What is Electrical Interference
Electrical Interefernece is the distortion in magnetic field caused by surrounding metallic objects or systems having electricity running through them. If those structures are close enough to get the magnetism of the gold detectors. Then by absorbing eddy currents they will emit a magnetism of their own which would in return effect the functionality of a gold detector.
Sources of Electrical Interference
Large metallic objects or a network of wires or pipes held above the ground will cause significant distortion in detectors because the medium of conduction is air. Includes the metal from wirings, pipings, construction structures, etc.
The metallic objects buried underground also have a significant impact on creation of electrical interference for the metal detectors and gold detectors. These could include underground wiring systems, underground piping and sewage systems, underground transportation routes etc.
Electrical perimeter fences
The metallic fences built around sensitive buildings for security having harsh edges on top and electrical current flowing through them are also a very important indicator or actor inducing electrical interference.
The network of landline telephone cables laid around below the ground or above can cause electrical interference for the gold detecors as well.
Heavy Metallic Objects
Other heavy metallic objects including vehicles for transportation because of their ignition systems, military level communication home based or commercial level computer systems, old CRT-based televisions having comtinous explosions of electrons in the machine, portable cell phones and hand held devices, natural thunderstorms with huge outbursts of electrons, some metal vapor lamps, elaborate military aircraft with electronic warfare countermeasures turned on, daily use electric motors, VLF military communications systems etc.
Built-in Noise from Detectors
Although most of the hardware in the gold detectors is made from non metallic items such as wood and quality plastic, as conduction of electric current is required, it cannot be done without some metallic conductors in the form of the coil, wires attached to the battery and the battery itself. This can cause a built in noise from detectors.
Wireless Communication technology
Bluetooth, wifi and network connectivity in the modern day cell phone also have the potential to distort the gold detectors via electrical interference and it becomes challenging for the gold detector users because such devices are usually very helpful in the field for connectivity but the mobile phones along with other portable and helpful devices must be kept away to ensure maximum possible sound or noise cancellation.
