What is the main advantage of gyro compass?

How does a compass work?
A compass works by detecting the Earth’s natural magnetic fields. … This allows the needle to better react to nearby magnetic fields. Since opposites attract the southern pole of the needle is attracted to the Earth’s natural magnetic north pole. This is how navigators are able to discern north.
Is Al magnetic?
In our everyday experience aluminum doesn’t stick to magnets (neither does copper). … Most matter will exhibit some magnetic attraction when under high enough magnetic fields.
