How to Read a Fish Finder

how to read fish finder

You may be able to guess the size of the fish from the arch it shows on your fish finder. Big fish have a thick and curved arch. Small schools of fish show up as dots. The thickness and shape of the arch and the dots indicate the behavior pattern of each fish. Read on to learn how to read a fish finder and how to use it. Then, you’ll have a better chance of catching the prized fish you’re looking for.

Species of fish

One of the things that you should understand when reading the species of fish in your fish finder is that schools tend to bulge and are easy to identify. However, individual fish are often smaller and will move aimlessly. These fish are not as easy to distinguish from each other because they have different shapes. They also tend to swim at a different depth and have a different shape from the others. These differences are important in reading the different species.

If you are new to fishing, the first thing that you should know is the different types of fish you can catch using your fish finder. You can easily spot the larger fish in the finder if you know what to look for. The arch will be the most prominent and thickest if you’re targeting big fish. In a screenshot below, you’ll notice a 7.5-pound northern pike that an angler caught using a Doctorsonar.

Size of fish

When identifying fish, you will often notice the size of the arch if the fish finder is displaying it. Obviously, a larger arch indicates a bigger fish. However, it is important to remember that the fish finder’s arc does not always correspond to the actual size of the fish. It is often easier to estimate the size of the fish by comparing the arch with the size of the fish in the water.

Some fish finders have huge screens. They can even rival the screen size of a laptop computer. To make things more convenient, many of them have additional features that can be customized for your specific needs. One of these is the ability to tell you which type of fish you are targeting. By choosing a fish finder that allows you to choose the best size for your needs, you will be able to catch the right kind of fish, no matter where you’re fishing.

Shape of arch

When reading the shape of an arch on a fish finder, you need to be able to discern the size of the fish. Big fish are typically red while small ones are light green. When it comes to fishing, the general rule of thumb is that a bigger arch means a bigger fish. Often, small fish can be difficult to spot and you may only notice the arch on a large fish when it is too close to the bottom.

Fortunately, there are some tricks to help you read a fish finder. One of these is to learn to correlate the size of a fish with the shape of an arch. This way, you’ll know whether the fish you’re catching is large or small. The arch will not be an exact measurement every time, but it will help you judge the size of your target fish. Learning how to use a fish finder will help you catch more fish.

Sonar beam

If you’re not familiar with the basic terminology of sonar, let’s start with the different ways you can view it. You’ll see both a wide and narrow beam. While the width of the beam is dependent on the frequency, the wider the beam, the closer a fish will be to your boat. A wide beam will show a wide area, and a narrow beam will show a small area.

Most fish finders use sonar technology to identify fish. These devices emit a narrow beam of light and cover only a portion of the bottom. However, you can still read the beam on a fish finder effectively by learning how to interpret the resulting image. Down imaging is the most common type of fish identification feature in fish finders. The Fish-ID feature converts the raw data from the water to an easy-to-read interface so you can identify the species of fish beneath your boat.

Color of arch

While the color of the arch on a fish finder is important, it’s not the only indicator of where to fish. Anglers often use the arch thickness to determine the size of fish in their area. Other factors to consider when choosing a fish finder include the depth of the water, cover, and structure. If you aren’t sure which arch type is right for you, use GPS to determine your location.

The width of the arch is also important to consider when using a fish finder. A wider arch means a larger fish, while a smaller arch means a smaller one. The arch shape also matters. If a fish swims through the entire sonar cone, it will appear as a full arch. If the arch is partially occluded, that means the fish is smaller than the one you are targeting.
