The video shows a close-up of a Garmin fish finder screen. The screen displays a graph with peaks and valleys in different colors, indicating the presence of fish underwater. The colors range from blue to red, with the red indicating the most intense activity. The screen also has a scale on the left side, with numbers ranging from 0 to 80, and a compass on the right side. The fish finder is mounted on a boat, and the water is visible in the background.
