Head-to-head
Garmin STRIKER 4 vs Lowrance Eagle 7 SplitShot HD: Eagle adds charts and a larger view, STRIKER fits narrower mounting space
The short answer
Choose STRIKER 4 when a narrow display and basic sonar with GPS waypoints cover the trip. Choose Eagle 7 SplitShot HD when the boat needs a larger screen, DownScan and supported detailed charts. Measure the mounting space and include the electrical supply and transducer installation in either plan.
Before you choose
The reasoning and the trade-offs
A narrow helm can reject the larger display before purchase
The Eagle body is 134.9 mm wider than STRIKER 4 using the published widths.
What this is based on
The published head-unit widths are 225.9 mm for Eagle and 91 mm for STRIKER 4. Their difference is 134.9 mm, and the example opening is 120 mm before bracket or cable allowances.

What matters in practice
The differences that matter
A narrow helm can reject the larger display before purchase
The Eagle body is 134.9 mm wider than STRIKER 4 using the published widths.
How we reached this conclusion
The published head-unit widths are 225.9 mm for Eagle and 91 mm for STRIKER 4. Their difference is 134.9 mm, and the example opening is 120 mm before bracket or cable allowances.
GPS waypoints and detailed charts serve different jobs
STRIKER 4 can mark locations, while Eagle can use supported detailed C-MAP charts.
How we reached this conclusion
Garmin's support article excludes supplemental detailed charts on STRIKER. Its model table also distinguishes original STRIKER 4 from Quickdraw-capable models, while Eagle lists Discover and Genesis Live.
DownScan and a larger screen change the viewing workflow
Eagle adds DownScan and a seven-inch screen to the traditional-sonar comparison.
How we reached this conclusion
The panels contain 800 times 480 and 480 times 320 pixels, giving 384,000 and 153,600 respectively. The ratio is 2.5, while the separate DownScan difference comes from the supplied transducer modes.

Meaningful differences
What changes the fit
| What changes | Garmin STRIKER 4 | Lowrance Eagle 7 SplitShot HD | Why it matters |
|---|---|---|---|
| Display | 3.5-inch, 480 x 320 | 7-inch, 800 x 480 | Eagle adds screen space and pixels, without establishing a measured readability result. |
| Display-body width | 91 mm | 225.9 mm | Eagle needs about 135 mm more body width before bracket and cable clearance. |
| Included sonar arrangement | Traditional CHIRP dual-beam transducer | SplitShot HD with CHIRP and DownScan | DownScan is an additional structure-viewing mode in the Eagle package. |
| Detailed chart support | GPS waypoints without supplemental detailed charts | C-MAP Discover support and US Inland selected variant | Marking a waypoint does not provide the chart layers of a chartplotter. |
| On-device contour generation | No Quickdraw generation | Genesis Live supported | Eagle can build local contour maps as the boat covers water. |
| Electrical supply | External DC power | External 12 V DC power | Neither selected head unit should be treated as an internally rechargeable handheld. |
What you give up
Every choice has a cost
If you choose Garmin STRIKER 4
- The small screen gives less display space
If you choose Lowrance Eagle 7 SplitShot HD
- External power and a proper transducer mount remain necessary
Recommendation switch
The decision flips if...
The display body must be narrower than 120 mm
Choose Garmin STRIKER 4. STRIKER 4 is 91 mm wide before installation clearances.
Detailed charts or local contour generation are required
Choose Lowrance Eagle 7 SplitShot HD. Eagle supports the relevant chart and Genesis Live workflows.
There is no suitable external power arrangement
Choose neither. Both selected head units require external electrical power.
What matters in practice
How to make the call
A narrow helm can reject the larger display before purchase
Subtracting 91 mm from 225.9 mm gives a body-width difference of 134.9 mm. A 120 mm-wide mounting space contains the STRIKER body width but cannot contain the Eagle body width. This is only an initial screen: bracket sweep, cable bends and access to controls also need space.
GPS waypoints and detailed charts serve different jobs
Choose based on the navigation information needed before fishing. Returning to a saved spot can work with waypoint tools. Reading compatible detailed chart layers or making local contours is a separate requirement. Confirm the exact lake or coast coverage and selected regional bundle rather than assuming every water is mapped.
DownScan and a larger screen change the viewing workflow
DownScan provides a separate below-boat structure view through the supplied SplitShot HD transducer. The 800 by 480 panel contains 384,000 pixels against 153,600 on STRIKER 4, a 2.5-fold pixel-count difference. Those counts describe display capacity rather than measured fish recognition, sunlight readability or depth performance.
What this comparison cannot tell you
- No matched sonar-depth, target-separation or sunlight-readability test is available
- Chart and contour data should not be treated as a guarantee of safe navigation
