ZOOM

"Zooming" the picture is a common method used to enlarge small detail and
fish signals. The Optima 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
The only way to zoom the screen in automatic mode is to 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 Optima
is in the 2X or 4X zooms, "2X" or "4X" appears in the lower right corner of
the screen, showing the current zoom mode.
