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
decrease 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
ability to set it anywhere from zero to 100 percent. Once you select a
level in manual, the unit will continue to use that exact sensitivity set-
ting until you change it or revert to auto mode.
