Charts and 3D Chart Views

The chartplotters have a basic imagery map. The charts and 3D
chart views listed below are available on the chartplotter. The
charts and views that are available depend on the map data and
accessories used.

You can access the charts and chart views by selecting Charts.
Navigation Chart: Shows navigation data available on your

pre-loaded maps and from supplemental maps, if available.
The data includes buoys, lights, cables, depth soundings,
marinas, and tide stations in an overhead view.

Perspective 3D: Provides a view from above and behind the

boat (according to your course) and provides a visual
navigation aid. This view is helpful when navigating tricky
shoals, reefs, bridges, or channels, and is beneficial when
trying to identify entry and exit routes in unfamiliar harbors or
anchorages.

Mariner’s Eye 3D: Shows a detailed, three-dimensional view

from above and behind the boat (according to your course)
and provides a visual navigation aid. This view is helpful
when navigating tricky shoals, reefs, bridges, or channels,
and when trying to identify entry and exit routes in unfamiliar
harbors or anchorages.

NOTE: Mariner's Eye 3D and Fish Eye 3D chart views are
available with premium charts, in some areas.

Fish Eye 3D: Provides an underwater view that visually

represents the sea floor according to the chart information.
When a sonar transducer is connected, suspended targets
(such as fish) are indicated by red, green, and yellow
spheres. Red indicates the largest targets and green
indicates the smallest.

NOTE: Mariner's Eye 3D and Fish Eye 3D chart views are
available with premium charts, in some areas.

Fishing Chart: Provides a detailed view of the bottom contours

and depth soundings on the chart. This chart removes
navigational data from the chart, provides detailed
bathymetric data, and enhances bottom contours for depth
recognition. This chart is best for offshore deep-sea fishing.

NOTE: The offshore Fishing chart is available with premium
charts, in some areas.

Radar Overlay: Superimposes radar information on the

Navigation chart or the Fishing chart, when the chartplotter is
connected to a radar. This feature is not available with all
models.

must turn on the Photo setting in the chart setup.

NOTE: This feature is available with premium charts, in some
areas.

You can use aerial photographs of landmarks, marinas, and
harbors to help orient yourself to your surroundings or to
acquaint yourself with a marina or a harbor prior to arrival.

From the Navigation chart, select a camera icon:

1

• To view an overhead photo, select .

• To view a perspective photo, select . The photo was
taken from the location of the camera, pointed in the
direction of the cone.

Select Review > Aerial Photo.

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), location, GPS speed, GPS heading, time that has
elapsed since the last position of the vessel was reported,
nearest approach, and time to the nearest approach.

AIS Targeting Symbols

Symbol Description

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.

Target is selected.

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 has been set to
Show. If the AIS transmission from the vessel is lost, a
message banner appears.

Target 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.

Dangerous target in range. The target flashes while an alarm
sounds and a message banner appears. After the alarm has
been 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 has been set to Off, the
target flashes, but the audible alarm does not sound and the
alarm banner does not appear. If the AIS transmission from
the vessel is lost, a message banner appears.

Dangerous 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.

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.

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. 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, course over
ground, or 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, the projected course 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 at the end of the heading
line. The length of the barb does not change.

Automatic Identification System

The Automatic Identification System (AIS) enables you to
identify and track other vessels, and alerts you to area traffic.

4 Charts and 3D Chart Views

When course over ground and heading information are provided
by an activated AIS target, but rate of turn information is not
provided, the projected course of the target is calculated based
on the course over ground information.

Showing AIS Vessels on a Chart or 3D Chart View

Before you can use AIS, you must connect the chartplotter to an
external AIS device and receive 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 are 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.

From a chart or 3D chart view, select Menu > Other Vessels

1

> AIS Display Setup.
Select an option:

2

• To indicate the distance from your location in which AIS
vessels appear, select Display Range, and select a
distance.

• To show details about AIS-activated vessels, select
Details > Show.

• To set the projected heading time for AIS-activated
vessels, select Projected Heading, and enter the time.

Setting the Safe-Zone Collision Alarm

Before you can set a safe-zone collision alarm, you must have a
compatible chartplotter connected to an AIS device.

The safe-zone collision alarm is used only with AIS. The safe
zone is used for collision avoidance, and can be customized.

Select Settings > Alarms > AIS > AIS Alarm > On.

1

A message banner appears and an alarm sounds when an
AIS-activated vessel enters the safe-zone area around your
boat. The object is also labeled as dangerous on the screen.
When the alarm is off, the message banner and audible
alarm are disabled, but the object is still labeled as
dangerous on the screen.

Select Range.

2

Select a distance for the safe-zone radius around your

3

vessel.
Select Time To.

4

Select a time at which the alarm will sound if a target is

5

determined to intersect the safe zone.
For example, to be notified of a pending intersection 10

minutes before it will likely occur, set Time To to 10, and the

alarm will sound 10 minutes before the vessel intersects the
safe zone.

AIS Distress Signals

Self-contained AIS distress signal devices transmit emergency
position reports when activated. The chartplotter can receive
signals from Search and Rescue Transmitters (SART),
Emergency Position Indicating Radio Beacons (EPIRB), and
other man overboard signals. Distress signal transmissions are
different than standard AIS transmissions, so they appear
differently on the chartplotter. Instead of tracking a distress
signal transmission for collision avoidance, you track a distress
signal transmission to locate and assist a vessel or person.

Navigating to a Distress Signal Transmission

When you receive a distress signal transmission, a distress
signal alarm appears.

Select Review > Go To to begin navigation to the
transmission.

AIS Distress Signal Device Targeting Symbols
