The catch
Lowrance Eagle 9 TripleShot HD
For SideScan to work, the transducer needs a clear mounting spot and a suitable boat speed.
Side by side
Lowrance Eagle 9 TripleShot HD vs Garmin STRIKER Vivid 9sv Compared: Chart cards and extra pixels come with Eagle, while Garmin records Quickdraw contours
Quick verdict
Take the Lowrance for chart cards and extra pixels, or the Garmin for Quickdraw.
Before you buy
Why, and what it costs you
Actual screen area, given the published aspect ratio
Display area comes to about 35.3 square inches on Eagle 9 TripleShot HD and about 35.7 on STRIKER Vivid 9sv. That helps when 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 9 TripleShot HD
- Why pick it
- Supported C-MAP chart cards are a requirement
- Its TripleShot HD sonar setup suits the way you fish
- The catch
- For SideScan to work, the transducer needs a clear mounting spot and a suitable boat speed.
Garmin STRIKER Vivid 9sv
- Why pick it
- Garmin Quickdraw and SideVü appeal to you
- The GT52HW-TM sonar in the selected US bundle suits how you fish

What this page compares
Eagle 9 TripleShot HD and STRIKER Vivid 9sv side by side on included sonar, display workspace, chart support and the battery demands of your boat.
Take the Lowrance for chart cards and extra pixels, or the Garmin for Quickdraw.
Which one fits
Pick the situations that sound like you
Reading sonar while sitting in the usual position
The diagonal is nine-inch on both, and both include side-imaging transducers. Pixels differ though, with 1024 × 600 on Eagle 9 and 800 × 480 on STRIKER Vivid 9sv, so matching diagonals do not give matching pixel workspace.

Picking a setup around maps and a small battery
Garmin records your own Quickdraw contours and waypoints, yet it takes no navigation chart cards. Eagle supports compatible C-MAP cards, so confirm the card’s actual water coverage before buying it.

At 287.2mm and 282mm the cases are close in width. Check how the bracket swings, where cables exit and whether the transducer has a clear view to both sides.

On a two-pane screen, it is 512 versus 400 columns per pane
An even split of the nominal pixel width gives Eagle 512 columns per pane and Garmin 400. Vertically, Eagle also has 600 pixels versus 480.

In practice
Differences you will notice
Actual screen area, given the published aspect ratio
Display area comes to about 35.3 square inches on Eagle 9 TripleShot HD and about 35.7 on STRIKER Vivid 9sv. That helps when 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, you get about 13.3 hours at the published electrical point of Eagle 9 TripleShot HD and 11.4 hours at the point for STRIKER Vivid 9sv.
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 0.64A ×12V =7.7W 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.
On a two-pane screen, it is 512 versus 400 columns per pane
An even split of the nominal pixel width gives Eagle 512 columns per pane and Garmin 400. Vertically, Eagle also has 600 pixels versus 480.
How we worked this out
1024 ÷ 2 = 512 and 800 ÷ 2 = 400. Dividers, labels and software layout are left out of this idealized split, and it is not a sonar-resolution measurement.

Spec by spec
Where they really differ
| Spec | Lowrance Eagle 9 TripleShot HD | Garmin STRIKER Vivid 9sv | In practice |
|---|---|---|---|
| Pixel matrix | 1024 × 600 | 800 × 480 | It governs addressable display workspace and has no bearing on acoustic target separation. |
| Display technology | IPS | WVGA color | Check how it looks off-axis and through your polarized glasses. |
| Published electrical point | 0.64A 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 | 287.2mm | 282mm | Allow extra room for the bracket and the cable exits. |
Trade-offs
What each pick costs you
With Lowrance Eagle 9 TripleShot HD
- The base transducer bundle is the package picked here, and a C-MAP DISCOVER card is its own named package. Verify the regional charts that come with it and the exact lake.
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
Supported C-MAP chart cards are a requirement
Go with Lowrance Eagle 9 TripleShot HD. The diagonal is nine-inch on both, and both include side-imaging transducers. Pixels differ though, with 1024 × 600 on Eagle 9 and 800 × 480 on STRIKER Vivid 9sv, so matching diagonals do not give matching pixel workspace.
Garmin Quickdraw and SideVü appeal to you
Go with Garmin STRIKER Vivid 9sv. Garmin records your own Quickdraw contours and waypoints, yet it takes no navigation chart cards. Eagle supports compatible C-MAP cards, so confirm the card’s actual water coverage before buying it.
Decision guide
How to decide
Chart-card support and more pixels favor Lowrance. Quickdraw favors Garmin.
Screen and sonar bundle are separate questions
The diagonal is nine-inch on both, and both include side-imaging transducers. Pixels differ though, with 1024 × 600 on Eagle 9 and 800 × 480 on STRIKER Vivid 9sv, so matching diagonals do not give matching pixel workspace.
Decide on maps and electrical needs
Garmin records your own Quickdraw contours and waypoints, yet it takes no navigation chart cards. Eagle supports compatible C-MAP cards, so confirm the card’s actual water coverage before buying it.
Look at installation and future expansion
At 287.2mm and 282mm the cases are close in width. Check how the bracket swings, where cables exit and whether the transducer has a clear view to both sides.
What this page can’t tell you
- The comparison rests on manufacturer specifications and was not tested on the water.
- Neither screen pixels nor contour spacing tell you how accurate the sonar or depth readings are.
- For chart cards, mounting accessories and networked live sonar, verify compatibility against the exact model.
