Metal detectors use one of three technologies. Either very low frequency, pulse induction, and Beat-free oscillation.
Metal detectors work by creating an electromagnetic feild. This is done by running current through a coil at the head of the metal detector (the part you point at the ground). When there is metal, the changes in the magnetic feild are picked up by a second receiver coil.
What else can I help you with?
What kind of electrical sensor does a metal detector use?
One which responds to the disruption of a magnetic field.
How do stud detectors work and how can they help in locating studs behind walls?
Stud detectors work by detecting changes in density behind walls, typically caused by the presence of a stud. They use sensors to identify the location of studs, helping users find a secure spot to hang heavy objects or mount fixtures. This can prevent damage to walls and ensure that items are securely attached.
What is the difference between laser detectors and radar detectors?
Laser detectors detect laser beams used by law enforcement to measure speed, while radar detectors detect radio waves used by police radar guns. Laser detectors are more precise but have a shorter range compared to radar detectors. It's recommended to have both types of detectors for comprehensive coverage.

Are minelab metal detectors battery operated or rechargeable?
Minelab Metal Detectors currently makes their modern metal detectors rechargeable which is a lot better for the environment. The ones that take batteries die easier anyways.
Do zippers set off metal detectors?
Yes, zippers can set off metal detectors because they contain metal components that can be detected by the sensors.
Why were the house metal detectors removed?
