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 Humminbird HELIX 5 CHIRP DI GPS G3: Eagle scans to the sides, HELIX keeps downward imaging and charts compact
The short answer
Choose broad side-imaging views or the compact HELIX chart and Down Imaging setup.
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 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.
Main trade-off
Humminbird HELIX 5 CHIRP DI GPS G3

Winner by situation
Start with what you need it to do
Reading sonar from the normal seated position
Eagle 9 supplies side imaging as well as DownScan. The selected HELIX 5 DI bundle provides Down Imaging, but it does not become a side-imaging unit because it has GPS.

Choosing a map and small-battery setup
HELIX supports LakeMaster and CoastMaster within the listed card compatibility. Eagle uses the C-MAP path. Check the specific lake and card generation rather than ranking maps by brand.

Reusing hardware or expanding the boat system
HELIX 5 G3 lacks MEGA Live and Ethernet compatibility in its specification. The Eagle 9 TripleShot HD package also should not be bought as a generic networked-live-sonar upgrade base.

A left-right scan requirement separates the supplied bundles
Eagle 9 supplies both side-looking views. HELIX 5 DI supplies zero side-looking views in this bundle, so it fails that requirement without switching to a different supported system.

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 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 13.3 hours at the Eagle 9 TripleShot HD 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 0.64A ×12V =7.7W 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.
A left-right scan requirement separates the supplied bundles
Eagle 9 supplies both side-looking views. HELIX 5 DI supplies zero side-looking views in this bundle, so it fails that requirement without switching to a different supported system.
How we reached this conclusion
Required coverage is left plus right side imaging. Compare included TripleShot HD with the HELIX DI transducer and the exact head-unit sonar capabilities.

Meaningful differences
What changes the fit
| What changes | Lowrance Eagle 9 TripleShot HD | 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. |
| Pixel matrix | 1024 × 600 | 800 × 480 | This controls addressable display workspace, not acoustic target separation. |
| Display technology | IPS | Color TFT | Check off-axis visibility and your polarized glasses. |
| Published electrical point | 0.64A at 12V | 0.615A at 12V | Use the stated conditions when sizing a battery. HELIX voltage is a nominal 12V assumption. |
| Included transducer | TripleShot HD | 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 | C-MAP chart-card support | LakeMaster, CoastMaster and listed Navionics cards | GPS waypoints and self-recorded depth maps are different from navigation chart cards. |
| Personal mapping | Genesis Live, 0.5ft 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 Lowrance Eagle 9 TripleShot HD
- This selected package is the base transducer bundle. A C-MAP DISCOVER card is a separate named package. Verify included regional charts and the exact lake.
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 SideScan and a larger display
Choose Lowrance Eagle 9 TripleShot HD. Eagle 9 supplies side imaging as well as DownScan. The selected HELIX 5 DI bundle provides Down Imaging, but it does not become a side-imaging unit because it has GPS.
You prefer Humminbird maps and a five-inch display
Choose Humminbird HELIX 5 CHIRP DI GPS G3. HELIX supports LakeMaster and CoastMaster within the listed card compatibility. Eagle uses the C-MAP path. Check the specific lake and card generation rather than ranking maps by brand.
What matters in practice
How to make the call
Separate the screen from the sonar bundle
Eagle 9 supplies side imaging as well as DownScan. The selected HELIX 5 DI bundle provides Down Imaging, but it does not become a side-imaging unit because it has GPS.
Choose the maps and electrical plan
HELIX supports LakeMaster and CoastMaster within the listed card compatibility. Eagle uses the C-MAP path. Check the specific lake and card generation rather than ranking maps by brand.
Check the installation and future system
HELIX 5 G3 lacks MEGA Live and Ethernet compatibility in its specification. The Eagle 9 TripleShot HD package also should not be bought as a generic networked-live-sonar upgrade base.
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.
