5 vs 7 Inch Display Comparison
Display Size
The Garmin Striker 4 features a 3.5-inch diagonal display, while the Striker Vivid 7sv offers a 7-inch screen. The larger 7-inch unit provides significantly more screen real estate for viewing sonar data and maps. This extra space makes it easier to distinguish between fish arches and underwater structure, especially in choppy water. The smaller 3.5-inch screen is compact and sufficient for basic sonar reading, but it offers less detail. For anglers who prioritize clear visibility of sonar images without squinting, the larger display is the practical choice.
Connectivity
The Striker Vivid 7sv includes Wi-Fi connectivity, allowing you to pair the device with the ActiveCaptain app on a compatible smartphone. This feature lets you transfer waypoints, receive software update notifications, and access the Garmin Quickdraw Community. The Striker 4 lacks any wireless connectivity options, relying solely on its local interface. If you want to manage your sonar data from your phone or share maps with other users, the Vivid 7sv is the only option. The Striker 4 is a standalone unit with no digital integration.
Mapping Features
The Striker Vivid 7sv comes with built-in Quickdraw Contours mapping, enabling you to create detailed maps of unfamiliar waters. This feature is useful for exploring new lakes and marking depth changes. The Striker 4 offers a basic waypoint map for marking locations like brush piles or docks, but it does not include advanced contour mapping capabilities. If you need to chart underwater topography for future trips, the Vivid 7sv provides superior mapping tools. The Striker 4 is better suited for simple navigation and location marking.
Portability
The Striker 4 is lightweight, weighing only 8 ounces, and has a compact form factor. The Striker Vivid 7sv weighs 5.4 pounds and is considerably larger, with dimensions of 11.4 inches in length. The smaller unit is easier to mount on smaller kayaks or portable boats where space and weight are critical constraints. The larger unit requires more mounting space and adds significant weight to your setup. For anglers prioritizing a lightweight, compact setup, the Striker 4 is the more portable choice.
Sonar Technology
Both units support CHIRP sonar for clearer fish arches and better target separation. The Striker 4 includes ClearVü scanning sonar for near-photographic images of structure. The Striker Vivid 7sv adds Vivid Scanning Sonar with color palettes to easily distinguish fish and structure. It also supports Chirp SideVü scanning sonar with a compatible transducer, providing a wider view of the water column. If you want advanced scanning capabilities and color sonar images, the Vivid 7sv offers more technical features. The Striker 4 provides essential sonar without the advanced scanning options.

Frequently asked questions
Can a 5 inch fish finder replace a 7 inch model?
It depends on your boat size and fishing style. The 5-inch Garmin Striker 4 weighs only 8 ounces and measures 3.6 inches in length. This compact form factor suits small boats or ice fishing. However, you sacrifice the detailed mapping and large viewing area provided by the 7-inch Striker Vivid 7sv.
Does the 7 inch screen show GPS maps better?
Yes, the larger display offers more room for chartplotting data. The 7-inch Garmin Striker Vivid 7sv includes built-in GPS and mapping features. The 5-inch Striker 4 also has GPS, but its smaller screen limits how much map detail you can view comfortably while navigating.
Is CHIRP sonar available on both sizes?
The 5-inch Garmin Striker 4 includes CHIRP sonar technology. This provides clearer images of fish and structure. The 7-inch Striker Vivid 7sv also features advanced sonar capabilities. Both units deliver essential sonar performance, though the larger screen allows for easier interpretation of the returned data.
