A good fishfinder can make the difference between a so-so day on the water and one that makes the record books.
However, there is often the misconception that fishing with a fishfinder is incompatible with fishing from a kayak.
Sure, you may be fishing in shallow waters where it’s easier to see the bottom. However, fishing with a fishfinder can lend you several serious advantages.
If you haven’t already installed a fishfinder on your kayak, it might be time you did.
Using a fish finder on a kayak isn’t like using a fish finder for other fishing styles (like ice fishing).
In fact, there are certain products that are useful for ice fishing in particular.
In this article, I will tell you all about the benefits of using a fishfinder while kayak fishing, and I’ll also give you some suggestions as to my favorite products.
Here’s what you need to know.

Why You Need a Fishfinder For Your Kayak
1) Helps You See What’s On the Bottom
From feeding fish to structure to channels or holes, a fishfinder is crucial if you want to be able to see what’s on the bottom.
Knowing what lies beneath will help you have a better understanding of how deep your lures should be, how quickly you should be paddling, and whether it’s even worth your time to fish in a certain area.
2) Lets You Find Bait
If you are a skilled angler, you don’t just go after the fish – you go after what the fish are going after. When you know what your prey is looking for, it will be easier for you to find your target fish.
Find the bait, and you’ll find the fish – isn’t the how the old adage goes?
A fishfinder helps you rule out fishing spots where there is no bait, allowing you to look elsewhere for active fish.
If you find large schools of bait with your fishfinder, there’s a good chance that fish are waiting nearby.
3) Allows You To Navigate and Mark Your Spot
One of the handiest features of modern fishfinders is their ability to mark spots and plot a course.
You can even save a spot to come back to later, as the GPS will track your course and leave a trail programmed into the device.
Sure, you can always use your cell phone. But wouldn’t it be easier to have a device that does this automatically for you?
Plus, unlike your cell phone, a fishfinder is waterproof. No more worrying about dropping your expensive iPhone to the deepest depths of the lake! Fishfinders also have a lot better battery life than cell phones.
4) Shows You Habitat
One of the most helpful features of a good fishfinder is its ability to show you underwater structure.
As you likely already know, underwater structure – particularly structure of size – will hold fish at just about any time of the year.
When you find good habitat, you’ve essentially found the perfect spot to fish in. An underwater fishfinder will show you where the habitat is.
Since most fishfinders come with mapping technology, you can often mark these for further research when you get home, too.
Whether it’s a fallen log, an old shipwreck, or simply a rock outcropping, knowing where habitat might be is one of the most helpful features of a fishfinder on a kayak.
5) Displays Temperature
Sure, you could just look up the temperature on your smartphone.
But what if you don’t have cell phone service or if your weather app is simply unreliable? Plus, your smartphone is not going to be able to show you the temperature of the water.
If you invest in a fishfinder for your kayak, you will not only be able to detect natural features like spring-fed creeks and underwater currents, but you’ll also get a better idea of how the water temperature impacts the movement of fish.

How To Use a Fishfinder on a Kayak
When it comes to kayak fishing, though, you need to get more creative. Most fishfinders are designed to be connected to a 12-volt marine battery that is enclosed in a waterproof box.
When you’re kayaking, this kind of space is simply not available. Therefore, it’s important that you select a portable battery-powered fishfinder that will transmit data back to your fishfinder.
You also need to consider how you will mount the transducer. Most fishfinders come with instructions on how to do this, but you’ll have a variety of options.
The easiest way to attach a fishfinder to a kayak is to pass the transducer through the hull via the scupper holes.
If you have an older model of kayak, this might not be an option – therefore, you will want to find a fishfinder that works with the layout of your existing kayak.
No matter what, make sure you consider your fishing style and personal preferences in order to find the best fishfinder.
But remember that no matter what you choose, you really can’t go wrong when using a fishfinder for kayak fishing.
