A digital compass uses an electricity to create a magnetic field. The earth’s magnetic forces push and pull that magnetic field causing electrons to pile up in certain areas. The digital compass reads where the electrons pile up and can tell which way you are pointing in relation to the external magnetic force.
This is called the Hall Effect. Just like a normal compass, any chunk of metal, magnet, electric field, or other interference with the earth’s magnetic forces will corrupt the digital compass’s reading.
A digital compass can quickly give a bearing and is easier to read since it shows degrees as numbers rather than a dial that you need to interpret and estimate the degrees. It is also faster since you don’t need to wait for the compass needle to spin around and settle into its final direction.
