Guys, but how do you read an Echo? Now let's try to explain it to non-professionals!

Are you just starting to use a depth sounder? You know the basics, but want to get more out of the fish finder? Not sure if you are reading the fishfinder display correctly? No problem, we're here to help. This short tutorial will teach you how to make sense of the sonar display so you can differentiate between a bait fish, a trophy, and just a submerged tree to get caught on. It only takes 7 minutes to follow this tutorial and by the end you will be able to read the sonar display for:

Fish identification

Fish size assessment

Identification of different types of underwater structures

And evaluation of the type and definition of the seabed

First, the fishfinders scan in cones.

Why is this important?

The size of the area being scanned will be affected by the angle of the cone. A wide beam cone scans between 40 ° -60 °, which means it will cover a large area. A narrow cone plumbs between 10 ° -20 °. So, make sure you know if the sonar uses a wide or narrow cone when looking at the data on the screen. Another point to remember about sonar operation is that it constantly sends and receives data, which means it flows continuously. The current browsing data is on the right: the further to the left it is on the screen, the older the data will be.

So, he remembers 2 points when looking at the sonar display: 1. Know if you are doing wide or narrow beam scans. 2. The screen scrolls continuously. This does not mean that the sonar is moving.

                           UNDERWATER STRUCTURES

Fishfinders are ideal tools for reading depth, seeing the shape of the bottom and identifying underwater features. Sometimes, this will be more valuable than the information that marks the fish. We observe the values ​​on the echosounder display to identify the underwater elements.

Before doing this, just remember two points:

1.The sonar plumbs constantly, which means that the sonar display continues to scroll even if the sonar does not move. If the fishfinder is stationary, the bottom appears flat even though it may not be. To get an accurate picture of the bottom shape, be sure to maintain slow and steady navigation.

2.The depth scale on the right of the screen allows you to define the depth of the element. The depth value in the upper right of the screen shows the depth of the bottom under the sonar at that precise moment. Remember that this is not necessarily the same depth as the features you just plumbed, especially if you are plumbing steep slopes or points.

These are extremely valuable items to use for a wide range of species, and the good news is that they are easy to spot with a fish finder. While trolling or rewinding the device, a change in depth profile appears - don't forget to use the depth reader on the display so you can monitor how fast the depth increases or decreases.

There are 3 tips that can help improve accuracy when looking for these items:

Once you have identified a steep slope, switch from wide-beam exploration to narrow-beam, then re-scan that area. This should provide a more accurate profile of the profile change and also ensures that you avoid "dead zones" in exploration.

Using the depth sounder to evaluate the type and reduction of the bottom

Whatever species you want to fish, knowing the lake bottom choice and texture is important when trying to crack the code and get the fish to bite. There are 3 factors to consider when trying to understand if the bottom appears on the echo sounder is hard or soft: bottom color, depth of the bottom, and the presence or absence of a 2nd signal in the bottom.

Usually the color scale helps in this enterprise, i.e. all color graded or grayscale echosounders use the color difference to mark the type of bottom, so for color models the lighter the bottom and the softer it will be. the darker it will be depicted the harder it will be, same thing for the models in gray scales but in this case the gradation of the color will be valid from the more intense and compact hard backdrop, to the shaded and less bright tones soft backdrop.
