I do alot of back country hiking, hunting, etc. I have tried other compasses, even electronic compasses and gps. All are prone to problems with weather, satelite up links, etc.. even other manual compasses have let me down. But my suunto compasses have always worked just like a compass is supposed to work. Last I heard, they hadn't moved the north pole.
Pros: Steady neede, doesn't waiver when using it and walking. Great for hiking. User friendly for topo maps.
Cons: None that I've found.
