Today we will discuss with you such a device as the detector. The principle on which the constructed work, that is, the induction balance system (impedance), was opened by the German physicist in the nineteenth century. Object detection occurs in a neutral or weakly conducting medium due to the conductivity of metal objects. In other words, when voltage is applied to the coil creates an electromagnetic field, irradiating a specific search field. Under the influence of this field, metal objects caught in the search region, starting in turn, generate fields. Which leads to a distortion of the original electromagnetic field – that “detects” the device, feeding the audio signal to the user.
The first application of the detector as the device was carried out in the United States in the early twentieth century. The developed device was to combat the theft of metal parts in factories.
Electromagnetic coil. It then creates a search field.
Rod. It contains all the elements of the device. From its ergonomics and weight depends on whether the search be fun.
In many ways, the setting of the metal detector individually. But the basic stuff is still there. The first thing you need to turn the device on and set sensitivity level. The higher the level, the deeper the “breaks” field. But at the same time increasing the noise level. Another important feature is a “discriminator”. It can be used to search for selected metals. That is, with the help of this option we do the device is “deaf” to such things as nails (iron), foil (aluminum) and the like debris. It is also worth remembering that this option reduces the sensitivity of the device.
The remaining functions depend on the degree of “tricked out” detector. Here pinpoint (accurate target detection), and the balance of the soil. In General, for your money – any whim.
In practice, the detector used in many areas of life. For the military, he became a mine detector, security – inspection, compact, manual or metal detector great framework for the medical device, which are looking for metal in the human body. Archaeologists use metal detectors to search for artifacts. And for some people the metal detector became a distraction from routine, entertainment, hunting and fishing, we can say, a hobby. These people most of my free time in the fields and woods in hopes of finding the TREASURE. Do not disdain and beaches in search of lost coins and jewelry.
For such people, there is a segment of metal detectors designed to search for these treasures, a variety of jewelry and coins. Depending on the purpose of the search, they are ground, underwater or deep. Ground determined the subject at the top of the soil up to 1 meter, but the depth to cope with 4 meters.
And anyway, who among us has not ever dreamed to find a real ancient treasure that was buried many centuries ago. To hold an ancient coin or the sword of the warrior. In principle, nothing keeps you from realizing your desires. All you need is to buy a metal detector and a little “dig” in the histories of their field, for determining the location of the most ancient paths and abandoned villages, where many centuries ago, of seething life, and therefore lost a variety of things. And near the paths of wealthy people or robbers buried treasures. And maybe that’s you they’re waiting for.
If here with information about search locations we will not help – it depends on your desire and perseverance. The choice of detector for the beginning of our search system is easy. Depending on the budget of the purchase, consider the several models in classification from “initial” to “professional” brand TREKER.

Rod of the metal detector consists of three parts. Going to the bar very quickly, on top there is padded armrest and handle. The control unit is attached to the bar with just one screw. In the controls we will see the analog indicator arrow (which tells more about the depth than the conductivity of a found object) and handles configuration and management. Far right is the handle, the “discriminator”.
The average pen is responsible for setting the sensitivity of the device. Left — turns on and off the device and adjust the volume level of the signal response. The device is equipped with a 190 mm monogamously. The mass detector 0.91 kg. That is, it is, in principle, virtually weightless. Also the front panel has a red indicator that tells about the discharge of the supply battery. Yes, the power is supplied from the battery of type “crone” 9V.
Setting a metal detector is only possible in manual mode. To do this, use the right regulator produced by activating the appliance and setting the desired volume. Next, using the Adjuster SENS set the sensitivity of the instrument. The handle “discriminatory” in the beginning of our journey not touch. At first we should practice in finding anything that “rings”.

Rod of the metal detector consists of two parts. In the controls we will see the analog indicator arrow, and also handles configuration and management.
Far right is the handle, the “discriminator”. Extreme handle on the left turns on and off the device, and adjust the volume level of the signal response and adjusts the sensitivity of the instrument. On the handle there is a red button to “reset” the display and setting the sensitivity of the device. The device is equipped with a 180 mm monogamously. The mass of the detector is 0.7 kg. that is, even less than the previous model.
Also the front panel has a red indicator that tells about the discharge of the supply battery. Power is supplied from the battery “crown” 9V.

Rod of the metal detector consists of two parts. Going to the bar very quickly, on top there is padded armrest and handle. The control unit is identical to model Treker GC-1065 — we will see the same analog indicator arrow, and also handles configuration and management. The only difference is the location of the regulators.
And so setup and management are identical. The device is equipped with a 165 mm monogamously. Mass of 0.9 kg. detector Powered from a battery “crone” 9V.

Is an improved model Treker GC-1016A. With the device already not coil 165 mm, 190 mm and Weighs 0.95 kg. metal detector is Powered by two batteries “the crone” 9V.

The bar consists of three parts. The lower part is made of high impact plastic, middle and top in anodised aluminium. Unit weight is 1.25 kg. Armrest are big and comfortable. Pads on it made of neoprene. Therefore, even a very long “COP” is not a burden to you. Equipped with a metal detector waterproof monocausal diameter of 215 mm. In the upper part of the detector is monitor, on the screen where you can see the depth of the subject.
At the top of the screen there is a scale of “exception” for discrimination of the selected item from the search. The device is powered from eight AA batteries or a rechargeable battery. The three-tone sound indicator. Just above the screen is the “brain” of the detector. It has all the elements of configuration and management. The left knob switches on / off the device and adjust the volume level of the signal response. Before starting, you need to set up on the ground. For this there are two options – manual and semi-automatic.
Select net from metal objects, place and press the button “Mode”. Translate the device in the most sensitive mode “All Metal”, while keeping the coil at a height of about 3 cm from the ground. The balance control to the right, is exposed in position “P” and press the GND Track.
Manual setting is more accurate – using the balance control, find the sensitivity threshold. An important condition of all settings is the lack of metal objects under the coil. All, the device is ready for operation.
Practice shows that the main part of the treasure hunters find coins at depths from 5 to 15 cm That is for beginners “diggers” all the models is more than sufficient for “Packed with hands”. They are easy to use, cheap compared to more famous brands and quite functional. And in many ways the success of the search depends on the skill and luck of our search. So, go ahead, gain experience, and your treasure you will most certainly find.Recent search terms:
