4.12 Tracking a Fish School (target lock)
The target lock function automatically tracks a fish school so you won’t lose sight
of it on the display. Two types of target lock are available: position tracking
(TARGET MARK) and fish school tracking (FISH) and you may select one from
the menu as below. Default setting is “FISH.” However, if the FSV-84 cannot
receive an echo of sufficient level of echo, tracking may not be performed.
