Sensitivity & Auto Sensitivity
Sensitivity controls the ability of the unit to pick up echoes. 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 greater detail, but it can also clutter
the screen with many undesired signals. Typically, the best sensitivity
level shows a solid bottom signal with some surface clutter.
Automatic Sensitivity
The default sensitivity mode is automatic. The unit bases the
sensitivity level on water depth and conditions. When the unit is in
automatic mode, sensitivity is automatically adjusted to keep a solid
bottom signal displayed. This gives it the capability to show fish and
other detail.
There are situations when it becomes necessary to increase or decrease
sensitivity. This typically happens when you want to see more detail,
which requires a boost in sensitivity. But, when wave action and boat
wakes clutter the screen with tiny air bubbles, a decrease in sensitivity
is necessary.
The control bar used to adjust sensitivity up or down is the same
whether the unit is in the automatic or manual mode. In automatic you
can adjust sensitivity up to 100 percent but the unit will limit your
minimum setting. The unit will continue to make small adjustments,
allowing for the setting you selected.
In manual mode, you have complete control over sensitivity with the
ability to set it anywhere from zero to 100 percent. Once you select a
level in manual mode, the unit will continue to use that exact
sensitivity setting until you change it or revert to auto mode.
To adjust sensitivity in auto mode:
1. Press
MENU|ENT.
2. The Sensitivity Control Bar appears. Press to decrease sensitivity;
press to increase sensitivity. When it's set at the desired level, press
EXIT. (When you reach the maximum or minimum limit, a tone sounds.)
