Sonar Signal Interpretation

When you monitor your flasher screen for signs of fish, there are three signal band characteristics to watch for: movement, color and thickness.

Signal band movement

In a stationary setting like ice fishing, the bottom, structure and cover will show on the flasher screen as stationary bands of color. Signals between the surface and the bottom that come and go or move up and down (even slightly) will be fish that have appeared inside the sonar signal cone.

Signal band color

The color of the signal bands correspond to both fish size and their posi- tion in the sonar signal cone. Black and blue signals tend to be smaller fish, or fish that are at the outside edge of the sonar cone. These smaller or more distant fish return weaker echoes.

Red signals are much larger fish, or fish that are in the center of the sonar cone, almost directly below the transducer. They return the strongest echoes.

Signals that are yellow and some other color result from mid-sized fish that are in a transition zone between the center and outer edges of the sonar cone. They represent medium-strong echoes.

As a fish moves through part of the signal cone, the signal may change from black to blue to green or yellow then back again. The signals may appear to move up slightly and then back down, even if the fish doesn't actually change depth. This is caused by the relative distance from the transducer to the fish as it passes by the transducer.
