Sonar Page
Sonar Page
The Sonar Page is where your GPSMAP 188/188C/238 Sounder becomes a powerful fi shfi nder/
asher. Fish are displayed as colored arches or as fi sh icons in three different sizes. Thermoclines are
shown as shades of blue. The area of strongest sonar return (or whiteline) is displayed as solid white.
Typically, the bottom will be the primary whiteline. A thin whiteline indicates a soft bottom while a
thick whiteline will follow the contour of the bottom and show any objects of reasonable size. For more
information on understanding sonar and the display, see page 14 and Appendix I.
