How to read a Fish Finder Display Screen

How to Read a fish finder is most important because fishing is one of the best ways to enjoy the great outdoors. Fishing is a sport that anyone can do, but it takes patience and skill to be successful. No doubt it is a fun and nature exploring activity that can be enjoyed by all ages. It’s also an activity that you can do with your friends or family, so it has the potential to be a great bonding experience.

Fishing has been a popular activity for many years and it’s no wonder why!

Having so many different species of fish to catch is what makes fishing so enjoyable. You can try catching bluegill or catfish one day and then bass or trout the next. Fishing technology has been around for a long time, but it’s only in the last few years that we’ve seen a major shift in how fishermen are using their tools. Gone are the days of throwing out a line and waiting to see if you’re going to catch something.

I was fishing in the ocean when I noticed something flashing on my screen. It turns out that it was a school of fish, and I caught them all with ease! What’s more is that they were so close to me because my radar helped me find them.

Today, fishing is all about efficiency and precision. The latest trend in fishing technology is GPS systems for finding fish locations more easily than ever before. Fish finders use an electronic device called sonar which sends sound waves underwater to map the seafloor’s contours as it bounces back from objects like schools of fish or rocks below (source).


A Fish Finder can help you determine where the best place to cast your line would be, which will increase your chances of catching more fish. A lot goes into reading a fish finder display screen, so it’s important that you know How to read a Fish Finder Display Screen and what each feature means before heading out on the water.

The display screen makes it easy for any person to see what’s below them and help catch more fish. This blog post will go over some of the most common symbols and how they should be interpreted in order to get accurate readings from your device. Once finished with this blog post, you’ll never again wonder “What does my Fish Finder Display Screen mean?”

Fish Identification

On a fish finder you need to know how to identify fish first. Fish are not always visible, but the marine electronics can help you home in on them. Most fishermen rely upon their depth finders and side-imaging sonars for this purpose.

Learning what different shapes indicate will make it easier to discern between a school of baitfish and a big one.

Symbols of fish

In Fish-ID technology type of fish finder, fish icons are used to help identify specific species. It is a great tool for fishermen because they show up in your screen when you have the right kind of equipment, but without knowing what these images mean or how they differ from each other it would just seem like noise!

Each icon has been carefully designed so that at any distance and angle where an angler may look upon them while using their boat motor’s fish finding capabilities then there should always something recognizable about its appearance.

The Fish-ID technology is the greatest advancement in identifying aquatic life. It converts raw data into a user-friendly interface with little fish icons that often times represent different sizes. Some advanced Fish ID systems even have symbols denoting rocks, plants and schools of various species for those who need more information at their fingertips.

Arches of fish

The arch fish finders are one of the most popular types because they make it easy to spot large and small fish. They save time when using this type as you won’t have to go back through your list or search for them again, making sure that finding those elusive big ones goes up in an instant.


Coverage of Fish Finder Beam

A transducer with a wide beam covers large area but provides less bottom details. A narrow-beamed device will cover less of the ocean floor, but as you move closer to shore it can provide superior detail for studying structures and other features on landmasses below us such as beaches or mountainsides that we know exist beneath our feet because people have walked there before.

Judging of Fish Size

To read a Fish Finder it’s important to note the size of each arch because that can help estimate your catch. The thicker and wider they are, then a bigger fish is likely lurking in there.

If an arches appears empty near its end but has thick lines coming out from other sides this might mean something added such as fishing line which will make casting easier due to weight biases placed towards pulling up more baits rather than releasing them.”

The shape of an arch can also make a difference in how far up the screen you’ll see it. Bigger fish will have full, thick arches with well-defined curves whereas smaller ones are only seen as partial arcs that lack detail and depth when compared to larger species like Atlantic salmon or brook trout.

Fish thickness

When you find a fish, it will tell your depth and the kind of water with an echo. The more echoes there are in its signal – i.e., if they’re bouncing around on topsoil or bedrock- then this is due to how porous that bottom layer is beneath us; meaning we needn’t worry about sinking as much since what lies beneath isn’t quite so wet.

Underwater Structures– Identifying Different Types

The depth finder on your transducer is a great way to know how deep the water underneath you boat. It can also tell what type of fish are in that river, so it’s important for fishing!

The best part about them? Usually seen at top left corner with meters instead feet as its scale measurement .


Sonar is also a great way to help you find fish, but it can be even better with the integrated depth finder. This nifty feature will show how deep into water various objects are located so that when looking for stumps or rocks on bottom depths of 50 feet+, your search becomes much simpler.

The fish on the left-hand side of this photo is sitting in a small pool with an abundance of weed. It’s difficult to tell, but there are also other smaller ones below and between its scales!

It’s difficult to see what we’re looking at because there are many barriers in front, making visibility poor for 10 meters or so down into water depth where this outcrop sits before purple blooms appear again as if they were drawing curtains over themselves.

Colored Vs Darkest Fish Finder

When a fish finder with Colored transducers is used, the screen will display high and dark colors if there are powerful echoes. In other words, when it senses strong noise from beneath water or on land surfaces the darkest shade your device can produce without experiencing interference.

The Darkest transducers used, will encounter is what you get from the bottom of water. Not only does it go down sheer and deep, but also encompasses all those dark little crevices we never noticed before.

Depth finder


If you want to be able find what type of fish are in the water, then your best bet is by using an advanced depth finder. These types can tell how deep it goes below us and will give some insight into which species would live there or not.

Water temperature

The best way to find specific kinds of fish is using their geographic features. For example, some prefer warm water and others grow in cooler environments. Using just these two clues alone you can already start looking for the right kind with no problem.

Side Imaging and Down Imaging

Down imaging is a technique that uses the sonar cone to send an image of what’s right under your boat. It’s great for viewing things at close range, down in detail.

Side imaging is an underwater technology that uses two sonar cones sent sideways to the left and right of your boat. As a result, it helps you get overviews on either side of what’s going beneath or next in front.


Side Imaging (or ”side scan”) is a little more complicated. This scanning technique works from top to bottom and side-to side, while down imaging (or “down scan”) only goes right then left on the screen with your phone or tablet’s camera angle.


The Fish Finder Display Screen can be difficult to read at first. It shows a variety of information that may not seem relevant or clear. However, with some practice and guidance from an experienced angler, understanding this screen is easier than ever!
