What is a Side Imaging Fish Finder?

A side imaging fish finder is a sonar device, designed to make your fishing trip more successful and productive. Thanks to the improved sonar technology and the special transducer, this device will capture detailed images of underwater structures to help you navigate water bodies and locate more fish – especially in shallower water. This makes it really useful when inshore kayak fishing.

The distance covered by the fish finder is affected by the potency of the device and its power. These devices aren’t affected by mud, light, or other factors, and project the images on easy to read screens.

The sonar beams produced by the fish finder travel to the sides of the boat or kayak, compared to down imaging fish finders that scan the water right under your boat.

How to Choose the Best Side Imaging Fish Finder?

There are lots of good side imaging fish finders on the market, so finding the most suitable one can be a little challenging. Here are a few things to think about before buying your device.


The device’s overall size can be a significant factor, depending on where you wish to install it. Some models are as small as smartphones, so they can be successfully used on a kayak or a canoe. Other bigger models are more suitable for bigger boats.


Bigger screens show more details, so they will be more suitable for avid anglers, and those who wish to navigate deeper water. You need to make sure that the screen is easy to use in all light conditions, so picking a backlit display can be a good option.

You need to make sure that the screen has a decent resolution to show the details of the fish and other structures under the surface of the water. High-resolution screens filter clutter to help you locate fish more successfully. Touchscreens are also available and are easy to use.


This refers to how deep the images can be delivered to the fish finder’s screen. If you’re trout fishing in a stream or a lake, the range of 150 feet might be enough. You need to make sure that the device is designed to draw clear images at deeper water if you’re fishing in saltwater.


Most fish finders come with built-in maps that allow you to navigate the most famous water bodies. However, in most cases, you will have a USB cable or a microSD card slot to upload more maps. This is a convenient feature, especially if you’re planning to use your fish finder for a long time.


1. What does a Side Imaging Fish Finder Show?

You will be looking at fish, which appear on the screen as dots or clusters. You might see more shadows, which indicate that you can find more fish. The fish finder also shows the details of structures on lake bed.

2. Side Imaging vs. Down Imaging, Which One is Better?

Side imaging is more suitable for shallow water fishing, or when you’re planning to dive for water fishing. Down imaging works for vertical fishing.
