Range
The Wide View adjusts the depth range automatically, so the bottom return is displayed
at the bottom 1/3 of the display. This leaves the top 2/3 to display anything between the surface
and the bottom. As your boat moves over deeper or shallower water, the unit adjusts the depth
range of the display to keep the bottom return in the same general area on the screen.
However, you may choose to control this range adjustment manually. By pressing
ENTER, you can select manual operation, meaning the unit will no longer adjust the depth range
automatically. The depth range selected is controlled by the UP and DOWN arrow buttons.
Ranges of 0-15', 30', 60', 120', 180', 240', 360', 480' & 600' can be selected. An onscreen icon
indicates whether the unit is in "AUTO" (automatic) or "MNL" (manual) range control.
If you alter the depth range, Manual operation is automatically selected. This feature is
valuable if you are only interested in targets near the surface. The Wide View will always display
the digital depth of the water, regardless of whether the bottom is shown on the selected depth
range.
Zoom
Another form of range control is Zoom.
Zoom allows selection of various ranges for full
screen viewing, while maintaining a view of the
full range. By using the display to view a smaller
area, the effective display resolution is
increased, and the units ability to separate
targets close together is enhanced.
The zoom range is determined by the
depth range in use when Zoom is enabled. In
shallow water, when the 15' or 30' depth range is
used, the zoom range will be 7-1/2'. If the 60' or
120' depth range is in use, the zoom range will
be 15', if a 180' - 480' depth range is used, the
zoom range will be 30', and if the 600' range is in use, the zoom range will be 60'.
To enable Zoom, adjust the horizontal lines to the depth of the zoom range using the UP
and DOWN arrow buttons, then enable Zoom using the ENTER button.
