Presentation mode description
This sonar has four presentation modes, head-up, north-up, course-up and true mo-
tion. Select one with [Presentation Mode] in the [Others] - [Display Setting] menu.
Head-up
: The display is oriented toward ship’s heading. The heading direction ap-
pears at the top of the display. Own ship position is fixed at the screen center. Echoes
from fish and the bottom move on the screen relative to own ship’s movement. This
mode is useful for general use.
North-up
: The display is oriented so North is at the top of the screen. Own ship posi-
tion is fixed at the screen center and own ship mark pivots with ship’s movement.
Echoes from fish and the bottom move on the screen relative to own ship’s movement.
Course-up
: The display is oriented according to course. Own ship position is fixed at
the screen center. Echoes from fish and the bottom move on the screen relative to
own ship’s movement. Targets are displayed at ship’s bow.
True Motion
: Stationary objects are fixed and own ship and fish echoes move on the
display in accordance with their true courses and speeds. Thus you can observe own
ship and fish echo movement with respect to the bottom. This mode requires speed
and heading data. When own ship mark reaches an edge of the off-center effective
area it is automatically returned to the screen center as below.
