Upper and Lower Limits
You can enter virtually any combination of ranges when the unit is in the
manual mode. The unit lets you enter any upper and lower limit, provided
there is at least ten feet separating them. (On the screen below left, the
upper limit is 0 and the lower limit is 100.) Using the upper and lower limit
range option, we changed the range from 0 to 100 feet to 30 to 55 feet.
This “zoomed” the display to a 35 foot range.

ZOOM
“Zooming” the picture is a common method used to enlarge small detail
and fish signals. To zoom the screen, simply press the ZIN (zoom-in) key.
This enlarges all echoes on the screen to twice their normal size. To re-
turn the screen to 2X or normal, simply press the ZOUT (zoom-out) key
until the desired zoom appears. When the unit is in zoom, “2X” appears in
the lower right corner of the screen, showing the current zoom mode.
