How to read your fish finder’s screen

A fish finder is a useful device to have for divers, anglers, fisherman and all those people out there who love fishing. The popularity of the fish finder is increasing each day and many consider it as a very useful fishing gear to own. Before you go out to buy a fish finder, it is better to do some research and then invest your money on a product that is useful for you.

Once you are done with choosing your best fish finder and have purchased one, the most complicated process is to figure out how to read your fish finder’s screen. It is very important for you to understand it completely before you go for fishing. Here, we focus on a few tips which help you with reading your fish finder screen.

Before you start figuring out how to read your fishfinder, you need to understand the logic behind how a fish finder works. The transducer or the bottom part of the fish finder that is submerged in the water emits sonar waves. These waves bounce around and finally return to the transducer. The transducer then reads this information and gets details like distance, speed and rate at which the waves have returned. It is the job of the transducer to convert this data into visual data in the form of arches and thick colored lines.

The first step in the learning process is to understand the direction of reading. The sonar reflection is displayed from right to left on your LED screen. The latest reading is displayed on the right side of the screen and the oldest reading is at the extreme left. If your boat is moving, then the right side of the screen displays what is present exactly below the transducer and the left side displays whatever you have passed already. If your boat is stationary or stable, then the image is also quite stable.

The next step is to read the depth of the water and the temperature. These parameters are displayed on the upper left side of your LED screen. The depth is displayed at the top left and the temperature is displayed just below the depth. When your boat is moving, the fish finder will show a green layer; it means beneath the surface, there is a soft bottom. If the screen is showing only red color thick lines, then it means there is a hard surface beneath your current position. If your screen is showing green lines along with red colored lines then it indicates a structure beneath the water and close to the bottom. If your screen is showing arches over this structure, then it means there are lots of fish in this area.

The screen sometimes shows you images of tree like objects. This indicates that beneath the surface there are lots of trees or weeds. If you are seeing tiny dots spread through the purple layer, it indicates small fishes are present. It can also mean that large fishes are near to the area.

Most of the images displayed in your fish finder will be hard for you to identify and understand in the beginning, but once you start using the fishfinder regularly, you can easily comprehend each and every indication or symbol and enjoy your day fishing in water with a lot of catch.
