Technology has taken over every aspect of modern life and angling makes no exception. Nowadays, you can locate seafood underwater with the help of a fish finder (sounder). This technology was first used in the 90s and it has witnessed constant evolution ever since. Should you really invest in one? Yes, you should. A device like this determines the exact location of fish, assumes its number and size, determines depth, and understands wave speed and water temperature. As you can see, a sounder is a very clever device.

When choosing a product to make your fishing a little bit easier, see what Fish Finder Guy has to say. Using a fish finder to locate bait is not brain surgery, but it does take some time to get used to it. You just see a bunch of dots and lines when you turn the machine on. You do not see the bait. If you do not know how to read the gear’s screen, continue reading.

Types of fish finder displays

There are 4 main types of fish finder displays, so let us take a closer look at them.

  1. Waters are divided into different depth zones. Not all fish reside at the same depth level. Some sounders show the depths where the bait lives, clearly displaying the underwater conditions. you enjoy underwater viewing advantage.
  2. Location. Thanks to advanced technology, you can see where the seafood is with the fish finder. The gear shows images from all around the boat.
  3. Underwater temperature is not the same as outer temperature, changing every hour or so. If you are not angling just for the sake of it, you will appreciate a sounder that is able to illustrate temperature modifications.
  4. The transition of temperature are displayed in a numerical way.

What you have to remember is that the reading on a down imaging screen is displayed from the right to the left. You will always see the latest readings on the right side of the screen. On the top right, the depth of the water is illustrated, while the readings on the bottom indicate temperature and speed. The screen can become tricky to read if your boat is not moving.

If you have a basic level fish finder, one that comes in many shades of grey, look on the upper left side of the screen. You will notice 2 couples of numbers there. These numbers stand for the depth of the water and the temperature of the layer of water under your boat.

Fishing devices with side imaging, that work from top to bottom, are not complicated to read. The object at the top is the boat, while the bottom objects are the bait. The display is very, very clear.

In some cases, you might see colored readings. The green readings refer to the position of the structure beneath the water. If a high-density fish passes underneath your boat, you will see red and orange hues. The color depends on the gear, though.
