The search for precious metal has always attracted people. Agree, it is nice to find gold coins or jewelry, nuggets. In this material, consider which are the best metal detectors to search for gold, conduct a comparative analysis of the most popular models and help you choose a device with the optimal combination of cost and parameters.
When wondering which metal detectors see gold, it is necessary to consider in detail the parameters of such equipment and available options. Gold coins and other products are excellent at detecting devices that work at a high frequency, that is, above 14kHz. The advantage of working at this frequency is the ability to detect small objects, such as earrings, rings, coins.
If you are wondering which metal detector is looking for gold, then any device can find a gold ornament or coin, it all depends on the user's settings and the capabilities of the device. If you set out to find gold jewelry or coins, then you need to choose models of devices that weed out signals of black metals that have no value.
So, let's try to figure out which metal detector is better to look for gold? The search for gold products has some specificity. Gold in terms of conductivity and scale of metal discrimination has similar parameters to oxidized iron, for this reason, an extended range of black metals should be provided in the metal detector for gold coins. Coins and jewelry made of precious metal in most have small sizes, so the device should also have a high sensitivity to small objects.
metal scanner detector is designed to accurately locate everything Long Range metal detectors with ingredients long-range detectors gold detectors water minerals you can see the details.
When asked how to choose a metal detector for gold, we will answer that in order to effectively search for coins and jewelry made of gold, the device must have the following functions:
Discrimination. Since the precious metal is on the verge of parameters of black oxidized metals, finds from it at a depth of more than 20 cm can be perceived by the device as black metal. In particular, this applies to old gold and precious metal with a low breakdown. For this reason, a wide range of searches must be provided for the clear separation of precious metal and rusty products in the metal detector. Thanks to this function, you can make clearer adjustments to the search for gold coins and jewelry;.
Long Range Finder 42 compass Finder 42. The frequency may differ in the search for gold, copper, silver and iron. The sensitivity is a medium range of 1000 meters/distance/manageable. Sensitivity depends on the size of the object. Machine
If the device is used only for such purposes, there is no special need to purchase an expensive unit. Such tasks will cope with budget models - entry-level detectors. They are compact devices on a telescopic rod with a coil. Detection sensitivity is variable: it ranges from half a meter to several meters. According to this indicator, the entry-level devices are inferior to professional ones. Therefore, such devices are more suitable for beginners and for search work at a low depth.
Radar parts are technical details related to radar components and their ability to detect returning energy from moving dispersors - determining the position of an object or an obstacle in the environment. This includes a field of view in terms of body angle and maximum unambiguous range and speed, as well as angular, range and speed resolution.
Profiling provides a vertical sectional view of the subsurface environment along the path of measurement in real time. However, the role of the vertical coordinate performs during the pulse to travel from the transmitter to the boundary of the reflecting object and then to the receiving antenna. To convert this “temporary cut” in the real depth is necessary to estimate the velocity of propagation of electromagnetic waves in the environment and take into account the location of the point of reflection about the antenna device.
Propagation velocity of the probe pulse needed to assess the real depth of the objects can be found directly from the temporary cut in the presence of local or on the track linearly extended across the road subsurface object forming at radarogram characteristic hyperbolic trail. Solution corresponding asymptotes of the hyperbola depends on the speed of wave propagation in the medium. Function determining the speed of propagation of electromagnetic waves in a medium according to the diffraction image of a hyperbolic local object in the device has not been implemented and it is expected to available software systems GPR data processing on a computer.

test a new kind of GPR, This device seems to be very promising for the detection of treasures. Indeed, unlike the current ground radars, which work only with a single frequency, the Geovizer uses simultaneously 14 different frequencies. It is a georadar induction electromagnetic user. Its performance will not be reduced by the moisture of […]
Authentic ground radars, also referred to as GPR, allow the detection of metal targets and the cavities at inaccessible depths to other detection systems. But beware, a GPR is used not as easily as a metal detector. Indeed, there are a number of constraints to respect. Field must be completely dry, even in depth, because […]
