2D ZOOM - Manual Mode
The zoom feature works the same in manual as it does in automatic with
two exceptions. One, since the unit is in manual, the unit won’t change the
range to keep the bottom signal on the display. Two, you can adjust the
zoom “window” to any desired depth.
To zoom the screen in the manual mode, first press the ZOOM key. A
screen similar to the one on the previous page appears. You’ll notice a
new label on the screen: “ADJUST”. Press the key next to that label. A
screen similar to the one at right appears.
The unit is now in the split-
screen zoom mode. A zoom
bar is on the far right side of
the screen. Use the up and
down arrow keys to move this
bar up and down the right side

this bar shows on the left side

matically disappear.
You can have the zoom bar stay on the screen continuously, by using the
zoom bar menu. See the 2D Options in the MENUS section for more
information.

the unit can also show boat speed, distance travelled (log), surface water
temperature, and a surface water temperature graph in this area.
Next to the digital display box is the chart record. This shows depth infor-
