πŸ€” Theory of Metal Detector Utility Locating

Metal detectors serve a variety of essential use cases in utility locating.

Walk-through portable metal detectors are the most frequently used metal detectors for detecting the presence of metallic objects. They can save time locating utility meters, metal obstructions, utility boxes and manhole covers. They perform well, when locating in long grass or in snow covered conditions. 


How do metal detectors work?

Metal detectors work by transmitting an electromagnetic field from the search coil into the ground. Any metal objects (targets) within the electromagnetic field will become energized and retransmit an electromagnetic field of their own.


When the electromagnetic field of the transmitted wave impinges on a conducting object, it induces transient currents on the surface of the object; these currents, in turn, radiate electromagnetic waves. These secondary waves are sensed by the detector coil.


Do Metal detectors detect both ferrous and non-ferrous metals?

Yes,  They detect ferrous metals more easily due to their magnetic properties. Ferrous metals contain iron and are often magnetic.


Non-ferrous metals, such as nickel, aluminum, and zinc, consist of other elements and are not magnetic, But can still be detected with a metal detector.

βœ… Utility Locating and Surveying Applications

Metal detectors serve a variety of essential use cases in utility locating.

  • Find utility meters and valves πŸ—œοΈ
  • Locate sewers, stormwater drains, and other utility pits, lids, and hatches πŸ•³οΈ
  • Identify manholes, septic tanks, and well casings 
  • Locate objects under snow or water ❄️
  • Trace barbed wire  πŸ”—
  • Search areas along a chain-link fence ⛓️
  • Locate valve boxes πŸ—œοΈ
  • Identify cast-iron pipes πŸ”©
  • Locate steel drums πŸ›’οΈ
  • Find ordnance and weapons πŸ’£
  • Survey pegs, property markers πŸ“

In challenging environments, such as areas covered in snow or submerged in water, metal detectors prove valuable in saving time by locating metal objects efficiently.  


Metal detectors are also used for their ability to locate ordnance and weapons, making them indispensable tools across a spectrum of locating needs.


Furthermore, magnetic locating excels in tracing barbed wire, searching along chain-link fences, and identifying valve boxes, cast-iron objects/pipes, and steel drums.
