If you are looking to purchase a fish finder, it is essential to first understand the different types of fish finders available on the market. Here are the 9 different types of fish finders available in the market today:

Different Types of Fish Finders Explained

Now that you know the different types of fish finders available, let’s take a more detailed look at each one.

Side Imaging Fish Finder

Side imaging is a type of fish finder that is used to locate fish in the water around your boat.

Side imaging fish finders work by emitting sound waves from the side of the boat, which then bounces off of objects in the water and return to the fish finder.

The fish finder then interprets these sound waves and displays them on a screen, which allows anglers to see what is in the water around them.

Side imaging fish finders can be extremely helpful for finding fish that are hiding in cover or structure, as well as for locating schools of fish.

Side imaging fish finders are an essential tool for any serious angler and can help you catch more fish.

Down Imaging Fish Finder

A Down Imaging Fish Finder is a special type of fish finder that uses sonar to create a detailed image of the bottom of a body of water.

Down Imaging Fish Finders are becoming increasingly popular among fishermen, as they provide a more accurate view of the underwater environment than traditional fish finders.

In addition to showing the structure of the bottom, Down Imaging Fish Finders can also reveal the presence of fish, struggling baitfish, and other potential obstacles.

As a result, Down Imaging Fish Finders can be an invaluable tool for anyone who loves to fish.

Mega 360 Imaging Fish Finder

Mega 360 Imaging is a new technology in fish finders that allows anglers to see a 360-degree view of the underwater environment.

This gives anglers a much better idea of where fish are, what they’re doing, and how to catch them.

Mega 360 Imaging uses a high-frequency sonar to create a 3D image of the underwater world. This image is then displayed on a screen, giving anglers a real-time view of their surroundings.

It is an invaluable tool for any serious angler, and it’s sure to help you catch more fish!

Live Sonar Fish Finder

Live sonar fish finders are a popular choice among fishermen. Traditionally it’s called LiveScope fish finder. They use sound waves to detect the location of fish and then relay that information back to the fisherman in real-time.

This allows fisherman to adjust their flying tactics and increases their chances of landing a big catch.

Live sonar fish finders come in a variety of shapes and sizes and can be used in both fresh and salt water.

They are an essential piece of equipment for any serious fisherman and can give you the edge you need to come home with a full cooler.

Chartplotter Fish Finder

A Chartplotter is a device that combines a GPS receiver with a display for marine navigation. Chartplotters can be used to plot the position of your boat, as well as to find fishing hot spots, track weather patterns, and more.

Most Chartplotters come with built-in maps, but you can also purchase updates and add-ons to keep your maps current.

Chartplotters can be used in conjunction with fish finders to give you a complete picture of what’s going on beneath the surface.

When choosing a Chartplotter, it’s important to consider the size of the unit, the type of display, and the features that are important to you.

With so many options on the market, there’s sure to be a Chartplotter that’s perfect for your needs.

Portable Fish Finder

Portable fish finders are a relatively new type of castable fish finder that has become extremely popular with anglers in recent years.

As the name suggests, castable fish finders are designed to be cast out into the water, where they sink to the bottom and begin scanning for fish.

Most castable fish finders use sonar technology to detect fish, and they can be extremely effective at locating both small and large fish.

Some of the newer models even come with GPS capabilities, so you can easily mark spots where you’ve had success in the past.

Whether you’re an experienced angler or just getting started, a castable fish finder can be a valuable addition to your tackle box.

2D Sonar Fish Finder

2D sonar fish finders send sound waves down into the water and then interpret the returning echoes to create a profile of what is beneath the boat.

This is the oldest type of sonar technology and is often referred to as traditional sonar.

While 2D sonar doesn’t provide as much resolution as side imaging or down imaging, it does have the advantage of penetrating deeper into the water than either of those other technologies.

This means that it is the main type of sonar used by anglers targeting fish in deep water.

3D Fish Finder

There is no doubt that a 3D fish finder produces some of the most impressive images of any type of fish finder on the market.

By combining data from a side imaging transducer into a 3D image, it becomes much easier to see how the fish relate to structure in the water.

This is in contrast to other fish finders, which generate a 2D image that you then need to interpret to extrapolate 3D information.

While a 3D fish finder does have this advantage, I believe it doesn’t provide you with as much of an advantage as most people think.

Ice Fishing Flasher

Ice fishing flashers are devices that are used by ice anglers to help them locate fish beneath the ice. There are a variety of different types of flashers on the market, and each has its unique features.

However, all flashers work in essentially the same way. They use a transducer to emit sound waves into the water, which reflect off of objects in the water, including fish.

The reflected sound waves are then picked up by the transducer and converted into an image on a screen.

This image allows anglers to see where fish are located so that they can drop their bait in the right spot. Ice fishing flashers are essential equipment for anyone who wants to enjoy success while ice fishing.


CHIRP sonar stands for Compressed High-Intensity Radar Pulse and is an advanced type of sonar technology. It is used by most fish finders on the market today because it is more accurate than traditional sonar.

Traditional sonar uses a single wavelength to send out a pulse of sound and then listen for the echo of that pulse when it bounces off objects in the water.

This process can be inaccurate because the echo can be distorted by things like temperature changes, turbulence, and reflections from the surface of the water.

CHIRP sonar uses several wavelengths at the same time which helps to eliminate these inaccuracies. This means that it can give you a more accurate picture of what is below the water’s surface.

CHIRP sonar is currently the industry standard for most 2D, side imaging, and down imaging fish finders.

What Type of Fish Finder Should You Choose?

How to Choose the right fish finder

The type of fish finder you choose should be based on your specific needs and preferences. However, there are a few factors that you should consider when making your decision.

The first factor to consider is the type of fishing you plan on doing. If you’re an angler who likes to fish in deep water, then a CHIRP sonar fish finder is the best option for you.

If you’re more interested in seeing what’s happening beneath the surface of the water, then a side imaging or down imaging fish finder would be a better choice.

The second factor to consider when choosing a fish finder is your budget. There are a variety of different fish finders on the market, and they range in price from around $100 to $1,000 or more.

So, before you make your decision, be sure to set a budget and stick to it.

If you choose a side imaging or down imaging fish finder, it will cost you more than a traditional 2D fish finder.

However, the investment will be worth it if you’re serious about fishing. This type of fish finder will give you a much better idea of what’s happening beneath the surface of the water and help you to catch more fish.

Finally, consider the size and weight of the fish finder. If you plan on transporting your fish finder to different fishing spots, then you’ll want to choose a model that is lightweight and easy to carry.

However, if portability is not a concern, then you can choose a larger and more feature-rich fish finder.

No matter what type of fish finder you choose, be sure to do your research and read online reviews before making your purchase.

This will help you to find the best fish finder for your needs and ensure that you’re getting a quality product.

Fish Finder vs Depth Finder

A fish finder is a tool that uses sonar to detect fish underwater. It works by sending out sound waves and then measuring the time it takes for the waves to bounce back.

The Findings are then displayed on a screen, which shows the shape and depth of the object.

A depth finder, on the other hand, simply measures the depth of the water. It uses sonar to detect how deep the water is and then displays this information on a screen.

While a depth finder can be used to find fish, it is not as effective as a fish finder. This is because a depth finder only measures the depth of the water, while a fish finder also detects the shape of objects. As a result, a fish finder is better at finding fish than a depth finder.
