In this example, we're setting the upper limit.
Use the up and down arrow keys to select the
number, the right and left arrow keys to move
to the next number. When the limit shows the
desired depth, press the ENT key. The screen
shown below appears.
As you can see, the upper limit has changed
from 0 to 35 feet. With the lower limit remain-
ing at 60 feet, this gives a "zoom" of 25 feet.
If you want to change the lower limit, repeat
the above steps, press the right arrow key on
the "Set Chart Limits" menu, and change the
lower limit to the desired value.
Changing the upper and lower limits gives
you far more control of the screen than com-
petitive sonar products. You can select any
segment of the water from the surface to the bottom, enlarging targets to
best suit your fishing conditions.
ZOOM
“Zooming” the picture is a common method used to enlarge small detail and
fish signals. The unit gives you two different zoom sizes, plus a split screen
zoom option. The zoom operation and adjustment is different in the
automatic and manual modes.
ZOOM - AUTOMATIC MODE
To zoom the screen in automatic mode, simply press the ZIN (zoom-in)
key. This enlarges all echoes on the screen to
twice their normal size. If you press the ZIN
key again, the screen is "zoomed" to four
times normal size. To return the screen to 2X
or normal, simply press the ZOUT (zoom-
out) key until the desired zoom appears.
When the unit is in the 2X or 4X zooms, "2X"
or "4X" appears in the lower right corner of the
screen, showing the current zoom mode.
