Full Sonar Chart
This is the default mode used when the unit is turned on for the first
time or when it's reset to the factory defaults.
The bottom signal scrolls across the screen from right to left. Depth
scales on the right side of the screen aid in determining the depth of
targets. The line at the top of the screen represents the surface. The
bottom depth and surface temperature (if equipped with a temperature
sensor or a transducer with a temp sensor built in) show at the top left
corner of the screen.
The FasTrack™ display shows just to the right of the scale. This
changes all echoes into short horizontal bars, replicating a flasher so-
nar. The zoom bar on the far right shows the area that's zoomed when
the zoom is in use. (See the Zoom section for more information.)

are both set to the small text size.
