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,

Automatic Identification System
The Automatic Identification System (AIS) enables you to
identify and track other vessels, and 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), 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.
4 Charts and 3D Chart Views
DRAFT
Symbol Description
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.
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.

Setting a Safe-Zone Collision Alarm
Before you can set a collision alarm, you must have a
compatible chartplotter connected to an AIS device or radar.
The safe-zone collision alarm is used only with AIS. The safe
zone is used for collision avoidance and can be customized.
1Select Alarms > AIS > AIS Alarm > On.
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.
2Select Range.
3Select a distance for the safe-zone radius around your
vessel.
4Select Time To.
5Select a time at which the alarm will sound if a target is
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 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 appear differently
on the chartplotter. Instead of tracking a SART transmission
for collision avoidance, you track a SART transmission to
locate and assist a vessel.

Radar
WARNING
The marine radar transmits microwave energy that has the
potential to be harmful to humans and animals. Before
beginning radar transmission, verify that the area around the
radar is clear. The radar transmits a beam approximately 12°
above and below a line extending horizontally from the center
of the radar. Avoid looking directly at the radar, because the
eyes are the most susceptible parts of the body.
When you connect your chartplotter to an optional Garmin
marine radar, such as a GMR 1206 xHD or a GMR 24 HD,
you can view more information about your surroundings.
The GMR transmits a narrow beam of microwave energy as it
rotates to a 360° pattern. When the transmitted energy
contacts a target, some of that energy is reflected back to the
radar.
Radar Display Modes
NOTE: Not all modes are available with all radar devices and
all chartplotters.
Select Radar, and select a mode.
Cruising Mode: Shows a full-screen image of the gathered
radar information.
Harbor Mode: Intended for use in inland waters, this mode
works best with short-range signals (2 nm or less).
Offshore Mode: Intended for use in open waters, this mode
works best with long-range signals.
Sentry Mode: Allows you to put the radar into timed-transmit
mode, in which you can configure a radar transmit and
standby cycle to conserve power. You can also enable a
guard zone in Sentry mode, which identifies a safe zone
around your boat. If you switch from Sentry mode to
another mode, the radar switches to full-time transmission
and disables all guard zones.
Radar Overlay Mode: Shows a full-screen image of the
gathered radar information on top of the Navigation chart.
The Radar overlay displays data based on the most-
recently used radar mode.
Transmitting Radar Signals
NOTE: As a safety feature, the radar enters standby mode
after it warms up. This gives you an opportunity to verify the
area around the radar is clear before beginning radar
transmission.

DRAFT
Adjusting the Zoom Scale on the Radar
Screen
The radar zoom scale, also called the radar signal range,
represents the distance from your position (the center) to the
outermost ring.
From a Radar screen, select or .
Each ring represents an even division of the zoom scale.
For example, if the zoom scale is set at 3 miles, each ring
represents 1 mile from the center out.
Tips for Selecting a Radar Zoom Scale
The radar zoom scale, or radar signal range, indicates the
length of the pulsed signal transmitted and received by the
radar. As the range increases, the radar transmits longer
pulses in order to reach distant targets. Closer targets,
especially rain and waves, also reflect the longer pulses,
which can add noise to the Radar screen. Viewing
information about longer-range targets can also decrease the
amount of space available on the Radar screen for viewing
information about shorter-range targets.
Determine what information you need to see on the
Radar screen.
For example, do you need information about nearby
weather conditions or targets and traffic, or are you more
concerned about distant weather conditions?
Assess the environmental conditions where the radar is
being used.
Especially in inclement weather, longer-range radar
signals can increase the clutter on the Radar screen and
make it more difficult to view information about shorter-
range targets. In rain, shorter-range radar signals can
enable you to view information about nearby objects more
effectively, if the rain clutter setting is configured
optimally.
Select the shortest effective range, given your reason for
using radar and the present environmental conditions.
Sentry Mode
Sentry mode allows you to put the radar into timed-transmit
mode, in which you can configure a radar transmit and
standby cycle to conserve power. You can also enable a
guard zone in this mode, which identifies a safe zone around
your boat and sounds an alarm when a radar object enters
the zone. Sentry mode works with all Garmin GMR model
radars.
Enabling Timed Transmit

to the last-used radar mode. For example, if you use Harbor
mode and then you switch to the Radar overlay, the Radar
overlay would show Harbor mode radar data. If you changed
the gain setting using the Radar overlay menu, the gain
setting for Harbor mode would change automatically.
Radar Overlay and Chart Data Alignment
When using the Radar overlay, the chartplotter aligns radar
data with chart data based on the boat heading, which is
based by default on data from a magnetic heading sensor
connected using a NMEA 0183 or NMEA 2000 network. If a
heading sensor is not available, the boat heading is based on
GPS tracking data.
GPS tracking data indicates the direction in which the boat is
moving, not the direction in which the boat is pointing. If the
boat is drifting backward or sideways due to a current or
wind, the Radar overlay may not perfectly align with the chart
data. This situation should be avoided by using boat-heading
data from an electronic compass.
If the boat heading is based on data from a magnetic heading
sensor or an automatic pilot, the heading data could be
compromised due to incorrect setup, mechanical malfunction,
magnetic interference, or other factors. If the heading data is
compromised, the Radar overlay may not align perfectly with
the chart data.
Showing the Radar Overlay
The Radar overlay displays data based on the most recently
used radar mode.
Select Radar > Radar Overlay.
The radar picture appears in orange and overlays the
Navigation chart.
Stopping the Transmission of Radar
Signals
From the Radar screen, select Menu > Radar to

Optimizing the Radar Display
You can adjust the radar display settings for reduced clutter
and increased accuracy.
NOTE: You can optimize the radar display for each radar
mode.
1Select a radar range (page 18).
2Restore the default value of the gain setting (page 18).
3Adjust the gain setting manually (page 19).
Range of Radar Signals
The range of the radar signal indicates the length of the
pulsed signal transmitted and received by the radar. As the
range increases, the radar transmits longer pulses in order to
reach distant targets. Closer targets, especially rain and
waves, also reflect the longer pulses, which can add noise to
the Radar screen. Viewing information about longer-range
targets can also decrease the amount of space available on
the Radar screen for viewing information about shorter-range
targets.
Radar Gain and Clutter
Automatically Adjusting Gain on the Radar Screen
Auto is the default value for the gain setting. The automatic
gain setting for each Radar mode is optimized for that mode,
and may differ from the automatic gain setting used for
another mode.
NOTE: Depending upon the radar in use, the gain setting
configured for use in one radar mode may or may not be
applied to other Radar modes or to the Radar overlay.
From a Radar screen or the Radar overlay, select Menu
> Gain > Auto.
The chartplotter sets the gain automatically once, based
on average conditions, the range of the radar signal, and
the selected radar mode. The chartplotter does not
readjust the gain automatically in response to changing
conditions.

DRAFT
Manually Adjusting Gain on the Radar Screen
For optimal radar performance that accounts for actual
conditions, you can manually adjust the gain.
NOTE: Depending upon the radar in use, the gain setting
configured for use in one radar mode may or may not be
applied to other Radar modes or to the Radar overlay.
1From a Radar screen or the Radar overlay, select Menu
> Gain.
2Select Up to raise the gain, until light speckles appear
across the Radar screen.
Data on the Radar screen is refreshed every few
seconds. As a result, the effects of manually adjusting the
gain may not appear instantly. Adjust the gain slowly.
3Select Down to lower the gain until the speckles
disappear.
4If boats, land, or other targets are within range, select
Down to lower the gain until the targets begin to blink.
5Select Up to raise the gain until the boats, land, or other
targets appear steadily lit on the Radar screen.
6Minimize the appearance of nearby large objects, if
necessary.
7Minimize the appearance of side-lobe echoes, if
necessary.
Minimizing Nearby Large-Object Interference
Nearby targets of significant size, such as jetty walls, can
cause a very bright image of the target to appear on the
Radar screen. This image can obscure smaller targets
located near it.
NOTE: Depending upon the radar in use, the gain setting
configured for use in one radar mode may or may not be
applied to other radar modes or to the Radar overlay.
1From a Radar screen or the Radar overlay, select Menu
> Gain.
2Select Down to lower the gain until the smaller targets
are clearly visible on the Radar screen.
Reducing the gain to eliminate nearby large-object
interference may cause smaller or distant targets to blink
or disappear from the Radar screen.
Minimizing Side-Lobe Interference on the Radar Screen
Side-lobe interference may appear to streak outward from a
target in a semi-circular pattern. Side-lobe effects can be
avoided by reducing the gain or reducing the radar range.
NOTE: Depending upon the radar in use, the gain setting
configured for use in one radar mode may or may not be
applied to other radar modes or to the Radar overlay.
1From a Radar screen or the Radar overlay, select Menu
> Gain.
2Select Down to lower the gain until the semi-circular,
streaked pattern disappears from the Radar screen.
Reducing the gain to eliminate side-lobe interference may
cause smaller or distant targets to blink or disappear from

Adjusting Sea Clutter on the Radar Screen
You can adjust the appearance of clutter caused by choppy
sea conditions. The sea clutter setting affects the appearance
of nearby clutter and targets more than it affects the
appearance of distant clutter and targets. A higher sea clutter
setting reduces the appearance of clutter caused by nearby
waves, but it can also reduce or eliminate the appearance of
nearby targets.
NOTE: Depending upon the radar in use, the sea clutter
setting configured for use in one radar mode may or may not
be applied to other radar modes or to the Radar overlay.
1From a Radar screen or the Radar overlay, select Menu
> Noise Rejection > Sea Clutter > Presets.
2Select a setting that reflects the present sea conditions.
3Select Menu > Noise Rejection > Sea Clutter.

clutter until other targets are clearly visible on the Radar
screen.
Clutter caused by sea conditions may still be visible.
Adjusting Rain Clutter on the Radar Screen
You can adjust the appearance of clutter caused by rain.
Reducing the radar range also can minimize rain clutter
(page 17).
The rain clutter setting effects the appearance of nearby rain
clutter and targets more than it effects the appearance of
distant rain clutter and targets. A higher rain clutter setting
reduces the appearance of clutter caused by nearby rain, but
it can also reduce or eliminate the appearance of nearby
targets.
NOTE: Depending upon the radar in use, the rain clutter
settings configured for use in one radar mode may or may
not be applied to other radar modes or to the Radar overlay.

Auto Guidance Line Configurations
CAUTION
The Safe Depth and Safe Height settings influence how the
chartplotter calculates an Auto Guidance line. If an area has
an unknown water depth or an unknown obstacle height, the
Auto Guidance line is not calculated in that area. If an area at
the beginning or the end of an Auto Guidance line is
shallower than the safe water depth or lower than the safe
obstacle height, the Auto Guidance line is not calculated in
that area. On the chart, the course through those areas
appears as a gray line. When your boat enters one of those
areas, a warning message appears.
NOTE: Auto Guidance is available with premium charts, in
some areas.
You can set the parameters the chartplotter uses when
calculating an Auto Guidance line.
Safe Depth: Sets the minimum depth (chart depth datum) the
chartplotter uses when calculating an Auto Guidance line.
Safe Height: Sets the minimum height (chart height datum)
of a bridge that your boat can safely travel under.
Shoreline Distance: Sets how close to the shore you want
the Auto Guidance line to be placed. The Auto Guidance
line may move if you change this setting while navigating.
The available values for this setting are relative, not
absolute. To ensure that the Auto Guidance line is placed
the appropriate distance from shore, you can assess the
placement of the Auto Guidance line using one or more
familiar destinations that require navigation through a
narrow waterway (page 29).
Adjusting the Distance from Shore
CAUTION
The Auto Guidance feature is based on electronic chart
information. That data does not ensure obstacle and bottom
clearance. Carefully compare the course to all visual
sightings, and avoid any land, shallow water, or other
obstacles that may be in your path.
NOTE: Auto Guidance is available with premium charts, in
some areas.
The Shoreline Distance setting indicates how close to the
shore you want the Auto Guidance line to be placed. The
