Buying Guide: Fish Finders for Kayaks


There are some many great benefits of investing in a fish finder. Not only does it transform the way you fish, but also it will enhance your fishing journey and eliminate any frustration. If you invest in a kayak fish finder, you will be able to analyze both the depth and the structure of the bottom and easily identify flat areas below your boat. Moreover, it will be extremely easy to track down fish that is well hidden behind a rock or plants, and you can have all the important information that you need for your fishing, presented on a dual screen.

Important Factors

To begin with, you need to take into account your fishing needs and decide where you want to fish. If you do that, you will be well on your way investing in the best kayak fish finder that perfectly meets your demands.

Although fish finders are getting extremely popular and beneficial for anglers, you won’t be able to improve your fishing style unless you invest in a model that fits your needs. There is no One-Style-Fits-All because what might fit your neighbor might not be your ideal unit.

Keeping that in mind, you might be the one that prefers to fish on deep reefs, humps or weed-lines. If that is the case, then you should consider investing in a Down Scan Imaging fish finder with a GPS. The reason is that the GPS will guide you to your desired fishing location and the DI will identify rocks and other elements you need to be aware of.

Also, if you plan on fishing in large lakes or out in the open ocean, your best option is a GPS Combo because if there is a sudden weather change and visibility turns to zero, you need a unit that can safely guide you to shore. Keep on reading, and you will find detailed guidelines that will assist you towards the goal of obtaining the ideal fish finder that matches your fishing style.

On the other hand, if you are going to be fishing in shallows water like small rivers, ponds or small lakes, you don’t need DI or GPS unit, and a simple sonar  model is the way to go. The reason is that you if you are fishing in shallow water bodies, you don’t need to rely on GPS to guide you or DI to see the structure of the bottom.

Now that you have thought about your fishing needs and style, it is time to look at other important factors that you need to keep in mind before you fork out your money for a fish finder.


Display and screen resolution is among the most important factors to consider when you are deciding on a kayak fish finder. As you know, kayaks are very narrow, so there is very little room to mount a large and heavy 6-7 inch display that will probably get in your way more often than it will serve you.

You will be adding around 6-10 pounds to the weight of the boat if you mount a big display model on your boat. Moreover, by mounting a heavy item on the side of the kayak can be a dangerous act since you are basically shifting the weight and balance point of the kayak that any sudden or wrong move will flip the kayak over.

The size of the display is not the only important factor here because you need to take into account the screen resolution as well. A compact fish finder will serve you no good if you cannot read from the display. You will see that pixels are used to measure the screen resolution.

Therefore, if you want to get the most out of your unit, you should get a fish finder with a screen with the highest number of pixels possible to get all the important information you need in the best detail. Your absolute minimum resolution should be 240×160, but the amount of pixels that you can get can be as high as 640 x 640 or even higher.


Another important factor of a kayak fish finder is the transducer and what they will do is to send sonar signals to the water and analyze what is below your boat. Most, if not all fish finders that are sold today include transom mount transducer that you can easily install.

In addition to that, you need to consider the cone angle because a wider cone angle degree means more area covered below the boat. The cone angles can vary from 10-60 degree depending on the transducer. There are also options for those who fish in various depths of water,and for that angler, a 20 degree should be sufficient. The rule of thumb here is basically that you can cover more area with wider cone angle degree. However, keep in mind that a wide cone angle in very deep water might deliver less reliability.

Where to Mount the Unit on a Kayak?

Another important factor to think about before you invest in a fish finder for your kayak as the mounting space. You should have an idea of the space you need and the space you have available on your kayak to mount the fish finder. It is very beneficial to make enough space for the fish finder, cables, and a compact 12V battery pack. As we did talk about above, a huge 7-10″ screen might not fit your fishing style on a small kayak, but if you have a large kayak, that could be an ideal solution for you. On the other hand, those who own small kayaks should consider units around the 4″ mark.


Without power, the fish finder will be of no use for your and therefore it is essential for you to set-up a power source in your kayak. It doesn’t have to be a complicated setup, all that you need is a compact waterproof battery box where you can connect all the necessary wires from the fish finder to the battery.

However, if you are not willing to deal with cables and wires, your other option is to invest in a portable fish finder that includes a built-in battery pack and requires no wiring at all. Keep in mind that a unit with high power will operate significantly faster than a less powered unit.

There are so many fish finders for kayaks available on the market that include different bells and whistles that it might seem like a difficult task to pick one.
