Head-to-head
Lowrance Eagle 7 TripleShot HD vs Garmin STRIKER Vivid 9sv: Eagle fits charts in a smaller body, Garmin enlarges the side-imaging view
The short answer
Choose a smaller chart-capable unit or a larger Garmin side-imaging view.
Before you choose
The reasoning and the trade-offs
Physical screen area at the published aspect ratio
Eagle 7 TripleShot HD provides about 21.6 square inches of display area and STRIKER Vivid 9sv about 35.7. 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
Garmin STRIKER Vivid 9sv
It is physically large for a narrow kayak console.

Winner by situation
Start with what you need it to do
Reading sonar from the normal seated position
Both provide side imaging, but Eagle 7 is physically smaller. Garmin’s nine-inch display still has the same 800 ×480 pixel matrix, so the gain is viewing area rather than pixel count.

Choosing a map and small-battery setup

What matters in practice
The differences that matter
Physical screen area at the published aspect ratio
Eagle 7 TripleShot HD provides about 21.6 square inches of display area and STRIKER Vivid 9sv about 35.7. 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 Eagle 7 TripleShot HD published electrical point and 11.4 hours at the STRIKER Vivid 9sv 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 0.75A ×12V =9W. 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.
A 250mm console width rules out the Garmin body
Eagle 7 leaves 24.1mm within 250mm. Vivid 9sv is 282mm wide and exceeds it by 32mm.
How we reached this conclusion
250 minus 225.9 =24.1mm.250 minus 282 =negative 32mm. Brackets and cables are not included.

Meaningful differences
What changes the fit
| What changes | Lowrance Eagle 7 TripleShot HD | Garmin STRIKER Vivid 9sv | Why it matters |
|---|---|---|---|
| Display diagonal | 7 inches | 9 inches | Larger physical views help when the unit sits farther from the seat. |
| Display technology | IPS | WVGA color | Check off-axis visibility and your polarized glasses. |
| Published electrical point | 0.55A at 12V | 0.75A at 12V | Use the stated conditions when sizing a battery. HELIX voltage is a nominal 12V assumption. |
| Included transducer | TripleShot HD | GT52HW-TM in the selected US bundle | This exact bundle determines the supplied sonar modes and installation hardware. |
| Chart-card path | C-MAP chart-card support | No chart-card support | GPS waypoints and self-recorded depth maps are different from navigation chart cards. |
| Personal mapping | Genesis Live, 0.5ft contours | Quickdraw Contours, 1ft contours | Match the required layers and contour display to the fishing task. |
| Bare body width | 225.9mm | 282mm | Leave additional room for the bracket and cable exits. |
What you give up
Every choice has a cost
If you choose Lowrance Eagle 7 TripleShot HD
- Chart coverage still depends on the exact US bundle, not the Eagle name alone.
If you choose Garmin STRIKER Vivid 9sv
- It offers custom contour mapping but not a detailed preloaded lake-chart package.
Recommendation switch
The decision flips if...
You need chart cards in a narrower console space
Choose Lowrance Eagle 7 TripleShot HD. Both provide side imaging, but Eagle 7 is physically smaller. Garmin’s nine-inch display still has the same 800 ×480 pixel matrix, so the gain is viewing area rather than pixel count.
You prefer a nine-inch display and Quickdraw
Choose Garmin STRIKER Vivid 9sv. The Eagle accepts C-MAP chart cards. Garmin’s STRIKER stores waypoints and self-generated Quickdraw contours without accepting navigation-chart cards.
What matters in practice
How to make the call
Separate the screen from the sonar bundle
Both provide side imaging, but Eagle 7 is physically smaller. Garmin’s nine-inch display still has the same 800 ×480 pixel matrix, so the gain is viewing area rather than pixel count.
Choose the maps and electrical plan
The Eagle accepts C-MAP chart cards. Garmin’s STRIKER stores waypoints and self-generated Quickdraw contours without accepting navigation-chart cards.
Check the installation and future system
The cases differ by 56.1mm in width. On a small boat, space for the display may matter more than the largest diagonal available.
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.
