Zoom & Zoom Bar
Zooming the display is a common, fast and easy method used to enlarge
small detail, fish signals and the bottom. 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). When turned on, the 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.
To turn on the zoom bar, press
MENU|↓ to SONAR FEATURES|ENT. Press ↓
to
ZOOM BAR|ENT|EXIT|EXIT. Repeat these steps to turn it off.
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 to the normal display mode.
