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-25/FSV-25S can not track a school of fish if the level of the echo is too weak.
