Side by side
Garmin STRIKER Vivid 7cv vs Humminbird HELIX 5 CHIRP GPS G3 Compared: Garmin gives downward sonar a bigger view, HELIX supports navigation with chart cards
Quick verdict
It is a larger DownVü display against a compact chart-card plotter.
Before you buy
Why, and what it costs you
Actual screen area, given the published aspect ratio
STRIKER Vivid 7cv gives about 21.6 square inches of display area, against about 11 for HELIX 5 CHIRP GPS G3. The figures help in judging viewing distance and split-screen comfort.
Where this comes from
Assuming square pixels and the published diagonal, Area = diagonal² × horizontal pixels × vertical pixels ÷ (horizontal pixels² + vertical pixels²). The values are geometric estimates and not active-area measurements.
The catch
Humminbird HELIX 5 CHIRP GPS G3
Down Imaging and Side Imaging are not offered.
Garmin STRIKER Vivid 7cv
- Why pick it
- ClearVü and a seven-inch screen appeal to you
- The GT20-TM sonar in the selected US bundle suits how you fish
- The catch
- SideVu is not available from the transducer in the box.
Humminbird HELIX 5 CHIRP GPS G3
- Why pick it
- Supported LakeMaster or CoastMaster charts are a requirement
- The XNT 9 HW T sonar setup is right for your fishing

It is a larger DownVü display against a compact chart-card plotter.
Which one fits
Pick the situations that sound like you
Reading sonar while sitting in the usual position
ClearVü downward imaging comes in the Garmin bundle. The selected HELIX 5 CHIRP GPS G3 has Dual Spectrum CHIRP but not the DI suffix, which gives it a different sonar scope.

Picking a setup around maps and a small battery
Supported chart cards work in HELIX. Garmin’s STRIKER keeps GPS positions and Quickdraw contours but has no chart-card slot, so GPS by itself does not decide the navigation question.

In practice
Differences you will notice
Actual screen area, given the published aspect ratio
STRIKER Vivid 7cv gives about 21.6 square inches of display area, against about 11 for HELIX 5 CHIRP GPS G3. The figures help in judging viewing distance and split-screen comfort.
How we worked this out
Assuming square pixels and the published diagonal, Area = diagonal² × horizontal pixels × vertical pixels ÷ (horizontal pixels² + vertical pixels²). The values are geometric estimates and not active-area measurements.
A 12.8V10Ah battery, keeping 20% in reserve
Working from the 102.4Wh allowance, the published electrical point of STRIKER Vivid 7cv works out to about 15.5 hours and the HELIX 5 CHIRP GPS G3 point to 13.9 hours.
How we worked this out
The assumption is 12.8V ×10Ah ×0.8 =102.4Wh usable for this device alone. At the published points, power is 0.55A ×12V =6.6W and 0.615A ×12V =7.4W. HELIX input is taken as 12V, since the draw specification leaves out the test voltage. Converter loss, temperature and battery aging are ignored. This is not a measured runtime comparison.
The purchase plan changes if you own one LakeMaster card
A compatible LakeMaster card works in HELIX. STRIKER has zero chart-card slots, so the card you already have cannot be part of that setup.
How we worked this out
The requirement is one supported LakeMaster card slot. HELIX lists LakeMaster compatibility and one microSD slot, while STRIKER has no chart-card capability. Verify the card generation.

Spec by spec
Where they really differ
| Spec | Garmin STRIKER Vivid 7cv | Humminbird HELIX 5 CHIRP GPS G3 | In practice |
|---|---|---|---|
| Display diagonal | 7 inches | 5 inches | A bigger physical view helps if the unit is mounted farther from the seat. |
| Display technology | WVGA color | Color TFT | Check how it looks off-axis and through your polarized glasses. |
| Published electrical point | 0.55A at 12V | 0.615A at 12V | Size a battery using the stated conditions. The HELIX voltage is a nominal 12V assumption. |
| Included transducer | GT20-TM in the selected US bundle | XNT 9 HW T | The sonar modes and installation hardware you get depend on this exact bundle. |
| Downward imaging | Included | Not included | The suffix, DI, cv or SplitShot, needs checking. |
| Chart-card path | No chart-card support | LakeMaster, CoastMaster and listed Navionics cards | Navigation chart cards are a different thing from GPS waypoints and self-recorded depth maps. |
| Personal mapping | Quickdraw Contours, 1ft contours | AutoChart Live, depth plus bottom hardness and vegetation | Fit the layers and contour display you need to the fishing task. |
Trade-offs
What each pick costs you
With Garmin STRIKER Vivid 7cv
- No detailed chart bundle comes preloaded.
With Humminbird HELIX 5 CHIRP GPS G3
- Because the G3 head does not network, it cannot be expanded into MEGA Live or a shared-display network.
Change of plan
When the answer changes
ClearVü and a seven-inch screen appeal to you
Go with Garmin STRIKER Vivid 7cv. ClearVü downward imaging comes in the Garmin bundle. The selected HELIX 5 CHIRP GPS G3 has Dual Spectrum CHIRP but not the DI suffix, which gives it a different sonar scope.
Supported LakeMaster or CoastMaster charts are a requirement
Go with Humminbird HELIX 5 CHIRP GPS G3. Supported chart cards work in HELIX. Garmin’s STRIKER keeps GPS positions and Quickdraw contours but has no chart-card slot, so GPS by itself does not decide the navigation question.
Decision guide
How to decide
Take the larger DownVü display, or take the compact chart-card plotter.
Sonar bundle first, then the screen
ClearVü downward imaging comes in the Garmin bundle. The selected HELIX 5 CHIRP GPS G3 has Dual Spectrum CHIRP but not the DI suffix, which gives it a different sonar scope.
Decide how you will map and power it
Supported chart cards work in HELIX. Garmin’s STRIKER keeps GPS positions and Quickdraw contours but has no chart-card slot, so GPS by itself does not decide the navigation question.
Fitting it now and upgrading later
Both use 800 × 480 pixels even though the Garmin display is larger. Before deciding whether compact placement or larger labels count for more, sit at the viewing distance you intend to use.
What this page can’t tell you
- These comparisons rest only on manufacturer specifications. None was tested on the water.
- Accuracy of the sonar and the depth is not something pixels or contour spacing can establish.
- Chart cards, mounting accessories and networked live sonar all call for a compatibility check against the exact model.
