Man Overboard (Mob) Navigation - Humminbird 900 Series Installation And Operation Manual

Man Overboard (MOB) Navigation

As soon as you know that you have a man overboard, you should activate
MOB navigation to maximize chances for a successful rescue. MOB
navigation allows you create an MOB waypoint to locate the point at which
your man went overboard, and the relation of the boat to that point. When
MOB is activated, an MOB waypoint, which is a permanent, sharable
waypoint with a large, distinctive icon, is created at the boat's current
position (regardless of whether the chart cursor is active or not). Any current
navigation will be cancelled and the current route discarded without user
notification, and MOB navigation will begin immediately. A line will be
drawn from the boat's current position to the MOB waypoint, and the MOB
waypoint will be targeted. The view is switched to the Chart View
automatically when MOB is activated, and an additional info box that shows
the lat/lon position of the MOB waypoint and the elapsed time since MOB
was activated is added to the Chart View.
It is not possible to re-activate MOB or modify the current route without first
canceling MOB navigation. The Off Course trigger is also disabled and the
Off Course Alarm circle is not drawn. Any press of the GOTO key, or selection
of a GOTO menu item, will cause an error beep and a short message will be
displayed to the user that will disappear after 2 seconds.
Activate MOB navigation: Press and hold the GOTO key for more than 1.5
seconds to activate the Man Overboard (MOB) function.
Cancel MOB navigation: From the Navigation X-Press™ menu, select
Cancel MOB and press the RIGHT Cursor key. Canceling MOB navigation
removes the route and any waypoints created using the GOTO key, but does
not remove any saved routes from memory.
