The central piece is cut into quadrants to provide indications at 0 and 90 degrees. This piece is capped with a thin nonmagnetic foil that is mounted in an adjustable spacer, allowing the test surface to be raised as a means of judging sensitivity. The Berthold Gauge has only gained popularity in the EU, while the Pie Gauge (W-PG) is by far the most popular aid for determining Field Direction. MPI Accessories
