How to choose the best metal detector for gold
From time immemorial, gold was considered synonymous with wealth and power . The amount determined viability and prosperity of man. Previously, gold is a measure of the cost of any product. Despite the advent of paper currency , people still continue to search for gold, as something very valuable in life. Perhaps any treasure hunter wants to find if not a huge chest of gold , at least a couple of coins . No way to search and industrial production of this precious metal requires quite a lot of preparation , as well as patience and luck . The most essential tool searching for gold – is the metal detector or the detector , if we speak properly .
Naturally, every self-respecting manufacturer of metal detectors is interested in great demand for gold and therefore creates a model specifically designed to detect it . For example, in 1986 Minelab has developed its first metal detector for gold. Now it makes this more modern model GPX- 4800 , GPX- 5000 , Eureka Gold. White’s company produces a model for gold GMT, at Fisher – a model of Gold Bug II, at Garret – Scorpion Gold Stinger, at Tesoro – Lobo Super Traq. Huge selection of models is partly connected with the fact that most of these companies are located in North America, where it is not commercially search for objects of gold has always been permitted by law and even encouraged . It is for this reason that in North America attracts a large number of immigrants with a dream to get rich.
Actually standard metal detectors are also able to detect gold, so what’s the feature of these models? The fact that they are designed specifically for the detection of minute objects , to which and can be attributed primarily gold and nuggets . Who would not want to find a nugget the size of a fist ? But, unfortunately , it happens quite often. Most often comes in the form of gold sand and discover it can not all metal detectors . High sensitivity to the smallest objects , like golden sand , is achieved by using higher frequencies. Almost all standard instruments for detecting metals operate at a frequency range of 6 to 8 kHz. Models same metal detector for detecting the gold operate at frequencies from 15 kHz to 71 . For example , the work of Eureka Gold metal detector is possible on the three frequencies – 6.4 , 20 and 60 kHz. Others have a fixed frequency : GMT – 48 kHz , Gold Bug II – 71 kHz , Scorpion Gold Stinger – 15 kHz , Lobo Super Traq – 17.5 kHz. A rather large spread of frequencies between different models. But the search for gold and handled by different people with different tastes. And the budget does not allow each person to buy a high-sensitivity model . Furthermore, the conditions are different to find somewhere with a certain frequency model would cope with the task better than another .
All metal differ in characteristics, a set of accessories ( a coil , etc. ) and cost. Many models of metal detectors for gold practical enough to look at, to facilitate not have a display . Even though it may introduce confusion about its quality , but it is configured using the control panel with the regulators . When an object is detected the operator hears a voice message a certain tone from the speaker or headphones.
Model GPX- 480 , GPX- 5000 GMT and have a display that allows you to visually adjust those controls that are on the control panel of metal detectors to search for other gold objects. As with most modern devices when an object is detected , the display shows VDI, which displays the value with the “+ ” , if found non-ferrous metal , and the sign “- ” if found “black” metal.
Number of miners among the common masses hunters small, so production companies do not need to develop a huge amount of metal detectors designed for gold prospecting . Only once developed such a model , they are almost completely satisfy the needs of customers.
