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 that will
show all echoes between the top and bottom of the 2X-zoom bar.
Pressing the key again will give a 4X zoom and only the echoes 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.

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 display up and down the zoomed area, allowing
you to focus on areas of interest in the water column below you.
To use Zoom Pan, switch to a Manual Depth Range setting (see page
61) and turn on 2X or 4X Zoom. Then press ↑ or
↓ to pan up and down
the water column.
