Reading fish finder

Fish finder can be an excellent tool for anglers to locate fish schools quickly and effectively. The fish finder allows you to obtain detailed information about the underwater temperature, depth, etc. It also indicates the number of fish, school of fish, species, etc.


A common challenge faced by most beginners is to understand how to read the fishfinder screen correctly. Here, we will show you exactly how to read the fish finder and explain the results to improve the success rate of fishing.


Through the fishing probe, different sediments on the seabed can be determined. When the ultrasonic wave hits the seabed, it will form a strong echo, showing a red or brown line on the display. When you are out fishing, you will notice that the thickness of the seabed displayed on your fish finder will vary according to its hardness and composition.


 The part of the seabed displayed on the screen of the fishing probe is sometimes referred to as the "seabed wake" or "seabed zone." If the echo from the seabed is strong, the thickness of the seafloor zone displayed on the fishing probe will increase. This means that the seabed is very hard and is likely to consist of bedrock or reefs.


For the soft seabed, the situation is just the opposite. When the seabed is very soft, the echo will be very weak, and the "seabed" will also be very thin. When the echo is weak, the seabed may be composed of sand or sand.

The display of seabed thickness also depends on the operating frequency of the fishing probe. Generally speaking, the "seabed zone" displayed using low-frequency ultrasound will increase, and the "seabed zone" displayed using high-frequency ultrasound will decrease. If you want to clearly understand the seabed on your fishing probe, it is recommended to set the fishing probe to 50kHz, which makes it easier to judge the properties of the seabed.


 For example, when fishing for groupers, it is important to judge the nature of the seabed, because this type of fish tends to appear in rocky bulges.


Seabed


The rocky area on the seabed will produce strong echoes, which appear on the display screen of the fishing probe as a fairly conspicuous thicker seabed zone. On the contrary, when the seabed is soft, it will show up in very thin lines. This is because the seabed absorbs most of the ultrasonic waves emitted by the fishing probe.

The image on the screen of the fishing probe is the result of the echo returned from the seabed through the sensor, and is finally transmitted to the screen after receiving processing and image processing by the fishing probe. According to the different echo intensity, the color on the screen will change accordingly. The stronger the echo, the darker the color.


The echoes from the underwater school of fish are displayed in the order of time received by the fishing probe. The incoming signals move from the right to the left of the screen in an orderly manner.

The data setting on the screen moves from right to left at a constant speed. The movement speed can be adjusted.

Usually, when fish are found on a fishing finder, these fishes appear in groups. These schools of fish show great differences when displayed on the screen. They are shaped like fluffy clouds, towering thunder clouds and some thin and fuzzy structures.


This cloud-like pattern depends on the type of fish, their behavior, and how the school of fish swims in the water. The display images of a fish and a school of fish on the screen are also very different, and even novice fishermen can easily distinguish them.


For example, sardines tend to gather together to form a very large and compact school. These schools of fish will be displayed accordingly, and the large area and dark color indicate that the schools are dense. Mackerel and sardines are at different depths, but the way they clump together is very similar. Although the shape and size of the school of fish formed by different species of fish vary greatly, the fish probe shows that they are all uplifting.

Fish that act alone are easy to identify because they appear to be a very obvious boomerang or half moon shape.


High-density fish school-the echo is strong, the larger the fish school area displayed on the screen, the more fish there will be.

The same fish school, the deeper the depth, the larger the fish school’s display area


This is because the emitted wave expands wider as the water depth becomes deeper, and the echo expands wider as the water depth becomes shallower. Therefore, the deeper the water depth, the wider the display width of the fish on the screen.
