery, charger, and suction cup transducer mount. Garmin also makes the Striker Cast, a 2.6 oz castable sonar that pairs with a phone over Bluetooth, for anglers with no mount at all. For hard water, Humminbird sells a separate HELIX 5 CHIRP G3 Ice Sonar System kit, according to its Amazon listing, and our list of the best ice fishing fish finders compares it with Garmin’s ice bundle.
Which Should You Buy?
- You fish one home lake from a small boat: the Garmin Striker Vivid 5cv. ClearVü shows the cover you keep returning to, and Quickdraw builds a map of exactly that water; our Garmin Striker Vivid 5cv review covers it in depth. Skip it if you want preloaded lake maps or Wi-Fi, which Garmin lists only on larger Vivid models.
- You trailer to new lakes: the Humminbird HELIX 5 CHIRP GPS G3, for the basemap and premium chart compatibility named in its listing. Skip it if you want a picture of structure or mount on a trolling motor; its listing names no imaging and a transom-mount transducer.
- You want side imaging on a bigger screen: the HELIX 7 G4 MEGA SI (per Humminbird) or Garmin’s Striker Vivid 7sv and 9sv (per Garmin). Skip both if you lack a transom or hull position where the transducer can see both sides.
- You run a Minn Kota and want the units to work together: the HELIX 7 G4N, whose listing names NMEA 2000 and Minn Kota integration. Skip it if you want a complete kit; the listing is for the control head only.
- You want the simplest Garmin with GPS: the 3.5 in Striker 4, which Garmin’s Striker 4 page lists with traditional CHIRP, a built-in flasher, and keypad operation. Skip it if you want imaging or a larger screen; our Garmin Striker 4 review covers it in detail.
- You fish from shore or a kayak with no mount: the Garmin Striker Cast, which shows sonar on your phone. Skip it if you want a dedicated screen on the boat.

Frequently Asked Questions
Does the Garmin Striker have preloaded maps?
Not the Striker Vivid 5cv. Garmin lists Quickdraw Contours as its only map support, so you record your own 1 ft contours as you drive.
Do the Garmin Striker and Humminbird HELIX both have GPS?
Yes, both units in this comparison have built-in GPS. Garmin lists 5,000 waypoints and 100 routes for the Striker Vivid 5cv; the HELIX 5 listing describes GPS navigation and its basemap but does not give a waypoint count.
Does the Humminbird HELIX 5 have down imaging?
Not the HELIX 5 CHIRP GPS G3; its listing names Dual Spectrum CHIRP sonar and no imaging view. In the HELIX listings we read, imaging models name it in the title (MEGA Down Imaging or MEGA Side Imaging), so check the model name and the transducer in the box.
Can I use a Garmin Striker or a Humminbird HELIX on a kayak?
The Garmin has a documented path through the optional kayak in-hull mount described above. The HELIX 5 listing names only a transom-mount transducer, so confirm a kayak mounting option with Humminbird or your dealer first.
