I can not seem to get the fish arches working on my humminbird 997 just the icons. Help?

When you select to show the Fish ID Symbols Humminbird shows thicon over the processed sonar (what you would normally see), they do not cover up the sonar reading with the Fish ID Symbol. Turning the Fish ID Symbols off just eliminates the fishy above the arch (if your unit was going to show the fish with an arch). Now to get a perfect arch the angle of the transducer needs to be horizontal and the fish must pass through the beam just right.Most often you will see half arches and straight lines and such. Perfect arches are hard to achieve so learn to recognize the variations of the arch as fish.
