Instead, they sailed within sight of land in order to navigate. When that was impossible, ancient sailors watched constellations to mark their position.
How is compass useful to us?
The compass is used for navigation, location and direction. People use it to find their way, whether it is on a hiking trail or on a trip to a new location. Through a slight left or right turn, a compass will accurately point to the North Pole and identify the angles of the other cardinal directions.
