Marine Mode: Using Waypoints and Tracks
Marine Mode: Using Waypoints
and Tracks
Create waypoints in locations that you want to return to, such
as your marina or a good shing spot. You can store up to 1,500
marine waypoints with a user-dened name, symbol, depth, and
water temperature for each waypoint.
A track is a recording of your path. The track currently being
recorded is the active track. You can save your active track.
Using Man Overboard (MOB) Waypoints
Use a Man Overboard (MOB) waypoint to both create a waypoint
with an international MOB symbol ( ) and immediately begin
navigating to the MOB waypoint with a direct course (Go To).
To mark an MOB waypoint from the Home screen:
1. Touch Man Overboard. This immediately marks your current
position as an MOB waypoint.
2. Touch Yes to begin navigating to the MOB waypoint.
To mark an MOB waypoint from any other screen:
1. Touch Mark in the top-left corner of any screen except the
Home screen. This immediately marks your current position as
a waypoint.
2. Touch Man Overboard. This designates the waypoint as an
MOB waypoint and begins navigation automatically.
Marking a Waypoint at Your Current
Location
1. Touch Mark on any screen. This marks your current location as
a waypoint with an automatically generated name.
2. Choose from the following options:
• Edit Waypoint—designates a specic name, a symbol, a
water depth, a water temperature, or a position.
• Delete—deletes the waypoint.
• Man Overboard—designates the current location as a Man
Overboard (MOB) waypoint.
