Tip:
For quicker sensitivity adjustments, leave the Sensitivity Control
Bar on the screen as the chart scrolls. You can see the changes on
the screen as you press the up and down arrows. This is handy
when there is a lot of clutter in the water and you are matching the
sensitivity to rapidly changing water conditions.
