sonar cone........
the best analogy is that it's like shining a flashlight in the dark.
if in side-scan mode and the fish is facing the boat then you get much less of a ping then if it's sideways to the boat.
I had one of the first side scanners...
.and i can tell you from experience from a plugger's perspective...
that when you mark
a fish out to the side within casting range....
and you cast just beyond it
and reel the bait right to where you approximate the fish is.... and hook up
it's .... as good a feeling as sight fishing to fins breaking water.
