Brunton Ball & Socket anti-magnetic ball joint

This model, specially designed for Brunton compasses, is a safe and effective anchoring system that guarantees optimum stability of the measuring device on the tripod. Its structure is metallic, but anti-magnetic, to avoid that it can generate interference in the measurements. Its fastening system has a "U" shape and includes a lateral screw in one of its arms to facilitate the placement of the compass. The ¼ diameter thread securely links this sturdy, lightweight head with the tripod.
