Garmin Quickdraw™ Contours
Mapping
The Garmin Quickdraw Contours mapping
feature allows you to create maps with
contours and depth labels to increase the
accuracy of existing maps.
When you record data using Garmin Quick-
draw Contours mapping, you should use
a Speed Class 10 memory card to ensure
that your device has enough processing
speed. The amount of saved data depends
on the size of your memory card, your sonar
source, and the speed of your boat as you
record data. You can record longer when you
use a single-beam sonar.
When Garmin Quickdraw Contours records
data, a colored circle surrounds the vessel
icon. This circle represents the approximate
area of the map that is scanned by each
pass. A green circle indicates good depth
and a good GPS position. A red circle indi-
cates that the depth or GPS position data is
unavailable.
You can view Garmin Quickdraw Contours in
a combination screen or as a single view on
the map.
When you record data on a memory card in
your chartplotter, the new data is added to
your existing Garmin Quickdraw Contours
map, and is saved on the memory card.
When you insert a new memory card, the
existing data does not transfer onto the new
card.
Mapping a Body of Water Using the
Garmin Quickdraw Contours Feature
Before you can use the Garmin Quickdraw
Contours feature, you must have a support-
ed chartplotter with upgraded software, so-
nar depth, your GPS position, and a memory
card with free space.
NOTE: This feature is not available on all
models.

Recording Offset: Sets the distance be-
tween the sonar depth and the contour
recording depth. For example, a sonar
depth of 3.6 m (12 ft.) with a recording
offset of -0.5 m (-1.5 ft.) creates contours
at a depth of 3.1 m (10.5 ft.).
Display Offset: Sets differences in contour
depths and depth labels on a Garmin
Quickdraw Contours map to compensate
for changes in the water level of a body
of water, or for depth errors in recorded
maps.
Survey Coloring: Sets the color of the
Garmin Quickdraw Contours display.
When the setting is turned on, successful-
ly recorded areas appear green, and un-
successfully recorded areas appear red.
When the setting is turned off, the contour
areas use standard map colors.
Automatic Identication System
The Automatic Identication System (AIS)
enables you to identify and track other
vessels, and alerts you to area trafc. 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 ap-
proach, and time to the nearest approach.
Some chartplotter models also support Blue
Force Tracking. Vessels being tracked with
Blue Force Tracking are indicated on the
chartplotter with a blue-green color.
AIS Targeting Symbols
Symbol Description
AIS vessel. The vessel is report-
ing 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 ap-
pears 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 contin-
ue 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 ashes 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 ashes, 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 indi-
cates 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.

12 Introduction
NOTE: Vessels being tracked with the Blue
Force Tracking feature are indicated with a
blue-green color regardless of their status.
Heading and Projected Course of Acti-
vated 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 tar-
get 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 project-
ed 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 acti-
vated 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 pro-
vided, 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 congure how other vessels appear
on a chart or on a 3D chart view. The display
range congured 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 congured for
one chart or one 3D chart view are applied to
all charts and to all 3D chart views.

Setting the Safe-Zone Collision Alarm
Before you can set a safe-zone collision
alarm, you must have a compatible chartplot-
ter 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.
1Select Settings > Alarms > AIS > AIS

Introduction 13
Alarm > On.
A message banner appears and an alarm
sounds when an AIS-activated vessel en-
ters 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 inter-
sect the safe zone.
For example, to be notied 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 Transmit-
ters (SART), Emergency Position Indicating
Radio Beacons (EPIRB), and other man
overboard signals. Distress signal transmis-
sions are different than standard AIS trans-
missions, 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 transmis-
sion, a distress signal alarm appears.
Select Review > Go To to begin naviga-
tion to the transmission.

Navigation with a Chartplotter
CAUTION
If your vessel has an autopilot system, a
dedicated autopilot control display must be
installed at each steering helm in order to
disable the autopilot system.
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.
When using Go To, a direct course and a
corrected course may pass over land or shal-
low water. Use visual sightings, and steer to
avoid land, shallow water, and other danger-
ous objects.
NOTE: Auto Guidance is available with pre-
mium charts, in some areas.
NOTE: Mariner’s Eye 3D and Fish Eye 3D
chart views are available with premium
charts, in some areas.
NOTE: The offshore Fishing chart is avail-
able with premium charts, in some areas.
To navigate, you must choose a destination,
set a course or create a route, and follow the
course or route. You can follow the course
or the route on the Navigation chart, Fishing
chart, Perspective 3D chart view, or Mari-

Introduction 17
ner’s Eye 3D chart view.
You can set and follow a course to a desti-
nation using one of three methods: Go To,
Route To, or Guide To.
Go To: Takes you directly to the destination.
This is the standard option for navigating
to a destination. The chartplotter creates
a straight-line course or navigation line
to the destination. The path may run over
land and other obstacles.
Route To: Creates a route from your location
to a destination, allowing you to add turns
along the way. This option provides a
straight-line course to the destination, but
allows you to add turns into the route to
avoid land and other obstacles.
Guide To: Creates a path to a destination
using Auto Guidance.
This option is available only when using a
compatible premium chart in a compatible
chartplotter. It provides a turn- by-turn
navigation line to the destination, avoiding
land and other obstacles. The navigation
line is based on the chart data and the
safe depth, safe height, and shoreline dis-
tance user-dened chartplotter settings.
Using these settings and chart data, the
chartplotter creates a navigation line that
avoids all areas that cannot be navigat-
ed between the present location and the
destination.
When you are using a compatible Garmin
autopilot connectedto the chartplotter
usingNMEA 2000®,the autopilot follows
the Auto Guidance route.

allows you to add turns into the route that
avoid land and other obstacles.
Guide To: Creates a path to a destination
using Auto Guidance.
This option is available only when using a
compatible premium chart in a compatible
chartplotter. It provides a turn- by-turn
navigation line to the destination, avoiding
land and other obstacles. The navigation
line is based on the chart data and the
safe depth, safe height, and shoreline
distance user-dened chartplotter set-
tings. Using these settings and chart
data, the chartplotter creates a navigation
line that avoids all areas that cannot be
navigated between the present location
and the destination. When you are using
a compatible Garmin autopilot connected
to the chartplotter using NMEA 2000, the
autopilot follows the Auto Guidance route.

Setting and Following a Direct Course
Using Go To
CAUTION
When using Go To, a direct course and a
corrected course may pass over land or shal-
low water. Use visual sightings, and steer to
avoid land, shallow water, and other danger-
ous objects.
You can set and follow a direct course from
your current location to a selected destina-
tion.
1Select a destination (Destinations, page
17).
2Select Navigate To > Go To.
A magenta line appears. In the center of
the magenta line is a thinner purple line
that represents the corrected course from
your current location to the destination.
The corrected course is dynamic, and it
moves with your boat when you are off
course.
3Follow the magenta line, steering to avoid
land, shallow water, and other obstacles.
4If you are off course, follow the purple line
(corrected course) to go to your destina-
tion, or steer back to the magenta line
(direct course).

Browsing for and Navigating to a
Saved Waypoint
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.
When using Go To, a direct course and a
corrected course may pass over land or shal-
low water. Use visual sightings, and steer to
avoid land, shallow water, and other danger-
ous objects.
NOTE: Auto Guidance is available with pre-
mium charts, in some areas.
Before you can navigate to a waypoint, you
must create a waypoint.
