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.
