How to Find the Best Fish Finder for Kayak Fishing

When we set out in our kayak for a day on the water, how can we better find those fish that have taken to deeper water? Those of us who are experienced anglers know the answer, the challenge that we have is finding the best kayak fish finder available.

That is why we have taken the time to assist you in this search. Here is a list of some key features you should look for in a kayak fish finder:

  • Size
  • Transducer
  • GPS
  • Power Source

This short list is simply from our cumulative experience, as it serves as a good “barometer” to get you looking in the right direction.


Do you need that large display mounted on your kayak to find the fish and premium coverage areas? No. Especially in an already tight area. The best fish finder for kayak fishing will have a screen size that is 5 inches or less


What are my options for mounting the transducer? Some of us use a suction cup, or inside the hull, or through the scupper hole. You will want to check for the type of mount that the transducer comes with, and suction cups are not necessarily the best route. Perhaps it will be one that can be cast out.


What are you favorite fishing spots? Are you fishing bodies of water where land is always visible? If you love to fish on open water where land is out of sight, you need a GPS. This is also beneficial for those who like to track their distance and mark certain spots.


Are you looking for a more well defined imaging of the fish and structure below? Older technology can show a school of fish as one large image, with CHIRP technology you can position your kayak where the action is with clearer imaging below the surface.

Power Source

Are you interested in placing a marine battery in a waterproof box and running the wires to the transducer and display in your kayak? Or, are you more inclined to go with a portable fish finder pack?

Lowrance 000-12635-001 Hook-3X Sonar, W/ 83/200 XDCR


How difficult is it to find the best fish finder for kayak fishing that is affordable yet efficient? Us anglers know the answer. Inevitably we have to sacrifice some features to spend less, and many times the features we sacrifice are essential ones to a productive day on the water.

One of the complaints that some anglers have is the need to constantly adjust the settings to more clearly see fish and structures. This Lowrance model uses Advanced Signal Processing (ASP), which will limit the time you previously spent trying to get a clearer image.

Size will not be an issue, as this model is 3 inches. The transducer comes with the necessary mounting hardware, as many customers have successfully mounted this unit on their kayak.

Signstek FF-003 Portable Fish Finder


Are you planning a trip to a river where trout are abundant? A popular method for trout fishing these types of water is using a float, or kayak, and paddling up or downstream for more solitude.

With the Signstek FF-003 Portable Fish Finder in your kayak, you can paddle to where the fish are. No mounting hassles for the display. The transducer can easily be cast into the water, as it comes with a float, or you can mount it to your kayak.

Many of us do not want the hassle of placing a marine battery in a waterproof box and setting it up in our kayak for a day on the water. This fish finder is powered by 4 AAA batteries.

While the 100 levels of sensitivity settings may concern you, bear in mind that this is to assist the user with clearer imaging.

Things We Liked

  • Does not require a marine battery for power, portable
  • Colorful, easy to read display
  • Precise depth readings
  • Transducer can be cast out or mounted to the kayak

Things We Didn’t Like

  • Mounting could be an issue, if you paddle with 2 hands and hang it from your neck it is virtually impossible to view while paddling
  • Transducer may require some modifications to get it to hang straight
  • No options for external power, so bring extra AAA batteries



So, we are looking for the Best Kayak Fish Finder. Each of the 5 options listed have their own unique features and benefits.

Each of them are small enough in size to work in a kayak. When it comes to the transducer, some of them come with one that can be cast out into the water, while others come with one that should be mounted to the kayak.

Our list narrows down when we look at GPS. We know the importance of this feature when we want to mark certain spots that have the coverage our fish of choice prefer, or if we get lost while on the water.

Only one of the 5 choices offers CHIRP, as this is the game changer for our decision of which of the 5 is the best. CHIRP technology enables the user to “see” what can not be “seen” with older down and side imaging systems.

Finally, the power source. The convenience that comes with a fish finder that is powered by smaller batteries, say AAA’s, is nice. Yet, are you willing to sacrifice quality?

Our decision on the Best Kayak Fish Finder is the Garmin 010-01550-00 Striker 4 Built-in GPS Fish Finder. It meets all of our criteria, and is offered in a portable kit for a small amount more. Customers have reviewed this product after use and rate it high. We are convinced it is your best option on this roundup for your kayak fish finding needs.
