Set Man Overboard (MOB) Waypoint
One of boating's most terrifying events is having a friend or family
member fall overboard. This situation can be deadly on any body of wa-
ter — fresh or salt. It's particularly dangerous at night or if you're out
of sight of land. Of course, the first thing to do is remain calm and then
use all standard safety procedures to rescue the person.
This unit has a man overboard feature that shows navigation data to
the location where the feature was activated. To activate it, press the
ZOUT and ZIN keys at the same time. Your position at the time these
keys are pressed is used as the man overboard position.
Caution:
Saving a new "Man Overboard" waypoint will overwrite and
erase the previous "Man Overboard" waypoint.
Navigate Back to MOB Waypoint
Find your way back to the accident position with the Navigation Page
or Map Page. When MOB is activated, the Navigation Page automati-
cally shows the compass rose with its bearing arrow pointing toward
the man overboard position, and the destination name says "Going To
Man Overboard." The Map Page displays a Man Overboard waypoint,
represented by a human figure, and the steering arrow points where to
steer to reach that position.
Navigating to Man Overboard: "Man Overboard activated" message
shown at left. The Navigation Page is shown in the center and Map
Page is shown at right. The victim is astern of the vessel; the GPS
shows which direction to steer to for the rescue.
