Who it fits

Key specs explained

Display Size: 3.5"

The 3.5-inch screen offers a compact view that fits easily on small kayak decks. You get a clear look at sonar returns without taking up much space. This size is practical for anglers who prioritize a clutter-free cockpit. Larger screens provide more detail, but this unit keeps the focus on essential data while maintaining a low profile.

Control: Keyed interface with dedicated buttons

Dedicated buttons allow you to operate the device without navigating complex menus. This is useful when your hands are wet or cold. You can quickly change settings or mark waypoints with a single press. This interface is simpler than touchscreen models, reducing the chance of accidental inputs while you are paddling or casting.

Sonar Type: CHIRP

CHIRP sonar sends a continuous sweep of frequencies for better target separation. You will see crisper fish arches and clearer bottom structure compared to traditional sonar. This technology helps you distinguish between fish and debris. It is ideal for kayak anglers who need precise depth readings and clear images of underwater objects.

Max Depth: 1,600 ft freshwater

The unit reaches depths up to 1,600 feet in freshwater environments. This range covers most inland lakes and rivers where kayak fishing occurs. You can monitor deep structures or drop-offs without losing signal. For saltwater use, the limit is 750 feet. This depth capability ensures reliable performance across various common fishing scenarios.

Mount Type: Portable kit

The portable kit allows you to move the fish finder between different boats or locations. You are not locked into a permanent installation. This flexibility is valuable for kayak anglers who may also use other vessels. The mount keeps the unit secure while allowing easy removal for travel or storage.

The unit handles freshwater and saltwater environments, with a maximum depth rating of 1,600 feet in fresh water and 750 feet in salt water.

Before you buy this unit

You need to verify your vessel compatibility before purchasing. This model includes a kayak in-hull transducer mount, which is ideal for fishing kayaks. However, you must ensure your kayak has a hull thickness that allows for proper transducer installation. The portable kit is designed for easy setup, but you should check if your current mounting hardware matches the included components. Since this unit lacks a built-in GPS receiver beyond waypoint mapping, you may want to pair it with a separate GPS device for precise navigation. Regular maintenance is simple. Rinse the 3.5-inch display and keypad with fresh water after saltwater use to prevent corrosion. Keep the connections dry. This fish finder sits alongside other options in our 1 kayak guide as a budget-friendly, no-frills choice. It suits anglers who value simplicity over complex mapping features. If you need advanced chartplotters, this may not meet your needs. Check your specific kayak model requirements to ensure a secure fit.

Check before you buy

• Verify your kayak hull thickness for the in-hull transducer mount.
• Check if your current mounting hardware fits the portable kit.
• Confirm you do not need advanced built-in GPS chartplotters.
• Ensure you have fresh water for regular cleaning after use.
