Head-to-head
Garmin STRIKER Cast GPS vs Lowrance Eagle 7 SplitShot HD: Garmin casts from shore, Eagle needs a powered boat installation
The short answer
Choose STRIKER Cast GPS when the sensor must be cast from shore and the phone can serve as the display. Choose Eagle 7 SplitShot HD when the boat can carry a mounted transducer, a seven-inch screen and an external power supply. These products ask for different fishing setups before sonar detail becomes the deciding factor.
Before you choose
The reasoning and the trade-offs
Shore casting removes the boat-installation assumption
STRIKER Cast GPS can put the sonar sensor away from the bank without a fixed transducer mount.
What this is based on
The Cast manual permits a floating sensor to be cast using appropriate tackle. Eagle's package uses a wired, mounted SplitShot HD transducer and a dedicated head unit.

Winner by situation
Start with what you need it to do
The sensor must be cast from a bank with no boat available
STRIKER Cast is built around that deployment method.
- Garmin STRIKER Cast GPS
- Better fit
- Lowrance Eagle 7 SplitShot HD
- Not suitable
The phone must stay available for calls and navigation throughout fishing
Eagle provides a separate display, while Cast depends on the phone screen.

What matters in practice
The differences that matter
Shore casting removes the boat-installation assumption
STRIKER Cast GPS can put the sonar sensor away from the bank without a fixed transducer mount.
How we reached this conclusion
The Cast manual permits a floating sensor to be cast using appropriate tackle. Eagle's package uses a wired, mounted SplitShot HD transducer and a dedicated head unit.
A rechargeable sensor still leaves a second battery to manage
STRIKER Cast needs both sensor charge and phone charge. Eagle needs a separate external DC supply.
How we reached this conclusion
Cast has an internal sensor battery but still requires a powered compatible phone. Eagle supplies a display that must receive external DC power, so neither setup has only one universal battery assumption.
Eagle's electrical figure gives a limited planning input
The published 0.55 A at 12 V corresponds to 6.6 W at full backlight.
How we reached this conclusion
Eagle's stated full-backlight input is 0.55 A at 12 V, giving 6.6 W by multiplication. Cast's 200 ft figure describes its wireless connection range and cannot be substituted for sonar depth.
Choice A
Garmin, STRIKER Cast GPS
Garmin STRIKER Cast GPS
The listed sonar depth class reaches 150 feet under the maker conditions. The named Amazon configuration includes a transducer.
- Best matched use
- Cast the sensor to scan water from shore
Checked facts
- Sensor deployment: Castable or suitably tethered floating sensor
- Display: Compatible phone and STRIKER Cast app
- Sensor and display power: Rechargeable sensor plus separately powered phone
- Local contour generation: Quickdraw contours on the GPS variant
Choice B
Lowrance, Eagle 7 SplitShot HD
Eagle 7 SplitShot HD
A seven-inch IPS fishfinder with SplitShot HD, GPS chart support and Genesis Live mapping. It gives more viewing area than Eagle 5 while keeping the same 800 × 480 pixel matrix.
- Best matched use
- Keep sonar on a dedicated seven-inch display
Checked facts
- Sensor deployment: Mounted wired SplitShot HD transducer
- Display: Dedicated 7-inch 800 x 480 display
- Sensor and display power: External 12 V DC supply for the head unit
- Local contour generation: Genesis Live contour mapping
Meaningful differences
What changes the fit
| What changes | Garmin STRIKER Cast GPS | Lowrance Eagle 7 SplitShot HD | Why it matters |
|---|---|---|---|
| Sensor deployment | Castable or suitably tethered floating sensor | Mounted wired SplitShot HD transducer | Shore casting and a fixed boat installation require different physical hardware. |
| Display | Compatible phone and STRIKER Cast app | Dedicated 7-inch 800 x 480 display | A phone is part of the Garmin operating system, while Eagle supplies its screen. |
| Sensor and display power | Rechargeable sensor plus separately powered phone | External 12 V DC supply for the head unit | A battery-free boat does not provide Eagle's required supply. |
| Local contour generation | Quickdraw contours on the GPS variant | Genesis Live contour mapping | Both can build contours, but their deployment and chart systems differ. |
| Published connection or electrical limit | Wireless range up to 60 m or 200 ft, condition dependent | 550 mA at 12 V with full backlight | Cast planning needs connection margin, while Eagle planning needs an external energy budget. |
| Detailed chart route | Quickdraw-focused STRIKER Cast app | C-MAP Discover support and one microSD slot | Verify the actual waters and chart coverage before selecting the boat-navigation workflow. |
What you give up
Every choice has a cost
If you choose Garmin STRIKER Cast GPS
- Wireless range depends on conditions and the phone
If you choose Lowrance Eagle 7 SplitShot HD
- The fixed installation does not provide a castable shore sensor
Recommendation switch
The decision flips if...
Casting the sonar from shore is the main job
Choose Garmin STRIKER Cast GPS. The floating Cast GPS sensor supports that physical workflow.
A dedicated screen and mounted DownScan transducer are required
Choose Lowrance Eagle 7 SplitShot HD. Eagle supplies those hardware elements.
No compatible phone and no external boat power are available
Choose neither. Each option lacks a required part of its operating setup.
What matters in practice
How to make the call
Shore casting removes the boat-installation assumption
The manufacturer specifies appropriate casting tackle and line strength. Plan safe casting space and keep the compatible phone available. Eagle's supplied wired transducer and dedicated head unit are intended for a mounted setup, so buying only the display does not create the same bank-fishing workflow.
A rechargeable sensor still leaves a second battery to manage
For a walking session, carrying a phone and charged castable sensor can avoid a dedicated fish-finder battery. For a boat day, the dedicated Eagle screen keeps the phone free but adds a mounted display and electrical connection. Neither arrangement makes an all-day runtime guarantee without the actual battery and usage conditions.
Eagle's electrical figure gives a limited planning input
Multiplying current by voltage gives 6.6 W for the stated Eagle condition. It can inform a boat battery budget, but the battery's usable energy, other loads and reserve determine runtime. The Garmin 200 ft figure is a maximum wireless connection range, not a sonar-depth rating or a dependable casting distance in every setting.
What this comparison cannot tell you
- Connection range is not a sonar-depth specification
- No matched fish-target identification, sunlight or battery-runtime test is available
