1.6 Automatic Operation
How automatic operation works
The automatic function automatically
chooses the proper gain, range scale
and clutter. It works as follows:
• The range changes automatically to
display the bottom echo on the
screen.
• The gain is automatically adjusted to
display the bottom echo in the darkest
tone.
• Clutter (on the menu), which
suppresses low-level noise, is
automatically adjusted.
Choosing automatic operation
The automatic mode provides two
choices of modes: cruising and fishing.
1. Press the [MENU/ESC] key to open
the main menu.
2. Press ▲ to choose AUTO MODE
from page 1 of the menu.
3. Press ► to open the mode options
window.
4. Choose Cruising or Fishing as
appropriate.
“Cruising” is for tracking the bottom;
“Fishing” is for searching fish schools.
Since “Cruising” uses a higher clutter
rejection setting than fishing, it is not
recommended for fish detection -
weak fish echoes may not be
displayed. “Fishing” clearly displays
weaker echoes.
