Begin Treasure Hunt with Metal Detector

People will associate it with mine detectors when talking about metal detectors, engineers use it to detect buried mines. Metal detector is an instrument designed to detect metal, except for the detection of the mine have a metal or metal parts, it can also be used to detect the wires concealed in the walls, pipes and cables buried in underground, even underground treasure-hunting and found metal objects buried in the ground, of course, more metal detectors are now used in industrial purposes, such as food metallic contamination detection - Food metal detector, machine factory security metal detector - metal detector door, security door, Textiles metal impurities Broken Needle Detection - Needle detector and so on. Metal detectors can also serve as the equipment for youth national defense education and science activities, of course, after all is a fun entertainment device.



Theory of Metal Detector
Metal detectors use electromagnetic induction principle, using a coil with alternating current through, to produce a rapidly changing magnetic field. The magnetic field can be induced eddy currents in the metal object. Eddy currents will produce magnetic field, the magnetic field upside down affect the original magnetic field, triggering an audible warning signal in detector.



Underground Metal Detector
Is the application of advanced technology production, it have features like wide degree of detection, positioning accuracy, strong discernibility, ease operation and so on. Metal detector is mainly used to detect and identify hidden metal objects buried underground. besides used in military applications, is also widely used for: security checks, archeology, mineral prospecting, looking for scrap metal. Againreferred to as "Iron Exploration" is a good helper of waste recycling.



Hand-held Metal Detector
Hand-held metal detectors are designed to detect metal objects carried by people or objects. It can detect weapons, explosives or small metal objects in parcels, baggage, letters, fabric, etc carried by person. Its special appearance of the sensitive surface to make the operation simple and easy. Better than the ring-type hand-detection sensors. Ultra-high sensitivity, use for specific applications, such as prisons, chip plants, archaeological research, hospitals.
