Key Specs to Check Before Buying
-
Match display size to your needs
Screen size dictates how much detail you see and how much deck space you use. A 3.5-inch unit like the Garmin Striker 4 offers basic depth tracking in a tiny footprint. If you need more data, a 7-inch model such as the Garmin Striker Plus 7sv provides a larger view for side-scanning. The Humminbird XPLORE 12 features a massive 12-inch touchscreen for those with ample dash room. Choose a size that fits your kayak’s console without blocking your view or paddling motion.
-
Check sonar type for clarity
Sonar type determines how clearly you see fish and structure. CHIRP sonar, found in the Garmin Striker 4, provides reliable depth tracking and better target separation. ClearVü scanning sonar, available in the Garmin Striker Vivid 4cv, gives you a detailed image of the bottom directly below your kayak. Down Imaging, like that on the Humminbird Helix 5 G3 Down Imaging, shows a vertical slice of the water column. Select the sonar type that matches the water conditions you frequent most often.
-
Verify GPS and mapping features
Built-in GPS allows you to mark waypoints and track your route. The Garmin Striker 4 includes GPS for basic navigation. The Humminbird Helix 5 G3 Portable adds full mapping capabilities in a travel-friendly case, ideal for moving between lakes. The Humminbird Helix 7 G4 MEGA Side Imaging includes coastal basemaps for broader area coverage. If you rely on navigation, ensure the unit has the GPS and map data you need without requiring external devices.
-
Consider weight for portability
Weight matters if you carry your kayak frequently. The Garmin Striker 4 weighs only 8 ounces, making it nearly weightless on your deck. Heavier units like the Humminbird XPLORE 12 weigh 6.31 pounds and require secure mounting. The Garmin Striker 5cv is lightweight at 1 pound. If you need a grab-and-go setup, the Humminbird Helix 5 G3 Portable is designed for travel. Check the weight to ensure it does not unbalance your kayak or complicate transport.
-
Look for included transducer type
All units here include a transducer, but the type varies. The Humminbird PiranhaMAX 4 uses a transom-mounted transducer, which is simple to install but may interfere with paddling. The Garmin Striker 5cv includes a transducer for ClearVü scanning, offering detailed bottom imaging. The Humminbird Helix 7 G4N pairs with MEGA Down Imaging for precise structure views. Ensure the included transducer matches your mounting style and the sonar technology you want to use for your specific fishing conditions.

Do these fish finders include GPS mapping?
Many models include built-in GPS for navigation and waypoint storage. The Garmin Striker 4, Striker Vivid 4cv, and Humminbird Helix 5 G3 all feature GPS.

The Garmin Striker 5cv pairs both technologies. The Humminbird Helix 5 G3 includes Dual Spectrum CHIRP for enhanced clarity. These modes help you distinguish fish from structure.
Can I use a fish finder with side imaging on a kayak?
