In recent years, fishing enthusiasts on trophy fishing trips along the Putorana Plateau have been using fish finders. These devices display the presence of fish, holes, depth, and more on a monitor. These various devices allow you to catch a wide variety of large fish. Beginners who have never used such devices before are unlikely to understand how to read the image or the differences between fish finders without assistance.
Variety of echo sounder types.
They come in various modifications and models. Furthermore, the latest technologies allow for the production of more convenient, high-quality devices. Echo sounders come in a variety of types and are divided into the following categories:
Coastal
These devices are designed for shore fishing. They are the most affordable and readily available. These echo sounders show the presence of holes, riffles, and riverbeds. They can also be used to determine the bottom of a body of water. Some devices can even show fish or signal when they approach.
These electronic devices are helpful when exploring new bodies of water. Shore-based echo sounders are very popular. Their disadvantages include a small display and limited detail resolution.
Boat
Fish finders designed for detecting fish from a boat are more popular. Location and scanning are achieved using multiple beams. The device allows for scanning large areas of the bottom. They also display temperature and fish proximity.
The advantage of these devices is that they can scan even from a moving boat. When rafting on the mountain rivers of the Putorana Plateau, the image is clearer and sharper. Fish do not blend into the bottom of the reservoir. Therefore, these devices are often used during route visits.
Universal
Considered one of the coolest electronic devices, fish finders offer a wide range of features. Advantages:
- They produce high-quality detailing and scanning even over long distances.
- 4 beams scan with huge viewing angles.
- The device supports satellite communication with various gadgets (computer, smartphone, etc.).
- Allows use in the dark
Winter
This type of echo sounder scans only the area below the ice hole. Its advantage is its ability to operate at low temperatures. The image from the scanner on winter echo sounders is clearer and more precise.
Using summer-type devices in winter can result in severe interference, resulting in blurry images and poor detail of the water body.
Therefore, their use in cold weather is not recommended.
How to read a drawing.
Sonar most often shows fish as a dot or arc. Some fish finder models even allow you to see bait and can also identify fish. The downside is that the device may signal approaching fish when none are present.
Scanning should be done from different angles, downward and sideways. This will allow for a clearer understanding of the bottom's condition and the presence of fish. The downward angle scans details beneath the boat. The side view shows what's on both sides of the vessel.
To determine the size of a fish, pay attention to the thickness and width of existing arches and dots. You can also use additional sensors. Larger fish show up as thick, full arches. Smaller fish show up as slightly curved or partial arches.
