A GPS can be used in place of a compass but it should not elimiate a compass from your gear. A GPS is a more versatile navigation tool in that it can give you speed and distance as well as a precise location and accurate headings. However a GPS is less reliable because its batteries can die or water can get in to the electronics.

Learn how to use a compass and when you are navigating by GPS keep an eye on the compass to see how it agrees/disagrees with what the GPS is telling you. This way if your GPS dies mid-crossing you are prepared with enough backup info to use your compass.
