Main trade-off
Lowrance Eagle 9 TripleShot HD
SideScan needs unobstructed transducer placement and a suitable boat speed.
Head-to-head
Lowrance Eagle 9 TripleShot HD vs Lowrance Eagle 7 SplitShot HD: Nine-inch adds side imaging, seven-inch keeps below-boat work narrower
The short answer
Choose the larger side-imaging package or keep the narrower downward-sonar unit.
Before you choose
The reasoning and the trade-offs
Physical screen area at the published aspect ratio
Eagle 9 TripleShot HD provides about 35.3 square inches of display area and Eagle 7 SplitShot HD about 21.6. 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

Winner by situation
Start with what you need it to do
Reading sonar from the normal seated position
Eagle 9 TripleShot adds SideScan and a higher pixel matrix. Eagle 7 SplitShot provides CHIRP and DownScan, so the choice is more than two inches of screen.

Choosing a map and small-battery setup
Both use the same C-MAP and Genesis Live family. The larger model does not create a different chart ecosystem or a general Ethernet expansion path.

Reusing hardware or expanding the boat system
The 9-inch case is 61.3mm wider. A limited console may favor Eagle 7 even if its selected transducer gives up side views.

What matters in practice
The differences that matter
Physical screen area at the published aspect ratio
Eagle 9 TripleShot HD provides about 35.3 square inches of display area and Eagle 7 SplitShot HD about 21.6. 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 13.3 hours at the Eagle 9 TripleShot HD published electrical point and 15.5 hours at the Eagle 7 SplitShot HD point.
How we reached this conclusion
Assume 12.8V ×10Ah ×0.8 =102.4Wh usable for this device alone. Published-point power is 0.64A ×12V =7.7W and 0.55A ×12V =6.6W. 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 280mm body-width limit excludes Eagle 9
Eagle 9 is 287.2mm wide, exceeding 280mm by 7.2mm. Eagle 7 leaves 54.1mm before mounting clearances.
How we reached this conclusion
280 minus 287.2 =negative 7.2mm.280 minus 225.9 =54.1mm. A close body fit still needs bracket and connector clearance.

Meaningful differences
What changes the fit
| What changes | Lowrance Eagle 9 TripleShot HD | Lowrance Eagle 7 SplitShot HD | Why it matters |
|---|---|---|---|
| Display diagonal | 9 inches | 7 inches | Larger physical views help when the unit sits farther from the seat. |
| Pixel matrix | 1024 × 600 | 800 × 480 | This controls addressable display workspace, not acoustic target separation. |
| Published electrical point | 0.64A at 12V | 0.55A at 12V | Use the stated conditions when sizing a battery. HELIX voltage is a nominal 12V assumption. |
| Included transducer | TripleShot HD | SplitShot HD | 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. |
| Bare body width | 287.2mm | 225.9mm | Leave additional room for the bracket and cable exits. |
What you give up
Every choice has a cost
If you choose Lowrance Eagle 9 TripleShot HD

Recommendation switch
The decision flips if...
You need SideScan and 1024 ×600 pixels
Choose Lowrance Eagle 9 TripleShot HD. Eagle 9 TripleShot adds SideScan and a higher pixel matrix. Eagle 7 SplitShot provides CHIRP and DownScan, so the choice is more than two inches of screen.
You prefer a narrower case for below-boat fishing
Choose Lowrance Eagle 7 SplitShot HD. Both use the same C-MAP and Genesis Live family. The larger model does not create a different chart ecosystem or a general Ethernet expansion path.
What matters in practice
How to make the call
Separate the screen from the sonar bundle
Eagle 9 TripleShot adds SideScan and a higher pixel matrix. Eagle 7 SplitShot provides CHIRP and DownScan, so the choice is more than two inches of screen.
Choose the maps and electrical plan
Both use the same C-MAP and Genesis Live family. The larger model does not create a different chart ecosystem or a general Ethernet expansion path.
Check the installation and future system
The 9-inch case is 61.3mm wider. A limited console may favor Eagle 7 even if its selected transducer gives up side views.
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.
