Head-to-head
Garmin STRIKER Vivid 7cv vs Humminbird HELIX 5 CHIRP GPS G3: Garmin enlarges downward sonar, HELIX supports chart-card navigation
The short answer
Choose a larger DownVü display or a compact chart-card plotter.
Before you choose
The reasoning and the trade-offs
Physical screen area at the published aspect ratio
STRIKER Vivid 7cv provides about 21.6 square inches of display area and HELIX 5 CHIRP GPS G3 about 11. This helps judge viewing distance and split-screen comfort.
What this is based on
Area = diagonal² × horizontal pixels × vertical pixels ÷ (horizontal pixels² + vertical pixels²), assuming square pixels and the published diagonal. Values are geometric estimates, not active-area measurements.
Main trade-off
Humminbird HELIX 5 CHIRP GPS G3
It has no Down Imaging or Side Imaging.

Winner by situation
Start with what you need it to do
Reading sonar from the normal seated position
The Garmin bundle includes ClearVü downward imaging. The selected HELIX 5 CHIRP GPS G3 has Dual Spectrum CHIRP without the DI suffix, so its sonar scope is different.

Choosing a map and small-battery setup
HELIX accepts supported chart cards. Garmin’s STRIKER stores GPS positions and Quickdraw contours but has no chart-card slot. GPS alone is not the deciding navigation feature.

Reusing hardware or expanding the boat system
The Garmin display is larger, but both use 800 ×480 pixels. Sit at the intended viewing distance before deciding whether compact placement or larger labels matter more.

Need to use an existing compatible LakeMaster chart card
HELIX can use a compatible LakeMaster card. STRIKER has zero chart-card slots, so the existing card cannot be part of that setup.

What matters in practice
The differences that matter
Physical screen area at the published aspect ratio
STRIKER Vivid 7cv provides about 21.6 square inches of display area and HELIX 5 CHIRP GPS G3 about 11. This helps judge viewing distance and split-screen comfort.
How we reached this conclusion
Area = diagonal² × horizontal pixels × vertical pixels ÷ (horizontal pixels² + vertical pixels²), assuming square pixels and the published diagonal. Values are geometric estimates, not active-area measurements.
A 12.8V10Ah battery with 20% held in reserve
The 102.4Wh working allowance gives about 15.5 hours at the STRIKER Vivid 7cv published electrical point and 13.9 hours at the HELIX 5 CHIRP GPS G3 point.
How we reached this conclusion
Assume 12.8V ×10Ah ×0.8 =102.4Wh usable for this device alone. Published-point power is 0.55A ×12V =6.6W and 0.615A ×12V =7.4W. HELIX input is assumed 12V because the draw specification omits test voltage. Ignore converter loss, temperature and battery aging. This is not a measured runtime comparison.
Owning one LakeMaster card changes the purchase plan
HELIX can use a compatible LakeMaster card. STRIKER has zero chart-card slots, so the existing card cannot be part of that setup.
How we reached this conclusion
Requirement is one supported LakeMaster card slot. HELIX lists LakeMaster compatibility and one microSD slot. STRIKER’s chart-card capability is absent. Verify the card generation.

Meaningful differences
What changes the fit
| What changes | Garmin STRIKER Vivid 7cv | Humminbird HELIX 5 CHIRP GPS G3 | Why it matters |
|---|---|---|---|
| Display diagonal | 7 inches | 5 inches | Larger physical views help when the unit sits farther from the seat. |
| Display technology | WVGA color | Color TFT | Check off-axis visibility and your polarized glasses. |
| Published electrical point | 0.55A at 12V | 0.615A at 12V | Use the stated conditions when sizing a battery. HELIX voltage is a nominal 12V assumption. |
| Included transducer | GT20-TM in the selected US bundle | XNT 9 HW T | This exact bundle determines the supplied sonar modes and installation hardware. |
| Downward imaging | Included | Not included | Check the exact DI, cv or SplitShot suffix. |
| Chart-card path | No chart-card support | LakeMaster, CoastMaster and listed Navionics cards | GPS waypoints and self-recorded depth maps are different from navigation chart cards. |
| Personal mapping | Quickdraw Contours, 1ft contours | AutoChart Live, depth plus bottom hardness and vegetation | Match the required layers and contour display to the fishing task. |
What you give up
Every choice has a cost
If you choose Garmin STRIKER Vivid 7cv
- It lacks a preloaded detailed chart bundle.
If you choose Humminbird HELIX 5 CHIRP GPS G3
- The non-networking G3 head cannot grow into MEGA Live or a shared-display network.
Recommendation switch
The decision flips if...
You want ClearVü and a seven-inch screen
Choose Garmin STRIKER Vivid 7cv. The Garmin bundle includes ClearVü downward imaging. The selected HELIX 5 CHIRP GPS G3 has Dual Spectrum CHIRP without the DI suffix, so its sonar scope is different.
You need supported LakeMaster or CoastMaster charts
Choose Humminbird HELIX 5 CHIRP GPS G3. HELIX accepts supported chart cards. Garmin’s STRIKER stores GPS positions and Quickdraw contours but has no chart-card slot. GPS alone is not the deciding navigation feature.
What matters in practice
How to make the call
Separate the screen from the sonar bundle
The Garmin bundle includes ClearVü downward imaging. The selected HELIX 5 CHIRP GPS G3 has Dual Spectrum CHIRP without the DI suffix, so its sonar scope is different.
Choose the maps and electrical plan
HELIX accepts supported chart cards. Garmin’s STRIKER stores GPS positions and Quickdraw contours but has no chart-card slot. GPS alone is not the deciding navigation feature.
Check the installation and future system
The Garmin display is larger, but both use 800 ×480 pixels. Sit at the intended viewing distance before deciding whether compact placement or larger labels matter more.
What this comparison cannot tell you
- These are manufacturer-specification comparisons without on-water testing.
- Screen pixels and contour spacing do not establish sonar or depth accuracy.
- Chart cards, mounting accessories and networked live sonar require exact model compatibility checks.
