Pick Out The Best Fish Finders For Catfish

Anyone that has fished long enough knows that even the most faithful fishing spots will dry up from time to time. That submerged rock formation, weed bed or outcropping that normally always produces fish has inexplicably yielded nothing the last several times you have been there. So what do you do when your favorite fishing spots stop producing? The answer is you better have a good fishfinder on board to help you work way through this dry spell. This even applies if you are fishing for catfish too.

So what is the best fish finder for catfish? Catfish are pretty large so any fish finder with decent resolution should be able to spot them pretty easily.  

Every angler has their own preferences, but when it comes to the my personal choice is RAYMARINE DRAGONFLY 4 PRO if you want to catch that big catfish.  It is an excellent model fishfinder that has good screen resolution, multiple frequencies and the added bonus of having GPS navigation built into it too.

Key Charactiristics Your Best Fishfinder For Catfish Should Have

There are many different models of fishfinders out there in the boating marketplace. Some have fancy buttons and controls, some have nicely colored screens and others have weather radios built into them.

When the dust settles on the dressed up features of all these different fishfinders, there are really two key components that you must focus on in order to get that catfish dinner you have been craving.

#1 Screen Resolution/Size

To put it simply, it does not matter how many objects your fishfinder identifies in the water around your boat if you can’t tell what they are. That is what makes the screen resolution on a fish finder so important.

The size of the screen is important too. Even the best resolution on a fishfinder is useless if you have to strain to see the objects on your display because your screen size is too small. A display size that is over 4 inches is highly recommended here.

#2 Multiple Frequencies

We don’t live in a perfect world and sonar frequencies fit the mold nicely here. There is no such thing as a perfect sonar frequency because the waves they emit are impacted by the depth of the water you are in. Multiple frequencies will help you overcome these imperfections.

In general, higher frequencies give the highest resolution and work best in shallow water. Low frequencies are just the opposite. They work best in deeper water but the resolution gets worse the further down you go.

Reviews of Best Catfish Fish finders

Fishfinders are tricky items to purchase. It’s not like you can take them out and test them before you buy them. That is why we have taken the time to review three model fishfinders that will do a great job of leading you to catfish or any other type of fish you wish to go after.

1.  Raymarine Dragonfly 4 Pro Fish Finder Review – TOP PICK

Excellent daytime friendly display resolution

To be quite honest, there is not much that we don’t like about this fish finder. We consider it a do-it-all product that will allow you to search for and find many different species of fish.

The screen resolution on its 4.3-inch display is more than acceptable. The display on this unit is also nicely backlit so it can easily be seen under both day and night time fishing conditions. The display information can also be conveniently streamed to your smart device for easier viewing from where you are in the boat.

Its best feature is the dual CHIRP sonar systems it has. One CHIRP sonar system will allow you to spot fish from a distance and the other will give you much higher resolution images of what those fish are once you get close to that area.

The GPS feature on this product is great for way pointing areas you typically find catfish and for use as a navigational safety aid.


  • Excellent daytime friendly display resolution.
  • Dual channel ‘CHIRP’ sonar in two configurations.
  • The ability to stream data to a smart device.


  • No battery level monitor.
  • Owner’s manual could use some improvement.
