Automatic Sensitivity
The default sensitivity mode is automatic. The unit bases the
sensitivity level on water depth and conditions. When the unit is in the
automatic 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.
Situations occur, however, when it becomes necessary to increase or
decrease sensitivity. This typically happens when you wish to see more
detail, so an increase in sensitivity is needed. Or when wave action and
boat wakes create tiny air bubbles that clutter much of the water
column. In that case, a decrease in sensitivity is necessary to reduce
some of the clutter.
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. 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
setting until you change it or revert to auto mode.
