Garmin Quickdraw
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 Quickdraw 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 indicates that the depth or GPS position data is
unavailable.
