The term „metal detector” (MD) generally refers to some type of electromagnetic induction instrument, although traditional magnetometers are often used to find buried metal. The disadvantage of magnetometers is that they can be used only for locating ferrous metals. MD instruments in geotechnical and hazardous-waste site investigations have several uses.
The main advantages of MD instruments are that both ferrous and nonferrous metals may be detected; the surface area of the target is more important that its mass; and surveys are rapid, detailed, and inexpensive. These tools have given good results to identify the buried utilities, metal and non-metallic objects, buried unexploded bombs (UXO).
Applications of metal detector:
- Detection of buried tanks
- Detection of buried weapons
- Buried fuel tanks
- Detection of cables and pipelines
- Unexploded bombs (UXO)
- Identification of buried household objects
- Search anchors dragline excavators, etc.
- Follow itineraries pipes and ducts
- Submerged tanks and landfills
- Historical artifacts
