The Lowrance Elite FS 9 Fish Finder is designed for anglers who want detailed underwater insights. It features a 9-inch high-resolution multi-touch LCD screen, making it easy to view and navigate through various settings. One of its standout features is the Active Imaging 3-in-1 transducer, which combines CHIRP, SideScan, and DownScan sonar technologies. This allows for clear and refined imaging of underwater structures and fish. Additionally, it supports ActiveTarget Live Sonar, which provides real-time images of fish and their movements, enhancing the fishing experience.

The preloaded C-MAP Contour+ charts are another significant advantage, providing detailed mapping of 8,900 U.S. lakes to help locate prime fishing spots. The inclusion of full networking capabilities like integrated wireless, NMEA 2000, and Ethernet connectivity allows for easy integration with other devices and data sharing. However, the device is relatively heavy at 4.53 kilograms, which might affect portability for some users, especially those looking for a lightweight option to carry on a kayak.

The high-tech features and networking options might be overwhelming for beginners who prefer simpler fish finders. Additionally, it requires a 12 Volt DC power source, which is something to consider for long fishing trips. The Lowrance Elite FS 9 is a robust and feature-rich fish finder suitable for serious anglers who need advanced sonar capabilities and detailed mapping, but its weight and complexity might be a drawback for casual users or those prioritizing portability.

The Humminbird 411660-1 Helix 5 Chirp GPS G3 is an excellent choice for both novice and experienced anglers looking for a reliable kayaker fish finder. One of its standout features is the 5-inch LCD display, providing a clear view of underwater structures and fish, thanks to the Dual Spectrum CHIRP sonar technology. This sonar system offers both Wide and Narrow modes, ensuring you can cover large areas or zoom in on specific details effectively. The internal GPS and enhanced basemap allow users to navigate confidently while identifying important points of interest, such as marinas and hazards, which is a definite plus for safety during outings.

In terms of portability, this fish finder is reasonably lightweight and compact, making it suitable for kayak use. Users will appreciate the ease of installation with the included transom-mount transducer and mounting hardware. The AutoChart Live feature is a significant advantage, letting you create real-time maps of your fishing spots, providing an edge in understanding the underwater environment.

There are a few drawbacks to consider. The 5-inch display, while adequate, may feel a bit small for some users, especially when trying to view more detailed information simultaneously. Additionally, being corded limits its power source options compared to battery-operated models, which could be a concern during long trips away from power sources. The product’s price point may also be higher than basic models, making it less accessible for beginners just starting.

The Garmin Striker Vivid 7cv is a solid choice for kayak anglers looking for an easy-to-use fishfinder with a good-sized 7-inch color display. Its vivid scanning sonar color palettes make it easier to spot fish and underwater structures, which is great when you're on the water and need clear visuals. The included GT20 transducer supports both traditional CHIRP sonar and CHIRP ClearVü scanning sonar, offering detailed views of what's beneath your kayak.

You get a reliable high-sensitivity GPS that helps mark fishing spots, create routes, and check your speed — a handy feature for navigation and trip planning. The fishfinder also comes with built-in Quickdraw Contours mapping, letting you customize your own depth maps. It connects via Wi-Fi to the ActiveCaptain app, so you can easily transfer waypoints or get software updates right on your compatible smartphone, which adds convenience.

The display is bright and clear, though the resolution isn’t the highest on the market, but sufficient for most kayak fishing needs. The device is surface-mounted and weighs about 4.4 pounds, which is somewhat heavy for ultra-light kayak setups but still manageable. It runs on battery power, so planning for charging or spare batteries on longer trips is recommended. The button-based interface is straightforward but might feel a little basic if you're used to touchscreen devices. This Garmin model suits kayak fishermen who want a dependable, user-friendly fishfinder with strong sonar features and GPS, while it may not be the lightest or have the most advanced screen available.
