11.3 Range
The Range and Range Shift functions enable you to change
the range of depth displayed on-screen. Changes to the Range
and Range shift will apply to both the Sonar and DownVision
applications.
Range
The Range function enables you to define the range of depth
that you see on-screen.
By default, the range is set to automatic, this adjusts the range
to ensure the bottom is always displayed on-screen. This is
useful for locating bigger fish and other objects located closer
to the bottom such as wrecks
There may be circumstances in which you want to see a more
detailed image showing less depth beneath your vessel. This is
useful for finding smaller fish that feed nearer the surface
Range Shift
The Range Shift function enables you to define which area of the
overall depth you want to be able to see on-screen. For example,
if your range is 250 feet and the display is showing the surface
(0 feet) at the very top of the display, and 250 feet at the bottom
of the display, you can use the Range Shift function to focus on
a different 250 feet range. For example, 20 feet at the very top
of the screen, and 270 feet at the very bottom of the screen.
Changing the depth range
You can choose from either:
• automatic adjustment whereby the display automatically
shows the shallowest required range.
• manual adjustment of the depth range, up to the maximum
depth.
From the application menu:
1. Select Range .
2. Select Range to switch between Auto and Man.
3. With manual mode selected you can now use the Rotary
control to adjust the depth range shown on-screen.
Note: With the Range menu displayed you cannot use the
Rotary Control to range in and out. To use the Rotary
control to range in and out, first close the Range menu.
Using range shift
The default setting adjusts the display to keep the bottom in the
lower half of the display window. Alternatively you can shift the
image within the current range. Changes to the range shift are
reflected in all windows.
