How to Read Fish Finder Sonar Technologies

We teamed up with Jeff "Kolo" Kolodzinski of Humminbird to create this detailed sonar video tutorial. The featured product is Humminbird's original HELIX 12 (pre-MEGA Imaging), but the concepts will help you regardless of fish finder manufacturer make and model. Kolo breaks down how to read and interpret what side imaging, down imaging, and two-dimensional (2D) sonar are showing you, and how they can improve your fishing. We filmed real-time drone and underwater video of screen readouts to show you what rocks, weeds, fish, and bottom hardness changes look like on the screen, from the air, and below the water.
