What are you looking for on a sonar for shrimp is it a cluster of a ball like picture?

When using sonar to find shrimp, you're typically looking for a distinct cluster or concentration of returns that appears as a ball-like shape on the screen. This indicates a dense school of shrimp, often showing up as a more intense echo compared to the surrounding water. Pay attention to the size and shape of these marks, as well as their depth, to effectively locate shrimp in the area.
