What is a Metal Detector?

A metal detector is a digital device that has the potential to discover the presence of metal in walls, soil, water, or on any other surface without physical contact. Technically, if you have ever learned how to make metal detectors, you will agree with me that they work by emitting radio waves. When it detects secondary alerts that is when a metal is detected. This tool provides information about this fact by way of a sound sign. When it is turned on, an electromagnetic effect is triggered on its search head, which propagates into the surroundings. If a metal falls inside the range of a search coil of a metallic detector, then eddy currents are triggered on its surface under the effect of an electromagnetic field. Those currents create a counter electromagnetic field, which reduces the strength of the electromagnetic field of the coil. The information on the statistics received is processed alerts the presence of a metal.

Technology integrated into metal detectors

Both new and used metal detectors generate a magnetic field across their coil transmitters. As a result, the goal also has a magnetic flux underneath the coil, which catches the coil receiver. Then this magnetic flux is transformed into visible records at the display and a valid signature. VLF metal detector generates current within the coil transmitter and adjustments within the segment and voltage amplitude at the receiver to show the presence of metallic objects. However, pulse induction metal detector (PI) are prominent since it generates a transmitter cutting-edge that turns on for some time after which it suddenly turns off.

Note that the coil subject generates pulsed eddy currents inside the object, which can be detected by way of reading the attenuation of the waves caused in the receiver coil. This cycle repeats constantly.

What to consider when shopping for a metallic detector?

Whilst buying a metal detector, most customers prefer buying the pricey devices and believe that they are worth paying a big sum of money, and all precious items will be discovered from the ground. However, this is not the case; there are cheap metal detectors that offer exceptional results.

Firstly, you should ask yourself questions such as what gadget do you know how to use and what form of search are you planning to undertake? How much does a metal detector cost? Or how does a metal detector work? Also, while buying a metal detector, mainly when the quest is only a hobby, it’s far better also to pick up the less luxurious detectors. There are simple characteristics that have to be considered when shopping for the best metal detector. For instance, the best all-round metal detector should consist of the screen, discriminatory, search masks, coil, and other additional features. In comparison to the entire depth of metallic detectors, soil metal detectors are geared up with a display that displays the settings and presentations statistics at the findings.

Normally, the screen of the soil metal detector displays the records that the search engine is programmed to find. Below are the key things to put in mind before you buy metal detector:

  • Display of the discriminator statistics and seek masks allow you to determine the type of metal detected comfortably.
  • Pinpointer and depth to the goal indicate the precise willpower of the placement of the target and the intensity of its incidence.
  • Extra settings, consisting of an indication of the battery life, the set sensitivity of the detector.

All other statistics are secondary characteristics that demonstrate the consolation of using a certain metal detector.

What add-ons do you need with a metal detector?

The majority think that the treasure hunter does not need anything else besides a metal detector. However, this is not the case. Below are some of the additional accessories needed by a treasure hunter:

  • Shovel – This is the second vital device required by a treasure hunter. Indeed, without a shovel, you’ll not locate the treasure found with the aid of the best metal detectors. The ideal shovel should be comfortable, robust, and balances in the hands. Additionally, it should be compact. It helps to keep it hidden in a backpack. Also, ensure you sharpen it after buying.
  • Headphones. In case you want to dig critical unearths from the depths, then headphones are required. Frequently susceptible signals are skipped because of poor listening to the sound from the tool. And, for example, now not some distance from the toll road, for the duration of the wind within the forest, they will shop from immoderate noise.
  • Pinpointer – It is such an incomprehensible word, but a completely useful device. It determines the exact place of the goal, right down to the millimeter. All through, excavations are feasible inside the perimeter of the dug hole to keep pinpointer and find out the area of the item. It additionally substantially speeds up the hunt system in a sticky piece of soil. In addition, it is far always in hand and has a superb reaction to the metal.
  • Bag – It could be small and simple, but it goes a long way to ensure your metal detecting finds are safe in the pockets. For comfort, as opposed to a bag, you could use the patch pocket, that’s first-class attached to the trousers. So, the “treasure” will no longer be misplaced, and you may no longer carry a bag with you.
  • Backpack – It is ideal for lengthy journeys.  Before buying a backpack for a metal detector, you should ensure you pick a completely reliable and roomy version. It should be capable of fitting everything including the metal detector, a shovel, and the different stuff you need. Also, remember that you may have to put it on your back all day, so the backpack needs to be at ease, not to avert your motion.
  •  A knife and a flashlight– These are irreplaceable items while on a treasure hunt.

How deep can a sensor go?


So, at what depth will the sensor go? Normally, the depth in the majority of good metal detectors is just 20-30 cm and, in some cases, 40-50 cm, especially in powerful instruments. All metal objects are located deeper than fifty cm; in spite of everything, over ninety-nine of these objects are mostly lost things.

Imagine excavation every time over half a meter? Generally, sensible devices will react to longer distances – up to 1.5 meters. However, this can only apply to an oversized size such as a car. Coins can see a rare device within the ground to a distance of more than 40-50 cm deep. They are, of course, special metal detectors that see a depth of many meters. They are also created to search for massive metal objects only.

Where to search with the detector?


The best place to search is where there was a village settlement a long time ago. They are thought to be one of the best places for metal detecting. It is mainly because such places are quite straightforward to search out on the map, and that they occupy a huge area, and thus the losses in those times were plenty and, therefore, undertaking a search should be fundamental. You will be able to get coins from the seventeenth to the 20th century. Bazaars and fairs also are a good place to look. The hunt for coins in such places is going to be a pleasure. However, the problem is that such places don’t seem to be marked on the map, and also the digger has to grasp the precise coordinates.


One of the most profitable places, together with fairs and bazaars, are inns. They were settled in the main close to the doorway or exit to the village. A sufficiently sizable amount of coin metal detectors is realized in these areas. There are also other roads that are connected to districts and different villages, farms, and counties, which make it easy to access. Other nice places where you’ll be able to explore for treasure additionally are fords and crossings. The ford people were busy with other things, and often, nobody paid attention to the loss of coins. Coins were occasionally lost at the bridges.

Places of war in World War II are also one of the best places to hunt for treasure. Hunters will come across bayonets, cartridges, helmets, and guns. Excavations ought not to be on good metal detectors but also dispensed and rigorously, as there’s an opportunity to come across an entire charge, having lain within the ground for many years, it will still explode
