an Electro Magnetic Detector from the 1930’s and was donated by Sun Oil.


The current mystery Item is an electro magnetic detector from the 1930s. It could also be called a geophone, a pick-up, or a seismometer.


It was probably used in seismic refraction work, but we don’t have any paperwork or reports that describe its use. This instrument was donated by Sun Oil, who was very active in the 1930’s and who donated many of our older instruments.
