HOW SOUND CAN BE USED TO LOCATE FISH

Sonars are specifically designed to help locate the fish which has many systems that has a basic principle from other sonar systems. The sonar device transmits the sound pulses, which can be measured at the time and can be taken from the echoes to return. After the pulses return, you can easily calculate the distance of the object, which can produce you with accurate results. This sonar powered technology can easily send and receive signals many times per second. This provides for a concrete sound into the beam that can be easily transmitted from the transducer. The unit later, with the help of the echoes, can create a visual display of the underwater with the help of a continuous line—the objects in the water and between the surface to help you see the bottom.

These fish finders generally can detect the presence of the fish just by detecting the air in the swim bladders. The air can be easily conserved in the swim bladder, which can work with the changes in the sound path that can reflect the energy back. The fish finder can reflect the energy and convert the fish images on the screen accurately. The fish finders operate one a high frequency of sounds which is 20-200 kHz which helps you define the target it can allow you even differentiate with the echoes or arches. The lower frequencies can easily penetrate in deep waters which can help him have individual targets. Also, it allows you to put more energy into the pulse, which is sent out by the transducer that increases the probability of getting the signal into the deeper waters.

The images which are formed are on visual display can help with the arches and allows you to move with the movement of boats. The sound is transmitted from the transducer into the concentrated into a beam. The sound passes into the deeper waters which later spreads out and covers a wider area. Later, the transmitted sound can be plotted and make it to the pointed top on a broad base.

Fish which can swim within the cone can reflect the sound. The reflected sound, echoes, and appears on the sonar chart display. If you find a school of fish, you can also differentiate between the shapes and the formations which is caused in the transducer cone. A fish arch forms and it can move with the fish as it moves through the sonar beam and enters the cone. The fish swims through the cone the distance between the transducer and the fish which can mark the way to curve up as the fish continues to move through the beam to the opposite end of the cone which increases the distance. This means that the curve can be downwards when the fish is moving further away from a transducer.
