In the current scenario, a fish finder is considered as a basic requirement by the anglers for fishing.

So, if you are new to fish finder, you should know certain important facts about these devices such as their working, usage, installation, advantages, best products, etc. This website acts as a guide to the fish finder users, such that it offers useful information and advantages of fish finders.

What Is A Fish Finder?

A fish finder is used to find the fishes lying beneath the water. It makes use of the sonar technology, to achieve fishing effectively. This technology detects the living organisms beneath the water and displays them on the screen. It is an innovative device that is derived from fathometer; the device used for navigation in the water.

As this is a modern era, the traditional fish finding devices are replaced with new models of fish finding equipment. Various advanced features are added with these models so that the devices can be classified according to these models.

The portable fish finders are designed lightweight and they can be used anywhere at any time, whereas the GPS fish finders are used for locating the position of the device and it can also locate the anglers in the safest region.

How Does It Work?

The working of the fish finders should be known to all the users. Even the beginners should be aware of working because it will increase the performance of angling. As the fish finder is a sonar instrument, the working of the device is also based on the sonar technology.

Working

Generally, there are two main components of the fish finder; they are the transducers and the display. The operation of the transmitter and the receiver transducers constitutes the performance and efficiency of the device.

In addition to the transducers, the fish finding devices should be equipped with the accurate display unit. The accurate display unit can display all the fishes and obstacles within the water. With this display, the angler can angle in a safe environment.

The working of various parts of the device is given below.

Transducers

The transducer is a device that converts one form of energy signal into another form. In fish finder, the transmitting transducer converts the sonar radiation to electric pulse and then it transmits this pulse to the receiver. The receiver can be connected to the transmitter, through wired control or wireless transmission, using Bluetooth.

Transducer

In the receiver, the received signal is converted into a suitable signal that the display can view it on the screen. The transducers are designed in such a way that the transmitted signal is received without any loss in the signal. This makes detection of the fishes easy so that fishing and angling can be performed with higher performance.

Display

The display unit can be of various types. Many traditional and conventional fish finders use black and white display unit that can view the images with the variation in the gray scale. Some advanced devices are designed with the colored display unit.

Display

This display unit views the resources beneath the water with the variation in colors so that even minute changes beneath the water can be viewed within the screen. In addition to this, some devices use mobile phones as the display unit.

Working

The working of the equipment is simple. For better working, first, the angler should read the manual and fix the device in a perfect region referred in the manual. Next, they should switch on the transmitter transducer. After this, power ON the receiver transducer and check whether the transmitter interfaces with the receiver. After interfacing, the display is turned ON and this display views the region beneath the water clearly in the screen.

What Should You Consider When Buying A Fish Finder?

There are various types of fish finders and one should choose the perfect fish finder based on their usage. The important points that should be noted before buying a fish finder are given below.

Cone Angle

Cone angle determines the width of the sonar radiation spread beneath the water. The cone angle is higher at the base and it narrows near the transducer. Narrow cone angle has high sensitivity, but low coverage area and the wider cone angle have low sensitivity, but high coverage area.

So, cone angle should be selected in such a way that it does not affect the coverage area and performance of the device. For high-performance fish finders, the cone angle should be in the range of 9-29 degrees only. Hence, the angler should select devices with perfect cone angle.

Cone and Beam

Beams

The beams of the sonar radiation vary based on the model of the device. The types of beams used within fish finders are a single beam, dual beam, triple beam, and multiple beams. The number of beams increases the efficiency of the device but, the disadvantage of multiple beams is the cost.  So, the beam selection is purely based on the budget of the angler.

Fixed or Portable

The fish finders are designed in two models, the fixed devices are fixed with the boats and then operated whereas, the portable devices can be taken anywhere and it can be used in various boats. The angler should select the correct model before buying the device.

GPS

Mostly, many fish finding devices are designed with GPS. This system locates the users and so, it keeps them in a safe environment. In modern fish finders, chart plotting technology is also installed with GPS and with this, the angler can find the path of their travel.

GPS

Other Factors

There are certainly other factors that should also be considered while buying a fish finder. The frequency of the transmitter should be high. Mostly, fish finders come with the frequency ranges of 50, 192 or 200 KHz. In this high-frequency, devices offer higher detection range. The screen used should be selected with high pixel range and durability.

In addition to this, the high speed of coverage, variable temperature operation, and high distance coverage should also be considered while finding the effectiveness of the device. Follow the above points and select a fish finder with high performance and quality.
