C-turn
The AP25 provides a continuous turn feature when in AUTO
mode. This may be used for circling fish or a particular object on
the seabed.
C-turn makes the boat turn in a circle with a constant rate of turn.
The user decides whether the C-turn should be made to Port or to
Starboard.
Ensure that the C-turn pattern has been selected under the User
Set-up 2 menu. Refer to Turn Pattern select on page
55.
To enter C-turn mode:
First select U-turn with a press of the TURN/DODGE button.
Then select C-turn by another press of the TURN/DODGE
button.

The AP25 will continue on the set course until you
press either the PORT or STBD button to select the
direction in which to make the C-turn. If you do not
press PORT or STBD within 1 minute, the
autopilot will return to AUTO mode and stay on
course.
The turn rate can be adjusted before the turn is
initiated and during the turn. Increasing the turn rate
yields to a smaller circle and vice versa.
To exit C-turn mode, press any of the mode buttons.
When pressing the AUTO button, the new set
course is shown in the upper portion of the display.
