Color Gain—controls what colors are applied to the objects on

the screen. Color DCG is based on depth and makes it easier to

spot subtle changes in bottom conditions or ﬁsh sizes. DynaColor

(default) represents the latest in sonar data presentation and is

recommended for all applications. The presentation is based on

bottom strength. It makes the bottom and the ﬁsh easier to see and

requires fewer adjustments.
Whiteline—controls how the unit shows information about the

bottom type (hard or soft). With the Whiteline Off, the bottom

return shows as red and contains no information on bottom

hardness. With Whiteline set at Normal or 1-100%, the bottom

return becomes white with a red line, in the default color scheme,

indicating where the water meets the bottom. To turn the Whiteline

Off, press the

ROCKER down until the setting bar is all the way at

the bottom of the range and reads Off. See

page 83

on this feature.
Frequency—allows you to choose a transducer frequency.

Frequency refers to the pitch of the sound that the transducer sends

and receives. You can choose 200kHz, 50kHz, or Dual frequency.

This option is only available if you have a dual frequency

transducer installed.

UltraScroll/Scroll—adjusts the rate at which the Sonar Pages

scroll from right to left. Ultrascroll (the default) is used when you

select a scroll rate from 90% to 100%. Auto automatically adjusts

the scroll rate according to the boat’s speed. (See also “Automatic

Scroll Speed Limit” on

Depth Line—adds a horizontal depth line across the screen that is

used to measure the depth of underwater objects. The depth of the

line appears in a box on the right side of the line. Press up or down

on the ROCKER to control the position of the line on the graph.

The depth shows in a window on the right side of the line. To turn

the Depth Line Off, press the ROCKER up until the setting bar is

all the way at the top of the range and reads Off.
