All anglers will tell you that fishing is relaxing and thrilling at the same time. However, it can be frustrating if you do not catch anything while everyone else in the vicinity seems to be very successful. Their secret lies in using fish finders. These magical devices scan the water and send back signals to the screen so that you can see what is present. However, traditional fish finders cannot scour crevices, nooks, and structures in the water. These structures are renowned for holding fish and are often considered the best places to fish.
That is where a side imaging fish finder comes into play. With this type of fish finder, you will be able to identify all structures and objects in water as they scan 180 degrees either side of the boat or watercraft and ensure you find the best spots to cast your bait. Also, a majority of side imaging fish finders tend to penetrate deep into the water and cover larger areas so you enjoy better quality images and more detailed readings.
Side imaging sonars are able to differentiate between fish and underwater structures as they ensure you get a clear picture on the device’s screen. So, if there is a fallen branch in the lake or pond, the side imaging sonar will be able to scan it properly and this image will be displayed on the screen. You will not mistake it for a fish and hence, you will not try and fish in that area.
It is advisable to note that the best side imaging fish finders are extremely accurate. This accuracy comes from the advanced technologies that are incorporated into the device.
With so many different types of side imaging fish finders, it can be tough to choose one that is right for you. Thankfully, you can check the reviews of our 10 best side imaging fish finders and then decide.

Buying Guide for the Best Side Imaging Fish Finders in 2021
There is a reason that anglers love side imaging technology in their fish finders. Fishing may be fun and relaxing as long as you know where to find the fish. The best fish finders do just that. They help you find a large cache of fish in lakes, ponds, and seas. However, the key is to ensure you have the best fish finder; otherwise, there is no way that you will return from a successful fishing trip.
The best fish finders come with side imaging technology. This technology has the ability to detect more fish compared to traditional sonar. You will notice that the standard sonar will not be able to detect the fish that side imaging sonar can. Also, side imaging sonar tends to scan the water on either side of the boat and this allows you to see where the fish are located in relation to the boat.
So, if you are looking to buy the best side imaging fish finder, here are the features that you should be looking at:
Your Vessel:
The best side imaging fish finders usually come with mounts and using those mounts, you can mount them on the dash or hull. If you use a kayak, it is best to opt for a fish finder that is portable and battery-operated. Also, the smaller the fish finder, the easier it will be to accommodate it on the kayak.
For boats, you can mount the fish finder on the dash, transom or hull. If the fish finder can be mounted on the transom, make sure it has the right hardware and mounts to ensure that it stays safe after mounting.
The speed of the boat needs to be in harmony with the chart speed as if your boat is faster than the chart speed, it will cause distortion and inaccurate readings.
Ease of Use and Setup:
Since these devices have a number of applications, it is best to find a side imaging fish finder that has a user-friendly interface and is intuitive. That way, you will not have to struggle to learn the technologies and utilize them to your benefit.
Also, the setup should be simple, quick, and convenient. The device should come with the necessary brackets and hardware so that you can install it. Having an instruction manual that is easy to follow will help you and ensure you can get the fish finder up and running within no time.
Transducer:
This is the most important part of your fish finder as it sends back signals from the sonar to the display. Make sure that the transducer has different frequencies for side-scanning, down scanning, and CHIRP sonar so that you get a 360-degree view of the water and what lies under your boat. Also, make sure that the cord of the transducer is strong as a broken cord is a common problem among anglers.
Frequency Range:
Most fish finders transmit signals at 15 kHz to 200 kHz. However, all fish finders do not come with this wide range of frequencies. So, if you are looking for the best side imaging fish finder, find out the frequencies that the device has and then educate yourself so that you know which frequency to use when. This will ensure you enjoy a superior performance from the device.
Lower frequencies are ideal for deep water and wide cone. On the other hand, if you want to know what is happening under your boat, opt for high frequency. Be prepared as the images and readings from higher frequencies will not be as clear as those from lower frequencies.
Display Screen:
The screen resolution is important as you will want the highest possible resolution so that you can view the images clearly and precisely. Remember, the side imaging will be of no consequence if you cannot identify what you are seeing on the screen. Also, ensure that you can read and see the screen in bright sunshine without any problem.
It is advisable to opt for a colored screen as you will be able to identify fish arches, structures, and vegetation with ease. When you can see things clearly, you will be able to identify them and not mistake them for fish. Also, a colored screen does not make viewing monotonous.
Durability:
Your fish finder can get wet while you are fishing and hence, make sure that it comes with a high IPX rating. The higher the rating, the more resilient it will be to water. The fish finder also should be sturdy so that it can take rough use without showing visible signs of wear and tear.
Fish finders are expensive and the last thing you want to do is break the device on the very first use. So, find a durable device that can take a beating is what you should be looking for. Such a device will give you years of service without any problem.
Portability:
Portability is not an issue if you intend to mount the fish finder. However, if you want to carry it along with you on the trip or use it on a different boat, it is best to get a smaller side imaging fish finder that is easy to carry.
Mounting Style:
You can mount side imaging fish finders in different ways. A transom-mounted finder means that the transducer is mounted on the flat portion of the stern, where the two parts come together. Transom mounting is the most common type. However, you can also mount the transducer on the hull.
You may find that the best side imaging fish finders come with built-in mounts and this makes it convenient to mount it on the trolling motor while fishing or when the anchor is dropped. When you opt for this type of mounting, it enables the transducer to scan the water better and get more information.
Price:
This is perhaps one of the most important factors as many people use price as the sole criterion of choosing side imaging fish finders. However, it is important to realize that the best side imaging fish finders do cost a lot and at the same time, it is possible to get a good side imaging fish finder that is not exorbitantly priced. That is why you need to look at the features to justify the cost.
Warranty:
Most devices come with a one-year warranty for manufacturing defects. It is rare to find a fish finder with any other type of warranty. Lowrance is one brand that offers an upgrade program for five years. Otherwise, other brands do not offer anything other than the warranty.
Our Verdict
These are the 10 best side imaging fish finders. Each has its pros and cons and that is why you should read the reviews carefully to ensure you find the perfect side imaging fish finder for yourself.
According to us, out of these 10, the best is Helix 7 Fish Finder by Humminbird.

The CHIRP sonar allows you to pinpoint fish arches and you can use the preloaded maps of lakes and coastal areas to identify marinas, buoys, markers, and other features.
