Zoom & Zoom Bar
Zooming the display is a common, fast and easy method used to enlarge
small detail, fish signals and the bottom with its associated structure.
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.
Sonar Page normal view (left). Same view zoomed to 2X (center). Same

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 and turn on 2X or
4X Zoom. Then press ↑
↓ to pan up and down the water column.
