Things to Consider When Buying the Best Fish Finders

You can choose the best ones by knowing their features and all the benefits they can offer you. However, there are tons of side-imaging fishfinder options available on the market. So remember to choose the best one that would cater to your needs. 

Here are some key factors to consider.


One of the key factors you should consider before buying one is how much battery life your side imaging fishfinder has. When power is low, it won’t work well, and it will be more difficult to locate your prey. 

You can buy a cheap one that has low power and only lasts a few hours. Alternatively, you can buy an expensive one that has high power and lasts up to 2 hours.


Several side imaging fish finders are available, including single-channel depth, multiple-channel multibeam sonar, and multi-beam directional sonar. The image produced by each type varies based on its design and computerized algorithms.


Install your side imaging transducer in a location that is unobstructed from all sides. In addition, your transducer should be connected to your boat’s electrical system so it functions optimally. Poor transducer placement can cause the image to look distorted. 

Screen Resolution

Fishfinder screen resolution, also known as fishfinder view, is the number of pixels the camera lens can capture. The higher this number, the more useful it is for fishing. 

Frequently Asked Questions

Working with the top-side imaging fish finder can be challenging, especially for beginner anglers. For this reason, we have put together some of the most frequently asked questions about this device.

Can You See Fish on Side Imaging?

Yes, it uses side imaging to detect more fish in the water column. It works by using an optical sensor on the front of the unit to convert the light bouncing off the water into electrical signals.
It then looks at one of the hundreds of camera designs, determining what is best suited for detection.

Which is better, Side Imaging or Down Imaging? 

When it comes to your fishing needs, the choice of sonar type will come down to what application you need a fishfinder for. Side imaging is best for shallow water, while down imaging is for deep waters. 

Final Thoughts

Most fish finders come with the latest sonar technologies and are easy to use. They are also convenient because they are lightweight and compact. Thus, having one can help an angler locate fishes that are hard to find. So having the top-side imaging fish finders is a must! 

Nevertheless, we hope that this article helped you in finding what you need.
