feature off, press the menu key, then press the up or down arrow keys until
the FISH ID menu appears. Now press the left arrow key. Pressing it once

FishTrack on, press the right arrow key, which highlights the "TRACK"
label on the Fish ID menu.

screen. To do this, press the MENU key,
then press the up or down arrow keys until
the "CHART SETUP" menu appears. Now
press the right arrow key. The screen
shown at right appears.
The digital depth display at the top left
corner of the screen normally shows in
large numbers. You can change this to
smaller numbers or turn it off completely
using the "Show Digital" menu at the top of
this screen.
You can also turn the temperature, speedometer, distance log, zoom bar,
zone alarm bar,or cursor on or off using this menu. See below for more
information on these items.
CHART CURSOR
The Optima has a chart cursor that allows you to pinpoint a target’s depth.
The cursor is simply a horizontal line that extends across the display from
left to right. A depth box at the end of the line on the right side shows the
line’s depth. In the example at right, the
cursor (line) is at 29.8 feet.
To display the chart cursor, highlight the
"Show Cursor" on the "Chart Setup" menu,
then press the right arrow key. A screen
similar to the one at right appears. Use
the up and down arrow keys to move the
cursor up or down to the desired depth.
To turn the chart cursor off, repeat the
above steps. The Optima returns to the
sonar screen without the chart cursor.
