Buying Guide: Fish Finders For Kayaking

If it’s your first time choosing a fish finder for kayak, you should consider a few things. Here’s what you want in a fish finder:

  • Look for a technically advanced sonar reading or at least the standard 83/200 kHz. Anything less than that won’t produce such great images.
  • Also, consider a unit that comes with a transducer. If it comes with a transducer attached, it will be much easier to set up.
  • Make sure it fits your kayak with its size and shape. Fish finders tend to differ in size, so check its dimensions before purchasing.
  • Regardless of whether you’re a beginner or not, look for a user-friendly display. This means things like waterproof housing, counteractive sun glare, split screens, smartphone integration, and different accessories.
  • Other additional features you might want to consider are bottom tracking, battery life indicator, and water temperature.

If you opt for a portable fish finder, you’ll get a few more benefits along with it. These are usually a bit more versatile allowing you to take them off when not in use. In most cases, you can sync it to your smartphone as well.

Regardless of whether you opt for the one that’s portable or not, make sure it fits your needs and preferences. Look for the right size, features, and specifications that can provide what you’re looking for in a fish finder for kayak fishing.

Kayak Fish Finder Features To Consider


Fish finders are popular units that make fishing much easier than ever. Still, they come in a wide range of styles, sizes, and shapes, and not all of them will fit your kayak. For kayak fishing, you should look for a device that’s more compact than the types meant for larger boats.

Most models require mounting although you can get the one that can be held in hands. Those use floating sensors that send signals to the screen you’re holding.

Portable fish finders are quite easy to find since the technology has advanced quite a lot. Those that are portable can also be paired to an app on your phone via Bluetooth. In this case, the signals and all the information are sent to your phone instead to a separate screen.


As we said, these devices range in features and specifications. They come with different abilities which make them suitable for different kinds of water and fishing conditions. This means you should consider the type of water you’ll use it in before you opt for a certain model.

For example, if you’re fishing at only 40ft of depth, there’s no point in having a device that detects the target at 220 feet under the water. Such depth would work better for sea kayaking, so make sure to consider these details when choosing one.

Also, look only for fish finders that can tell you the depth of water you’re in. Some models can also display depths of the water landscape near you.


With such devices, you have to think about the frequencies it can operate between. It’s also crucial you consider the power of the sonar it comes with. Those with the higher frequencies allow you to fish in the more shallow water.

Higher frequencies are more accurate which means they’ll allow you to catch more fish if you’re in a shallow area of water.

Many models can operate on dual frequencies which gives you a balance of both high and low. This means a wider range, more fish, and more versatile environments.

Make sure to consider the wattage of the transducer as well. It’s a critical part of your fish finder that pretty much does all the work of finding fish, so you want it to be powerful enough. It uses sonar technology to receive signals before sending them to the screen.


You may or may not need a versatile fish finder depending on how versatile is your fishing. If you’re always in saltwater or freshwater, you won’t need a unit that works in both.

Still, many models are quite versatile. They work in both saltwater and freshwater which gives you more flexibility and options on how to use them. Most of those can also tell more than just where the fish is.

Consider How Much Space

As we said, fish finders range in size among other things. Now, you know that kayaks aren’t the biggest boats out there, so it’s crucial you choose the one that will fit and won’t be in your way when you cast. It requires some mounting space, so think about how much of it your kayak has to offer.

You’ll need some space for a fish finder mount, a small battery, rods, tackle and cables among other pieces of your equipment. However, you don’t want a unit that’s too small either since that one will probably be difficult to read. Look for the one that’s compact yet easy to read.

Units with a 5’’ screens are usually the best choice since those are unlikely to get in your way when paddling. However, if you have a smaller kayak, you can even consider something with a 4’’ or 3.5’’ screen.

Final Thoughts on the Best Fish Finders for Kayak

At this point, you’ve probably made up your mind on one of these fish finders. These are among the best choices currently on the market, so it’s highly unlikely you can go wrong with either one of them.

Still, if you’re indecisive and cannot pick between them, we recommend you consider the Garmin Striker 4 with Transducer. It’s a reliable product that works in both saltwater and freshwater. It also comes in several display sizes to choose from.

Its features and specifications make this one stand out as one of the best on our list. However, make sure to consider your preferences and needs before deciding on a unit. It’s crucial that it suits your style of fishing, the size of your kayak and all other equally important factors.

Take your time and carefully think about what would make a good fish finder for you. We’ve reviewed some of the best, so it’s now up to you to choose one of them.
