Understanding the Humminbird Side Imaging

If you wonder how to read Humminbird Fish Finders, you need to understand the side imaging beam casts tow slim beams. One on each side of the vessel, in a 180-degree beam that lies under it. This thin beam covers an area up to 240 feet on each side of your vessel from left to right of your boat location. You will be able to see the 450 feet sight of the water that you will be fishing which will benefit you in catching fishes. You can clearly see the objects under your boat and their position in relation to your boat.

Furthermore, most of the Humminbird fish finder that has Side Imaging also has the feature of Dual-beam plus Sonar. Likewise, the sonar works in water whose depth is up to 1500 feet. Side imagining is only readable up to 200 feet in depth. You will have to work with the switch fire mode if you want to go beyond that depth.
