Head-to-head
Garmin STRIKER Vivid 9sv vs Humminbird HELIX 5 CHIRP DI GPS G3: Garmin enlarges side views, HELIX fits compact chart-card navigation
The short answer
Choose a large side-imaging display or compact chart-card navigation.
Before you choose
The reasoning and the trade-offs
Physical screen area at the published aspect ratio
STRIKER Vivid 9sv provides about 35.7 square inches of display area and HELIX 5 CHIRP DI 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.

Winner by situation
Start with what you need it to do
Reading sonar from the normal seated position
Garmin’s nine-inch SideVü package and HELIX’s five-inch Down Imaging package solve different sonar tasks. The Garmin covers both sides, while this HELIX model does not.

Reusing hardware or expanding the boat system
Both displays have 800 ×480 pixels. Garmin’s increase in viewing area can improve visibility from a larger cockpit, while the HELIX is easier to place close to a kayak seat.

What matters in practice
The differences that matter
Physical screen area at the published aspect ratio
STRIKER Vivid 9sv provides about 35.7 square inches of display area and HELIX 5 CHIRP DI 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 11.4 hours at the STRIKER Vivid 9sv published electrical point and 13.9 hours at the HELIX 5 CHIRP DI 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 0.75A ×12V =9W 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.
The larger diagonal provides 3.24 times the viewing area
At the same pixel aspect ratio, a nine-inch display has 3.24 times the area of a five-inch display. Both still have 384000 pixels.
How we reached this conclusion
9² ÷5² =3.24.800 ×480 =384000. This describes physical presentation, not fish-detection accuracy.

Meaningful differences
What changes the fit
| What changes | Garmin STRIKER Vivid 9sv | Humminbird HELIX 5 CHIRP DI GPS G3 | Why it matters |
|---|---|---|---|
| Display diagonal | 9 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 | 0.75A at 12V | 0.615A at 12V | Use the stated conditions when sizing a battery. HELIX voltage is a nominal 12V assumption. |
| Included transducer | GT52HW-TM in the selected US bundle | XNT 9 HW DI T | This exact bundle determines the supplied sonar modes and installation hardware. |
| Side imaging | Included | Not included | A below-boat image does not replace a left-right structure scan. |
| 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 9sv
- It offers custom contour mapping but not a detailed preloaded lake-chart package.
If you choose Humminbird HELIX 5 CHIRP DI GPS G3
- The five-inch screen gets busy when chart and Down Imaging are split.
Recommendation switch
The decision flips if...
You need included SideVü on a nine-inch display
Choose Garmin STRIKER Vivid 9sv. Garmin’s nine-inch SideVü package and HELIX’s five-inch Down Imaging package solve different sonar tasks. The Garmin covers both sides, while this HELIX model does not.
You want supported charts in the compact HELIX system
Choose Humminbird HELIX 5 CHIRP DI GPS G3. HELIX accepts listed chart cards. STRIKER’s Quickdraw and waypoint functions do not add a navigation-chart slot, despite its larger screen.
What matters in practice
How to make the call
Separate the screen from the sonar bundle
Garmin’s nine-inch SideVü package and HELIX’s five-inch Down Imaging package solve different sonar tasks. The Garmin covers both sides, while this HELIX model does not.
Choose the maps and electrical plan
HELIX accepts listed chart cards. STRIKER’s Quickdraw and waypoint functions do not add a navigation-chart slot, despite its larger screen.
Check the installation and future system
Both displays have 800 ×480 pixels. Garmin’s increase in viewing area can improve visibility from a larger cockpit, while the HELIX is easier to place close to a kayak seat.
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.
