Types of Fish Finders

For a better understanding of this device, we will divide it into categories based on their distinctive functions, and the features they carry.

  • Standalone Fish Finders

  • GPS Combo Fish Finders

  • Networked Fish Finders

These types come with unique features that make fishing easier. It has bells, whistles, GPS, video display, SiriusXM radio, which is all data-friendly.

CHIRP (Broadband)

Clear images of happening underwater are the reason you are getting a fish finder in the first place. This unit delivers up to 50 times pulse energy, resulting in greater ping power. With the purse power, you get the best images with every detail needed.

Portable Fish Finders

Not all have the pace to keep the giant and huge fish finders. There are times when all you need is a handy fish finder, especially while on vacation. They often come in a clear display unit, transducers, and mounting parts. And for easy of carrying, they often delivered in pouch or case.

Have you heard of castable? That’s the most recent version of portable fish finders. They can float on water, and your mobile device controls their activities with the help of Wi-Fi or Bluetooth.

Ice Fish Finders

These units of fish finders are often referred to as flashers, and this is because they produce only a graphical representation of happenings under the water. Some may show real-time event though, based on the design they feature. 

Working Process of Fish Finder

Having considered the available types, let us examine the working pattern of the fish finder. The images delivered by these devices are in three forms. They vary in their precision and function. The device makes use of the sonar system in creating the image they deliver. The sonar type influences their results. They have different advantages and disadvantages, making each one unique in its field.

Standard Sonar

Standard sonar follows a simple operation process. Beams are sent through a cone of sonar into the water. The resulting sound will help have a clear sense of what is happening under the water. These standard sonars used will you see the arc of where fish are hiding.

The accuracy of standard sonar can be questioned though, although they have improved in function and design over the years, yet they still carry rough sonar type. Their ability to accurately show the depth of the water is called to question, but when it comes to finding fish inside water, they deliver.

Since the data displayed on your screen are not that detailed, understanding the working process might be a little bit tough. But immediately you understand the working process; you will come to agree that it is a great tool.

Down Imaging

This type of fish finder features a more unique and complicated sonar type. The names given to this classy system are numerous. The brand you are looking for is the deciding factor of the name.

One good thing about this imaging system is that it delivers a close to real image of happenings underwater. Unlike the sonar type that shows where the sound is bouncing back from, this one will help you get a clearer and better image.

The uniqueness is guaranteed, and it is an expensive option with quality results. At least you’ll have a clearer picture of happenings under the water. If you are looking at the price, it might be a little bit discouraging since it is a very expensive option.

Understanding the working process is another tough task when using this technology. Fish finders featuring a more detailed and precise sonar system will have better sonar set up which can toggle between. A unique and nice system to explore!

Side Imaging

This type is very different from the two mentioned above. The working process often involves sending beams out to the side. This system restricts you to the left as you can’t see what’s happening on the right, below, or around you. It is often used when exploring or searching for structures around your kayak or boat. The sonar is restricted to a certain radius but produces clear images.

In most cases, side imaging is sold separately, but the technology used is often mixed with other types. On its own, it can work perfectly, but a better result is guaranteed when mixed with the other two technologies the result is more unique. In comparison to the other technology, it is more expensive and can be very hard to install due to the structuring of the sensor. This may not always be valid.

Fish Finders Reading Techniques

The following techniques will make reading the results delivered by fish finder easier for you:

Depth of water

The depth is displayed either in meters or feet on your fish finder. The accuracy will be determined by the model you are using. Transducer components often come with a depth sensor. With depth, you can clearly know the types of fish in the water you’re fishing on.

Speed sensor

Your fish finders need a speedometer. The speed sensor is the worthy speedometer. The performance of your fish finder will be influenced by speed. For some products, there are limitations to their speed, at a specific speed; they stop working due to the emission of sonar waves. Trying your fish finders at different speeds will help you get the exact quality of your device.

Reading the Display

  • Reading of information on your fish finders is from the right to the left side.
  • Recent images are shown on the far-right side of your display screen
  • Release of stronger echo emission is signaled by darker colors
  • The hard structure under the boat is signaled by thick lines.
  • There are some models of fish finders that deliver their data in raw format, while some converts these data into fish icons with the aid of Fish-ID technology. 
  • Only newer models feature this technology.

Sonar Waves are displayed

Every fishing session you complete with your fish finder must include a detailed working process. This will improve your fishing experience when next you are fishing. You do well to note the depth of the water you found clusters of fish.

Chart plotter

Just to ensure you know your present location and your destination, chart plotter was developed. It helps you have a clearer picture of the water, its depth, and the structural makeup of the underwater.

You won’t miss the best fishing spot as you can easily plot out the path or course you will be taking. If there are structures that could endanger your trip, chart plotter helps you avoid them.

Split-screen will help you find fish and plot charts simultaneously. If you go for a combo model, you can then use these tools together. With chart plotting, you can return to the recorded area, and document the GPS coordinates.


What would you do if you find yourself in shallow water? At first, you might feel like all hope is lost. One of the reasonable and viable options is to adopt the zoom component and employ it in peering into the water. This could reach up to 10ft. of water.

The primary aim is to help you understand the structure of the underwater contour vividly in that specific area. As a result, you won’t be oblivious to the type of Fish that could be found in that area. However, an exception of its ability is that it won’t function well in an Ocean body with tremendous depth. 

Besides, there are some types of water where a high-frequency won’t be advisable to be used. Most people have experienced that using it on the water that is densely filled with algae is not productive. You will experience a false reading. And this incorrect reading will lower real value which will, in turn, bore you and lead to unhappy results.
