Zoom
Zoom is similar to Depth Range in that it controls the range of information displayed in the
graphics area of the display. Zoom, however, allows selection of ranges beneath the surface so
any area of water between the surface and the bottom can be enlarged to provide more detailed
information. By using the full display to show a small area of coverage, the effective display
resolution is increased, and the unit’s ability to separate targets which are very close together is
enhanced.
There are four different Zoom ranges available; 7 ½ feet, 15 feet, 30 feet, and 60 feet. These
ranges are not directly user controlled but are instead dependent on the current depth range. In
shallow water, when the 15 foot or 30 foot range is in use, the Zoom range is 7 ½ feet. If the 60
foot or 120 foot range is in use, the Zoom range is 15 feet. If a 180 foot-480 foot depth range is in
use, the Zoom range is 30 feet, and if the 600 foot range is in use, the Zoom range is 60 feet.
It is not possible to use Zoom in conjunction with he Monster Digits view. While the Monster Digits
view is always available, Zoom information is only displayed on the 2D view.
The Wide Portrait shows Zoom range in conjunction with the full depth range. The Zoom range is
shown on the left side of the screen and full range information is shown on the right side of the
display. Zoom can either operate automatically, in which the Zoom range is constantly adjusted to
show the bottom, or manually, in which the user controls the location of the Zoom Range.
“Automatic” Zoom is especially helpful when looking for structure or bottom detail. The
“Automatic” Zoom keeps the bottom in view even in quickly changing terrain. “Manual” Zoom
provides detailed information of any area from the surface to the bottom. In “Manual” Zoom, the
Zoom range does not move as the terrain changes.
To operate Zoom, press MENU repeatedly until the Zoom menu is on-screen. Three options are
available: “Off(Factory Setting), “Auto” (Automatic bottom tracking Zoom), and “Manual” (User
controlled Zoom range). Press the DOWN ARROW once to highlight Auto.
