What is the depth of detection
Depth depends not only on the appliance and the coil, but also from the object (material, mass, form), from its position in the soil and soil properties. I.e. in each case the depth is different from any "standard" tests very strongly, so its manufacturers never point-it's not quite honest publicity stunt domestic sellers. Garrett believes such tests are absolutely useless and does not conduct them. Instead, for its depth of detection devices (sensitivity) results in conventional units, which provide a glimpse of devices relative to each other, which is much better.
professional metal detector to find gold nuggets, the timing should not be used when searching for large, Search for gold using the metal detector is an intriguing and lucrative process and does not necessarily go for the nuggets in distant lands! Any beach on the sea or Lake has in its depths a myriad of precious metal, which can be sent and precious stones. Essentially a metal detector is a device that distinguishes the presence of metal underground with no direct contact with him. These devices emit certain wave and take response data to inform search engines about finding using sound or Visual signal. When connecting from the search tip the appliance generates electromagnetic fields that extend and interact with various substances.
More often than not find gold with a metal detector is carried out on the beaches. To search the beach seas, rivers and other water bodies will fit any modern metal detector. Because they all now have the two most essential properties to search for on the beach: discrimination (ability to define and separate the iron from non-ferrous metals) and sealed search coil for metal detectors.
Many metal detectors are equipped with submersibles, drenched compound waterproof search coil. It turns out that the coil can be easily lowered down the cord and Rod, it is precisely this distance and need not to soak the control unit with a metal detector (usually this is 30-50 cm). It is very important to know! Control units of the detector of conventional ground metal detectors are not sealed, and lowered them in water cannot be, and is also not permitted the ingress of splashing!
Thus, it is possible to search for articles of precious metal in water (not far from the shore), lowering the coil unit into water. Metal detector-amphibian Garrett AT Pro can be fully submerged to a depth of 3 meters.
It is very important to know what to search for gold on the beach do not need a very expensive metal detector, suitable for almost any, because there are many finds to be not very deep and is located in the range.
However, professionals use special models of metal detectors, sharpened on the discovery of gold. For example, the metal detector Garrett AT Gold or Fisher Gold Bug DP. What is the difference between metal detectors for gold from the ordinary?
Metal detectors for gold work on the principle of selective discrimination metal detector on the screen graphic scale is divided into segments, each segment corresponds to a certain metal. You can turn on and off segments of the search program.
Equipped with highly sensitive coil, allowing to pinpoint the smallest goal. Coil is tight, that allows to search for gold in the water.
Metal detectors for gold have the function of compensation impact of high salinity in the soil, which helps increase the accuracy of the discriminator. To search for gold we recommend you to use Garrett AT Gold.
