A green circle indicates good depth and GPS position, and a speed under
16 km/h (10 mph). A yellow circle indicates good depth and GPS position, and
a speed between 16 and 32 km/h (10 and 20 mph). A red circle indicates poor
depth or GPS position, and a speed above 32 km/h (20 mph).
You can view Garmin Quickdraw Contours in a combination screen or as a
single view on the map.
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. It is estimated that you might be
able to record about 1,500 hours of data onto a 2 GB memory card.
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.
