The adaptation of a free nuclear precession magnetometer to the measurement of variations in declination as well as the magnitude of the earths magnetic field is discussed. The bias coil technique employed for these measurements offers a simple and accurate means for permanently recording such variations. Although equipment size was of secondary importance, results of this investigation indicate that a light weight declination variometer can easily be constructed.
