What are the parts of a metal detector?
An industrial metal detector consists of four main components: the sensor, the control, the signal processor, and the output device.
How do metal detectors work simple explanation?
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 energised and retransmit an electromagnetic field of their own.

What is the principle of metal detector?
The operation of metal detectors is based upon the principles of electromagnetic induction. Metal detectors contain one or more inductor coils that are used to interact with metallic elements on the ground.
How deep can metal detectors detect metal?
Most metal detectors can detect objects about 4-8ʺ (10 – 20 cm) deep. In ideal conditions, a mid-range metal detector can reach 12-18ʺ (30-45 cm) underground. Some specialized detectors can go as deep as 65′ (20 m).
What metals Cannot be detected by a metal detector?
Metal detectors have a tough time detecting metals like stainless steel, which have very poor electrical conductivity. Stainless steel has low magnetic permeability, which means it does not produce a signal strong enough to be detected. Other items that metal detectors won’t be able to locate include: Gemstones.
How deep do metal detectors go?
What do metal detectors actually detect?
Metal finders’ more accurate term is: Metal Detectors, as the metal detector’s main function is to detect the presence of metal objects including for example underground buried metal targets such as gold treasures, bronze statues, archaeological artifacts made of different metal types.
How deep do most metal detectors go?
Most metal detectors can reach 6-8ʺ (15 – 20 cm) deep, on average. Some specialty metal detectors can go up to 65ʹ (20 m) deep.
