What are 9 Frequently Asked Questions About Metal Detectors

Frequently Asked Questions About Metal Detectors

There are many queries that beginners or detectorists have in their minds about metal detectors. Before investing in an actual metal detector, they wish to clear their ambiguities.

Today, we will remove your uncertainties and try our best to give you a clear understanding of metal detectors.

Our research here will address frequently asked questions about metal detectors. Now we will move on to our selection of the most important queries concerning metal detectors.

Frequently Asked Questions About Metal Detectors

What are metal detectors?

Metal detectors are electronic instruments that find hidden metal items in the ground, water, or air.

What do metal detectors detect?

Metal detectors can detect many types of metals, like iron, gold, silver, brass, copper, aluminum, nickel, cobalt, and metal alloys. Stainless steel is one example of a synthetic metal alloy.

People search for gold nuggets, coins, relics, and treasures as target objects. Relics contain metallic weapons, statues, and utensils that have historical significance. Besides this, treasure entails the collection of coins, relics, or both.

What do metal detectors not detect?

People are keen to collect precious gemstones such as diamonds, sapphires, rubies, and other precious rocks. However, detecting gemstones with a metal detector is an impossible task.

Basic metal detectors often overlook metals that have low electrical conductivity and few magnetic properties. Furthermore, non-metals such as plastic and wood are also untraceable with a metal detector.

How do metal detectors work?

Firstly, the coil of the metal detector generates an electromagnetic field into the ground. Next, these electromagnetic forces interrupt the EMF of hidden metals.

After the interruption, the EMF of the target metal becomes energized. Later, these energized metal signals are captured through the detector.

The metal detector then identifies the metal presence by displaying a response on the control unit. Plus, the audio tone also indicates the target’s existence.

How much does a metal detector cost?

The price of a metal detector depends on the model of the device. If you are inclined to go for a beginner device, then its price range will start from US $300.

You can obtain a decent advanced-level device with prices ranging from US $1000-2000. The amount of money you are investing in metal detection should be according to your dedication level in this hobby.

How deep does a metal detector detect?

Some manufacturers exaggerate the depth potential of their devices, but in reality, the opposite is true. For example, a manufacturer may claim to its customers that their device can provide an extreme depth of several kilometers.

If someone wants to know how deep it can go, the answer is that it depends on the detector’s coil. Along with the coil, the detector’s frequency also matters.

The lowest frequencies will penetrate deep underground. For example, 1 KHz will go deep underground in comparison to 10 kHz.

It is impossible for an 11-inch coil to detect at a depth of 4 meters. An 11-inch search coil can only give you a depth of 1.5 meters, and beyond this, it will be impossible to receive signals.

You must never disregard that the depth depends on the coil size. The larger the coil, the greater the depth potential, while the smaller coil offers a lower potential.

Overall, metal detectors cannot offer a depth of more than 5 to 6 meters. The reason is that current technology cannot perform beyond this depth.

Why are metal detectors so expensive?

Metal detectors are based on intricate technology that continuously evolves. They are not basic home appliance instruments.

That’s why they are normally more expensive than regular electronics. Furthermore, you will have a lot of options depending on the manufacturer.

If the product is branded, then you will surely get a warranty. Even though they are pricey, they provide good value for money.

On the contrary, there are duplicate products of authentic brands that come with cheaper prices and zero performance.

So as a purchaser, you must bear in mind to always buy from a manufacturer or authorized distributor; otherwise, you will face a huge loss.

What is the difference between a metal detector and a gold detector?

A metal detector is a generic device that serves to detect metals such as gold, silver, copper, iron, nickel, aluminum, etc . Its main function is to detect metals and is not specialized to provide discrimination features.

On the other hand, a gold detector is specifically designed to differentiate between different metals. You can reject particular metals and discriminate against ferrous metals. Similarly, the frequency feature is optimized in such a way as to pick up gold (a low conductor).

What are long-range locators?

Long-range locators are based on pseudo-science. These are deceptive types of devices that are used to mislead innocent customers. They claim to detect hidden metals, but they are fake, fraudulent, and unreliable.

You should never trust these devices. If, by chance, you see a device with limited hardware, you must realize that this device can’t send signals underground.

We strongly suggest that you do not buy long-range locators to save your effort, time, and money.

Conclusion

Many people have queries about metal detectors and their functions. We have aimed to answer the most important and frequently asked questions about metal detectors. We hope that you are now clear about most of your ambiguities.
