Zoom & Zoom Bar
"Zooming" the display is a common, fast and easy method used to en-
large small detail, fish signals and the bottom with its associated struc-
ture. This unit lets you zoom the display quickly and easily by pressing
the Zoom In key,
ZIN
.
Pressing
ZIN
once doubles the size (2X) of all echoes on the screen.
Pressing it again quadruples the size of the echoes (4X). The zoom bar
on the far right side of the screen shows which echoes will be displayed
on the screen when the
ZIN
key is pressed.
For example, pressing the
ZIN
key once will enable a 2X zoom which
will show all echoes that are between the top and bottom of the 2X
zoom bar. Pressing the key again will give a 4X zoom and only the ech-
oes between the top and bottom of the 4X bar will show on the screen.
Press the Zoom Out key,
ZOUT
, to return the display to the normal mode.
