Compass

A Compass is a navigational instrument used to determine the direction to go in areas requiring travel. It utilizes magnetics to determine the direction, and generally has the "N" on the rose to give the general sense of direction.

Usage
During the San Hieronymo Takeover and Peace Walker Incident, Big Boss and both his resistance group and Militaires Sans Frontieres, respectively, utilized an advanced compass that tracks sounds and enemy presences called the Surround Indicator.

The U.S. Army Hi-Tech Special Forces unit FOXHOUND utilized electromagnetic compasses throughout its various missions during the 1990s, of which it was developed as a result of monopole theory so it doesn't jam in areas such as jungles that jam other compasses.

During the Outer Heaven Uprising in 1995, Outer Heaven personnel utilized compasses when traversing on foot between Building 2 to Building 3, due to a lack of notable landmarks between the 20km stretch of desert between the two locations. Solid Snake, through resistance member Jennifer, managed to procure a compass to cross the distance, in exchange for aiding her in rescuing her brother from Outer Heaven mercenary Dirty Duck.

Compasses were later utilized during the War Economy.
