What to look for while buying a fish finder for catfishing

Searching for catfish can sometimes be a long and demanding task, which makes using a fish finder a  sensible choice. As with any modern gadget, fish finders offer a lot of different features and options. Some of them are important and the others are not deal-breakers. To understand what to look for in fish finders when it comes to catfish fishing take a look at the points below.

Type of mount

This is the first thing you should pay attention to. Choosing the right type of device can make your experience a lot more convenient. There are three different types of fish finders from this perspective:

Mounted finders

Designed to be fixed on a boat or a kayak

Portable finders

Easy to hold and carry, convenient to use

Castable finders

Compact, versatile and don’t require a boat to be used

Transducer (Sonar)

The transducer is the fish finder part that’s responsible for sending out and receiving signals that are used to compose an image that is displayed on the screen. There are several different technologies on the market:

2D Broadband

These are traditional, old-school sonar that shows you the image of what’s directly beneath you. 2D’s offer less information than any other type of sonar.

Down Imaging

Down imaging technology is the evolution of 2D sonars, with the image composed from below you, but with greater detail and definition.

Side Imaging

Similar to down imaging when it comes to improvement in image detail and quality, but Side imaging sonars cover way bigger surface. It shoots the beam at an angle, also covering the area around the boat.


Fishfinders that incorporate GPS systems are very useful for finding catfish, avoiding dangers, and revisiting specific spots. In combination with topographic maps, they become second to none when it comes to navigating and finding big catfish.

Transducer frequency is also an important factor. We’d recommended a frequency range from 200kHz to 800kHz for shallow water use, and 50-100kHz for deeper water.


The accuracy of a fish finder is something that will make it very useful or almost useless when catfishing. Beams that cover wider areas are usually far less detailed, which makes them great for shallow waters, but not if you target greater depths. Many fish finders come with dual beams systems, and in that case, you won’t be limited by water depth as much.


As with most technological devices and gadgets, saving a couple of bucks on purchase can prove to be a more expensive option in the end. We recommend you stick with reputable Fishfinder manufacturers such as Humminbird, Garmin, Lowrance, or others from our list. With these brands, you’ll get support, a warranty, and more device reliability.


The price of a fish finder can go up significantly, depending on the features it comes with. Mounted or portable high definition CHIRP finders can cost even in the excess of $1000. Castable fish finders are usually more budget-friendly, starting at just about $100. We recommend you start with this type of sonar, before transitioning to high-end ones when you gain more experience.

Side Imaging fish finder for catfish

Side imaging fish finder is a useful tool, especially for catfishing. They differ from traditional sonars because they show a much wider picture of the water below you. Down sonars or 2D finders show a small area directly beneath, which would make it practically useless for scanning large surfaces with shallow water. They are excellent for exploring underwater structures such as logs, rocks, and others. In addition, they are also used for tracking down fish schools of shad or herrings, so you won’t have to waste time searching for the bait either. Finding big schools of blue catfish in the big lakes won’t be a problem with a side imaging fish finder.

Down Imaging Fishfinder for catfish

Down imaging is more detailed than older 2D technology.  It allows you to see what’s straight below your boat or a kayak. They are inferior to modern side imaging and 360 degrees sonars since the range is too limited. But you can definitely use them to catch catfish. You can even see them on the screen, usually as big arches. They will also show you shapes below, which is useful when searching for catfish hideouts.

How do you find a catfish with a fish finder?

You can use your fish finder to locate catfish, but it won’t be too easy. Fishfinders can never tell certainly what’s below you. You’ll see various contours and shapes on the screen, which makes mixing up a log with a catfish pretty easy. Since they are usually so vague, even if you guess right, and it is a fish, it may not be a catfish. So we generally recommend you use your fish finder to locate schools of blue catfish since they are easier to identify. The best way to find catfish with a fish finder is by observing the underwater layout, for potential catfish hiding places like holes, structures, steep depth changes, etc.

Tips for Using a Fish finder for catfish

Here are a few useful tips you should know, after purchasing your first fish finder for catfishing :

  • The first thing we would suggest you do after purchasing a fish finder is to open a manual and install it properly. Place the screen in a handy place where it will be safe from potential damage. Don’t mount the transducer too high on the haul, to avoid “cavitating”.
  • Read the manual and familiarize yourself with various options, images, and functions
  • Remember that even if the finder doesn’t show catfish, that doesn’t mean there is none there
  • Use the finder to learn about underwater layout, rather than chasing the fish itself. Underwater logs, holes, depressions, and steep ledges are ideal places for catfish.
  • If you find the spot you want to fish in, anchor slightly above and cast the bait down the current

Frequently Asked Questions

1. How can fish finders find catfish?

Fish finders find catfish by emitting a signal from its transducers. The signal travels through the water and bounces back when it hits an object. This reflected signal is then processed and shown as an image on your screen.

2. Will a fish finder pick up catfish?

Yes, fish finders can pick up catfish. But they won’t always pick them up, depending on the transducer strength and accuracy and water depth. Even if they don’t pick them up, it doesn’t mean there aren’t any there.

3. Do fish finders show catfish?

Fish finders can display catfish on the screen. They usually look like thick arches. The bigger ones are easier to spot, especially on traditional fish finders. Advanced fish finders show a more detailed image, so you’ll be able to identify them more easily.

4. What is the best screen size for a fish finder for catfish ?

When it comes to fish finder screens, it’s simple – the bigger the better. A large screen will let you see things and detail you’ve never seen before. Even if you have an accurate sonar, with a high resolution screen, it won’t matter unless it’s big enough to display all the information. We recommend you to go for at least 4in screen.
