Detect Gold: how?

 

Native gold (whose chemical symbol is the symbol “to the”) comes in two forms, the flakes and nuggets. You should know that glitter are not detectable with a gold detector because their size is too small: the only way to find them is gold panning. Gold nuggets are, they, detectable from a weight of 0.1 grams and with a diameter of 2 mm. As their size, the more they will be detect in depth. Of course, to find the nuggets of this precious metal in depth, must be that gold detector is perfectly adjusted and that its signals are correctly interpreted.

Gold VLF detectors

 

The vlf are very effective to detect gold, on the condition that the soil is not too mineralized (presence of magnetite). In the case of strongly mineralized soil, the vlf will feel the ground as the metal. It will be forced to discriminate against the ground, thus losing in detection depth. The advantage of the vlf is they have a metal discrimination, allowing for example to detect gold without detecting iron, which saves time, and so in the end a larger surface surveyed per day. With a vlf, plus the size of the sensor head increases, and more deeply detects large targets.
In return he became less sensitive to smaller targets. Therefore, to detect both large and small nuggets remain in a standard diameter between 20 and 27 cm. The operating of a vlf frequency ranges from 4 khz to 18 khz. The best vlf for gold will be so-called devices ‘high frequency’, i.e. having a frequency between 14 khz and
18 khz. This high frequency make them more sensitive to certain metals, in particular gold. To reduce susceptibility to mineralization of soil, it is necessary to equip the vlf high frequency of a
sensor head double D. The most suitable models are:

gold maxx power and deus (manufacturer French xp).
garrett at gold.
xterra 705 gold, Minelab brand.
tesoro tejon and easy gold.
Gold detector: inductions pulsed, otherwise called ‘PI’.

Pulsed inductions, unlike the vlf detectors are not sensitive to high soil mineralization. Heavily mineralized ground they detect no deeper than a vlf, notably on the crippled grounds of magnetite. In hand they possess no discrimination of metals, they will be unable to differentiate iron gold, resulting in a big loss of time if the gold field is polluted ferrous. The most effective model for gold is, for the moment, the gpx 5000 of minelab. This unit is available with head dd or mono. The greater depth of detection will be reached with the mono heads. The other difference with the vlf is that even by increasing the diameter of the head to detect deeper large targets, a pi will continue to deeply detect smaller targets. Accordingly the diameter the most suitable for the detection of a pi head ranges from 30 cm to 40 cm. Other models are also recommended to detect gold, do not hesitate to ask advice by emailing us or by phone at 04.42.28.64.57 (France).
Find gold in Africa?

Africa is a vast territory of more of 30 million km2. The soil of this continent is rich in raw materials and many gold mining. Major gold mines located in the country of South Africa (198 tons extracted in 2009) and Ghana (86 tons in 2009) but many countries engage in the exploitation of gold mines each year and recently with new African countries open gold mines: Botswana, Congo, formerly Zaire, Guinea, Zimbabwe… The means put in place to extract gold are so huge. Besides, individuals seek to gold, with gold panning, or with the help of a metal detector for gold. Many testimonies attest to each day of the usefulness of having a metal detector to find gold.
