Zoom & Zoom Bar
"Zooming" the display is a common, fast and easy method used to en-
large small detail, fish signals and bottom structure. This unit lets you
zoom in 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 blue zoom
bar on the far right side of the screen shows which echoes will be dis-
played 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 be displayed.
Press the Zoom Out key,
ZOUT, to return the display to the normal mode.
