I use both depending on where I am hunting and how far I am going. Most of the time I just use my compass. I always reference my compass when I use my GPS. Where I hunt in the river bottoms it will often take a GPS a few minutes to update when I start to walk out. However, you can take the bearing from the GPS and use the compass to start out on that bearing and the GPS will then catch up and update. If not the GPS you will often send you in the wrong direction for a couple of minutes until it updates and then send you in the right direction. In my case if I go the wrong direction for a couple of minutes it may cause me to have to cross a slough that is too deep to cross or go way out of the way to get to somewhere that I can cross. So I always carry both.
