Schonstedt GA-52B Spec TableSchonstedt GA-52B Survey Magnetic Locator
The Model GA-52B Magnetic Locator detects the magnetic field of a ferromagnetic object. lt responds to the difference in magnetic field between two sensors spaced about 20 inches apart. The response consists of a change in the frequency of a signal that is emitted by a loudspeaker. The figure below illustrates an application of the locator in which it is used to detect an iron marker for a property corner. In the illustration, the magnetic field of the iron marker is stronger at sensor A than it is at sensor B. As a result, the f requency of the signal on the loudspeaker is higher than the idling frequency,40Hz, which exists when the field is the same at both sensors.
