Shifting the Range
The basic range and range shifting functions
used together give you the means to select
the depth you can see on the screen. The ba-
sic range can be thought of as providing a
"window" into the water column and range
shifting as moving the "window" to the desired
depth.
Note:
This function is inoperative when the
Auto Range or Auto Shift is active.
1. Press
S
or
T
on the [SHIFT] key to show
the Shift setting window.
2. Use
S
or
T
on the [SHIFT] key to select
the amount of shift desired.
3. Press the [MENU/ESC] key to close the
window, or wait six seconds to automati-
cally close it.
Note 1:
The bottom echo may be lost if the
amount of shift is greater than actual depth.
Note 2:
"Auto Shift," which can be turned on
from the Sounder menu, automatically shifts
the range to keep the bottom echo on the
screen.
Note 3:
You can set the shift value for each
range independently, by turning on Free Shift
in the Sounder menu.
