The suspension compass was one the most important tools for the mine surveyor since the mid 17th Century. The gimballed compass is suspended on a wire allowing the compass to be in a horizontal position in any angle of inclination.

A similar mining compass by Andreas Wolf is in the collection of the Germanisches Nationalmuseum in Nuremberg, inventory-number W.J. 845. A drawing of this compass is illustrated in 'Mitteilungen aus dem Germanischen Nationalmuseum', 1886, fig. 22, p. 61.
