The used the stars in the night sky for navigation in darkness (using the north stars altitude to work out latitude) , the sun during the day. The first Western civilization known to have developed the art of navigation at sea were the Phoenicians, about 4,000 years ago (c. 2000 BC). Phoenician sailors accomplished navigation by using primitive charts and observations of the Sun and stars to determine directions. Some of the early instruments used to assist sailors in determining latitude were the cross staff, astrolabe, and quadrant. The astrolabe dates back to ancient Greece, when it was used by astronomers to help tell time, and was first used by mariners in the fifteenth century. It was used to measure the altitude of the Sun and stars to determine latitude.
Before the invention of the compass, people used landmarks, the stars, the sun, and knowledge of natural patterns like prevailing winds and currents to navigate. They also employed tools like astrolabes and cross-staffs to determine their position at sea.
People might use a compass when navigating in outdoor environments, such as hiking, camping, or boating, to determine their direction. A compass can help individuals orient themselves and find their way to a specific location by indicating the cardinal directions.
Before the invention of maps, people relied on landmarks, natural features like mountains and rivers, the positions of the sun and stars, and knowledge passed down through generations to navigate. They would use techniques like triangulation and dead reckoning to estimate their position and find their way.
"When you're through with that compass" is the complete adverb clause in this sentence. It begins with the subordinating conjunction "when" and provides information about the timing or condition under which the speaker may use the compass.
Compasses are used in a variety of modern applications, including navigation for hikers, backpackers, and wilderness enthusiasts, as well as in orienteering sports. They are also used in military and search and rescue operations, and as a backup navigation tool in case of technology failures. Additionally, compass apps are available on smartphones for everyday use.
European explorers used the compass as a navigational tool to determine their direction when traveling by sea. By utilizing the magnetic properties of the Earth, the compass helped sailors maintain their course and avoid getting lost during long voyages.

The earliest recorded actual use of a magnetized needle for navigational purposes then is to be found in Zhu Yu's book Pingzhou Table Talks (萍洲可談; Pingzhou Ketan) of 1119 (written from 1111 to 1117): The navigator knows the geography, he watches the stars at night, watches the sun at day; when it is dark and cloudy, he watches the compass. Thus, the use of a magnetic compass as a direction finder occurred sometime before 1044, but evidence for the use of the compass as a navigational device did not appear until 1119.
