Sounder for Fishing From the Shore

The use of traditional stationary echo sounders has long been a practice. But here's what to do if there is no boat or boat forbidden. For example, during the spawning period or on a commercial water body, the use of boats is prohibited. In this situation, you can use the sounder for fishing from the shore in order to quickly find out the bottom condition and detect the fish.

We must understand that the possibilities for such an echo sounder are still less than for the classical sonar. But these possibilities are enough to learn a lot about the underwater situation, the presence of fish, the state of the soil at the bottom and the bottom relief.

Sounder for Fishing From the Shore

Many methods of fishing, primarily associated with fishing for peaceful fish, involve careful exploration of the fishing area. This is feeder fishing and carp fishing. To scout the bottom using a marker float, it takes a long time.

And this intelligence, although it allows you to more or less accurately determine the depth, but to establish what really is at the bottom, can only approximately. And in order to determine this, you need a lot of experience and a fairly sensitive marker rod.

And it is certainly impossible to determine whether there is a fish in this place or not. Fisherman can only assume, following his own logic, that there is a fish on this site. But with full confidence he cannot know this. But echo sounders for fishing from the shore are able to give out more detailed information, at least, about the relief of the bottom and the state of the bottom layer.

In addition, the onshore sounder will show the fish that is on a particular site. Naturally, he will not give information about what kind of fish there is. Even the best sounder cannot distinguish, for example, pike perch from carp or bream.

As for the bottom soil, it is possible to determine the density of the bottom using the marker load. Sensations that are transmitted on the rod, quite accurately can give information about the day. You can know for sure whether it is a firm bottom or soft. But in order to properly read the bottom, you need a long practice.

With the echo sounder for fishing from the shore, the state of the bottom, or rather its density, can be determined by the color of the bottom line and by its saturation. Here, too, some skills are needed to decipher the readings of the echo sounder. But it is much easier to master them than to master skills based on tactile sensations.

There is, however, one point that limits the possibility of exploration. This is, first of all, the range of the transmitter that is located in the sounder unit. Really it's about 40 meters. And then there are large signal losses and interference.

But even if the signal were transmitted for a greater distance, the question would still arise: how to throw the sensor of the shore echo sounder at this distance. The shape of the sensor is not aerodynamic, so you can count on casting with a range of 60-80 meters. This, no matter what technique of casting the fisherman did not possess, with this form of sensor and with such air resistance, it is simply impossible.

However, there is another option, when the echo sounder for fishing from the shore is used in conjunction with a radio-controlled boat for fishing. Then the distance of the reconnaissance zone increases significantly. But then you need to amplify the signal that comes from the sensor.

For these purposes, an additional amplifying antenna is used on shore-based echo sounders. In this case, the signal strength is approximately doubled. But not all models of echo sounders for shore fishing have antennas in their set that increase the range of the device.

What is the sounder for coastal fishing

Echo sounders for fishing from the shore work on the same principles as the echo sounders, which are installed on a boat or boat. Only in the case of a shore-borne sounder, the signal from the sensor to the main unit is transmitted via a radio signal.

The echo sounder itself is placed in a sealed enclosure, inside which there is another transmitter. The transmitter will send signals to the receiver, which is installed in the head unit of the echo sounder. Each of the units has its own autonomous power supply.

The sealed sensor has a positive buoyancy, which allows it to stay on the surface of the water. In this case, the floating block is arranged and balanced in such a way that the beam is directed towards the bottom. The conditional vertical axis of the sensor will be perpendicular to the surface of the water. If the direction is displaced, a large error may result.

Depending on the model, the echo sounder may have one or two beams. The most common configuration of a sensor with one beam, but with a large angle of measurement. The viewing angle can vary from 45 to 90 degrees (in different models in different ways).

It may seem that the larger the angle of view of the sensor, the better. In fact, this is far from the case. When the beam is scattered a lot, the scan results are reduced.

This can be compared to a conventional flashlight with an adjustable beam. If the ray is scattered, then the light intensity is worse. If the beam is narrow, then the illumination in a small area is excellent.

How to use the shore-based depth sounder

On the body of the sensor unit there is a fastener to which the cord or rod of the rod is fastened. After that, the sensor goes into the water. After the sensor is in the water, an image appears on the display screen, which shows the depth, the bottom relief, the water temperature, the fish, the depth at which the fish is located.

But at the first moment, while the sensor on the water is still, the bottom will look like a flat line. In a stationary position, echo sounders for fishing from the shore are not able to show changes in the terrain.

In order for the normal reflection of the relief to begin, the sensor needs to be set in motion by rotating the coil handle. The sensor is gradually pulled to the shore and the screen shows how much the depth and topography of the bottom varies, or, for example, the temperature changes. And this may well be if the water is unevenly warmed up.

After the first reconnaissance cast is made, and the picture is not quite clear, you can make a few more casts to find out the relief of the bottom somewhere else. At the same time, casting follows a fan. But one cast may well suffice to determine the picture of the underwater world.
