The catch
Garmin STRIKER 4
Without supplemental detailed charts or Quickdraw generation
Side by side
STRIKER 4 is the choice when a narrow display and basic sonar with GPS waypoints cover the trip. Eagle 7 SplitShot HD is the choice when the boat needs a larger screen, DownScan and supported detailed charts. Either way, measure the mounting space and build the electrical supply and transducer installation into the plan.
Before you buy
Going by published widths, the Eagle body is 134.9 mm wider than STRIKER 4.
Where this comes from
Published head-unit widths are 225.9 mm for Eagle and 91 mm for STRIKER 4, a difference of 134.9 mm. The example opening is 120 mm before bracket or cable allowances.
The catch
Without supplemental detailed charts or Quickdraw generation
The catch
The head unit is a lot wider

STRIKER 4 and Eagle 7 SplitShot HD set against each other for boats where a small helm, detailed lake charts or DownScan shape the installation.
STRIKER 4 is the choice when a narrow display and basic sonar with GPS waypoints cover the trip. Eagle 7 SplitShot HD is the choice when the boat needs a larger screen, DownScan and supported detailed charts. Either way, measure the mounting space and build the electrical supply and transducer installation into the plan.
Which one fits
Eagle's 225.9 mm width does not fit the initial screen, but the published 91 mm STRIKER body width does.
Eagle supports C-MAP Discover, but STRIKER cannot accept supplemental detailed charts.
DownScan comes in the SplitShot HD package.
Each covers the broad job, which makes available mounting space and desired chart detail the distinctions worth using.
In practice
Going by published widths, the Eagle body is 134.9 mm wider than STRIKER 4.
Published head-unit widths are 225.9 mm for Eagle and 91 mm for STRIKER 4, a difference of 134.9 mm. The example opening is 120 mm before bracket or cable allowances.
Eagle can use supported detailed C-MAP charts, while STRIKER 4 can mark locations.
On STRIKER, supplemental detailed charts are ruled out by Garmin's support article. Its model table also separates original STRIKER 4 from Quickdraw-capable models, and Eagle lists Discover and Genesis Live.
DownScan and a seven-inch screen are what Eagle adds to the traditional-sonar comparison.
The panels hold 800 times 480 and 480 times 320 pixels, which gives 384,000 and 153,600 respectively. The ratio is 2.5. The separate DownScan difference comes from the supplied transducer modes.

Garmin, STRIKER 4 with Dual-Beam Transducer
A 3.5-inch display is built in, and the Amazon configuration named here ships with a transducer.

Lowrance, Eagle 7 SplitShot HD
This seven-inch IPS fishfinder pairs SplitShot HD with GPS chart support and Genesis Live mapping. Compared with Eagle 5 it offers more viewing area on the same 800 × 480 pixel matrix.
Spec by spec
| Spec | Garmin STRIKER 4 | Lowrance Eagle 7 SplitShot HD | In practice |
|---|---|---|---|
| Display | 3.5-inch, 480 x 320 | 7-inch, 800 x 480 | Eagle brings more screen space and pixels, though no measured readability result is established. |
| Display-body width | 91 mm | 225.9 mm | Before bracket and cable clearance, Eagle takes up about 135 mm more body width. |
| Included sonar arrangement | Traditional CHIRP dual-beam transducer | SplitShot HD with CHIRP and DownScan | The Eagle package has an additional structure-viewing mode, DownScan. |
| Detailed chart support | GPS waypoints without supplemental detailed charts | C-MAP Discover support and US Inland selected variant | A chartplotter's chart layers do not come from marking a waypoint. |
| On-device contour generation | No Quickdraw generation | Genesis Live supported | As the boat covers water, Eagle can build local contour maps. |
| Electrical supply | External DC power | External 12 V DC power | Do not treat either selected head unit as an internally rechargeable handheld. |
Trade-offs
Change of plan
Go with Garmin STRIKER 4. Before installation clearances, STRIKER 4 is 91 mm wide.
Go with Lowrance Eagle 7 SplitShot HD. The relevant chart and Genesis Live workflows are supported by Eagle.
Neither model fits. External electrical power is required by both selected head units.
Decision guide
A narrow display with basic sonar and GPS waypoints that cover the trip points to STRIKER 4. A boat that needs a larger screen, DownScan and supported detailed charts points to Eagle 7 SplitShot HD. Measure the mounting space first, and count the electrical supply and transducer installation in either plan.
A body-width difference of 134.9 mm comes from subtracting 91 mm from 225.9 mm. A 120 mm-wide mounting space holds the STRIKER body but not the Eagle body. Treat this as a first screen only, since bracket sweep, cable bends and access to controls also need space.
Decide by the navigation information you need before you start fishing. Waypoint tools can handle returning to a saved spot. Reading compatible detailed chart layers or making local contours is a separate requirement. Confirm the exact lake or coast coverage and the selected regional bundle instead of assuming every water is mapped.
The supplied SplitShot HD transducer gives DownScan, a separate view of structure below the boat. The 800 by 480 panel holds 384,000 pixels against 153,600 on STRIKER 4, which is a 2.5-fold difference in pixel count. Those counts describe display capacity, not measured fish recognition, sunlight readability or depth performance.
