The haunted house I’m going to later has you go through metal detectors before you can get in, but I want to bring a few tabs. The larger or closer the metal object in the ground is, the stronger the induced magnetic field will be, creating more electrical current in the receiver and a louder or stronger signal on the metal detector. It depends on how much aluminum foil and also on the configuration of the aluminum foil (i.e. Metal detectors do not work on magnetism, rather electrical conductivity.  Metal detectors do send magnetic pulses into the ground but they are not looking for magnetic items.  Without going too deep into the science, the magnetic pulses from the metal detector’s transmitter induce, or create, an electrical current in any metal objects in the ground. The detection threshold is then calibrated so that things like zippers and metal buttons aren't enough to set off the detector, but larger metal items will. Does aluminum foil block metal detectors and x-rays? 0 0 1. His opinion is that only lead will block x-rays. In the industry, to get aluminum foil, they take a big aluminum block and make it go through between enormous rollers several times until it becomes thinner enough.

They will be blocked by a solid and continuous substrate of metal (even just aluminum foil) but obviously the substrate itself will show up. This doesn’t mean that you can’t find valuable items made out of aluminum! If the buried treasure is very close to the large iron, the gold signal will be almost completely masked; The buried treasure would need to be 8-10″ minimum away from the large iron object before a typical metal detector would audibly separate them. It can detect all sorts of metals just like steel …. balled or flat). If the detector is picking up too much aluminum, try screening out the signals using discrimination or other features on the unit.
