The Sonar Page is where your GPSMAP 292/298 becomes a 

powerful fishfinder/flasher. To view the Sonar Page, press PAGE 

repeatedly until it shows. Fish are shown as colored arches or as 

fish icons. Thermoclines are shown as shades of blue. The area of 

strongest sonar return shows 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. For more 

information on understanding sonar and the screen, see
