. The depth indicators now accurately show the water
depth beneath the keel.
NOTE:
If knowing the exact depth of water beneath the keel is less
important, you can calibrate the depth indicators so that they show
the actual water depth from surface to bottom. To do this, first
measure the distance from the face of the transducer to the surface
(the water line on the boat). In this example, we will use 1.5 feet. This
will be entered as a positive 1.5 feet, which makes the depth
indicators perform as if the transducer's higher in the water than it
really is.

Sensitivity & Auto Sensitivity
Sensitivity controls the ability of the unit to pick up echoes. A low
sensitivity level (from zero to 50 percent) excludes much of the bottom
information, fish signals, and other target information.

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 solid bottom signal with some surface clutter.
