In this article we will answer some of the most important questions and look at some of the best fish finders for kayaks that are available. Hopefully this will give you a better understanding of your needs and the types of products available for kayaks.
What Is A Fish Finder?
You may want to know what a fish finder is and what exactly it does before you decide whether or not you need one. First of all, a fish finder is a device that allows you to locate fish. It uses sonar technology to detect the pulses of sound and movement from fish under the water.
Fish finders feature a screen that lets you see where in the water your fish are. Some of them will allow you to see deeper into the water than others, but they will all give you a location that is best for fishing. This basically prevents you from casting into empty water.
Why Do I Need One?
If you’re planning on using your kayak to go fishing it might be a good idea to invest in a fish finder, as it will not only save you time in searching for fish but it will improve the likelihood that you’ll actually make a catch.
By showing you on a screen where the fish are located, you may have a more enjoyable and productive fishing trip. A fish finder will also give you the extra technology to be able to determine where there are underwater grasses or weeds, so you can avoid getting your fishing line or paddle caught.
Fish finders give you a better understanding of the underwater world and allow you to navigate through the water better. The technology also means you are able to locate and catch fish that you wouldn’t otherwise be able to see.
With a fish finder you have an advantage over the fish, as you are able to see them before you cast your line, meaning you can see them before they are made aware of you.
The transducer on a fish finder is the part that determines what is under the water, be it fish, vegetation or landscape. It is this part that sends signals to the display unit to let you know where the fish are and how deep the water is, so it needs to be under the water.
It uses sonar technology to communicate what it can detect under the water. This means when you’re mounting it, consider that it can detect bubbles and movement from a trolling motor or pedal drive. So it should be positioned away from these.
Fish Finder Features To Look Out For
When you’re choosing a fish finder for your kayak, you’ll notice that they are available in many different shapes and sizes. But for a kayak you’re going to need one that is more compact than the types you might see on larger boats.
Many of the fish finders will require some type of mounting to your kayak but it’s also possible to get a fish finder that can be held in your hand. This uses floating sensors to send the signals back to the handheld screen.
With the advancement of technology there are now fish finders that you can pair up with your phone. Many of them connect via Bluetooth to an app on your phone, so instead of having a separate screen, the signals and fishing data are sent to your phone.
There are fish finders available that will let you catch fish in all sorts of underwater environments, from lakes and rivers to the open ocean. So, when you’re choosing a fish finder for kayaking you should take into account where you’ll be using it.
There is no point having a fish finder that can detect fish 220 feet under the water when the lake you’re fishing in is only 40 feet deep. For sea kayaking, a fish finder with a deeper depth may often be of better use than when fishing in rivers or shallow lakes.
A fish finder will be able to tell you the depth of the water that you’re currently in and the various depths of the underwater landscape in your immediate vicinity.
With fish finders you need to keep in mind the power of the sonar and the frequencies that it can operate between. The higher the frequency, the shallower the water you can fish in.
This is because the higher frequencies are more accurate, so when you’re in a shallower area of water, the high frequencies will allow you to potentially catch more fish.
A lot of fish finders can operate on dual frequencies, giving you a balance of low and high frequencies for a wider range that can help you locate more fish in more environments.
Another thing to look out for is the wattage of the transducer. The transducer is the part of the fish finder that essentially finds the fish. It is the device that uses the sonar technology to receive signals and then send them on to your screen.
One way to mount a transducer!
If the fish finder has a transducer with a higher wattage it will be able to work quicker and locate fish faster. A higher wattage also means it will be quicker to transmit the data to your screen as you move through different depths of water.
You’ll notice when you’re looking for fish finders that there are a range of products that are aimed at different environments. There are some that are only for freshwater fishing or only for saltwater. So you need to decide where you’re more likely to use it.
However, there are fish finders out there that can be used in both saltwater and freshwater, giving you more flexibility over where you fish. Some fish finders will also be able to do more than just tell you where the fish are hiding.
There are various features on fish finders that will make for an easier fishing trip when you’re out kayaking, lessening the need for other equipment and letting you save some space.
Most fish finders will be able to detect underwater hazards, as well as fish, as the sonar technology bounces off of rocks and lets you see the structure of the land underneath the water. They will also be able to show you underwater plants and grasses.
Some fish finders will tell you the temperature of the water you’re paddling in, so you have a better idea of what the conditions are like to improve your chances of catching fish. Some are also designed for ice fishing, so you are able to see the fish beneath the surface of the ice.
You will find that there are a lot of fish finders on the market that have additional selling features, such as high definition color screens that you can easily see in bright sunlight or low light. Having built-in GPS can also be a good feature to look for.

How To Power A Fish Finder In Your Kayak?
To keep your fish finder running in your kayak you will likely need to consider using a 12 volt battery. Depending on the amp hours on the battery, you can power your fish finder for several hours.
If you plan on having your fish finder on all day you might want to think about a higher amp hour rating. For a typical all day fishing trip, a 10 to 20 amp hour battery might be ideal. But if you plan a shorter trip of just a few hours, you may be able to use a battery with a lower amp hour rating.
What’s The Recommended Way To Mount It?
Your kayak may already have a dedicated spot to mount your fish finder. But if not, you can mount the display unit to your gear tracks or you can mount it elsewhere on your yak in your preferred spot where you’ll most easily be able to see it.
When you connect it to your battery, you’ll probably want to make sure the wires are out of the way. One way is to have the wires running through the hull, which may require drilling a hole into your yak but you may want your battery to be stored inside the hull too, which can help keep it safe and dry.
How Do I Connect And Mount The Transducer?
The transducer needs to be in the water and one of the ways you can mount the transducer in through a scupper hole. Depending on your yak, it may have a dedicated transducer mount, especially if it’s a fishing boat.
There are certain products that can attach to your gear tracks to let you mount your transducer, meaning you shouldn’t need to drill any holes in your hull.
You will have to connect the wires from the fish finder to the connector points on your battery.
You can also mount the transducer through the scupper hole using PVC pipe and drilling holes through the pipe in order to secure the transducer. However, you would need to make sure the wires are running through the pipe before you secure it.
