What is fishing finder?

Fishfinder is a simple advancement of technology in the form of a device that helps to locate fish in the water bodies. The principle behind their working is the technology of SONAR which stands for Sound Navigation and Ranging system. It is surely a well-made product that serves people both for recreational as well as professional fishing purposes. What basically a fish finder does is simply locate the position of the fish and display it on a digital screen. The fish finder technology has seen huge advancement in its technology since its advent in the 20th century. Today’s technology used in the fish finders has advanced GPS ( global positioning system) tracking radars and compasses that are electronically designed which enhances the reliability of the fisherman on these tools. It consists of a transmitter that gives out electrical impulses. These electrical impulses are then converted into sound waves using a transducer and are sent back to the water. The fish finder then reads these incoming wave signals from the water body and display digital reading on the screen which helps to locate the position of fishes. There are different types of waves that help to distinguish whether the incoming waves are bouncing back from the fishes or not. The waves that are reflected back from stones and rocks are different as compared to the waves that are reflected back from the coral reefs. So similarly the waves reflected back from fishes will be different and hence the fish finder can easily distinguish between these and let the fisherman know the exact position and location of the fishes. After the waves are received by the fish finder, the display screen activates certain symbols and displays them on the screen which helps the user know the presence, location, and position of the fishes in the water body. The display of the different components is unique and does not create any confusion or ambiguity to the person monitoring the digital screen.

Buyer’s guide

Let’s have a deep dive into some of the key aspects of a fish finder before you decide to buy your own :

Types of fish finders:

There are mainly three types of fish finders you will come across. These are the standalone fishfinder, combo fish finder, and network fish finder. Let’s see what each of them has in store for us.

-> Standalone Fish Finder: These are the type of fish finders that are designed to perform a specific task at hand only. These fish finders are cheap and easily affordable and serve the only purpose of locating what is beneath the surface of the water. They offer maximum performance at minimum price parameter. These are for those who are on a budget and use a small boat to fish around in the nearby lakes or islands.

-> Combination Fish Finder also known as chart plotter These are a type of fish finders that perform a combination of functions and also comprise a chart plotter. They comprise GPS sensors and provides GPS functionality for locating the exact position of the fishes in the water body. These are basically for those who fall under the mid-size boat owners and it makes a lot of sense for them to use this category of a fish finder. The GPS helps the fisherman to navigate to the exact location where the fishes are present in large number by displaying their position on the digital screen. They even comprise of transducers that act as sound modules and interact with the sound waves coming back after reflecting from the fishes nearby or at far off places.


-> Network Fish Finder: These are basically a type of fully-networked systems that offer a plethora of potential functionalities. These all functionalities are viewable using the variety of multi-purpose displays available in the fish finder. They are capable of supporting a wide range of data sources which include radar, GPS charts that fall under raster and vector categories, have video capabilities, and also include SiriusXM satellite radio. They can be even controlled and monitored by your smartphones as well and overall act as black boxes of data of various kinds. These types of fish finders are perfect for both medium-sized as well as large-sized boats.

Type of screen of the fish finder:

Before you make that decision of buying a fish finder for your boat and spend that money, it is very important to know the type of screen that is attached to your fishfinder. There are three important parameters that you need to consider before going for the best screen type that suits your requirements. Those are :

  How should you choose the best screen type for your fishfinder? 


-> Color: This means whether your screen is colored or black and white. If you are not operating a very large-sized boat and just want to use it for recreational fishing, then you can perfectly go with the black and white option. For all other needs, the colored screen option will be the best choice.

-> Pixels/aspect ratio/ resolution: The other important aspect that comes under this segment is the number of pixels that the screen possesses. The number of pixels means better screen while less number of pixels means the quality is much lower. The number of pixels means the aspect ratio of the screen will be greater and the overall resolution will be higher. On the other hand, if a screen has fewer pixels, it usually has a low aspect ratio and low resolution.


-> Size: Before buying the fish finder you should decide what screen size you are comfortable with. Usually, it is suggested that for those who want to go fishing as a recreational activity, a fish finder with the small screen will do the job perfectly. For those who want to do professional fishing, a fish finder with a large screen would be the best option.

Wattage :

The power a fish finder knew as wattage generally is expressed in terms of watts RMS also known as the root mean squared. A fish finder is said to have more power if it can allow you to locate far off areas with high fish density quite easily and display you the exact parameters on screen. Also, tell how much depth it allows you to locate objects also determine the power of a fish finder. This is also related to wattage as well. More the wattage more will be the power.

What is the transducer’s frequency?

There is a huge variety of fish finders in the market that operates on different levels of frequency. Some of them have single-frequency transducers while others have dual frequency transducers. Some of them have multiple frequency transducers while others have a broadband CHIRP system within them. The frequency of a transducer is directly proportional to the details results that you get on the screen. More is the frequency of the transducer, more detailed resolution and details you will get on your screen. This also accounts for very least background noise on the screen. They even give the best results from a fast-moving boat as well. On the other hand, a transducer with low frequency does not possess these qualities and hence do not give better output. But there is a contradiction to this aspect. The low-frequency transducers deal with waves that have the tendency to penetrate much more deeper as compared to high-frequency transducers. Fishfinders with high-frequency transducers are the best choice for shallow waters while those with low-frequency transducers are perfect for deep waters

What is a broadband fishfinder or CHIRP fishfinder?

The acronym stands for Compressed High-Intensity Radar Pulse fish finder which has a little bit different mechanism. Instead of using single or dual frequencies they produce waves that operate in a certain frequency range instead of operating at a certain discrete value. In comparison to conventional fish finders, they transmit a comparatively less peak power

but have a long duration of frequency modulation in their pulses. These types of transducers have the capability to achieve extremely high-quality resolution and also provide a great lot of help in distinguishing objects underwater distinctively. They work perfectly for depths of 10000 feet and more. They have the potential to transmit waves on both high as well as low frequency. When they work on the lower frequency, they get deeper penetration into objects and greater depths and consume less amount of power. On the other hand, when they work on a higher frequency signal, they usually generate less amount of noise. Higher frequency signal results in finer details being produced at the screen even in mid-water depths.

Some high-frequency transducers offer the capability to provide a complete 360-degree analysis for the availability of fishes.

Let’s have a quick look at some of the essential characteristics of different types of transducers:

> High-frequency transducers:

  1. They usually have shorter wavelengths
  2. The number of wave cycles per second is more.
  3. They are more detail-oriented.
  4. Possess average depth capacity.
  5. They provide a much more comprehensive image of the bottom of the water body.   

-> Low-frequency transducers:

  1. They usually have longer wavelengths.
  2. The number of wave cycles per second is less.
  3. They are less detail-oriented.
  4. Possess the ability to penetrate to greater depths.
  5. They provide a less comprehensive and detailed image of the bottom of the water body.
  6. They make use of wide beams.


  1. Price :

The cost factor is yet another important aspect to be considered. Certain fish finders are expensive but worth the price. Others are cheap and affordable but might not be worth the price. The most important thing to consider is to figure out your needs and requirements and then select one that fits your budget. So don’t rush into buying one until and unless you are clear with everything and have researched all the aspects.


The purpose of technology is to simplify our lives and give us the real benefit of convenience. Fishfinder definitely eases up our lives by giving us the leading edge of technology to our maximum advantage. Not only it finds its use for recreational purposes but also at the professional front. The above fish finders are dominating the market with their technological edge and each one of them fits the various needs of its users. There is a whole lot variety available in these above options and you can choose yours depending upon your needs. A lot of other factors also play an equally important role in selecting the best fish finder like price, affordability, accessibility, durability, quality, and versatility. Choosing the right one must not be a difficult task because all you need is a little bit of awareness and knowledge of necessary aspects. So it’s time to make the best use of available technology no matter which segment you are into, be it recreational fishing or professional fishing. All you need to do is careful research and make yourself aware of these things and you are good to go. Happy fishing!
