2.11.2Fish school tracking mode

The automatic echo target lock function automatically tracks the operator-selected fish school. When menu option TILT INTERLOCK on the TARGET LOCK menu (previous page) is set to TILT & RANGE, and the tracked fish school goes out of the zone in the range direction, the range and tilt are automatically controlled according to the fish school position.

1.Select FISH at step 7 in the procedure in section 2.11.1.

2.Use the trackball to select the fish school to track on the horizontal display.

3.Press the [TARGET LOCK] key.

The target lock mark appears () on the fish school with a vector extending from its edge. This vector shows estimated target position after elapsed of preset vector time. The target lock mark is also inscribed on the vertical display, however no vector appears.

If the target is lost, the target lock mark changes to red color and the tracking mode changes to position mode (see next section) at that position.

When the FSV-84 detects and tracks the target again, the mode returns to the fish school mode.

4.To turn off the target lock, press the [TARGET LOCK] key again.
