Fish Finder For Kayak Buying Guide

A fish finder is a useful tool which will allow you to locate fish underneath the water, to help you find the best fishing spots. Fish finders use sonar technology to create an image of underneath your kayak and show fish and rocks. Fish finders have a screen showing anglers a picture of what’s underwater using special sonar technology.

The fish finder will emit signals that bounce off the objects underneath your kayak and then show you a visual representation. There are many different types of fish finders on the market, which vary in size and price. There are many small, portable fish finders available that are affordable, easy to use, and suitable for kayak use.

After purchasing a fish finder, you will have to mount it to your kayak, but it should come with all the necessary hardware to do so. Fish finders are waterproof, which makes them perfect for use in kayaks and boats.

While fish finders don’t provide 100% accuracy, they will help to improve your fishing and will hopefully help you to increase the size of your catch. It’s essential to choose a good fish finder, that’s suitable for use in kayaks as this will save you time and effort when fishing. Here are some of the things you may like to consider when choosing a good, inexpensive fish finder for your kayak.


Power Rating

Before choosing a fish finder, you should consider how powerful you need it to be. The fish finders’ power is measured in Watts. The higher the fish finder’s wattage, the faster it will be able to display the readings. A powerful fish finder will also be able to sense fish in deeper water. If you’re fishing in a fairly shallow river, you’ll be able to use a fish finder with a lower wattage. If you plan to go out to sea, where the water is likely to be deeper, you should choose a fish finder with a higher wattage.



The fish finder frequency will determine how much detail you can see on the screen. Fish finders that have higher frequency will provide a more detailed picture. A fish finder that has a high frequency will work best in shallow water and is suitable for use on a kayak. Products with lower frequency are best used for deeper water.


Screen size and resolution

As well as frequency, the screen resolution will determine the quality of the image displayed. Screen resolution is measured in pixels, the higher the number of pixels, the better the picture. If you choose a fish finder that has a higher screen resolution, this will allow you to see which items are underwater more clearly. A high resolution will make it easier to see the fish and to distinguish them from other objects.

The size of the screen will also affect the level of detail you’re able to see. Choosing a fish finder with a large HD display will improve the level of detail you can see. Screens also vary as they are either in color or black and white. Color is often better and easier to spot fish, as well as being more enjoyable to use. Colored screens provide better images and more detail.

However, colored screens often come at an extra price, and black and white will probably be adequate for fishing from a kayak.


Mounted or Portable Fish Finders

Before purchasing a fish finder, you should also consider whether you want one that is mounted to your kayak or portable. There are many advantages to both types of fish finders.

If you own your boat or kayak, you may want to invest in a fixed fish finder as this will be set up and ready to use at a moment’s notice. All you would need to do would be turn the fish finder on.

Portable fish finders are often more convenient and can be used on different vessels. This is great if you don’t own your boat or kayak and rent one instead. A portable fish finder will take up less space but is likely to cost more. It also takes more time to set up each time you want to use it.



Some fish finders have a built-in GPS that will tell you your location. It’s a good idea to buy a fish finder that’s GPS enabled if you are exploring unknown waters and are worried about getting lost.

A fish finder with no GPS will work just as well on a kayak as long as you know the river or lake that you’re fishing on.




There are many good inexpensive fish finders for kayaks on the market. Many of these are available for $100 or less. If you choose a fish finder with basic features, its likely to be budget-friendly and will suffice when fishing from a kayak.

However, you may also like to invest in a better quality fish finder with a larger screen that’s higher quality or with GPS. It all depends on your budget and how often you plan to use your fish finder.

A fish finder can help you to become a more successful angler and can help save you time and effort when fishing. It can also help you to increase your catch.

Good Luck!
