Automatic Identification System
The Automatic Identification System (AIS) enables you to identify and track other vessels.
About AIS
AIS alerts you to area traffic. When connected to an external AIS device, the chartplotter can show some
AIS information about other vessels that are within range, that are equipped with a transponder, and that are
actively transmitting AIS information. The information reported for each vessel includes the Maritime Mobile
Service Identity (MMSI), the location, the GPS speed, the GPS heading, the time that has elapsed since the last
position of the vessel was reported, the nearest approach, and the time to the nearest approach.

to the target indicates the heading of the target. The MMSI, speed, and direction of the
vessel appear beneath the target, if the details setting is set to
Show
(
page 14
). If the AIS
transmission from the vessel is lost, a message banner appears.

lost, and the chartplotter displays a message banner asking whether the vessel should
continue to be tracked. If you discontinue vessel tracking, the lost dangerous target
symbol disappears from the chart or the 3D chart view.
➌
AIS vessel. The vessel is reporting AIS information. The direction in which the triangle is
pointing indicates the direction in which the AIS vessel is moving.
➍
The location of this symbol indicates the closest point of approach to a dangerous target,
and the numbers near the symbol indicate the time to the closest point of approach to
that target.
➎
Dangerous target in range. The target flashes while an alarm sounds and a message
banner appears. After the alarm is acknowledged, a solid red triangle with a red line
attached to it indicates the location and the heading of the target. If the safe-zone
collision alarm is set to
Off
, the target flashes, but the audible alarm does not sound and
the alarm banner does not appear (
