This mode expands bottom and bottom fish on
the left-half window. This mode is useful for
determining bottom contour. When the bottom
depth increases, the display automatically shifts
to keep the bottom echo at the lower part of the
screen.

Marker zoom display
This mode expands chosen area of the normal
picture to full vertical size of the screen on the
left-half window. You may specify the portion to
expand by operating the VRM (Variable Range
Marker), which you can shift with
S
or
T
. The
area between the VRM and zoom marker is
expanded. This mode is useful for determining
the size of fish in the middle water.
