Fish Finder Down Imaging

Down imaging fishing is a very interesting field in fishing sport. It requires keen observation and some unique skills to be an expert at this sport. It is a fun sport as long as you are catching the right fish in an enjoyable time, however if you spend hours and hours doing it, it does not remain fun anymore.

Previously fishing has been known as a long time taking sport. Because it involved sitting beside the lake with the fishing lines hung in the water, waiting for the fish to get caught in the line. Most of the times you had d to go home without the fish because it just wasn’t a good day for fishing. however, this is not the case anymore. Now you can catch a fish in a very short period of time by detecting their exact location in the water. The device which enables you to do this is called the down imaging fish finder.

The fish finder can easily locate the fish from the underwater and can also give information about the other objects present in the surrounding. It does using the sonar waves. The waves are transmitted into the water and received back by the fish finder. The information carried by the waves is then displayed on the screen using images and graphs.

What makes a fish finder better than the other?

There are certain features on which the quality of a fish finder depends. A high-quality fish finder will give you more accurate representation of the underwater conditions and the location of the fish.

Listed below are the factors on which the quality of a fish finder depends.


The transducer of a fish finder is responsible for transmitting and receiving the sonar waves. The transmitted waves hit the objects deep underwater and are bounced back which are then again collected by the transducer. The information is then displayed on the screen in a graphical representation. The transducer forms major part if the fish finder. A high-quality transducer will ensure a high-quality fish finder.

The transducer come in diverse types of materials. A plastic transducer is perfect for a causal fisherman however for bigger projects you might need a wooden or a steel transducer.

The display quality

The display of a fish finder forms a very important part of it. It is responsible for displaying all the information that has been received through the sonar waves. The higher the resolution of the display, the more detailed images and graphical representations will be displayed on the screen.

The resolution of the screen will depend on the pixels that it supports. You might want a high-resolution display for more detailed information.


You might be familiar with pixels. These are just small dots that make up the display of your machine. Just like power, pixels are also a very important component of the performance of the fish finder. The more the pixels, the more detailed will be the image be. A detailed image means an image of high resolution and clear display. Billions of pixels join together to form the high-resolution display. The resolution can be defined as 860×860 pixels which basically means 860 pixels in each row.

The fish finders come with small display screens. You can however, look for the highest size screen you can find and what your budget allows. A good screen will be a valuable investment for you as it will save you from spending on a bigger screen fish finder later on when you need to expand your work. Small screen fish finders will not be a bad choice too.

The size of the screen will however determine how clear your image is.


The frequency is a critical part of the fish finder. Only a right frequency fish finder can gather all the information from the under water. Especially in down imaging fishing when the conditions are harsh and everything needs to be accurate, the frequency plays a very important role.

In the market you will find fish finders supporting different values of frequencies. You need to choose the one which best suits your requirements and which will be ideal for the environment in which you are fishing.

Dual frequency fish finders are also readily available in the market. These are a better option as they can collect more information and they have a high accuracy rate.
