What To Consider When Picking The Best Kayak Fish Finder

There is a glut of kayak fish finders in the market. New and improved models keep popping up now and then. If you are new to the game of fishing, you would be at a loss to pick the one that suits you. If that is the case, then read on as we highlight certain factors that you should consider when buying the best kayak fish finder.

Your technical prowess

As technology keeps evolving, so do kayak fish finders. You will find them embedded with state-of-the-art features. But they are of no use if you do not know about their application and utility. If you are not tech-savvy, then better go for a simple kayak fish finder with essential features that you understand and can easily use. No point in wasting money on something you do not know of.

Personal comfort

Do not forget about your level of convenience when choosing the best kayak fish finder. If you have weak eyesight, then a large screen would be better suited for you. Similar personal considerations should be considered, like screen resolution, color vs. b/w, pixels, etc.


You would know where on under what conditions you would use your kayak fish finder. Will you use it on a boat, canoe, cabin cruiser, etc. The water bodies like lakes, rivers, lakes, ponds, etc., would also affect kayak fish finders’ choice. Lastly, conditions like icy, muddy, fresh, salty, shallow, deep water would also determine which type of kayak fish finder you should go for.


A transducer is integral to any kayak fish finder. It throws out signals in the water and receives them back with information about what lies beneath the water. Its quality and mounting capability would directly affect your kayak fish finder, so choose accordingly.

Transducer materials

Transducers come in several materials ranging from plastic to bronze. Each type is meant for a specific kind of boat and fishing condition. For an occasional angler, a plastic transducer would do well. Their mounting capabilities, like in-hull or through-hull mounting, are essential too. These two types of transducers come with plastic housing. For boats with wooden or fiberglass hulls, a bronze or stainless steel housing would be perfect.

Cone angle

A cone angle is very crucial to the ideal working of a kayak fish finder. The hook and width on which a transducer sends the beam to determine its capability. The wider the angle, the better will be its capability to detect fish underwater. The angle range can vary from 9 degrees to 60 degrees. For an average user, a 20-degree angle would suffice. 

Number of beams

Just like the angle, the number of beams is also essential. A typical transducer sends only one ray, but there are dual-beam and triple beam transducers as well and even with side beams. The higher number of beams makes it easy to navigate large water bodies and detect more catch in the process.


It is another helpful feature that most, but not all, kayak fish finders have. It would be best if you looked for the one that has this feature. This is because GPS gives you several benefits. You will be able to download maps of different water bodies and their topography, you can easily mark your waypoints and even go for customization in maps.

Bluetooth and Wi-Fi connectivity

They are both convenient features to have on a kayak fish finder. It allows you to connect to various devices, share, exchange, transfer data, and information, and use it for future reference. 

Power source

The power supply also plays a vital role in the working of a kayak fish finder. A kayak fish finder works by converting sonar waves from the Transducer. It will require more power when fishing in deep waters and less energy in shallow waters. The more power it has, the more powerful will be the sonar waves resulting in better and accurate underwater reading.

Level of frequencies

Kayak fish finders work with transducers on multiple frequency levels. These frequencies can be 50,83,192, or 200 kHz. Shallow water fishing will require higher-frequency transducers, while lower-frequency transducers would go well for deep water fishing.

Water resistance

Water resistance of transducers also affects it’s working. Look for IPX or JIS rating for water resistance on the transducers. A less than 5 rating depicts water resistance only from splashes of water. A more than 5 rating means a medium to a higher level of water resistance.


Whether you need a portable or fixed kayak fish finder would depend on where you would fish, what type of boat you use, and your fishing frequency. For kayaks, small boats, a fixed kayak fish finder would work well. For someone doing frequent fishing or land-based anglers, a normal portable fish finders would be acceptable.


CHIRP means Compressed High-Intensity Radiated Pulse. It is a valuable technology where a spectrum of frequencies is sent underwater continuously. This results in more clarity and accuracy in underwater exploits. So it is a good idea to go for kayak fish finders with CHIRP technology.

Imaging technology

Modern kayak fish finders now have side and down imaging technologies. These are valuable tools to see what lies underneath your boat and on the sides. They can be used simultaneously for better results. So opt for kayak fish finders that are equipped with this technology.

Other considerations

Besides the above other factors to consider can be cost, brand, durability, warranty, personal choice, etc.
