2.11.2 Fish mode
The automatic echo target lock function automatically tracks the operator-selected
school of fish. When [TILT INTERLOCK] on the [TARGET LOCK] menu (previous
page) is set to [TILT & RANGE], and the tracked school of fish goes out of the zone in
the range direction, the range and tilt are automatically controlled according to the po-
sition of the school of fish.
1. Select [Fish] in the procedure in section 2.11.1.
2. On the horizontal display, use the trackball to select the school of fish to track.
3. Press the
TARGET LOCK key.
The target lock mark with vector is put on the school of fish. The color of the mark
is initially red, and turns white when the echo is recognized as a school of fish. The
vector shows the speed and direction of movement of the school of fish. The tip
of the vector is the estimated position of the school of fish when the vector time
elapses. The target lock mark appears on the vertical display, however the vector
is not shown.
If the target is lost, the target lock mark changes to red color and the tracking
mode changes to position mode (see the next section) at that position. When the
sonar detects and tracks the target again, the FISH mode is restored.
4. To disable the target lock, press the TARGET LOCK key.
