Whether you are a serious angler that chooses to fish from a kayak or just a person that loves all the latest gadgets, check out what I found to be the best kayak fish finders out there to make finding fish easier.

Why Do You Need A Fish Finder?

Honestly, I do not know that we Need a fish finder, but for those dedicated anglers, or those techie guys that just like gadgets, maybe they just really Want a fish finder, LOL.

Although, here are a couple of reasons you might think you need one.

  • Finds the fish, so you don’t waste your time trying to find them the old-fashioned way.
  • May help keep track of the good fishing spots
  • Helps to determine how deep the water is and temp.
  • GPS, in case you get lost on the lake

If you are fishing in tournaments, a fish finder is probably a necessity. You have to be competitive and in order to keep up, you need to find the fish fast. Or, maybe you just like to work smarter instead of harder.

What is a Fish Finder?


The easy answer is just what it says, it finds the fish for you. I however, am going to explain it a little further for you.

A fish finder is a device that uses sonar (sound navigation and ranging) system to make a picture of what lies underneath your kayak or vessel that you are fishing from. They can detect everything under the water within its range from trees, bushes, the bottom of the lake or stream, and fish.

By pushing sonar waves down into the water, each time the wave hits something solid it bounces back and sends a signal back to the transducer, which then creates a visual on a screen to be read by the fisherman.

With todays technology they can also detect water temperature, and some come with a GPS function.

Just so you know, the links provided here are affiliate links. If you make a purchase through one of these links I may get a commission. It will not affect your pricing at all, but it does help me to provide you with the information you find here. So, thank you in advance.

Okay, now that the formalities are out of the way, lets get to it!

Hummingbird Piranha Max 4

When you talk about fish finders, one name that is sure to pop up is Hummingbird. Since their first fish finder developed in 1971, they have been a leader in the industry. They are imagined, engineered and manufactured in the USA.

The Pirahna Max 4 is a perfect example of their quality fish finders. The Pirahna Max 4 has 3 models available, but we are going to focus on their portable version.

I chose the Hummingbird PirahnaMax 4 PT due to the nice carrying case that it comes with. It makes it perfect for kayaks and canoes.

It sports a 4.3 inch screen with a tilt-mount base. It’s dual beam sonar has a depth capability of 600 feet. This little wonder incorporates the stylish features and functionality of their Helix series. All that in a portable little living space.

The PirahnaMax4 also has the FishID+, Fish Alarms, Depth Alarms and zooming has never been easier.

It also comes with a portable transducer and a 7Ah battery and charger.

Some key features are:

  • 4.3″ screen, with 256 color range and is LED back lit. It has a crisp 480×272 resolution
  • 2400 W PTP power output
  • 320′ Down Imaging
  • 600′ Duel Beam Sonar
  • Tilt-mount and swivel base
  • Convenient carrying case
  • Comes w/transducer

Unfortunately this one does not come with GPS capabilities, but do not let that stop you from checking this one out. It uses Unimaps and has an operating frequency of 200/455 kHz.

It also only weighs in at 2 lbs and doesn’t require much space. We all know that space is a premium in a kayak.

Garmin Striker 4

I know when we hear the name Garmin we immediately think of GPS. Well now we can get that wonderful technology of the GPS system wrapped up with their fish finder system. Two for one, nothing better than that.

The Garmin Striker 4 sports a 3.5″ color screen w/keypad operation and 480×320 pixel resolution.

This little contraption boasts the ability to work in saltwater as well as freshwater. The Chirp sonar can reach up to 750′ in saltwater and 1600′ in freshwater.

What is Chirp?

Chirp sonar sends a continuous sweep of frequencies, ranging from low to high, then interprets them individually upon their return as opposed to a single frequency like traditional sonar systems. Because the frequencies provide a wider range of information, Chirp sonar technology can create a crisper picture of what is in the water.

Not only can you find the fish with the Garmin Striker 4, you can also mark all your hot spots, docks and ramps. Never forget where you caught the big one ever again.

Some Key Features are:

  • 3.5″ color display w/keypad operation
  • Built-in, high sensitivity GPS
  • Chirp sonar and HD-ID sonar
  • Includes the Chirp (22/200 kHz) transducer w/transom & trolling motor mounting kit
  • Share way points with other Striker or Echomap combos
  • Smooth scaling depth-range adjustment
  • Includes tilt-swivel mount
  • Speed data displayed directly on screen
  • Shows current water temp

With all of this functionality in one little machine how could you go wrong? The Striker 4 also comes in a portable option with its own carrying case. That makes it perfect for us kayakers. Again, small and compact high function and very affordable.

Deeper Smart Sonar Chirp Portable Fish Finder

All I can say about this one is OMG!

This little bugger takes fish finding to a whole other level. Talking about technology all wrapped up in a tiny little living space. It’s kind of like letting the genie out of the bottle.

This little, castable, GPS-capable, Wi-Fi enabled fish finder utilizes the Chirp sonar technology and gives the average angler an edge over the competition. The Deeper Chirp connects right to your smart phone or tablet via a free app that is packed full of features and gives you real-time sonar imagery of what is happening in the water. This cute little green ball can also save maps of your favorite fishing spots for later via Lakebook, which is also free.

The Deeper Smart Sonar Fish Finder can detect fish as deep as 330′ or as shallow as 6″.

Not only is this a great option for us kayakers, but you can also use this from the dock or on shore. Talking about versatile!

Some key features:

  • Convenient, castable fish finder w/full-featured performance
  • Durable ABS enclosure
  • Connects to your phone or tablet (WiFi) up to 330′ away
  • Up to 6 hours of operating time and quick charging
  • 3 modes, standard, ice fishing, boat
  • 3 frequency Chirp scanning
  • Free app compatible with most smart phones and tablets

This is probably most high-tech little thing I have ever seen. It only weighs 3.2 oz. and will fit in your tackle box. It comes with big technology and some great features, sure to be a useful and fun device for any angler.

Are You Ready?

Are you ready to enter the world of high-tech fishing?

After my recent research about these fish finders I now feel a little more informed about what a fish finder is capable of and that they are useful for more than just finding fish.

I always thought that if you were using a fish finder that you were cheating and taking the fun out of fishing in general. I now know that even if you find the fish, the challenge is now to figure out what they are hungry for. Catching them is still a matter of figuring out what bait to use.

Also, I had no idea you could buy a fish finder the size of a large bobber. How fun is that?

Not to mention, with the models that offer GPS you will not have to worry about getting lost.

Well, I hope that I was able to provide enough information and options to help you make an informed decision about your next kayak gadget. Add some serious bling to your tiny boat and let’s get out there and catch the big one!

Maybe, you are just searching for that perfect gift for that kayaking fishermen or woman in your family.

Thank you for hanging out with me here at Kayak Adventures and have a Blessed Day.

  2. Hello there! Thank you very much on sharing this article on the best kayak fish finders. I’ve gone through the article and I must say I really did enjoy it as it contains valuable information. I actually didn’t know there was something called a fish finder, I used to go fishing with my uncle but I didn’t know about fish finders. I am definitely going to get one, the one with gps and no it doesn’t spoil the fun in fishing, it increases it. 

    • Hello Sophie,

      Thank you for spending some time and reading my article and leaving your input. I certainly think a fish finder can enhance your fishing experience. I am glad you found my article informative and helpful. If you have any questions, please don’t hesitate to come back and ask.

  3. This is really incredible! I know that technology is evolving every day, but I never knew that could think of producing a technical device use in finding fish even from long distance and the fact that It can even detect the water temperature and the way everything is underneath the lake. I am so pleased to know of this development.

    • Maureen,

      Fish finders have really evolved over the years. These ingenious devices are a wealth of information for the professional and recreatonal angler. 

      They have come a long way from the simplest fish finders to very high tech with multiple colors and functions. Much like our computer systems and cell phones. It’s hard to believe that you can even use your phone as a fish finder through the apps and the Deeper Sonar that I highlighted in my article.

      Thank you for stopping in and leaving your input. 

  4. Quite an interesting one to see here. It definitely does affect me positively and how you have shared this. I am a big time lover of kayaking and seeing this benefits me greatly. I like this Garmin Striker 4 features better and I can resonate well with it. This is really good and thanks for sharing with us

    • Thank you for stopping in and taking the time to read and leave your input. I think the Garmin Striker is probably my favorite as well. It has a lot of great features. Especially the GPS feature. I am not the best with directions and that feature would definitly help locate and remember the great fishing spots.

  5. Hello Annette, 

    For me going fishing is really fun and I have always engaged in it with a couple of friends where we sail deep into the ocean sometimes and fish. I have once made use of a fish finder and it was a pleasing experience making thongs easier and I really enjoyed the whole experience that day. Lately, the fish finder got bad and I have decided to search for a better one and I stumbled on your article which has given me options. 

    • Lawson, thank you for spending your time with me here. I am happy that you found my article and think it is helpful. 

      The fish finder market is a big one, but the ones that I have highlighted here are super functional, don’t take up much space, are user friendly and affordable.

  6. Thank you for this amazing post on Best Kayak Fish Finders. I usually go kayaking in the summer but soon get bored and return back. This could be a good idea to fish while you are out in the water. Your tips about fish finder would be super helpfull. I’ve been meaning to try fishing and this would be a perfect motivation if I get this fish finder gadget. If it okay if I share this with on my group. 

    • JN you should try fishing while out in the kayak. It is a blast! You can check out my post about fishing for beginners and discover a whole new way to enjoy your kayak.

      Even if you do not fish yourself, one of the fish finders in this review would make a great gift for someone you know who does.

  7. I honestly didn’t even know that they had stuff like this. I’m not much of a fisher… I’m not a fisher at all, lol. I went fishing once and I remember liking it, but not liking the mosquitos :(. I am a geek though, and I do like tech, so you got me there. Maybe If I had a fish finder, I would have been able to enjoy it more? Hmm, well, these are, like a lot of hunting equipment, quite expensive. I do wanna go bow and arrow hunting though, so maybe I’ll pick it up. 

    • Well Tech RVL, thank you for checking out my techie induced review or fish finders. I believe even those who have never fished, but like tech can enjoy a fishing trip if a fish finder is in the basket. They come in all price points and the ones I have chosen for the review are really great choices for all budgets considering their qualities.

      Besides, they are great for folks in tiny boats.

      I think you should absolutely take up an outside hobby, whether it is hunting, fishing, kayaking, etc. It is great for the soul.

      If, you know anyone that is into fishing, these great little fish finders make great gifts as well. Hope you have a great day and come visit often.

  8. You have written about two things I love.  I enjoy fishing.  I have a sturdy runabout that has a fish finder.  You are so right.  It helps find the fish where casting and moving the olde fashioned way took time.  The other thing I enjoy is kayaking.  A couple of days ago, I communicated with one of my kids about kayak fishing in an small lake not far away.  I have been invited several times to kayak fish in the ocean, but I dont have the nerve.  The idea of a portable fish finder for a kayak is new to me but I love it.  Thanks for turning me on to this idea.

    • Anastazja, I would not have the nerve to go in the ocean either, LOL 

      Fishing in a kayak is great fun, even without a fish finder, but if you serious about catching fish or at least fineing them, itwould be a great help. I personally really like the GPS factor that many of them provide. Nothing worse than being lost, LOL

      Not to mention they make great gifts for those friends and family that love to fish.

      Thanks for stopping in and reading and leaving your thoughts.
