100 percent, but the unit will

limit your minimum setting. This prevents

you from turning sensitivity down too low to allow automatic bottom
tracking. When you change the setting with auto turned on, the unit will
continue to track the bottom and make minor adjustments to the sensi-
tivity level, with a bias toward the setting you selected.

Adjusting sensitivity in Manual Sensitivity Mode is similar to driving a
car without cruise control — you have

complete manual control of the

car's speed. In your unit, manual mode allows you to set sensitivity at
100 percent (maximum) or zero percent (minimum.) Depending on wa-
ter and bottom conditions, the bottom signal may completely disappear
from the screen when you reduce sensitivity to about 20 percent or less!

Try adjusting sensitivity in both auto and manual modes to see how
they work.
