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 some surface clutter.
Automatic Sensitivity
The default sensitivity mode is automatic. The unit bases the sensitiv-
ity level on water depth and conditions. When the unit is in the auto-
matic mode, sensitivity is automatically adjusted to keep a solid bottom
signal displayed, plus a little more power. This gives it the capability to
show fish and other detail.
However, situations occur when it becomes necessary to increase or de-
crease the sensitivity. This typically happens when you wish to see
more detail or when wave action and boat wakes create enough tiny air
bubbles to clutter much of the water column. In that case, a decrease in
sensitivity is indicated to reduce some of the clutter.
The control bar used to adjust sensitivity is the same whether the unit
is in the automatic or manual mode. In automatic you can adjust sensi-
tivity up to 100 percent but the unit will limit your
minimum setting.
In auto, 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
