9 Inch or 4 Inch Specs Compared
Display Size
The Lowrance Eagle 9 TripleShot HD features a large 9-inch IPS screen. This size gives SideScan, sonar, structure, and chart details more room to display clearly. You get a broader view of your surroundings and fish targets. In contrast, the Garmin Striker Vivid 4cv has a 4-inch LCD display. This smaller screen is compact and easier to manage in tight spaces. It uses vivid scanning sonar color palettes to distinguish fish and structure. The 9-inch model offers significantly more visual real estate for detailed navigation and sonar reading compared to the 4-inch unit.
Sonar Technology
Sonar capabilities differ between these two fish finders. The Lowrance Eagle 9 uses TripleShot HD, which combines SideScan, DownScan Imaging, and CHIRP sonar through one included transducer. It also features FishReveal to overlay CHIRP fish targets on DownScan detail. The Garmin Striker Vivid 4cv includes a GT20 transducer for built-in Garmin CHIRP traditional sonar and CHIRP ClearVü scanning sonar. While the Lowrance offers side scanning for a wider search area, the Garmin provides traditional and clear viewing sonar. Each approach targets different fishing styles and preferences.
Mapping Features
Mapping options vary in how they are provided. The Lowrance Eagle 9 comes with a C-MAP DISCOVER microSD card. This card provides inland and coastal chart coverage across the U.S. and Canada. You must use this external card for charting. The Garmin Striker Vivid 4cv includes built-in Quickdraw Contours mapping. This feature allows you to create and share custom maps directly on the device without needing an external card. The Garmin offers more immediate and flexible mapping capabilities through its internal system, whereas the Lowrance relies on pre-loaded external data.
Weight and Portability
Portability is a key factor for many kayakers. The Garmin Striker Vivid 4cv weighs only 11.2 ounces. This light weight makes it very easy to mount and move around your kayak. The Lowrance Eagle 9 TripleShot HD weighs 2 pounds. This is significantly heavier than the Garmin unit. The extra weight of the Lowrance may require a sturdier mount. If you prioritize a lightweight setup that does not add much bulk to your vessel, the Garmin is the lighter option. The Lowrance is nearly twice as heavy.
GPS and Marking
GPS functionality helps you navigate and mark spots. The Garmin Striker Vivid 4cv has a high-sensitivity GPS. This allows you to mark waypoints, create routes, and view your boat’s speed accurately. The Lowrance Eagle 9 TripleShot HD data does not explicitly list built-in GPS capabilities in its key specs. It focuses on sonar and charting via the microSD card. If you need reliable GPS marking and speed tracking without additional modules, the Garmin provides this directly. The Lowrance may require separate GPS integration for similar features.

Anglers wanting maximum detail and chart coverage

A tilt/swivel bailmount bracket is included for easy installation on your boat.
