2.11.2 Fish school mode
The automatic echo target lock function automatically tracks the
operator-selected fish school. When menu option INTERLOCK on the TARGET
LOCK menu (Figure 2-17) 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.

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

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 tracking mode changes to position mode (see next
section) at that position.

When the FSV-24 detects and tracks the target again, the mode returns to
the fish school mode.
