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.

About AIS Search and Rescue Transmitters
AIS Search and Rescue Transmitters (AIS-SART, or SART) are self-contained devices that transmit 
emergency position reports when activated.  SART transmissions are different than standard AIS transmissions, 
so they look different than standard AIS symbols on the chartplotter. Instead of tracking a SART transmission 
for collision avoidance, you track a SART transmission to locate and assist a vessel.
Navigating to a SART Transmission
When you receive a SART transmission, a distress signal alarm appears.
Select  Review > Go To to begin navigation to the SART transmission.
AIS Targeting Symbols
Symbol Description
➊AIS Target is activated. The target appears larger on the chart. A green line attached 
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.
➋Dangerous target is lost. A red X indicates that the AIS transmission from the vessel is 
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. 
➌AIS 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.  
						

							GPSMAP 700 Series Owner’s Manual 13
Charts and 3D Chart Views 
➍The 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. 
➎Dangerous 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 (page 15). If the AIS transmission from the vessel is 
lost, a message banner appears.
➏Target is lost. A green X indicates that the AIS transmission from the vessel is lost, and 
the chartplotter displays a message banner asking whether the vessel should continue to 
be tracked. If you discontinue vessel tracking, the lost target symbol disappears from the 
chart or the 3D chart view. 
Target is selected.
AIS-SART transmission. You can select this symbol to see more information about the 
SART transmission and begin navigation.
AIS-SART transmission lost.
AIS-SART transmission test. This symbol appears when a vessel initiates a test of their 
SART device, and does not represent a true emergency. You can disable these test 
symbols and alerts (page 14)
AIS-SART transmission test lost.
Heading and Projected Course of Activated AIS Targets
When heading and course over ground information are provided by an activated AIS target, the heading of the 
target appears on a chart as a solid line attached to the AIS target symbol. A heading line does not appear on a 
3D chart view.
The projected course of an activated AIS target appears as a dashed line on a chart or a 3D chart view. The 
length of the projected course line is based on the value of the projected heading setting ( page 14). If an 
activated AIS target is not transmitting speed information, or if the vessel is not moving, a projected course 
line does not appear. Changes in the speed, the course over ground, or the rate-of-turn information transmitted 
by the vessel can impact the calculation of the projected course line.
When course over ground, heading, and rate of turn information are provided by an activated  AIS target 
➊, the 
projected course 
➋ of the target is calculated based on the course over ground and the rate of turn information. 
The direction in which the target is turning, which is also based on the rate of turn information, is indicated by 
the direction of the barb 
➌ at the end of the heading line ➍. The length of the barb does not change.

ground information.

From the Home screen, select  Configure > other Vessels > AIS SART Test.
Showing AIS Vessels on a Chart or on a 3D Chart View
AIS requires the use of an external AIS device and active transponder signals from other vessels.
You can configure how other vessels appear on a chart or on a 3D chart view. The display range configured 
for one chart or one 3D chart view is applied only to that chart or to that 3D chart view . The details, projected 
heading, and trails settings configured for one chart or one 3D chart view are applied to all charts and to all 3D 
chart views.

An optional, preprogrammed BlueChart g2 Vision data card allows you to get the most out of your chartplotter. 
In addition to detailed marine charting, BlueChart g2 Vision has the following features:
• Mariner’s eye 3D (page 17)—provides a view from above and behind the boat for a three-dimensional 
navigation aid. The BlueChart g2 Vision Mariner’s Eye 3D is more detailed than the pre-loaded data.
•  Fish eye 3D (page 18)—provides an underwater, three-dimensional view that visually represents the 
sea floor according to the information on the chart.
•  Fishing Charts (page 19)—shows the chart with enhanced bottom contours and without navigational data. 
This chart works well for offshore deep-sea fishing.
•  High Resolution Satellite Imagery  (page 20)—provides high-resolution satellite images for a realistic 
view of the land and water on the Navigation chart.
