I have a GPS but I still carry a compass and topo maps in unfamiliar areas.
Batteries fail. Electronics get wet or damaged.
Compasses always work.

I memorize my maps when going into an unfamiliar area. Another trick is to turn around every 200 yards or so and look at your back trail. If you don't and have to back track, nothing will look familiar and you will get lost...
Try hunting elk in the blue mountains some time; when you do that a few times, it gives a whole new meaning to the word "hunting".
