As a fish begins to enter the cone angle, its signal is weak and is displayed in a “weak” color such
as light blue or green.
As you move directly over the fish, putting it in the center of the cone, the signal gets stronger and
changes to “stronger” colors until it creates a core. The core color is the strongest signal return
from the fish.
As you move past the fish, its signal gets weaker and decreases back to the weakest colors until
the fish leaves the cone angle.
Schools of fish are displayed as “clouds” of color. You can tell how close together the fish are by
the color of the cloud.
