I have a Silva 15 Ranger, same one since 1977. Lost a previous one somewhere! I have a lot of experience with the military compass as well and do not particularly like them. I like the tritium and the 3 degree click bezel but hate the weight, way too heavy!
For my emergancy kit I carry an old Silva Huntsman. 5 degree marked but decent to navigate with.
I am curious why you would set a GPS to UTM? I prefer MGRS, which is what the military commonly calls UTM, although it is actually MGRS that the military uses. A note here is that if you ever call for a rescue by radio or cell phone, the best bet is to provide your position in lat/long since that is what most pilots navigate by. Mainly because they use smaller scale maps.
I seldom carry a GPS on hikes but I like having it in the car. A long hike and I may consider taking the GPS. I prefer to navigate the old fashion, non-battery dependant way. Cheers!
