NOTE:
The sonar's depth capability depends on water and bottom condi-
tions, transducer installation and other factors.
Depth Range - Upper and Lower Limits
Virtually any segment of the water column can be displayed by using
the upper and lower limit feature. This lets you pick the deep and
shallow depth limits that are shown on the screen, provided there is at
least 10 feet between the upper and lower limits you select. For exam-
ple, a range from 12 feet to 34 feet could be used.
Changing the upper and lower limits gives you far greater control over
the depth range. This feature lets you "zoom in" the display with almost
unlimited combinations. Nearly any segment of the water column, from
the surface to the bottom can be shown. This enlarges the sonar targets
to best suit your fishing needs and water conditions.
