Since you are just now moving your tent from the hotel room to the trail, I wonder how new you are to hiking & map use in general. I can't argue vs mapping GPS units since I haven't gotten one yet, but want to urge to get and use real paper topo maps early on. They will greatly aid the leaning how to translate reality--the dirt under your shoes & adjacent trees--to a mapmaker's (& SAR squad's) graphic/numeric depiction of where you are. I'm intimately familiar with some people who just can't do this spatial translation. I suppose with a good, walked, waypoint route you could push a button & follow a GPS arrow, but IMO it would be unsafe as a start. Far better to get used to "reading" a map first; what it can tell you and how it can suggest routes. The wonder of a map the size of a...map, not just the palm of your hand is the Big Picture it gives. In Utah of the wide-open-vista, you can enjoy that to the maximum.
I find the UTM grid on the map & coordinate reading on the GPS the easiest visual translation and 1,000m a useful unit on the ground. It used to be the compass function was a notorious battery hog. I always carry a real compass, too. But I have a partner here in CA who doesn't even carry that. It's pretty obvious in the wide open spaces which way is which, if you stay tuned into your environment and follow your map.
I've departed on a new mission. If you contain a GPS chip but won't tell me what that says, I ain't carrying you. Grinds me no end. ;)
