The ReelSonar iBobber introduces a modern approach to fish finding by leveraging smartphone technology. This sphere-shaped device connects via Bluetooth to transform your phone into a sophisticated fishing tool, eliminating the need for a separate display unit on your kayak.
One of the iBobber’s standout features is its GPS mapping functionality, allowing anglers to create detailed maps of productive fishing spots. This proves particularly valuable for kayak fishing, where returning to exact locations can be challenging without visual landmarks. The ability to mark hotspots and underwater structures significantly enhances fishing efficiency over time.
The sonar technology can scan depths up to 135 feet, providing information on fish location, approximate size, and bottom contour. While this range is suitable for most kayak fishing scenarios, it falls short of what dedicated premium units offer for deeper water exploration.
Despite its innovative approach, the iBobber does present some practical challenges. The Bluetooth connection occasionally experiences interference in crowded fishing areas, and the reliance on a smartphone means exposing your valuable device to potential water damage. The battery life of both the iBobber and your smartphone need consideration for full-day fishing trips.

A fish finder for kayak is a specialized electronic device designed to detect and display underwater objects, structures, and fish using sonar technology. These compact units represent a subset of marine electronics specifically optimized for the unique constraints and requirements of kayak fishing.
Unlike traditional boat-mounted fish finders, kayak models prioritize portability and efficiency while maintaining essential functionality. They typically feature waterproof construction, compact displays, and versatile mounting options that accommodate the limited space and exposure to elements inherent to kayak fishing. Most kayak fish finders can be categorized into three main types: fixed units with dedicated displays, portable castable devices that connect to smartphones, and transducer-only systems that pair with existing marine electronics.
The core technology behind these devices involves emitting sound waves that bounce off underwater objects and return to the transducer, with the time differential and signal strength translated into visual information about depth, structure, and fish presence. Modern kayak fish finders have transformed fishing from a game of chance to a data-driven pursuit, enabling anglers to make informed decisions about location, technique, and timing based on real-time underwater
Ensure the fish finder includes appropriate mounting hardware specifically designed for kayak installation, as standard boat mounts often don’t work well on kayak surfaces.
Consider battery type, life, and recharging capabilities, as kayaks lack the electrical systems of larger boats; look for units with at least 8-10 hours of continuous operation.
Prioritize screens with high brightness, anti-glare technology, and good resolution, as kayaking exposes the display to direct sunlight and water reflections.
Find the optimal balance between screen size and overall unit weight, as every ounce matters when paddling long distances.
Verify the IPX rating (minimum IPX7 recommended) to ensure protection against water immersion, which is almost inevitable in kayak fishing scenarios.
Evaluate whether the transducer design works with your specific kayak model, considering options like through-hull, scupper-hole, or side-mount installations.
Determine whether traditional sonar, CHIRP, side imaging, or down imaging best suits your fishing environment and target species.
Avoid fish finders designed primarily for larger boats that will consume excessive space and power on a kayak.
Steer clear of systems with steep learning curves that require extensive attention while you’re trying to paddle and fish.
Don’t purchase units with mounting hardware that requires drilling or permanent modification to your kayak unless you’re comfortable with such alterations.
Reject any fish finder rated less than IPX7, as lower ratings won’t withstand the water exposure inherent to kayak fishing.
Don’t select units with screens that become unreadable in direct sunlight, as this is the primary viewing condition during kayak fishing.
