Depth Range
The Depth Range function controls the vertical distance displayed on the graphic area of the display.
There are 10 different depth ranges available. The top of the range is always 0, or the surface of the
water. Ranges of 0-15', 0-30', 0-60', 0120', 0-180', 0-240', 0-360', 0-480', 0-600', and 0-1000' are
available. The range which positions the bottom depiction closest to the bottom of the graphic area of the
display will best utilize the available display resolution.
user to adjust the current depth range setting. If no further button is pressed, the current depth range is
selected as the desired range and the unit returns to normal operation.
Using "Manual" Depth Range control, the user can view sonar information from the area near the surface
in great detail. If a depth range other than the current range is desired, pressing the DOWN ARROW to
highlight "Adjust" will allow selection of one of the 10 available ranges. Simply press and hold the UP or
DOWN ARROW button to scan through the available options. If a setting limit is reached, the audible
"error" or multiple chirps will be heard and no further adjustment is allowed. When "Manual" range is
used, the unit no longer adjusts the Depth Range to the most appropriate range for bottom display. Often,
the bottom may not be visible onscreen and a Bird Note TM will appear to indicate this condition. The
digital depth readout always determines the depth of the bottom, even if it is not visible onscreen.
When a Depth Range is selected manually and the Depth Range menu is still active (most recently used),
further adjustment of the depth range can be achieved by simply pressing the appropriate UP or DOWN
ARROW button. The button press will bring an abbreviated Depth Range menu on-screen located next to
the lower range number, and allows immediate adjustment of the range. After any adjustment is made, a
Bird Note will appear briefly to confirm the adjustment.
To return to "Automatic" Depth Range control, press the MENU button until the Depth Range menu
appears on-screen and use the UP ARROW to select AUTO. The Wide Paramount returns to Automatic
operation.
Note: Depth Range is not remembered when the unit is powered oft. At power up, the unit is always in
automatic depth range.
Zoom
The Wide Paramount uses a greatly enhanced Zoom capability called "TruZoom" which offers expanded
information on a select area of sonar information. 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 both vertically (depth information) and horizontally, and the unit's
ability to separate targets which are very close together is enhanced.
The Wide Paramount automatically adjusts the depth range
depending on the depth of the water. The unit tries to
maintain the bottom depiction about 2/3 down the total
range (for example, in 20' of water,
the 0-30' range would be selected). This provides the best
display resolution and therefore the best target separation
possible.
The Depth Range can be adjusted manually. Press MENU
repeatedly until the Depth Range menu is visible. The two
options available are "Auto" (Factory Setting) and "Manual".
Pressing the DOWN ARROW enables "Manual" depth range
control and an additional menu will appear which allows the
