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 shallow and
deep depth range limits that are shown on the screen, provided there is
at least 5 feet between the upper and lower limit you select. For exam-
ple, a range from 12 feet to 34 feet could be used.
