The 7 Best Kayak Fish Finders in 2021
1. Garmin Striker 4 – Best Overall Kayak Fish Finder
If you are going to fish in deep water or saltwater, Garmin Striker 4 will help you do this with ease as it features the CHIRP sonar technology. The CHIRP sonar, unlike the traditional sonar, emits a continuous range of waves so that you can see down to 1600 feet in freshwater and 750 feet in saltwater. Moreover, the CHIRP technology helps you distinguish between the cluster of fish and small targets, and offers clear images.
Besides, it features a double display ability that allows you to check the waypoint map and reader on the same display at the same time. You can also view the 77 and 200 kHz signals at the same time for a fuller underwater reading.
Having the ability to choose from a device with a 3.5, 5, and 7-inch display sizes is excellent because you can select a display size that suits the size of your kayak. You will also enjoy its 480 X 320 resolution that displays crystal clear and sharp information and images on its full-color screen.
It comes with a standard transducer that you should mount on a transom arm that you will also find included in the package.
Furthermore, you can use this babe in harsh weather because it is IPX7, so it can pretty much stand any weather.
Besides, this is the best kayak GPS fishfinder because its GPS is extra accurate as it uses two conical beams when it is detecting fish so that it pinpoints a wider surface area. It also has a waypoint map so you can navigate and also mark locations. Why is the ability to mark locations extra great? It is essential because it saves you the time you would otherwise spend searching for the perfect fishing spots you have come across before.
However, some users complain about it not having maps.
- Can be read it in bright light
- Excellent resolution
- CHIRP sonar
- Comes with a battery
- No Maps function
- No MNEA connectivity
To say the least, this is the best waterproof fish finder. Get it if you need a fish finder that you can use in any weather. You can also get it if you need a fish finder with high resolution and one that can be read in sunlight.
2. Deeper PRO+ Smart Sonar – Runner Up
The feature we most admire about Deeper PRO+ Smart Sonar is that it helps you find the greatest fishing spots because it lets you tie it with the fishing line, cast out, and receive a scan of the area lying between you and the end of the line. By doing this, you can detect the perfect direction to cast, how far to cast, and also determine the depth of the fish in certain places.
Moreover, Deeper PRO+ Smart Sonar is the perfect castable fish finder that is also lightweight, portable, and wireless. Whether you will be shore fishing, ice fishing, or boat fishing, it won’t let you down. It can scan down to 260 feet and can make up to 15 scans per second.
It is also easy to start, given that you will only need to place the pod in the water and sync it easily with Android and iOS devices via Wi-Fi hotspot. It is okay if you are not a user of any of these because it works with all platforms (yay!).
Customers don’t like its battery that only lives for 5.5 hours if you use it continuously. Moreover, it is very kind-of-heavy weight means that you must use a stiff rod to cast it. However, we believe that its other features make it one of the impressive portable fish finders for kayaks.
- Covers a wide area
- Must be used with a stiff rod
- No CHIRP
- Short battery life
If you want a castable fish finder, this babe is for you.

It is especially great for beginners because it makes an alarm whenever it detects fish. Moreover, it is super simple to use thanks to its three user-friendly modes. Among these modes, there is the Ice Mode’s digital flasher that makes this device usable during all seasons. You can even use it while you are ice fishing.

It also has FishArc and FishID fish finder indicators that target the fish depth and HD bottom landscape imaging. It has a long battery life of about 20 hours.

Why Is It Important To Mount a Fish Finder On Your Kayak?
Having an Eye Underwater
Whether you fish to sell or for fun, being able to see what is underneath the kayak is always a huge plus. You have no idea how many underwater structures you’re going to discover with a fish finder. Some people object to this by saying that they are going to spook the fish in this area. To be honest, there is a possibility this could happen; however, you can always mark the spot and get back to it later.
Moreover, a fish finder can detect the holes and canals that may be full of fish, and you would never know without a fish finder. What a loss, right?
Marking Spots and Finding Your Way Back Home
Most fish finders have a GPS. Given this, you can easily use it to mark the best fishing spots you come across so that you can go right to them on your next trip. Moreover, fishing with a kayak helps you get to places that other boats or ships can’t get into, and that increases the possibility of losing your way.
Since it is a nightmare to find yourself lost in the sea, a fish finder can track all the places you go to so that you can follow them and return to the site from where you have started the trip.
Yes, you can use the GPS on your phone to do this, but it is nicer and safer to have a waterproof device that has a durable battery.
Having a Versatile Device
A fish finder is mainly used to detect the fish structure and place, but it can do a lot more than just that, like marking fishing spots and helping you find your way back home. Moreover, some fish finders detect the water temperature and detect fish even when you are ice fishing. It can also help you find seamless routes for a more enjoyable trip.
How to Pick a Fish Finder
1. Mounting Space and Portability
Again, since the kayak is small, you must, before buying a fish finder, check where you are going to mount it on your kayak. Make sure you choose a place where you can easily access the fish finder and a place that does not get in your way when you are fishing. For example, let’s say you need to get a device with a large display screen, check first if the kayak is going to be able to accommodate such a big fish finder.
Besides, getting a portable fish finder enhances the ease by which you can check the information since it is a bit of a hassle to hold a fish finder with one hand and paddle or throw the line. On the other hand, some fish finders allow you to connect them to your mobile phones via Bluetooth, for example.
2. Screen Size
Of course, having a fish finder with a bigger screen size will allow you to see the information with more detail; however, you won’t like it if you get a fish finder with a size that doesn’t go hand in hand with the size of our kayak. So, if you have a small kayak, 3.5 to 4 inches of screen display would be great. If the kayak is not very small, you can go for a 5-inch screen display.
It is needless to say that the higher the resolution, the better the quality of the display screen. If the resolution is good enough, you will be able to see detailed images and know exactly where the fish are. Stay away from any fishfinder with a resolution lower than 240 × 160 because it won’t be clear enough; however, 640 × 640 and higher is an excellent resolution. Yet, you must know that the higher the resolution, the more costly the device is.
Each fish finder has a specific depth range. You must decide how deep you will be fishing to pick a device that suits you. Also, decide if you are going to fish in a lake, in the ocean or a river, because each of them has a maximum depth.
Having a fish finder that can detect fish that are so deep down in the water will definitely help you find more fish.
The higher the power of the fish finder, the faster it displays the information on its screen. Opt for a fish finder with high power if you are going to fish in deep water or saltwater; however, if you will only fish in shallow water, then you won’t need a device with so much power.
If you think that it is better to get a high-powered device regardless of where you will fish, I must inform you that this means that you are going to pay extra money in vain.
It is a critical part of the fish finder as it sends sound waves into the water. It is very much related to the cone angle because the waves it transmits are cone-shaped. Such waves enable it to display what is going on underwater onto your display screen.
Logically, the wider the beam width, the more you will be able to see. They usually vary between 9° and 60. A 20° cone angle is the ideal angle for all depths.
High frequency helps you receive more detailed images on the screen. High frequency means that more sonar waves are getting into the water and received from the transducer. The frequency you opt for is also dependent on the depth you will paddle in. For example, if you are fishing in shallow water, go for a frequency between 192 and 200 kHz, and if you go in deep water, a lower transducer of around 50 kHz will do.
Frequently Asked Questions:
What Is the Best Place to Mount a Fishfinder and a Transducer On a Kayak?
