2. The Ping Speed Control Bar appears. Press
↓
to decrease ping speed
to 50 percent. When it's set at the desired level, press
EXIT
.
When you boost ping speed and switch into HyperScroll, the width of
the FasTrack bar graph display doubles in width at the right side of the
screen. This allows you to better see the virtually instantaneous sonar
returns, just as you would on a flasher sonar unit. For more informa-
tion on FasTrack, see it's entry in this section.
Reset Options
This command is used to reset all features, options and settings to their

Sensitivity & Auto Sensitivity
The sensitivity controls the ability of the unit to pick up echoes. Sensi-
tivity can be adjusted, because water conditions vary greatly. A low
sensitivity level (from zero to 50 percent) excludes much of the bottom
information, fish signals, and other target information.
High sensitivity levels let you see this detail, but it can also clutter the
screen with many undesired signals. Typically, the best sensitivity level
shows a good solid bottom signal with Colorline and some surface clutter.
