The Basics of Metal Detectors
Metal detectors can be a great way to find hidden treasures, but they can also be a nuisance if you’re trying to hide something from them. This article will cover the basics of metal detectors and how you can hide gold from them.
How Metal Detectors Work
All metal detectors work on the same principle. A Metallic object will reflect a magnetic field, whereas other materials will not.
A typical metal detector consists of a control box, which houses the battery and electronic components, and a search coil, the part of the machine you hold above the ground. The search coil is connected to the control box by a cable, and as you move it over the ground, it generates a magnetic field.
When the coil passes over a metallic object, it disturbs the magnetic field, which is detected by the circuitry in the control box and produces a signal. This signal is then amplified and sent to a speaker in the control box, which emits a tone that becomes louder as you get closer to the object.
Different Types of Metal Detectors
There are four basic types of metal detectors: beat-frequency oscillation (BFO), induction balance (IB), pulse induction (PI), and transformer coupled (TR). Beat-frequency oscillation is the oldest and most common type of technology. It operates by transmitting an electromagnetic field into the ground and receiving a signal proportional to the soil’s conductivity. The most common form of BFO metal detector uses two separate transmitter-receiver coils that are electrically connected. One coil, called the transmitter coil, produces a magnetic field, while the other, called the receiver coil, is used to receive signals emitted from objects within the magnetic field.
The advantage of BFO detectors is that they are relatively simple and inexpensive. The disadvantage is that they are also more prone to false signals than other detectors.
Induction balance (IB) metal detectors work on the principle of electromagnetic induction. This type of detector uses two coils — one for transmitting and one for receiving — that are wound around each other. When an alternating current is passed through the transmitter coil, it produces a magnetic field. If there is any conductive material within this field, it will emit its magnetic field that the receiver coil can detect. The advantage of IB detectors is that they can discriminate between different types of metals based on their conductivity. The disadvantage is that they are more complex and expensive than BFO detectors.
Pulse induction (PI) metal detectors work on a similar principle to IB detectors, but they use a single coil for both transmitting and receiving. When an electric current is passed through the coil, it produces a magnetic field. If there is any conductive material within this field, it will emit its magnetic field that the coil can detect. The advantage of PI detectors is that they can operate in environments with a lot of mineralization, such as on beaches with salt water. The disadvantage is that they are more expensive than BFO or IB detectors.
Transformer-coupled (TR) metal detectors use two coils — one for transmitting and one for receiving — that are wound around each other like in an IB detector. However, instead of being electrically connected, these coils are magnetically coupled. This means that when an alternating current passes through the transmitter coil, it produces a changing magnetic field which induces a current in the receiver coil. If there is any conductive material within this field, it will emit its magnetic field, which the receiver coil can detect.

Hiding Gold from Metal Detectors
There are several ways to hide gold from metal detectors at home, but some are more effective than others. One common method is to bury the gold in a location that is not likely to be disturbed, such as in the foundation of a house or a potted plant. Another option is to wrap the gold in a non-metal material, such as cloth or paper.
Ways to Hide Gold
Gold isn’t just for jewelry. You can also hide it around your house where a metal detector wouldn’t think to look.
Here are a few hiding spots for your gold:
-In the crevices of a large piece of furniture, like a couch or bed frame.
-Inside an empty shampoo bottle or another toiletry item in your bathroom.
-Taped to the bottom of a heavy, metal object like a lamp base or stapler.
-Underneath the floorboards or behind loose tiles.
Tips for Hiding Gold
With the popularity of metal detecting, it’s only natural that people want to find ways to hide their valuables from these prying eyes. While there are several ways to do this, some are more effective than others. If you’re looking for tips on how to hide your gold from metal detectors, here are a few things to keep in mind.
- One of the most important things to remember is that gold is an excellent conductor of electricity. This means that if you wrap your gold in a material that is not a conductor, it will be much harder for a metal detector to pick up. Aluminum foil is a good option, as are rubber and plastic.
- Another way to reduce the chances of your gold being detected by a metal detector is to break it into smaller pieces. The smaller the pieces, the harder it will be for the detector to pick up on them.
- If you have the opportunity, bury your gold. This is one of the most effective ways to hide it from detectors, as they will have a harder time picking up on small objects buried underground.
- Finally, keep in mind that metal detectors are not 100% accurate. There is always a chance that one can pick your gold up, even if you follow all of these tips. However, by reducing the likelihood of detection, you can increase your chances of keeping your valuables safe and hidden.
- Advanced Methods for Hiding Gold.
- Let’s say you have found gold, or you have gold that you want to keep safe from thieves. How do you hide it from metal detectors? The most obvious answer is to bury it, but there are other ways. Here are some advanced methods for hiding gold.
- Using a Faraday Cage.
- A Faraday cage or Faraday shield is an enclosure that blocks electromagnetic fields. A Faraday shield may be formed by a continuous covering of conductive material or, in the case of a Faraday cage, by a mesh of such materials.
To create a Faraday cage, you need three things: metal screen wire, solder, and a soldering iron. Once you have those three things, the process is pretty simple. First, cut the wire into pieces that will fit snugly around your gold item—you don’t want any gaps. Then, solder the pieces of wire together. Finally, use the soldering iron to create a “cage” around your gold piece by Soldering the wire to itself.
Once you’ve created your cages, you can store them in different places around your house. Just be sure to keep them away from areas with strong magnets (like near speakers) or electronic devices that give off EMF fields (like TVs and microwaves).
Creating a Metal-Free Zone
If you have other metal detectors in your household, create a metal-free zone where you can safely hide your gold. This can be done by demagnetizing the area with a degaussing coil.
You will need the following:
-A degaussing coil
-A non-magnetic container
Instructions:
- Run the degaussing coil over the area where you hide your gold. This will remove residual magnetism and create a haven for your precious metals.
- Place your gold into the non-magnetic container. This could be a glass jar, Tupperware, or even an envelope. Make sure that the container is closely sealed so that there is no risk of your gold falling out.
- Store the container safely, out of sight, and away from potential thieves.
