Types of Fish Finders

​There are various types of fish finders, but all are designed to serve the same purpose to make fishing easy and convenient. The leading roles played by fish finders include measuring the depth of the water; give a graphical representation, composition, and the entire structure of the underneath.

Various types achieve the roles in with varying precision depending on their specifications. The fact that there exist different types of fish finders means that you need to decide on which to purchase. You should check on factors such as the size of the screen, its portability, price, the frequency, and screen readability.

Some of the common types of the fish finders are:

Parts of Fish Finders

Fish finders have four main components which are the transducer, a display, a transmitter, and a receiver. The transducer and the display is connected to the transmitter and the receiver.

The transducer acts as the ears of the device while the display is a screen where you can see the presence of fish in the water underneath. The transducer is attached to the body of the fishing boat either in the hull or the motor that lies in water while fishing.

The transducer works using sonar technology which helps in recognition of objects using electronic signals. It, also, shows the size of the objects, which in this case is the fish and their distance which is then relayed to the screen in the form of graphics.

How Fish Finder Works?

​The transducer creates an electronic wave which is then passed through the water by the transmitter. At an instance where the wave gets blocked or interrupted by objects lying in its way, it bounces back to the display unit, giving an impression of the objects under the water.

Any time the sound waves hits an object which in most cases is fish, its size, shape, and depth is accounted for, and a graphical display is sent to the display unit. The accuracy of the size, distance, and shape wholly depend on the strength and frequency of the transmitting device.

The time interval between the time the signal is transmitted and the time it is shown on the screen and is used in estimating the distance of fish from the fishing vessel such as the boat. In freshwater, the speed of water is approximately 1460 m/s while in seawater it is 1500 m/s.

The display unit in the form of a screen is the part that you interact with most of the time and is where information concerning the objects in the water is shown. The images cast on the screen shows what is happening beneath the screen and is left for your interpretation.

Modern fish finders have several frequencies to make a good view possible to be used in different situations. Using a high frequency, a more accurate impression results because a narrow cone-shaped angle results.

In a case where lower rates are used, deeper penetration is possible, but the problem comes in that the long-range lowers its sensitivity.
