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 once doubles the size (2X) of all echoes on the screen.
ZIN
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 key is pressed.
ZIN
For example, pressing the key once will enable a 2X zoom which
ZIN
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.

Zoom Pan

Your unit has the handy ability to quickly zoom in on any portion of the
water column with just the touch of an arrow key. The Zoom Pan feature
lets you rapidly move the zoomed area up and down to different depths.
By "pointing" your zoom at different portions of the chart as it scrolls, you
can get a good, close-up look at structure or cover below you.
To use Zoom Pan, switch to a manual depth Range setting (see page 67)
and turn on 2X or 4X Zoom. Then, simply press ↑ to pan up and down
↓
the water column.
