A magnetic compass uses the poles of our planet to stay in alignment. A Gyroscopic compass is set to a particular direction and tends to try to stay that way. After time, even the best Gyro will start to precess (move). This means the you will need to compare your Gyro to the magnetic every 15 minutes or so. Some modern gyroscopic compasses are capable of auto resetting to do this update automatically.
