Metal Detector – Purchase Guide, Opinions and Analysis in 2018

Metal detectors are a perfect excuse to spend a pleasant time looking for “treasures” both in the countryside and on the beach. However, for this search to be effective it is important to bet on a model that offers you the power and range necessary to work comfortably. Obviously we are not going to bet on a professional model but at least one that is capable of satisfying your curiosity. This is what the Garrett Ace 250 model offers, the one most recommended by consumers. This product has a wide range of scope as well as a special processor that allows us to distinguish between different types of metals, so that the scrap does not become a false alarm. Another interesting model is the detector X-Terra 305, which with its control screen and interchangeable plates allow to modify the range of operation and control the metals to locate. All in a light weight of only 10 kilos.

What is the best metal detector in the market?

Tracking beaches and mountains with the intention of finding lost metal objects, as well as relics or ancient coins is not just a hobby, but a passion. That’s why we’ve prepared this guide to buy the best metal detector, an instrument that uses electromagnetic pulses to find metal objects under the ground. Our main objective is that you can make a comparison of metal detectors and finally choose a good and economical one.

Uses of the metal detector

We all look like interesting machines, but for whom are these devices recommended? In general we could say that these devices are ideal for the most curious and adventurous spirits, in fact many people search almost daily and there are communities in social networks that are dedicated to sharing photographs and stories about their travels and findings.

Searches include relics, native metals in pips, coins, etc. In 2008, for example, a Spanish diver named Mike DeMar, found a golden chalice on a Spanish ship that had sunk almost 400 years ago. On the other hand, the British Mary Hannaby found with her metal detector a gold earring for which she obtained around 50,000 Euros. It did not hurt, do not you think?

Of course not all of us have had the same luck, but many of those who practice treasure hunts do not do so much to get rich, as to hang out. This is a hobby that can be relaxing and although they are not very valuable, you always get interesting things. In Spain it is normal to see someone on a beach looking for lost objects under the sand at the edge of the beach. At the end of the afternoon, when the bathers leave, some prospectors go out to try their luck.

What type of metal detector is better?

At this time you may be thinking about the price, but before asking how much it costs, let’s see what options we have available.

Metal detectors can be Very Low Frequency (VLF), or pulsed. The former have the advantage of having discrimination circuits, that is, they can specifically detect the type of metal we are looking for, while the pulses do not. However, this does not mean that metal detectors, whether expensive or sophisticated, will be infallible. Aluminum, for example, is often confused with gold, so that whatever the detector is, it will make us take out another can of garbage.

Of course, detectors capable of discriminating, like some models of the Garrett brand, as well as others recognized in the market, can be a bit more expensive, but many people think they are worth it, depending on the use that is given. If you think of looking for treasures frequently, you will surely prefer one with a discrimination system, while if you are only going to use it very sporadically, it is preferable not to spend a lot of money, especially if we are beginners in this search for treasures.

Important characteristics

Detection range

Although the manufacturers of detectors offer in their advertisements this or that depth to which the detector can reach, the great truth is that this is very complex to define. There are many things that influence; for example the type of soil, because not all have the same amount of minerals. In this way, a detector that offers to find objects at a depth of 25 cm may be able to do so in a soil with little mineralization, but in a highly mineralized soil the sensitivity may be about 10 cm or less. The first thing is to be clear about the use we are going to give you.

Another of the things that can positively or negatively influence the detection capacity is of course the humidity. A wet floor causes metals to leave a “halo” that increases the chances of detecting it. This except in gold because it is a metal that does not rust or generate this effect around, even if the earth is wet. As is known, some metals give more signal than others. Among the easiest to find are silver and lead, while the hardest is usually iron.

Plate size

In this case, small plates are recommended to look for very compact objects. For example, if you want your detector to be able to find a chain, you have to have a dish of less than 25 cm, and vice versa, if you are only interested in larger objects, you will need a larger dish.

What is the best metal detector of 2017?

Acquiring a metal detector is a great help, so you should not take your choice lightly, and it is convenient to review several proposals, so we have reviewed five options that have been promoted by users so that you choose the most convenient for you.

Recommended Products

Garrett Ace 250

This is a detector that works with a 12-segment graphic cursor, which gives a wide range of sensitivity to detect metal objects anywhere.

How to use a metal detector

Let’s begin by defining a metal detector as an apparatus that is capable of locating and detecting metallic objects by means of a system of electromagnetic impulses. In the beginning they were used mainly to detect the presence of mines and also precious metals such as gold, however, they are currently used by archaeologists, in mines and to complement high security systems in different places such as airports.

Low frequency detectors

They are usually the most commonly used and usually have one or two frequencies. They have a high sensitivity to minerals such as silver and copper. Although they have a good depth of reach, you should verify very well the mineralization of the land where you want to use them, since this factor will directly influence the performance and stability of this type of detector. They are usually quite simple to use by anyone.

Multifrequency detectors

You can have between 17 to 28 search frequencies with this detector; working equally with frequencies between 1.5 to 100 KHz, which will considerably improve its operation and its level of stability, regardless of whether you are in highly mineralized areas. They are considered one of the most expensive, but you can work more quietly and with fewer interruptions than with other more affordable models.

Pulse induction detectors

They are ideal for you to use them in the water, especially if it is salt water. You can also use them for searches on beaches and areas where there is not much scrap nearby. Some of these models have armrests, so you can handle them more comfortably while you are walking. You must go around the place and move the dish to detect the objects, since the pulse or warning sound will not be fixed when you find them.

Detectors of boxes or antenna

They use an interesting transmission / reception system. This type of detectors in practice will help you distinguish ferrous metals from non-ferrous ones. They are not recommended if you want to look for very small objects and you should bear in mind that they are very influenced by the terrain and by the characteristics that it has. They are usually used by geologists, professional treasure seekers, and utility companies.

Detection range

There are factors that you must take into account to be successful in the search with your metal detector. The main factor that you must take into account is the mineralization of the land where you are. There are detectors that reach a depth of up to 25 cm and can reduce their sensitivity to about 10 cm in highly mineralized areas. The important thing is that you review the range offered by your metal detector and the use you are going to give it.

Plate size

You must take into account that, depending on the type of coil or antenna that your detector has, you can locate objects of smaller or larger size more easily and quickly; that is to say, the larger the coil you will detect objects of larger dimensions and with smaller coils you will detect smaller objects.
