To select the zoom depth:
1. From the Home screen, select Full
Screen > MENU > Zoom Depth.
2. Select Manual Zoom Depth or Auto
Zoom Depth. If you select Manual
Zoom Depth, press right or left on the

2. Select Off or On. If you select On,
press up or down on the ROCKER
to adjust the depth line, then press
SELECT.
Sonar Setup
To change the sonar settings:
From the Home screen, select Full
Screen > MENU > Sonar Setup.
Color Scheme—select White or Blue.
This affects the background on sonar
screens.
Fish Symbols—sets how the sonar
interprets suspended targets.
Suspended targets appear as
symbols with background
information shown, making the distinction
between sh and structure easier.
Suspended targets appear as
symbols with background
information shown. The target depth of
each symbol is also indicated.
Suspended targets appear as
symbols with no background
information shown.
Suspended targets appear as
symbols with no background
information shown. The target depth of
each symbol is indicated.
Scroll Speed—adjusts the rate at
which the sonar scrolls from right
to left (Ultrascroll, Fast, Medium,
or Slow). If using a speed-capable
transducer, select Auto to have the
scroll speed automatically adjust to the
water speed of the boat.

Surface Noise—shows or hides the sonar returns near the surface of the water. Hide
surface noise to help reduce visual clutter.
Whiteline—highlights the strongest signal from the bottom to help identify the
hardness or softness of the targets. High is the most sensitive setting. Almost all
strong returns are highlighted in white. With a Low setting, only the strongest returns
are highlighted in white.
Keel Offset (visible only if a speed wheel is not attached; see Transducer, below, if
a speed wheel is attached)—offsets the surface reading for the depth of a keel so you
can measure depth from the bottom of the boat keel instead of from the transducer.
Enter a positive number to offset for a keel. You can enter a negative number to
compensate for a large vessel that may draw several feet of water. Use the ROCKER
to adjust the offset, then press SELECT.

Understanding the Flasher
Screen
From the Home screen, select Flasher to
display sonar information on a circular depth
scale. The scale indicates what is beneath
your boat. It is organized as a ring that starts
at the top and progresses clockwise. Sonar
information ashes on the ring when it is
received at the depth indicated. The colors
indicate different strengths of the sonar
return. (When using the white default color
scheme, red indicates the strongest return,
blue indicates the weakest return, and white
indicates no return.)
