Abstract: This report covers results of the long-term research directed at developing an absolute vector proton magne-tometer based on the switching of bias magnetic fields. The distinctive feature is the attempt of the installation of a miniature Overhauser sensor and optimized Garret solenoid directly on the telescope of the theodolite. Thus this design (Declination Inclination Modulus Overhauser magnetometer: DIMOVER) will complement the uni-versally recognised DIflux absolute device by adding full vector measurement capability. Preliminary designs, which also can be interesting to the experts in vector proton magnetometers, are presented.
Key words: Overhauser magnetometer, magnetic observatory instrumentation, DIflux, magnetic declination, magnetic inclination.
