4.4 Man Overboard (MOB)
If you lose a person or object overboard, and need to return to the location, you
should use the Man Overboard (MOB) function immediately.
Note: To obtain an MOB position, you need either of the following:
• Position data from a GPS or equivalent device
• Heading and speed data, so that the position can be calculated by dead
reckoning
You can select the type of data used for the MOB position using the Set Up
Menus (see
Chapter 7 ).
➤
To initiate the MOB procedure, press and hold the
MARKS
key for two
seconds.
The Pathfinder Radar then performs all the following tasks automatically:
• Switches the range scale to ¼nm.
• Marks the current position with a MOB symbol .
The MOB waypoint replaces any current active waypoint and route.
• Displays the MOB data box, showing the bearing and distance from your
vessel to the MOB waypoint position, and the elapsed time since the MOB
was initiated.
• As your vessel moves away from the MOB position, a dotted line is
displayed connecting the MOB position and the vessel’s current position.
