Garmin Quickdraw Contours Settings
From a chart, select MENU > Quickdraw Contours > Settings.
Display: Displays Garmin Quickdraw Contours. The User 
Contours option shows your own Garmin Quickdraw 
Contours maps. The Community Contours option shows the 
maps you have downloaded from the Garmin Quickdraw 
Community.
Recording Offset: Sets the distance between the sonar depth 
and the contour recording depth. If the water level has 
changed since your last recording, adjust this setting so the 
recording depth is the same for both recordings.
For example, if the last time you recorded had a sonar depth 
of 3.1 m (10.5 ft.), and today's sonar depth is 3.6 m (12 ft.), 
enter -0.5 m (-1.5 ft.) for the a Recording Offset value.
User Display Offset: Sets differences in contour depths and 
depth labels on your own contours maps to compensate for 
changes in the water level of a body of water, or for depth 
errors in recorded maps.
Comm. Display Offset: Sets differences in contour depths and 
depth labels on the community contours maps 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 this setting is turned on, the colors 
indicate the quality of the recording. When this setting is 
turned off, the contour areas use standard map colors.
Green indicates good depth and GPS position, and a speed 
under 10 mph. Yellow indicates good depth and GPS 
position, and a speed between 10 and 20 mph. Red indicates 
poor depth or GPS position, and a speed above 20 mph.
Depth Range Shading: Specifies the upper and lower limits of a 
depth range and a color for that depth range.
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.
