Garmin STRIKER Cast GPS
A phone is required, and its battery is a separate matter
Side by side
Garmin STRIKER Cast GPS vs Lowrance Eagle 7 SplitShot HD Compared: Garmin can be cast from shore, while Eagle needs a powered installation on a boat
Quick verdict
STRIKER Cast GPS is the pick when the sensor has to be cast from shore and your phone can act as the display. Eagle 7 SplitShot HD is the pick when the boat can carry a mounted transducer, a seven-inch screen and an external power supply. The two call for different fishing setups before sonar detail even becomes the deciding factor.
Before you buy
Why, and what it costs you
Casting from shore drops the boat-installation assumption
With STRIKER Cast GPS, the sonar sensor can sit away from the bank with no fixed transducer mount.
Where this comes from
According to the Cast manual, a floating sensor can be cast with appropriate tackle. Eagle's package uses a wired, mounted SplitShot HD transducer and a dedicated head unit.

In practice
Differences you will notice
Casting from shore drops the boat-installation assumption
With STRIKER Cast GPS, the sonar sensor can sit away from the bank with no fixed transducer mount.
How we worked this out
According to the Cast manual, a floating sensor can be cast with appropriate tackle. Eagle's package uses a wired, mounted SplitShot HD transducer and a dedicated head unit.
Even a rechargeable sensor leaves you managing a second battery
Both the sensor and the phone need charge for STRIKER Cast. Eagle needs a separate external DC supply.
How we worked this out
Cast has an internal sensor battery but still requires a powered compatible phone. The display supplied with Eagle must receive external DC power, so neither setup rests on only one universal battery assumption.
Eagle's electrical figure helps with planning only so far
At full backlight, the published 0.55 A at 12 V corresponds to 6.6 W.
How we worked this out
Multiplying Eagle's stated full-backlight input of 0.55 A at 12 V gives 6.6 W. Cast's 200 ft figure describes its wireless connection range, so it cannot stand in for sonar depth.
Option A
Garmin, STRIKER Cast GPS
Garmin STRIKER Cast GPS
A transducer comes in the named Amazon configuration. Its listed sonar depth class reaches 150 feet under the maker conditions.
- Best for
- Cast the sensor from shore to scan the water
Facts we checked
- Getting the sensor out: A floating sensor that you cast or tether suitably
- Screen: A compatible phone and the STRIKER Cast app
- Power for sensor and display: A rechargeable sensor, plus a phone with its own power
- Making contours locally: Quickdraw contours on the GPS variant
Option B
Lowrance, Eagle 7 SplitShot HD
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.
- Best for
- Put the sonar on a dedicated seven-inch display
Facts we checked
- Getting the sensor out: A wired SplitShot HD transducer, mounted
- Screen: A dedicated 7-inch 800 x 480 display
- Power for sensor and display: An external 12 V DC supply for the head unit
- Making contours locally: Genesis Live contour mapping
Spec by spec
Where they really differ
| Spec | Garmin STRIKER Cast GPS | Lowrance Eagle 7 SplitShot HD | In practice |
|---|---|---|---|
| Sensor deployment | Castable or suitably tethered floating sensor | Mounted wired SplitShot HD transducer | Different physical hardware is required for shore casting than for a fixed boat installation. |
| Display | Compatible phone and STRIKER Cast app | Dedicated 7-inch 800 x 480 display | The Garmin operating system includes a phone, whereas Eagle supplies its own screen. |
| Sensor and display power | Rechargeable sensor plus separately powered phone | External 12 V DC supply for the head unit | A boat with no battery cannot provide the supply Eagle requires. |
| Local contour generation | Quickdraw contours on the GPS variant | Genesis Live contour mapping | Contours can be built with either, but deployment and chart systems are different. |
| Published connection or electrical limit | Wireless range up to 60 m or 200 ft, condition dependent | 550 mA at 12 V with full backlight | Planning for Cast means leaving connection margin, and planning for Eagle means budgeting external energy. |
| Detailed chart route | Quickdraw-focused STRIKER Cast app | C-MAP Discover support and one microSD slot | Before you choose the boat-navigation workflow, verify the actual waters and chart coverage. |
Trade-offs
What each pick costs you
With Garmin STRIKER Cast GPS
- Conditions and the phone determine wireless range
With Lowrance Eagle 7 SplitShot HD
- A castable shore sensor is not part of the fixed installation
Change of plan
When the answer changes
The main job is casting the sonar from shore
Go with Garmin STRIKER Cast GPS. That physical workflow is supported by the floating Cast GPS sensor.
Requirements are a dedicated screen and a mounted DownScan transducer
Go with Lowrance Eagle 7 SplitShot HD. Eagle comes with those hardware elements.
There is neither a compatible phone nor external boat power
Neither model fits. A required part of its operating setup is missing from each option.
Decision guide
How to decide
If the sensor must be cast from shore and the phone can serve as the display, go with STRIKER Cast GPS. If your boat can carry a mounted transducer, a seven-inch screen and an external power supply, go with Eagle 7 SplitShot HD. Fishing setup comes first, and sonar detail only decides after that.
Casting from shore drops the boat-installation assumption
Appropriate casting tackle and line strength are specified by the manufacturer. Plan safe casting space and keep the compatible phone available. Eagle's supplied wired transducer and dedicated head unit are meant for a mounted setup, so buying only the display does not give you the same bank-fishing workflow.
Even a rechargeable sensor leaves you managing a second battery
On a walking session, a phone and a charged castable sensor can spare you a dedicated fish-finder battery. On a boat day, the dedicated Eagle screen keeps the phone free but brings a mounted display and an electrical connection. Without the actual battery and usage conditions, neither arrangement comes with an all-day runtime guarantee.
Eagle's electrical figure helps with planning only so far
For the stated Eagle condition, multiplying current by voltage gives 6.6 W. That can feed into 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. It is not a sonar-depth rating or a dependable casting distance in every setting.
What this page can’t tell you
- Do not read connection range as a sonar-depth specification
- There is no matched test of fish-target identification, sunlight or battery runtime
