What to Look For?

Fishing conditions are a priority and the kayak you are using as well as various other important factors can either make your fishing expedition a success or a disappointment. We will point out the essential characteristics of fish finders so that you have an easy time making a choice.
The main components of fish finders are a power source which is a 12V battery, transducer for sending and receiving signals into the water and the display; the unit itself with buttons and screen.

Power Source:

You need a power source to run wiring to the display and transducer, which is a standard 12V marine battery.


You need space for that too, and many kayakers or manufacturers like Lowrance offer a suction cup mount along with their device.


Everyone thinks a large display is better and for obvious reasons too. However, when you consider a fish finder, keep in mind that you are looking for something that will fit a kayak. The kayaks width is essential, and you do not want a massive, clunky device that adds weight and is difficult to mount. Display size is thus an important consideration.

In addition, you also have several other important factors to consider which are discussed below:

Mounting space

Mounting space is one of the first things you look at. It will depend on kayak size and space. You cannot choose a device if your fishing kayak does not allow for proper mounting of your chosen device.
Does your kayak have adequate space for the device itself, the 12V battery and its cables too? The larger the kayak, the larger you can go in screen size. A small kayak will do better with a smaller device with a 3.5-inch to 4-inch screen. 5-inch screens will be good when you own a large kayak.

Screen resolution

When you choose a smartphone, camera, TV, etc. you always look at the screen resolution. The same applies when you select your fish finder. More details, sharper imaging and much more can only be achieved when the resolutions are higher.

Down or Side Imaging

Some models use down imaging, while others use side. As you can deduce from the name, down imaging will show you what is below. Down imaging is therefore suitable for deep-water kayaking. Side, however, shows the side, which is suitable for shorelines and terrains, making it suitable for shallow fishing along the coastline.


Frequencies are essential as lower frequencies suits deeper waters, while shallow water requires higher frequencies. Single, multiple and dual frequencies are available as well. The frequencies predominantly range between 50 and up to 200kHz.

Weather Resistance

You want your device to withstand all elements. It is hardly ever a cheap device and protecting your investment is another priority.
A fish finder that can withstand what nature delivers on open waters, including priority one, water resistance is a must. Look at the design and opt for a rugged device.

Manufacturer and Price Ranges

The other priorities include a trusted brand from a reputable manufacturer. Some of the best fish finder devices are manufactured by brands like Garmin, Humminbird, and Raymarine.
These are high-end devices with a price tag to match. Budget-wise, you will also get good models with a lower price tag; just be sure you do not become a victim of being cheap since you will usually end up paying more in the long run in your quest to find a kayak fish finder that caters to your needs. All in all, nearly all these devices are manufactured with different budgets and needs in mind.
