Using a compass in Greenland involves accounting for a very extreme magnetic declination. Failure to calculate correctly can send a hunter in the wrong direction, leading to complete loss of bearings. Getting lost in bad weather can waste precious time, forcing the hunter to overnight in very wet, cold, and unpleasant conditions. Hypothermia can further complicate matters and decrease the hunter's ability to think clearly, causing them to lose their bearings even more. A fight for survival may then ensue. Deaths are relatively rare, but they do happen.
