4.4 Man Overboard (MOB)
Ifyou lose apersonor objectoverboard,and need to returnto 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 Section 7.3).
➤ To initiate the MOB procedure, press and hold the MARKS key for two
seconds.
The Pathfinder Plus Radar then performs all the following tasks
automatically:
• 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
vesselto theMOB waypoint position,and theelapsed timesince theMOB
was initiated.
• Displays the position data box, showing your vessel’s position.
• As your vessel moves away from the MOB position, a dotted line is dis-
played connecting the MOB position and the vessel’s current position.
• Sounds a 4-second alarm pattern every 30 seconds.
• Sends an MOB message to other units in the system, via the SeaTalk con-
nection.
