The catch
Lowrance Eagle 7 TripleShot HD
This is not a platform for networked live sonar.
Side by side
Lowrance Eagle 7 TripleShot HD vs Garmin STRIKER Vivid 9sv Compared: Eagle packs charts into a smaller body, Garmin makes the side-imaging view larger
Quick verdict
It is a smaller unit that can use charts against a larger Garmin side-imaging view.
Before you buy
Why, and what it costs you
Actual screen area, given the published aspect ratio
Eagle 7 TripleShot HD gives about 21.6 square inches of display area and STRIKER Vivid 9sv about 35.7, which helps 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
Garmin STRIKER Vivid 9sv
A narrow kayak console is a tight fit for a unit this large.
Lowrance Eagle 7 TripleShot HD
- Why pick it
- Chart cards have to fit a narrower console space
- Its TripleShot HD sonar setup suits the way you fish
- The catch
- This is not a platform for networked live sonar.
Garmin STRIKER Vivid 9sv
- Why pick it
- A nine-inch display and Quickdraw are your preference
- The GT52HW-TM sonar in the selected US bundle fits how you fish
- The catch
- A narrow kayak console is a tight fit for a unit this large.

It is a smaller unit that can use charts against a larger Garmin side-imaging view.
Which one fits
Pick the situations that sound like you
Reading sonar while sitting in the usual position
Side imaging comes with both, and Eagle 7 is the physically smaller one. Garmin’s nine-inch display has the same 800 × 480 pixel matrix, so you gain viewing area. The pixel count stays the same.

In practice
Differences you will notice
Actual screen area, given the published aspect ratio
Eagle 7 TripleShot HD gives about 21.6 square inches of display area and STRIKER Vivid 9sv about 35.7, which helps 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
Using the 102.4Wh working allowance, the published electrical point of Eagle 7 TripleShot HD works out to about 15.5 hours and the STRIKER Vivid 9sv point to about 11.4 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 0.75A ×12V =9W. 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 Garmin body is ruled out by a 250mm console width
Eagle 7 has 24.1mm to spare within 250mm. Vivid 9sv is 282mm wide, 32mm over.
How we worked this out
250 minus 225.9 =24.1mm. 250 minus 282 =negative 32mm. Brackets and cables are left out.

Spec by spec
Where they really differ
| Spec | Lowrance Eagle 7 TripleShot HD | Garmin STRIKER Vivid 9sv | In practice |
|---|---|---|---|
| Display diagonal | 7 inches | 9 inches | A bigger physical view helps if the unit is mounted farther from the seat. |
| Display technology | IPS | WVGA color | Check how it looks off-axis and through your polarized glasses. |
| Published electrical point | 0.55A at 12V | 0.75A at 12V | Size a battery using the stated conditions. The HELIX voltage is a nominal 12V assumption. |
| Included transducer | TripleShot HD | GT52HW-TM in the selected US bundle | The sonar modes and installation hardware you get depend on this exact bundle. |
| Chart-card path | C-MAP chart-card support | No chart-card support | Navigation chart cards are a different thing from GPS waypoints and self-recorded depth maps. |
| Personal mapping | Genesis Live, 0.5ft contours | Quickdraw Contours, 1ft contours | Fit the layers and contour display you need to the fishing task. |
| Bare body width | 225.9mm | 282mm | Allow extra room for the bracket and the cable exits. |
Trade-offs
What each pick costs you
With Lowrance Eagle 7 TripleShot HD
- What charts you get depends on the exact US bundle, since the Eagle name alone does not settle it.
With Garmin STRIKER Vivid 9sv
- Custom contour mapping is there, but a detailed preloaded lake-chart package is not.
Change of plan
When the answer changes
Chart cards have to fit a narrower console space
Go with Lowrance Eagle 7 TripleShot HD. Side imaging comes with both, and Eagle 7 is the physically smaller one. Garmin’s nine-inch display has the same 800 × 480 pixel matrix, so you gain viewing area. The pixel count stays the same.
A nine-inch display and Quickdraw are your preference
Go with Garmin STRIKER Vivid 9sv. C-MAP chart cards work in the Eagle. Garmin’s STRIKER stores waypoints and the Quickdraw contours it generates itself, but it does not accept navigation-chart cards.
Decision guide
How to decide
Either a smaller unit that handles charts or a larger Garmin side-imaging view.
Separating the screen from the sonar bundle
Side imaging comes with both, and Eagle 7 is the physically smaller one. Garmin’s nine-inch display has the same 800 × 480 pixel matrix, so you gain viewing area. The pixel count stays the same.
Settling maps and the electrical plan
C-MAP chart cards work in the Eagle. Garmin’s STRIKER stores waypoints and the Quickdraw contours it generates itself, but it does not accept navigation-chart cards.
Installation and future growth
A 56.1mm width gap separates the two cases. On a small boat, the space the display takes can matter more than getting the largest diagonal.
What this page can’t tell you
- The comparisons draw on manufacturer specifications and involve no on-water testing.
- Neither screen pixels nor contour spacing establish sonar or depth accuracy.
- Compatibility with the exact model has to be checked for chart cards, mounting accessories and networked live sonar.
