compass - / ˈkʌmpəs / -
verb
An instrument that indicates magnetic north and bearings from it. The compass comes in many forms, from an app on your phone to an old school free-pivoting magnetised needle. It doesn't really matter which type you prefer so long as it's reliable and you know where north is. Not to be confused with the device of the same name used by students to scratch their initials into desks and other furniture found in academic institutions.
\\ Some people can find true north using the stars or their wristwatch. I'm not one of those people, so I always carry a compass in the back country.
