Locating objects through magnetic field measurements with the MD200
The MD200 is perfectly suited for measuring changes in magnetic fields due to its two excitation coils and four receiver coils. The measuring device reacts with high sensitivity to the smallest changes of the terrestrial magnetic field, as it is influenced by ferromagnetic objects under the ground.
As you approach such an object with the MD200, the device indicates the increased signal both visually and acoustically.
For larger objects – for example manhole covers – the maximum values are generated at the object edges. By swinging the magnetometer and comparing the signal, the exact location can thus be determined.
