The small little oval of course, is to show that you've selected it. Next out is the frontal lobe of the active sonar, it it uses it, for about what? almost 180 degrees of frontal coverage?? The other lines for about 120 degrees might be that. Next out would be passie hydrophone of about 270 degrees of coverage. What I don't see is a visual circle or oval, unless you're zoomed-in too close, and they're loading the guns as I type... ??
- oop, yeah! There's a piece of the curve of it way behind your boat! Run away! Run away!!! Unless you're submerged, of course...
