I have been giving this some additional thought. To work, the magnetometer would have to be some kind of standoff distance from the team's vehicle. Going with something a kin to the fixed wing aircraft solution, the sensor could be mounted on a collapsible 3-4m pole that attaches to the body of vehicle, giving a final height of 4-5m above ground level. Driving with the sensor up would limit their speed and the types of terrain they could drive in. This does not stop them from doing measurements in rough areas, as they could go there with the sensor down, stop the vehicle, raise the mast, take the measurement, lower the mast, drive to the next location in the search grid and repeat. It would take probably 1-2 minutes to raise the mast, 1-2 minutes for the sensor to stabilize and take the measurement, another 1-2 minutes to lower and secure the mast with about 1 minute for general chaos running around the vehicle. So about 12 measurements per hour not counting travel time in rough terrain. There is still the 15m diameter blind spot directly below the mast caused by the large ferrous mass constantly there. This might be a suitable compromise for making the base a bit more difficult to find.
