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 re-
quired.The FSV-85 MARK-2 cannot track a school of fish if the level of the echo is too
weak.
One target lock mark is shown. For the Horizontal 2 and Slant combination displays,
the mark is shown on the applicable display. The target lock mark does not appear on
the displays where it can not be inscribed.
