Best Kayak Fish Finder Buying Guide

Finding the perfect fish finder for your kayak can be hard work, but the products that we have looked at above are some of the best options on the market.

If you still aren’t certain which is the best for you, we’ve put together this quick buyer’s guide to help. So if you want to find out more, then keep on reading.

Mounting Style 

The first thing you need to consider when buying a fish finder is the type of mounting style that it has.

There are a variety of different methods that you can use to mount your fish finder to your kayak, to identify the one that is right for you, you should sit back in your kayak and take a look at where you have available space. 

The most common places to attach your fish finder are to the rudder, on the hull, or in the scupper holes. All of these different options are fairly simple to do, but ensure you choose the one that works best for you to make sure you will be able to enjoy your time fishing. 


Next, you need to think about the transducer. The transducer is probably the most important part of the fish finder as it is the component that allows the device to locate fish.

There are three main types of transducer that you may encounter: cone angle, sonar type, and frequency type.

Cone angle transducers are one of the more basic designs as they can only cover a certain amount of water at any one time. Sonar type transducers come in lots of different varieties, but they all use sound waves in order to locate fish and other obstructions beneath the water’s surface.

Finally, frequency type transducers use frequencies to locate fish below the water and plot them on your fish finder.

All of these transducers are excellent, but you need to consider the one that works best for you and the area that you fish in before buying. 


Following on, you need to consider the display of the fish finder. The display is often overlooked, but this is very important as it is what you will use to locate the fish.

When it comes to display, there are lots of different things which you need to consider, including screen size, resolution, and color display. 

Generally, you will find that most fish finders come with a display screen measuring 3-inches, but if you want a larger display, you can get models with a screen measuring up to 5 inches in size.

Similarly, you will find that the average screen resolution for a fish finder is 640 x 640 pixels, however you can get them with less or more pixels depending on how much you are willing to pay.

Finally, you need to consider whether you want the display to be in color or black and white. Color often makes it easier to locate the fish, but black and white models are cheaper, so you need to consider which is best for you. 


Something else you should consider before buying a fish finder for your kayak is whether you want it to come with GPS pre-installed or not. These devices tend to be considerably more expensive, but GPS takes your fish finder to a whole new level.

Kayaking can take you to a variety of different places, especially if you are on a river or active bed of water, and a GPS system can make this safer as you will always be able to find where you are.

This system can also help you save locations where there were lots of fish activity for future reference. 

Water Depth 

Before you buy anything, you will also have to think about water depth. This will be more important if you plan on going fishing in your kayak on water that is incredibly deep, such as the sea.

Deep-sea fishing is a very popular type of fishing, so this is a valid thing to consider when purchasing a fish finder.

If you are interested in this type of fishing then you should think about buying a fish finder which comes with a down-imaging unit as this will give you a much better idea of what lurks beneath the deep sea water. 

Smartphone Compatibility

Finally, you need to think about smartphone compatibility. This is something that is becoming more popular recently as smartphones can provide a back-up for your fish finder.

Fish finders are excellent, but their batteries are often very poor and can run out of power very quickly. If you purchase a fish finder that comes with smartphone compatibility then you will be able to back up all the information on the fish finder onto your cell phone.

This means that when your fish finder runs out of battery, which it inevitably will, you will still know exactly where you are, and more importantly, where the fish are because it is all stored on your phone.

This might not always be important to you, but if you regularly kayak in unknown areas then it might be a good idea for you to purchase a fish finder with this capability.
