A magnetic compass can measure a boat's heading, or the direction it is moving.
A compass
A device commonly used to measure a boat's heading is a magnetic compass. This instrument indicates the direction relative to magnetic north. For more precise navigation, especially in larger vessels, a gyrocompass may also be used, as it is less affected by magnetic interference and provides true north readings. Modern boats may also utilize electronic heading sensors, which integrate with GPS and navigation systems.
This instrument is a balance.
