The catch
Garmin STRIKER Cast GPS
Manual requirements apply to the rod and line.
Side by side
Garmin STRIKER Cast GPS vs STRIKER Vivid 7cv Compared: Each maps contours, Cast works through your phone, and Vivid needs mounted power
Quick verdict
Cast GPS suits repeated shore casts or suitable low-speed kayak use with a compatible phone. Vivid 7cv suits a fixed, powered seven-inch display and the supplied GT20-TM traditional and ClearVu sonar. Quickdraw contours can be created on both, so how the sensor is deployed and what display you need count for more than the shared Garmin mapping name.
Before you buy
Why, and what it costs you
Your casting gear has to meet the manual’s requirement
For casting, Cast GPS needs an appropriate rod, swivel and at least 20 lb test line. Vivid 7cv uses a fixed cabled transducer.
Where this comes from
Garmin names the casting equipment and does not treat just any lightweight fishing setup as suitable.
The catch
Garmin STRIKER Vivid 7cv
You need external power and a plan for mounting, either permanent or removable.

- Why pick it
- Use a castable sensor to survey water from the bank
- Rely on the compatible phone already in your kit
- The catch
- Manual requirements apply to the rod and line.
Garmin STRIKER Vivid 7cv
- Why pick it
- Mount a dedicated seven-inch display
- Go with a fixed GT20-TM sonar installation

What this page compares
Cast GPS and Vivid 7cv weighed on shore deployment, towing limits and the phone or powered display that completes the setup.

In practice
Differences you will notice
Your casting gear has to meet the manual’s requirement
For casting, Cast GPS needs an appropriate rod, swivel and at least 20 lb test line. Vivid 7cv uses a fixed cabled transducer.
How we worked this out
Garmin names the casting equipment and does not treat just any lightweight fishing setup as suitable.
Traveling by power boat favors the fixed transducer
Towing Cast behind a power boat that is underway is not something Garmin recommends. Vivid 7cv is designed around a fixed transducer installation.
How we worked this out
The Cast manual gives a warning about towing above five mph or in choppy conditions.
Contour mapping on both still leaves the display choice
Quickdraw recording works on both, though Cast depends on the app screen and Vivid comes with a powered head unit.
How we worked this out
Contours are generated by both the GPS Cast and Vivid. What each depends on for display and power is different.
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
- Use a castable sensor to survey water from the bank
Facts we checked
- Getting the sensor out: Cast it with a line or tether
- Device needed for viewing: A compatible phone or tablet running the STRIKER Cast app
- Power setup: A rechargeable sensor, plus a phone with its own power
- Use on a power boat while underway: Garmin does not recommend towing
Option B
Garmin, STRIKER Vivid 7cv with GT20-TM
Garmin STRIKER Vivid 7cv
You get a 7-inch display and, in the named Amazon configuration, a transducer.
- Best for
- Mount a dedicated seven-inch display
Facts we checked
- Getting the sensor out: A cabled GT20-TM and its boat mounting hardware
- Device needed for viewing: An integrated 7-inch 800 x 480 screen
- Power setup: External DC power through the supplied power cable
- Use on a power boat while underway: A transducer fixed to the transom or the trolling motor
Spec by spec
Where they really differ
| Spec | Garmin STRIKER Cast GPS | Garmin STRIKER Vivid 7cv | In practice |
|---|---|---|---|
| Sensor deployment | Castable sensor with line or tether | Cabled GT20-TM with boat mounting hardware | Each selected package is suited to a different physical installation. |
| Required viewing device | Compatible phone or tablet with STRIKER Cast app | Integrated 7-inch 800 x 480 screen | Only one side needs a phone. |
| Power system | Rechargeable sensor plus separately powered phone | External DC power through supplied power cable | Every device in use belongs in the complete power plan. |
| Power-boat use while underway | Towing not recommended by Garmin | Fixed transom or trolling-motor transducer installation | Do not treat a castable sensor as a transducer to tow behind a power boat. |
| Quickdraw contour generation | Supported on this GPS variant | Supported | Local contours can be recorded by either, given suitable position and sonar data. |
Trade-offs
What each pick costs you
With Garmin STRIKER Cast GPS
- The phone's power and the wireless connection are still dependencies.
With Garmin STRIKER Vivid 7cv
- The transducer is cabled and cannot be cast.
Change of plan
When the answer changes
I plan to put the sonar out from shore using suitable casting gear
Go with Garmin STRIKER Cast GPS. That arrangement works with Cast GPS.
I want a fixed screen plus a transducer mounted on the boat
Go with Garmin STRIKER Vivid 7cv. That installation suits the Vivid GT20-TM package.
I intend to tow a loose sensor fast
Neither model fits. That plan is not supported by either documented setup.
Decision guide
How to decide
For repeated shore casts or suitable low-speed kayak use with a compatible phone, pick Cast GPS. For a fixed, powered seven-inch display with the supplied GT20-TM traditional and ClearVu sonar, pick Vivid 7cv. Both create Quickdraw contours, so the shared Garmin mapping name should not decide it. Sensor deployment and display requirements matter more.
Your casting gear has to meet the manual’s requirement
Check the rod and line you will use to deploy Cast GPS before choosing it for bank fishing. A light six-pound-line outfit falls short of the specified twenty-pound minimum. Include suitable gear, or use the documented tether arrangement where appropriate. Vivid 7cv spares you the casting but requires its own mount, power and transducer installation.
Traveling by power boat favors the fixed transducer
When the sonar has to stay in use as the power boat runs between spots, pick the mounted Vivid installation and follow the transducer mounting instructions. Cast can still handle shore work or suitable low-speed canoe and kayak use. The wireless range claim is not permission to tow it faster. Neither plan here guarantees clean sonar returns at every boat speed.
Contour mapping on both still leaves the display choice
Either workflow can deliver local depth mapping if that is your main goal, so decide by how you will carry, view and power the equipment. Vivid keeps the phone free and puts the map on its own screen. Cast can cut down on permanent boat hardware, yet its sensor battery figure leaves out the phone or tablet running the app.
What this page can’t tell you
- No matched test of fish detection, sonar range, battery or connection was performed. How much Quickdraw covers and how good it is depend on the survey you carry out.
