Claim 0:
1. A geodetic assembly for land surveying, said geodetic assembly including:
a first element including a first magnetic unit, said first element being attached to a geodetic device; and
a support structure including a second element adapted to mate with said first element for supporting said geodetic device;
wherein the second element includes a second magnetic unit arranged to interact with said first magnetic unit for locking or unlocking said first element on said support structure;
wherein each of said first magnetic unit and said second magnetic unit is divided in a plurality of regions arranged in a circular manner such that two adjacent regions have magnetic poles of opposite polarities;
wherein said first magnetic unit is rotatable relative to said second magnetic unit such that the first element is brought in a locked position in which north and south poles of the second magnetic unit are in alignment, or at least or at least approximately in alignment, with south and north poles of the first magnetic unit, respectively, and in an unlocked position in which north and south poles of the second magnetic unit are in alignment, or at least approximately in alignment, with north and south poles of the first magnetic unit, respectively; and
wherein said geodetic assembly further comprises at least one magnetic shield for shielding said geodetic device from said first magnetic unit and said second magnetic unit.
