5 Inch vs 4 Inch Fish Finder Comparison
Display size
The Garmin Striker Vivid 4cv features a 4-inch LCD display, which provides a compact viewing area suitable for smaller boats or tight mounting spaces. In contrast, the Garmin Striker 4 is listed with a 5-inch display size in its attributes, offering more screen real estate for reading sonar data. A larger screen generally allows you to see more detail in the water column without straining your eyes. However, the Striker 4 key specs note a 3.5-inch diagonal measurement, creating a slight conflict in the data. Regardless, the 5-inch option presents a bigger visual field for scanning sonar images, while the 4-inch model remains a balanced middle ground for visibility and portability.
Sonar technology
Both units utilize CHIRP sonar technology, which sends a continuous sweep of frequencies to create crisper fish arches and better target separation. The Garmin Striker Vivid 4cv includes CHIRP ClearVü scanning sonar, which provides near-photographic images of the structure and objects below your kayak. It also features traditional CHIRP sonar. The Garmin Striker 4 also offers CHIRP and ClearVü scanning sonar. This means both devices give you a comprehensive view of the underwater environment. You get detailed structure mapping from both, ensuring that neither device lacks the advanced imaging capabilities needed for effective fishing. The sonar performance is essentially equivalent between the two models.
GPS and mapping
The Garmin Striker Vivid 4cv stands out with built-in Quickdraw Contours mapping, allowing you to create and share your own maps of local waters. It also includes high-sensitivity GPS for marking waypoints and viewing boat speed. The Garmin Striker 4 features a waypoint map for marking locations like brush piles and docks, but it does not mention Quickdraw Contours in its specifications. This means the Vivid 4cv offers more advanced mapping capabilities for exploring new areas. If you rely on detailed contour mapping to find new spots, the Vivid 4cv has a clear advantage. The standard Striker 4 is better for simple waypoint navigation.
Physical dimensions
The Garmin Striker Vivid 4cv measures 11.5 inches in width, 6 inches in height, and 8 inches in length, weighing 11.2 ounces. The Garmin Striker 4 is listed with a width of 1.6 inches, height of 5.9 inches, and length of 3.6 inches, weighing 8 ounces. There is a significant discrepancy in the width measurement for the Striker 4, which may refer to the transducer or a different component. Assuming the Vivid 4cv dimensions are correct for the main unit, it is a larger, heavier device. The Striker 4 appears more compact and lighter, making it easier to mount in tight spaces or transport. Size preferences will depend on your available mounting area.
Mounting and control
The Garmin Striker Vivid 4cv comes with a tilt/swivel bailmount bracket, offering flexible positioning for optimal viewing angles. It features an easy-to-use interface with vivid scanning sonar color palettes. The Garmin Striker 4 uses a keyed interface with dedicated buttons, which is described as simple and easy to install. It also includes a built-in flasher format, ideal for ice fishing or vertical jigging. The Vivid 4cv provides a more versatile mounting solution with its tilt/swivel bracket. The Striker 4 offers a classic flasher view that some anglers prefer for specific techniques. Both are designed for straightforward operation without complex menus.
