Thread: Sonar Quiz #19

In the previous quiz we learned that the "leading" and "trailing" ends of a full arch (from a properly adjusted xducer) ...are indications that the target (fish) was at a greater "Range" from the xducer than when the target (fish) was in the center of the sonar cone...

In the depiction below...explain why the arch is painted thicker at the "center" than it is painted at the "leading" and "trailing" ends...
