distance from the face of the transducer up to the surface (the water
line on the boat). In this example, we will use 1.5 feet. This will be en-
tered as a
positive
1.5 feet, which makes the depth indicators perform
as if the transducer's higher in the water than it really is.

Sonar Color Mode
The default color scheme for the sonar chart is grayscale, but we offer
other variations to suit your viewing preferences. You can select the
chart to be displayed in reverse grayscale, bottom black or FishReveal
mode. (For more information on FishReveal, see the entry on that topic
elsewhere in this section.)

Full Sonar Chart
This is the default mode used when the Sonar 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 the unit is 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.)
