Question 1

How do metal detectors work?

Accepted Answer

Metal detectors work by transmitting a magnetic field generated by coil a then analyzing that field as it returns from the environment that the signal was transmitted. The processing of the signal is done by a control unit that generates audio tones when it detects that the return signal has changed.

Question 2

Why and When using different coils on the metal detectors?

Accepted Answer

Using different coils for searching is a very self-explanatory process. We are using different sizes of coils for different opportunities. Bigger search coils (like 11" search coil) are often used for covering bigger areas quicker. Bigger coils also reach more depth so you can detect target deeper with smaller coils. But also that has its limits due to the law of physics. For example, if you use extreme sizes of coils like 50+ inch coils, it doesn't mean you can detect deeper areas, usually, coils can reach maximum depths of 2m. Bigger coils also do not perform well in a trashy environment, because they can detect multiple targets at once and its harder to determine which target is a witch We use smaller coils (like a 5" search coil) for more detailed searching, they also used for locating targets more accurately than bigger targets and perform much better in trashy environments. So we usually use bigger coils to cover large areas and then smaller ones to detect and locate targets more accurately.

Question 3

Can Metal detector tell you what the target is?

Accepted Answer

Of course, Every material has a specific number we call this scale of numbers Target ID value. Many factors influence on Target ID accuracies, like soil mineralization or angle between target and coil, by gaining experience in the field, you should be able to recognize many types of targets by Target ID value. Here is the table of ID values and object materials for it. Using 3D ground scan mode will also tell you targets the exact location, the shape of the target, and its size. Using augmented reality these details are displayed through smartphones directly on to word environment in real-time.

Question 4

Can metal detector tell depth?

Accepted Answer

Depth estimation is a very complex thing and it almost impossible to implement it to make perfect  due to these reasons: - There can be several targets at one place at a different depth, since the device is not able to know that, it takes into calculation the sum of all  - Objects come in different shapes, mass, and material, so it is hard to predict what exactly take into account   So a metal detector always displays the approximate depth of the object when the target is detected.

Question 5

What kind of objects can be discovered using metal detectors?

Accepted Answer

Precious metals like gold and silver, gold coins, gold nuggets, silver coins, jewelry, ancient bronze objects, world war findings.

Question 6

How does a gold metal detector not detect itself?

Accepted Answer

Because the search coil of the detector is always and it should always be extended away from a module of the detector. When the coil is extended it's surrounded only by carbon materials that's why it cant detect itself.

Question 7

Is metal detector safe?

Accepted Answer

Till now, there are no such cases reported about people suffering in one way or another after they have passed via a metal detector. Do metal detectors emit radiation? Yes, they do. But the energy that is emitted by a metal detector is not dangerous or harmful. In cases of walk through metal detectors, they use low-level x-rays which have been known to be harmless. These metal detectors are made considering human bodies. So it is understandable that there is no reason to worry about and the technology used in it is safe and harmless. To make your search more secure, please follow these precautions:   - never treasure hunt in a zone where bombs or other explosives may be buried, - never treasure hunt in an area where there might be underground electric lines or pipes buried at a shallow depth, - never treasure hunt in an area with flammable gas or liquid pipelines, - always use reasonable caution in digging, especially in areas where you are uncertain of underground conditions, - for safety reasons do not use headphones near traffic or other dangers like rattlesnakes.

Question 8

What's the correct use of your metal detector?

Accepted Answer

Soil contains iron minerals that can cause much higher signals than buried targets we are interested in. With ground balancing we calibrate the detector device to local ground, this eliminates false signals from minerals, enabling the detector to detect deeper and provide more accurate Target ID results. The ground balancing is performed in ALL METAL mode with the Gain position set to middle. The threshold needs to be set to the point where we can hear background hum. Find the place where is no metal presence in the ground. Press the GG button, then raise and lower the coil repeatedly over a clear patch of soil. When the GND PHASE value is settled down to 1 or 2 release GG button.

Question 9

Can metal detectors be waterproof?

Accepted Answer

Metal detectors can be waterproof, this is a very important feature, most of the detectors can be used in wet areas but this doesn't mean they can be used in the water. When we talk about waterproof metal detectors we refer to the search coil and the rod of the detector. This allows us to place the search coil in the water(rivers, streams, ponds).   But this kind of waterproof metal detector cant is used underwater when scuba diving.

Question 10

How to balance metal detector?

Accepted Answer

Firstly make sure that your metal detector is assembled correctly. Check smartphones and the detector's battery status. Adjust the length of the stem for a comfortable and relaxed body position when sweeping. It is very important that you learn how to sweep properly before using the detector:   Make sure that you read a quick start guide in the user manual and all other important notes. When you know basic operations, you can start scanning. Make sure that your smartphone is connected to the metal detector to exes all the advanced features. When the target is detected make sure to scan the same are from 90 degrees angels again to determine the exact location of the target. Use advanced features to determine the depth and material of the target before digging it. Don't forget to cover the hole after digging and leave the environment clean without causing any unnecessary damage.

Question 11

Is gold metal detector working in the house?

Accepted Answer

No, we don't recommend it. Because metal detectors are outdoor devices only and should not be used inside houses or next to electronic devices. If used indoors metal detector will not work properly and the results are gonna be fouls, due to interference with too much metal or third-party magnetization field.

Question 12

Where are the best places to use a metal detector?

Accepted Answer

After you buy your metal detector of choice you probably want to know where to start searching.   Well before going out to unknown territory or to places you think are potentials of finding something. We recommend you firstly sweep your backyard or Front YARD. For two main reasons. First, the Yards are an active place of movement many people have used this area before you, this means it can be a great place for containing some great lost objects form preview owners or your self. The second great thing is it can be your personal testing ground to learn how to properly use your new detector, you can test it and get to know all the features before going out on an adventure. The great alternative, if you don't own a Yard is to go to someone else yard (for example to your friend's yard or anyone you know, that has one).   Next and probably the most popular place is the BEACH. This is a very active place with very soft soil to dig. It's a great place of finding some precious lost items. But make sure that you get permission for this, usually, you can read about this on the internet. If you do it illegally you can face a fine. And make sure you don't disturb other people when searching with your metal detector.   Other great similar places to beaches are PARKS, FIELDS, WOODS, and FOOTPATHS. All these places are very similar to a beach, they are active places and can pose some great finds. Always make sure that you don't break any law or disturb natural habitat when searching.   Any active place where people move and spend free time can be great for searching. The other places where some historical actions take place al also great opportunities. Places like Battle sites usually poses a lot of objects that can be valuable. These places usually take some research about history to be found and located. Usually reading some books or reading some forums and local chat rooms will be very helpful to you.

Question 13

How deep does a metal detector detect targets?

Accepted Answer

The deepest that a metal detector can detect is approximately 1m or 40 inches. But detection depth depends on various circumstances, for example, the material and size of the target. The great factor in detection depth is soil material and its magnetization.

Question 14

Can an app turn your smartphone into a metal detector?

Accepted Answer

No, of course not. The smartphone can only be used as a displaying device.  You will need another external device like GoldHunter to work properly. And an application that supports it, like TresureHunet3d App.
