Explore our curated database of metal detector products tailored for utility locators, ensuring precision, efficiency, and reliability in the identification, mapping and protection of utility assets using metal detectors. 

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.

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

• Find utility meters and valves
• Locate sewers, stormwater drains, and other utility pits, lids, and hatches
• Identify manholes, septic tanks, and well casings 
• Locate objects under snow or water
• Trace barbed wire  
• Search areas along a chain-link fence
• Locate valve boxes
• Identify cast-iron pipes
• Locate steel drums
• Find ordnance and weapons
• Survey pegs, property markers

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.
