Fish Finder Alarms

Two types of fish alarms release audio and visual alarms to tell you that echoes from
fish are in the area you selected. These alarms are [Fish Alarm] and [Fish Alarm for
Bottom Lock].
The [Fish Alarm] function tells you when an echo above some strength (selectable) is
within the alarm range you specify.
The [Fish Alarm for Bottom Lock] function tells you when fish are within some distance
from the bottom. The bottom lock display must be active to use this alarm.
