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 10 feet between the upper and lower limit you select. For ex-
ample, 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 in almost
unlimited combinations. Nearly any segment of the water column, from
the surface to the bottom can be shown.
