2.12 How to Track a School of Fish
The target lock function automatically tracks a school of fish so you will not lose sight
of it on the display. Two types of target lock are available: position tracking and track-
ing of school of fish. Select one from the menu as shown in the procedure that follows.
The default setting is tracking of school of fish. Speed and bearing data are required.
The FSV-75 cannot track a school of fish if the level of the echo is too weak.
This function requires appropriate data input. For details, see "DATA INPUT
REQUIREMENTS" on page AP-12.
Only one target lock can be active at any time.
Note: The target lock function is unavailable when the display mode is 3D, 3D & S or
3D & FF.
