The first benefit of a side imaging fishfinder is that you can see all the fishes alongside your boat. While the column angle on side imaging is often smaller than that of the primary downward beam, it still has sufficient resolution to allow you to observer all the fishes nearby.

The Humminbird Side Imaging fishfinders do include standard downlooking “2D" sonar if that is more to your speed. Simply switch to the “2D" mode and use your fish finder the way you’re used to.
