Different types of coils for metal detectors

Do you want to have a really successful treasure hunt? This time we will give you the keys to really work.

First of all, you must have a good metal detector, you must learn to use each of its parts before going on an adventure and when that day comes you must be well equipped with excavation tools suitable for the territory you choose.

But one last detail is still missing: having a good coil. Even if you don't believe it, the key to a successful search is the coil, because this will determine the search scope and delimit the large or small objects you wish to find.

In this article you will know the different types of coils, their operation and we will give you a top of the best coils we have for you.

Types of coils and their operation

The coils are constituted by an electromagnetic field. If the coils are small in size, they will be able to reach a more superficial level, but their field will be concentrated in the search for small traces, while the coil will be larger, it will have the capacity to go to a deeper ground and will be in charge of searching larger objects.

Small coils are recommended to scrape small pieces of gold; when it comes to relics or larger objects, larger coils are recommended.

Concentric or coplanar coils

They are the most used coils since it has a good electromagnetic field. The great feature of this type of coils is that they have double winding one internal and one external. For this reason, they are known as "Concentric". This type of coils generates an electromagnetic field of a conical shape, with the highest density of the force of said field tending to go to the center and to the front.

Among the advantages of the concentric coil is that it is very sensitive and works very well when discrimination is activated in the metal detector. However, it should be used with delicate and precise movements in its manipulation to be able to locate something.

Its disadvantage is that it can become unstable in highly mineralized soils.

Concentric elliptical coils

Elliptical coils are also concentric and because of their elliptical shape they are very efficient for working with them when gold buried in various fields is to be detected. Its disadvantage is that due to its shape the pin-pointer will be more difficult to manipulate because the electromagnetic field will be more concentrated to the side.

Double D coils

These coils are named after the uppercase "D" shape they have on one side and the uppercase but inverted "D" shape they have on the other. A great feature of these coils is that they work up to 70% better than a concentric coil in mineralized soils.

The disadvantage is that these coils have a fairly small electromagnetic field, the two are concentrated in the middle and give the appearance of a blade, which means that when searching you will have to do more movements and sometimes it is difficult to locate treasures that are near a wall

Double D butterfly coils

They have a larger size works to locate objects in greater depth. This coil has a design that will allow you to get closer to the walls.

Monoloop coils

They have only one winding that will act as emitter and receiver. Normally these coils are used in gold detectors that work freehand and their size has to be consistent with the search.

There is a slight variant of these coils and they are the coaxial coils that are normally used in VLF detectors and are the three-dimensional linear analogs of the concentric coil.

Mars coils for metal detectors

Mars coils have been designed with the best technological advances that make them more resistant to harsh environments, maintaining optimal stability in highly mineralized terrain and running underwater.

There are several models and sizes and its compatibility go with almost all brands and models of metal detectors.

Mars MD 15 "Goliath DD Waterproof coil

It is compatible with Garrett ACE ACE 200, ACE 300 and ACE 400 Water Resistant detectors and is protected against electrical interference. It works very well in areas with strong vegetation. It is also compatible with other models of metal detectors.

Mars MD Discovery 13 DD Waterproof coil

The 13 "Mars MD Discovery coil optimizes your search with an excellent balance in various fields and is one of the favorites for having a greater range compared to the other coils. It is compatible with the Garrett ACE 200, ACE 300 and ACE 400 with Garrett GTI 1350, GTI1500, GTI 2000 and GTI 2500 and other models.

If you are interested in having a successful search then you must purchase a Mars coil visit our website and if you have any questions contact us at WhatsApp +1786-909-3320

Detector Online Training

With your new detector, you will receive a Quick Start Guide, a valuable resource designed to guide you through the essential steps of operating your new device seamlessly. This user-friendly guide is tailored to ensure that even beginners can quickly grasp the fundamental functions and features.

For those seeking a more profound understanding, a comprehensive manual accompanies your purchase. This detailed manual delves into the intricacies of your detector, providing a wealth of information for users eager to explore advanced settings and capabilities.

However, the pinnacle of expertise in harnessing your detector's full potential lies in professional training. While guides and manuals offer a solid foundation, professional training takes your knowledge to the next level. Through hands-on instruction and insights from seasoned experts, you'll gain a deeper understanding of your detector's nuances and unlock its optimal performance.

During the individual training, our detector Expert addresses your wishes and questions, provides you tips and tricks and helps you to improve your chances of success with your detector.

  • Theoretical introduction
  • Overview of the functionality and operating modes of your detector
  • Using the detector on the test field
  • Tips and tricks for advanced users
  • Improving your measurement procedure
  • Evaluation of the scans on the detector display
  • Answers to your questions

In addition to a general introduction to the functionality and operating modes of your detector, the detector Expert explains how to use the detector efficiently in the field. In doing so, he can correct small errors during the measurement and advise you on special features of your search projects.

You will learn how to check your measurements and further improve your scanning technique independently. You can also draw initial conclusions about potential target objects in the underground.

  • Service & Support: for entry-level, experienced and professional detectorists
  • Schedule: After you add the paid training, we will contact you to schedule your training with our expert.

Trainings are charged per hour! Additional costs may apply for training sessions. For special requests please contact us at
