Sonar Page
The Sonar page is where your GPSMAP 192C Sounder becomes
a powerful fishfinder/flasher. Fish are displayed as colored arches
or as fish icons. Both fish icons and arches are displayed in three
different sizes. Thermoclines are shown as shades of blue. The area
of strongest sonar return is displayed as solid white (if Whiteline
is active. Typically, the bottom is the primary whiteline. A thin
whiteline indicates a soft bottom and a thick whiteline follows the
contour of the bottom and show any objects of reasonable size.
